AI competition furthers research on computer-aided detection in breast imaging

For the challenge, eight teams were tasked with developing algorithms capable of achieving high sensitivity for lesion detection on DBT exams.

MRI catches CT in head-to-head lung imaging

When it comes to assessing patients with suspected pulmonary embolism, contrast-enhanced CT pulmonary angiography has no diagnostic edge over a certain free-breathing, unenhanced MRI perfusion protocol.

Mediolateral oblique view from a screening mammogram in a 54-year-old woman shows a small cluster of microcalcifications in the upper outer quadrant of the right breast. The right image shows a detailed spot magnification view of the calcifications. Stereotactic biopsy revealed grade 2 ductal carcinoma in situ (DCIS). RSNA image. Image of breast micro calcifications associated with breast cancer.

Why the way microcalcifications on mammograms are regarded could change

New research suggests that the tissue environment where microcalcifications of the breast are formed could hold clues into how breast cancer progresses.

Focused ultrasound reduces physical symptoms of Parkinson's disease

Given the less invasive nature of focused ultrasound procedures, researchers suggest that it could open the door for disease management options catered to a wider variety of patients.

Bertram Pitt, MD, a professor of medicine emeritus at the University of Michigan School of Medicine, explains the role of sodium–glucose co-transporter-2 (SGLT-2) inhibitors for heart failure (HF). Initially developed to treat diabetes, these drugs have been shown to improve HF outcomes in HF in several large, randomized trials over the past few years, including SOLOIST-WHF, DAPA-HF, EMPEROR-Preserved, and the DELIVER trials. The positive results earned their inclusion in the 2022 AHA/ACC/HFSA Guideline for

What clinical research tells us about sotagliflozin and heart failure

Some SGLT2 inhibitors have been linked to significant improvements in HF outcomes, but what about sotagliflozin? We spoke with Bertram Pitt, MD, to learn more.

Including radiologists in radiotherapy prep bolsters quality of care

Many radiation oncologists are not formerly trained in imaging interpretation, and radiologists’ collaborative participation in care planning can help to catch errors, experts wrote recently.

Expert left 'astounded' by gadolinium discovery

New data out of the University of New Mexico suggest that the imaging agent’s physiologic reach may exceed what was previously believed.

How effective are chest CT severity scores in managing COVID?

While the studies on these systems have proven them to be effective in diagnosing and treating COVID in specific cohorts, the varying settings in which they were used can make it difficult to derive definitive conclusions on their efficacy.
