Adjunctive technique improves sensitivity, specificity
A new method of computer-aided evaluation makes it easier to differentiate between benign and malignant lesions on MR scans, possibly reducing the number of false positives and unnecessary biopsies.
Other findings include:
- Computer-aided detection is no match for a dedicated breast imaging specialist, according to a large comparative study of 5875 consecutive screening mammograms performed at Yale's Breast Imaging Center.
- Breast MR spectroscopy as an adjunct to breast MR may cut the rate of false positives related to the stage of a woman's menstrual cycle.
- In the Digital Mammographic Imaging Screening Trial (DMIST), 40% of the women over 50 had dense breasts, indicating that digital screening could benefit older as well as younger women.
- DMIST researchers plan to investigate why there was a difference between digital and film-based screening and will also perform a cost-effectiveness study for digital imaging.
Seven Takeaways from Meta-Analysis of PSMA Radiotracers for Prostate Cancer Imaging
December 1st 2023In a newly published meta-analysis of 24 studies, researchers noted that the PSMA PET radiotracer 18F PSMA-1007 may provide more benefit than 68Ga Ga-PSMA-11 for primary staging of patients with prostate cancer and detection of local lesion recurrence, but also has drawbacks with higher liver uptake and multiple reports of false positive bone lesions.
Study: Regular Mammography Screening Reduces Breast Cancer Mortality Risk by More than 70 Percent
November 30th 2023Consistent adherence to the five most recent mammography screenings prior to a breast cancer diagnosis reduced breast cancer death risk by 72 percent in comparison to women who did not have the mammography screening, according to new research findings presented at the annual Radiological Society of North America (RSNA) conference.
Chest CT Study Shows Higher Emphysema Risk from Combination of Marijuana and Cigarette Smoking
November 28th 2023People who smoke marijuana and cigarettes have 12 times the risk for centrilobular emphysema than non-smokers, according to new computed tomography (CT) research presented at the annual Radiological Society of North America (RSNA) conference.
