Aunt Minnie (5/18, Yee) reports a new study “found that using digital breast tomosynthesis (DBT) in the diagnostic setting reveals more cancers and produces fewer false positives than 2D digital mammography, suggesting that DBT’s proven advantage for breast screening also carries over into the diagnostic realm.” The article explains that the results “are good news because a lower false-positive rate in the diagnostic setting can lead to improved patient care,” according to presenter Dr. Charmi Vijapura from Massachusetts General Hospital in a talk at the recent American Roentgen Ray Society meeting.
The Radiology Business Journal (5/17, Walter) reports Illinois may “become the 36th state that requires mammography providers to notify patients when it is determined they have dense breast tissue” after the state Senate passed “breast density reporting legislation, HB4392.” The House is currently reviewing an identical bill from the Senate. Illinois State Sen. John Mulroe, a sponsor of the bill, said in a prepared statement, “Over the years of working on legislation to address breast cancer, I have heard the heart-wrenching tales of how this disease has ravaged women and their families. If this legislation can save just one life or start just one conversation between a patient and their doctor, it will be well worth the effort.”
HealthImaging (5/14, Rohman) reports that a study indicates “more than 40 percent of women with dense breasts will choose to forgo supplemental breast MRI after receiving a negative mammography screening.” Investigators “found that reasons for non-participation were “MRI-related inconveniences,” such as claustrophobia or refusing contrast agent, and anxiety about supplemental screenings.” The findings were published in Clinical Radiology.
Aunt Minnie (5/10) reports that the FDA has cleared Faxitron Bioptics’ “VisionCT clinical CT scanner for intraoperative margin assessment of breast biopsies and lumpectomies.” The system involves “a motorized, 360° rotating platform that can acquire up to six high-resolution images per second, reconstructing the specimen in up to 1,024 slices at a standard slice thickness of 100 microns.”
The Radiology Business Journal (5/8, Walter) reports on a study published in Academic Radiology finding “no statistically significant difference” between screening digital breast tomosynthesis (DBT) examinations immediately, or after the patient has left. While “prior research has shown” immediate screening “results in a higher rate of false positives,” the researchers argued “stress related to being called back for additional imaging is reduced in patients given immediate results who receive immediate additional imaging” and “The vast majority of patients prefer immediate results of their screening mammogram” according to the researchers.
