esearchers developed MedVersa, a generalist multimodal AI model trained on tens of millions of medical imaging instances to perform diverse radiology tasks within a single framework. The model matched or exceeded specialist AI systems across several benchmarks and produced radiology reports comparable to human reports in many cases while improving reporting efficiency.

Resection of tumors in the caudate lobe (a deep, hard-to-reach part of the liver) is recognized as one of the most technically challenging procedures in hepatic surgery due to its unique anatomical position and complex vascular relationships.

The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural tissue like electrical wires.

Researchers at the Johns Hopkins Kimmel Cancer Center report that an artificial intelligence (AI)-based liquid biopsy test using genome-wide cell-free DNA (cfDNA) fragmentation patterns and repeat landscapes can detect early liver fibrosis and cirrhosis, and may also reveal signals of broader chronic disease burden.

Just a few days in simulated microgravity can subtly change the way women's blood clots, sparking bigger questions about health monitoring protocols for astronauts who can spend six months or more in orbit, say Simon Fraser University researchers.
