AI detects early signs of osteoarthritis from X-ray images

Increased ability to catch osteoarthritis early from X-ray images alone could help treat symptoms and prevent costly MRI examinations.

Urinary stones in the ED: What will it take for ultrasound to gain ground on costly, radiative CT?

Professional consensus supports the use of ultrasound for initial imaging evaluation of patients presenting in the ED with suspected urinary stone disease (USD). However, as of 2018, only 2% of these patients received ultrasound while some 59% had CT.

SPECT technique might measure absorbed tissue dose from radiation therapy

Washington University is using a novel low-count quantitative SPECT technique to measure the concentration of alpha particle radiopharmaceutical therapy activity in the tumor and in radio-sensitive organs.
