Coronavirus (COVID-19) | April 04, 2020

Hicham Skali, M.D., a staff cardiologist and member of the Non-invasive Cardiovascular Imaging Program at Brigham and Women’s Hospital (BWH), and at Brigham and Women’s / Massachusetts General Health Care Center at Foxborough, explains the new recommendations from the American Society of Nuclear Cardiology (ASNC) and from imagers in China and Singapore. The ASNC created a best practices document for nuclear cardiology laboratories during the novel coronavirus (COVID-19, SARS-CoV-2) pandemic. The suggestions in the guidelines can ally to any imaging modality, including computed tomography (CT), MRI and ultrasound. 

Skali elaborates on the following points in his discussion, which are specific recommendations in the ASNC and SNMMI COVID-19 guidance document:
   • Rescheduling non-urgent visits
   • Rescheduling elective surgeries and procedures
   • Using separate spaces for patients with known or suspected COVID-19 to prevent spread
   • Ensuring supplies are available
   • Promoting use of telehealth
   • Screen staff, patients and visitors before they enter the department
   • Minimize non-essential visitors into the department
   • Record symptoms at the start of the shift
   • Use personal protective equipment (PPE)for healthcare personnel
   • If available, use PPE for patients due to concern of asymptomatic transmission of COVID-19
   • Maintain strict hand hygiene
   • Maintain 6 feet distance in all patient/staff interactions when possible
   • Work remotely whenever feasible, especially with ready studies
   • Rotating staff schedules for on-site and off-site work
   • Use of rest only studies if possible
   • Use of half-time SPECT to speed exam times
   • Use of PET if available to speed exam times

Skali served as the moderator in for the ASNC on demand webinar COVID-19 Preparedness for Nuclear Cardiology Labs: Insights from the US, China and Singapore.

Regina Druz, M.D., FASNC, a member of the American Society of Nuclear Cardiology (ASNC) Board of Directors, chairwomen of the American College of Cardiology (ACC) Healthcare Innovation Section, and a cardiologist at Integrative Cardiology Center of Long Island, N.Y., explains the rapid expansion of telemedicine with the U.S. spread of novel coronavirus (COVID-19, SARS-CoV-2).

Druz spoken on the unprecedented expansion of telemedicine in the U.S., which more use in the last two weeks since states started calling for shelter in place orders, as opposed to the past two decades. The Centers for Medicare and Medicaid Services (CMS) previously only reimbursed for Telehealth in rural areas it determined had a shortage of doctors. However, in early March 2020, CMS dropped the geographic requirements and allowed Telehealth usage across th country as a way to mitigate person-to-person contact and keep vulnerable, older patients at home for routine check ups with doctors.

Druz has subspecialty certifications in nuclear cardiology, adult echocardiography and cardiac computed tomography (CT) and explains how Telehealth can be used to pre-screen patients and get patient sign off on procedures prior to coming in for an exam, helping speed the process in the hospital and limit personal contact.

Concerns about the rpaid spread of COVID-19 also has driven many radiology departments to convert to wider use of teleradiology to allow more radiologists to work from home and reduce person-to-person contact within the hospitals.

Teleradiology | March 26, 2020

John Kim, M.D., chairman, Department of Radiology, THR Presbyterian Plano, Texas, and chief technology officer at Texas Radiology Associates, explains the use of teleradiology during the novel coronavirus (COVID-19) outbreak in the U.S. The radiology group is part of Collaborative Imaging, a radiologist owned teleradiology alliance that enables radiologists to read studies using secure web links and an app.

The rapid spread of coronavirus has increased the value telemedicine solutions to help prevent person-to-person contact and take some clinicians out of the hospitals to work at home or office locations. This includes the use of teleradiology tools to read images and communicate with referring physicians.

Telemedicine allows for the continuity of care within healthcare facilities and patients and allows for safe distance without sacrificing the quality of care. It also saves patients from spreading germs to others, like while on public transportation or in the doctor’s waiting room, and to the healthcare providers who tend to them. Televisits also only last an average of 10 minutes, allowing physicians to assess patients more quickly and easily. 

Coronavirus (COVID-19) | March 25, 2020

Jilan Liu, M.D., MHA, CEO for the HIMSS Greater China, explains how health information technology (HIT) was leveraged in China to help fight the outbreak of novel coronavirus (COVID-19, SARS-CoV-2). Her discussion includes use of artificial intelligence, telemedicine to reduce contact between people, using the electronic medical record to help record and track people COVID-19 patients had contact with, apps, internet hospitals, and how 5G networks helped speed up IT systems.

She was previously principal and consulting director of the Greater China Joint Commission International (JCI). As chief executive for HIMSS Greater China, Liu and her team made a significant breakthroughs with hospitals and the HIT industry in the greater China region to embrace international HIT standards, certification requirements and to rethink prudent approaches to IT investments and operations.

Ultrasound Imaging | March 20, 2020

Interview with Mike Stone, M.D., an emergency physician at Northwest Acute Care Specialists in Portland, Ore., director of point of care ultrasound education at Butterfly Network Inc., and and former chief of the division of emergency ultrasound at Brigham and Women's Hospital, Boston. He explains what clinicians look for in lung ultrasound to evaluate patients for plural wall thickening and areas of congestion inside the lung typical of pneumonia and seen in patients with novel coronavirus (COVID-19, also referred to clinically as SARS-COV-2). 

Small hand-held ultrasound systems may offer advantages over X-ray or computed tomography (CT), because the entire system can be contained inside a protective sheath, making it easier to disinfect the device rather than an entire imaging room. Point of care ultrasound (POCUS) systems also allow triage of patients in tents or other areas outside of the hospital where other imaging modalities are not available. 

Stone shares examples of COVID-19 ultrasound images from Butterfly Network POCUS system technology, which turns an iPhone into an FDA-cleared ultrasound device for multiple POCUS exam types. It is the first POCUS system reported to be used for triage and monitoring COVID-19 patients.

Magnetic Resonance Imaging (MRI) | January 06, 2020

Karen Ordovas, M.D., MAS, professor of radiology and cardiology at the University of California San Francisco (UCFS) School of Medicine and a Society of Cardiac Magnetic Resonance (SCMR) board member, explains how cardiac MRI can help in women's heart disease and to better define complex congenital heart anatomy. She spoke at the 2019 Radiological Society of North America (RSNA) meeting. 

She specializes in cardiac and pulmonary imaging, and has particular expertise in using CT and MRI techniques in cardiovascular imaging and the differences of presentation in imaging between male and female cardiac patients. Ordovas is helping advance education around heart disease in women and bring great awareness of quality tools to diagnose heart disease and how heart MRI can help. She also is heavily involved in the use of heart MRIs for pregnant women, since there is no radiation,  and patients with congenital heart disease where detailed imaging of the complex anatomy is required.

The use of cardiac MRI in congenital heart disease is common in serial imaging of patients with Tetralogy of Fallot (TOF), one of the most common congenital heart diseases for which patients are referred for post-operative magnetic resonance (MR) imaging evaluation. In the past few decades, surgery has proved successful, but most patients require repeat imaging throughout their lives and MRI can offer more detailed soft tissue imaging without the use of radiation.

Quickly determining is a stroke is ischemic or hemorrhagic is critical to the path of treatment. If caught early enough, TPA can be injected into patients to clear clots causing an ischemic stroke, but can cause massive brain damage or death if injected into a patient with a brain bleed. At advanced neuro-interventional centers, quickly determining the type of stroke is needed to know if they need to revascularize a patient or manage a hemorrhage.

This is a demo of the EOS orthopedic X-ray imaging system at the recent 2019 Radiological Society of North America (RSNA) meeting. The system allows for weight bearing exams. EOS Imaging System the first technology capable of providing full-body, 2-D and 3-D images of pediatric patients in a standing position at a low dose of radiation. The vendor said the scans are much lower dose than computed tomography (CT).

EOS captures bi-planar images with two perpendicular X-ray beams that travel vertically while scanning the patient from head to toe. In less than 20 seconds, the EOS exam produces simultaneous frontal and lateral, low dose images. The two resulting digital images are processed by EOS' proprietary sterEOS software to generate a 3-D model of the patient's spine and/or lower limbs. These detailed images with only 20 seconds of radiation were previously unachievable before EOS technology.

MRI Breast | December 26, 2019

Gillian Newstead, M.D., director of global breast imaging and former professor at the University of Chicago, explains a large breast MRI screening study presented at the 2019 Radiological Society of North America (RSNA) meeting. 

The DENSE Trial Study Group included 40,000 women from the Netherlands who underwent standard mammography. Of these, 8,061 women were identified as having dense breasts and were offered supplemental MRI screening, and about half took advantage of the additional screening. Dense breast tissue which can obscure cancer on conventional mammograms but not on MRI. The MRI cancer-detection rate among the women who actually underwent MRI screening was 16.5 per 1,000 screenings.

The use of supplemental magnetic resonance imaging (MRI) screening in women with extremely dense breast tissue and normal results on mammography resulted in the diagnosis of significantly fewer interval cancers than mammography alone during a two-year screening period. The results were published in the Nov.  28, 2019, issue of The New England Journal of Medicine and presented earlier at the European Congress of Radiology (ECR) 2019.

Computed Tomography (CT) | December 26, 2019

Kevin Little, Ph.D., assistant professor and medical physicist, Department of Radiology, at The Ohio State University, explains how hospitals can better manage their computed tomography (CT) imaging protocols across their fleet of CT scanners from various vendors. He moderated a session on this topic at the 2019 Radiological Society of North America (RSNA) meeting.

He stressed the importance of CT protocol management to an imaging practice and showed examples of tools that can be used to develop consistent protocols across multiple systems. Little said it is important to develop awareness of the Management of Acquisition Profiles (MAP) IHE profile and features that should be requested from CT scanner vendors.

CT protocols, which include all clinical and technical parameters for a given study, are the starting point for achieving high-quality images with reasonable radiation and contrast doses. An imaging practice that desires to follow the "as low as reasonably achievable” (ALARA) principle and produce high-quality images should have standardized protocols across their enterprise. Accreditation standards require a periodic review of all scanner protocols. However, variations among vendors, models, and clinical indications mean that managing and optimizing dozens of parameters for each protocol on every scanner in a health system is challenging. Even when variations between systems are limited, managing protocol names and parameters across multiple systems can be difficult. The purpose of this symposium is to identify tools and techniques that may be used to manage protocols across multiple systems and to provide a framework for protocol optimization.

Magnetic Resonance Imaging (MRI) | December 20, 2019

James Carr, M.D., chair of the Department of Radiology, Northwestern University, and incoming 2020 President of the Society of Cardiac Magnetic Resonance (SCMR), explains why MRI is an ideal cardiac imaging modality, at the 2019 Radiological Society of North America (RSNA) meeting.

Heart MRI offers advantages over computed tomography (CT) and echocardiography because of its excellent soft tissue delineation and its ability to offer information beyond anatomical imaging, such as perfusion, morphology and metabolism. MRI can be technically challenging and the exams requiring a long time, but recent advances have helped cur cardiac imaging times down significantly. Automation and artificial intelligence (AI) also is making post-processing and quantification mush faster, brining it closer to the time it takes to scan and post-process CT imaging.
 
Northwestern is was one of the early adopters of cardiovascular MRI. Carr said heart MRI was not common in regular clinical use until the past decade at some luminary centers. In 2005, Carr was given the opportunity to develop a clinical cardiac MRI program at Northwestern.
 
He said MRI scanners have improved, and now much faster than a decade ago. They are also more optimized for cardiac imaging. While heart MRI is well known in large hospital centers, Carr said it still needs to develop and expand to community hospitals and rural hospitals outside major population centers. 

Artificial intelligence is playing a significant role in cardiac MRI automation of speeding workflow and quantification. Carr said these technologies will become mainstream in the next few years. AI also will play an increasing role in risk prediction based on new image analysis algorithms in development.

Radiation Dose Management | December 19, 2019

Mahadevappa Mahesh, Ph.D., chief of medical physicist and professor of radiology and medical physics, Johns Hopkins University, Baltimore, treasurer of the American Association of Physicists in Medicine (AAPM),a board member of the American College of Radiology (ACR), presented a late-breaking study on how medical imaging radiation dose has started to drop over the past decade. He is the co-chair of the National Council on Radiation Protection and Measures Report (NCRP), and presented the most recent NCRP data analysis at the 2019 Radiological Society of North America (RSNA) meeting.

The new NCRP 184 report covers the period between 2006 and 2016, the period of the most current CMS data. It shows a decrease of about 20 percent in the radiation dose the U.S. population receives from medical imaging, compared to the NCRP 160 that covered the period of up to 2006.

Key findings of the study include:

   • CT dose dropped about 6 percent, despite a 20 percent increase CT scans since 2006;

   • Drop of more than 50 percent for nuclear imaging scans, mainly due to fewer procedures being performed;

   • A 15-20 percent decrease across X-ray imaging modalities.

Mahesh says this shows the impact of using "as low as reasonably achievable" (ALARA) principals, new dose guidelines outlined jointly by numerous medical societies, and dose reduction initiatives like Image Wisely, Image Gently, and the American College of Radiology (ACR) Dose Index Registry.

He said there was growing concern a decade ago when the last council report was published, which showed a steep increase in radiation dose. This was mainly due to a rapid increase in the use of computed tomography (CT) and other types of X-ray based and nuclear radiotracer medical imaging. This prompted the ACR to create the Image Wisely program and push for the use of more thoughtful imaging doses based on patient size, using the "as low as reasonably achievable” (ALARA) principle. While CT dose was lowered, he said the biggest decline over all was in nuclear imaging.
