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.

The new Visicoil MR is a helically-wound, flexible linear fiducial marker. The Visicoil MR hollow core design and multiple sizes mitigates the CT artifact often created by traditional gold seeds, offering you clearer visualization of the tissue to aid in faster and more accurate contouring. Visicoil MR's linear flexible design fixates and remains stable in soft tissue, giving you the confidence in accurate marker localization. Visicoil MR is available in some of the smallest needle sizes available for fiducial markers, including 21g and 22g needles. The benefits of smaller needles are improved patient safety and comfort during implantation. The smaller needles may also allow for faster CT sim after implant and ultimately treatment for your patients. The new Visicoil MR with enhanced MRI visibility allows you to see the marker more easily in MRI, both in T1 and T2. This makes for easier and faster MR/CT fusion.

The next generation of ZONE Sonography Technology (ZST) has arrived and its living technology continues to evolve. Leveraging ZONARE’s revolutionary ZST and Mindray’s rich repertoire of workflow and user interface features, the Resona 7 is poised to become the new industry leader in premium ultrasound imaging platforms. The Resona 7 presents crystal clear B-mode imaging capabilities with unrivaled detail resolution and image uniformity across all radiology applications. Ultrasensitive Doppler modes and high-speed digital signal processing permit accurate display of hemodynamic states from skin line to depths up to 40 cm without compromising frame rate. An intuitive, customizable gesture-powered touchscreen enables logical and efficient workflow and enhanced user experience.
At its core, ZST provides unique imaging advances for the Resona 7 such as Advanced Acoustic Acquisition which renders superb imaging by using large zones to acquire up to 90 percent more acoustic data per frame and at speeds of 10 times faster than conventional technology. Dynamic Pixel Focusing creates a perfectly focused image every pixel, every frame, in every patient and in every application. Sound Speed Compensation enables a one button touch that automatically calculates the true speed of sound in a specific soft tissue and recalibrates the imaging system to optimize spatial and contrast resolution.
Finally, ZST provides Total Recall Imaging which is powerful software that allows manipulation of raw acoustic data from archived and cine images (clips) permitting a broad range of post-processing functions. This eliminates the need for repeat scanning which, in turn, aids in increasing patient throughput.
ZST is a constantly evolving software-based “living technology.” It is Mindray’s approach to providing customers with easily upgradeable ultrasound enhancements. These upgrades secure product investment protection by ensuring that ZST systems remain at the cutting-edge of imaging performance excellence throughout the system’s entire life cycle.
In summary, coupling premium imaging with advanced workflow features and user-directed ergonomic design, the Resona 7 advances premium level ultrasound imaging into the next generation.

A post-game roundup by ITN Contributing Editor Greg Freiherr and ITN Editor Dave Fornell on the trends and new tech seen on the show floor at the Radiological Society of North America (RSNA) 2016 meeting.
At RSNA 2016, the key buzzwords were “deep learning,” “machine learning” and “artificial intelligence.” Vendors and major academic centers are developing a wide array of artificial intelligence neural networks to aid radiologists in clinical diagnosis and clinical decision support. In the future, AI may also be able to help train radiologists on both normal and abnormal presentations of various organs and body systems so as to more easily identify related disease states and conditions. The following video offers two examples of how the IBM Watson system examines imaging studies.
The first case seen here demonstrates how Watson can arrive at a differential diagnosis of an aortic dissection by analyzing an abdominal computed tomography (CT) scan. The second case involves the discovery of a fibroadenoma of the breast from Watson’s analysis of a mammogram.
Watson first analyzes the text of the radiology report, identifying and pulling out key words or phrases that may indicate the potential diagnosis. It then examines the CT scan to locate relevant visible anatomic structures such as the heart, aorta and pulmonary artery. Each structure is examined for anomalies, which identifies a possible aortic dissection; the dissection is displayed within the context of the entire 3-D CT scan. Finally, Watson applies its existing clinical knowledge to the findings from the CT scan and the radiology report, establishing pathways to numerous possible conclusions until arriving at the right one.
See examples of real products using AI at RSNA 2017 in the VIDEO "Examples of How Artificial Intelligence Will Improve Medical Imaging." ITN also created an in-depth VIDEO: Technology Report — Artificial Intelligence at RSNA 2017, with interviews with numerous AI vendors.

Gadolinium-based contrast agents have been used for diagnosis and treatment guidance in more than 100 million patients worldwide over the past 25 years. These agents enhance the quality of MR images by altering the magnetic properties of nearby water molecules in the body. By improving the visibility of specific organs, blood vessels or tissues, contrast agents help physicians diagnose and treat a wide variety of medical conditions. On its own, gadolinium can be toxic. Therefore, when used in contrast agents, gadolinium is bonded with a molecule called a chelating agent, which controls the distribution of gadolinium within the body.
