New 7T MRI scanners could increase radiologists' role in treating neurological conditions

7T MRI brain scans can analyze the locus coeruleusan area difficult to visualize on standard scannersof patients with Parkinson’s and progressive supranuclear palsy to identify those most likely to respond to certain treatment strategies.

Large study details new associations between breast cancer risk, breast density and benign breast disease

Providers screening women with dense breasts and benign breast disease should consider individualized mammogram protocols for these patients, authors of the study suggested.

AI mammography, prostate imaging algorithms cleared for market

The FDA has OK’d two subsidiaries of Los Angeles-based RadNet to sell medical AI software—one product for diagnosing breast cancer, the other for streamlining MRI prostate reporting workflows.

New radiohybrid PET imaging agent increases detection of prostate cancer recurrence

For 45% to 47% of patients who were deemed negative after conventional baseline scans, the use of the radiohybrid imaging agent resulted in at least one true positive PET finding

Cardiologist and ASNC president diagnoses the heart of the galaxy based on black hole imaging

The first image of the black hole at the heart of our Milky Way galaxy amazed the scientific community, but left cardiologists with questions about the true cardiac health of the galaxy.

Evidence points to optimal MRI sequence for detecting insufficiency fractures

Because sacral insufficiency fractures do not always show a fracture line, they can be difficult to diagnose or even misdiagnosed as bone metastasis, which could result in additional treatments like radio-chemotherapy.

PET/CT offers 'significant prognostic advantage' to patients newly diagnosed with multiple myeloma

The study, which followed 195 patients recently diagnosed with multiple myeloma (MM), found that a negative PET/CT scan six months after diagnosis and induction therapy was significantly linked with improved survival.
