Carestream Demos New Digital Breast Tomosynthesis Capabilities

Enhancements help decrease reading time, need for additional exams

October 10, 2014 —  Carestream will show enhancements to its digital breast tomosynthesis (DBT) module including a slabbing tool, improved workflow capabilities and the display of DICOM-compliant 2-D synthetic views (which are generated from the 3-D dataset) at the 2014 Radiological Society of North America (RSNA) conference. The latest DBT module is currently available.

The new slabbing tool combines slices of a DBT series, while allowing the user to choose different rendition modes and slab thicknesses. In scientific studies, radiologists have reported that this capability can help visualize calcifications and decrease reading time. The generation of 2-D synthetic views is an alternate approach to acquiring conventional 2-D mammography views, which can help reduce the radiation dosage a patient is exposed to while allowing full advantage of the benefits of digital breast tomosynthesis.
 
One study that documents the effects of setting the slab thickness of volumes to 2 mm found that visibility of micro-calcifications improved—and there was no significant effect on mass visibility. Radiologists were presented with 20 sets of images containing 16 tumor masses and eight micro-calcification clusters. They ranked 2 mm slabbed sets relative to standard 1 mm slices. The results indicate that it is possible to review DBT volumes with 2 millimeter slabs without compromising image quality.
 
In another study published by SPIE DBT slices were combined and merged into 2 mm slabs. Sets of slabs were created from 35 clinical DBT volumes with malignant or benign findings and from 50 DBT volumes drawn from screening sets without any prior review. There was no significant decrease in reading time on clinical cases, but data for screening images suggests that increasing slab thickness can reduce the time radiologists spend studying normal images by 20 percent.
 
“In my personal experience, DBT tools enable me to detect small lesions that I did not detect on other breast imaging exams and it also decreased the need to recall patients for additional testing,” said Harmindar Gill, medical director, M.D., Premier Women’s Radiology, who uses Carestream’s DBT tools on a Carestream Vue Mammo Workstation.
 
Carestream’s DBT module adds advanced workflow capabilities and specialized tools that can optimize the reading of digital breast tomosynthesis exams at the same time as other procedures. Carestream’s Vue Mammo workstation and PACS allows reading of traditional mammograms, breast ultrasound, breast MRI, DBT or general radiography exams from a single desktop.
?Healthcare providers worldwide use Carestream’s Vue PACS and mammography reading tools for reading of routine screening mammograms as well as diagnostic mammography exams.
 
“Carestream’s Vue PACS is an important tool in our countrywide breast cancer screening program in Kuwait. The PACS provides industry-leading features that help enhance detection of breast cancer and allow us to follow up with our patients, which is extremely important in analyzing data as an initial phase in our program,” said Dr. Hanaa Al Khawari, Consultant Radiologist (FRCR, FFR, RCSI) and Chairperson, Radiology Department, Infectious Disease Hospital. Al Khawari is the head of Kuwait’s National Mammography Screening Program.
