Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography, and the nuclear imaging modalities of PET and SPECT.

Head CTs could present an opportunity to screen for osteoporosis
In individuals who have not completed a DEXA scan, head CT conducted for other reasons can offer insight into patients’ frontal bone density, a potential marker of osteoporosis.
Combined, alcohol dependence and depression cause 'severe and extensive' brain connectivity impairment
Alcohol dependence and depression are known to affect the functional connectivity of the brain, but when the two co-occur, connectivity between certain regions is significantly worse, new MRI study shows.
PET is an energy hog, but relatively rare utilization lessens its carbon footprint. MRI and CT have no such ‘out’
Medical imaging machinery uses a lot of power, and the extent to which it quickens the pace of global warming is becoming clearer.
One adverse reaction to a GBCA significantly increases risk of another in the future
The type of gadolinium-based agent administered could also increase the risk of reaction, a new study suggests.
Prostate ablation AI 'contouring assistant' lands FDA clearance
The new module is a machine learning-based segmentation tool that further enhances procedural planning.
