COVID-19 boosts cardiovascular event risk

By Kate Madden Yee

COVID-19 is associated not only with acute lung damage but also with rapid growth of plaque in the coronary arteries -- and thus an increased risk of cardiovascular events.

Using AI with mammography can help select women for breast MRI

By Amerigo Allegretto

Using AI with mammography can help select women at high risk of breast cancer for supplemental MRI.

February 4, 2025

Images depict a 55-year-old woman with a family history of breast cancer who underwent combined mammography and MRI screening. (A) Right and (B) left mediolateral oblique and (C) right and (D) left craniocaudal mammograms show a large known cyst in the left breast (arrow in B and D), but were otherwise assessed as being unremarkable. Breast tissue was judged to be extremely dense. (E) Concurrent axial subtraction MRI scan shows a large, diffuse, invasive lobular cancer (circle) in the right breast. The AI system provided a case-based cancer suspicion score of 8 on a scale of 0-10, which would have led to selection for MRI screening using both the score 5 and score 8 thresholds, but not the score 9 threshold.

Ultrafast MRI exam bests standard MRI for classifying breast cancers

By Amerigo Allegretto

An ultrafast MRI-based radiomics exam performs just as well as standard MRI and isn’t dependent on radiologist experience.

January 28, 2025

Ultrafast and standard MRI in a 30-year-old woman with triple-negative invasive ductal carcinoma. (A) Ultrafast MRI taken 16.8 seconds after contrast agent injection. (B) Standard MRI taken 58.8 seconds after contrast agent injection. Both images show an oval-shaped, irregular marginated, rim-enhancing mass in the left outer breast. For 3D tumor segmentation, the entire enhanced tumor margins were drawn from top to bottom of each tumor in axial views of U2 phase postcontrast ultrafast MRI and the initial phase postcontrast standard MRI. Among the 14 ultrafast images, U1 is the first phase in which the signal intensity of the hotspot region of interest of the tumor is 10% higher than the average signal intensity of unenhanced images. U2 is the immediate next phase of U1 and the well-established tumor enhancement time.
