34+ min ago   (364+ words) The discovery that would reshape cancer treatment began with a noise complaint.In the early 2000s, Zhen Xu, a PhD student at the University of Michigan, was testing high-frequency sound waves on pig hearts when colleagues complained about the noise from…...

1+ hour, 37+ min ago   (571+ words) For patients diagnosed with small kidney cancers tucked dangerously close to the organ’s blood vessels, urine-collecting system, or neighboring bowel, treatment options have long been fraught with compromise. Surgery risks sacrificing precious kidney function, while conventional heat-based ablation risks burning…...

4+ hour, 7+ min ago   (540+ words) Computed tomography has long been one of medicine’s most powerful windows into the human body, but a fundamental limitation has always lurked beneath its grayscale images. Conventional CT measures how much X-rays are attenuated as they pass through tissue, a…...

11+ hour, 3+ min ago   (811+ words) Every few seconds inside a scanning suite, a quiet race unfolds between two forces that pull a medical image apart. On one side is the patient, whose breathing, heartbeat and small involuntary shifts blur the geometry of each frame....

16+ hour, 27+ min ago   (361+ words) Parotid sialocele is a challenging complication following major salivary gland surgery. Traditional conservative management often fails, while revision surgery carries a high risk of iatrogenic facial nerve injury. This retrospective, single-center case series evaluated the clinical efficacy and safety of…...

13+ hour, 17+ min ago   (55+ words) Medical images are often difficult to read, but few imaging modalities test the limits of human and machine perception quite like functional nuclear medicine. Single-photon emission computed tomography, or SPECT, bone scintigraphy produces whole-body maps of radioactive tracer uptake that…...

14+ hour, 10+ min ago   (573+ words) For children complaining of heel pain, hip stiffness, or aching knees, one of the most difficult questions a pediatric rheumatologist faces is deceptively simple: is this growing pain, sports strain, or the first sign of inflammatory arthritis? A new pilot…...

18+ hour, 47+ min ago   (862+ words) Researchers trained AI on how expert pathologists look for signs of cancer in patient samples, improving the algorithm's effectiveness. Artificial intelligence (AI) algorithms that hunt for cancer may do a better job when they approach the analysis as if they…...
