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.

Altered brain structure may play a role in eating disorders, MRI data suggest
Experts recently uncovered evidence suggesting behaviors such as undereating, binging and purging could be owed to anatomical alterations in parts of the brain.
Standard contrast protocols may be 'overdosing' women with the imaging agent
New research suggests female patients attenuate significantly more contrast media in their vessels and organs compared to men.
Abbreviated MRI protocols present suitable alternatives for liver cancer screening
Ultrasound is routinely used to screen for HCC. However, its utility is limited by numerous factors, including patient body habitus, operator experience and certain liver conditions, all of which contribute to decreases in sensitivity.
Commercially available AI increases breast cancer detection by nearly 20%
Results from the world’s largest prospective artificial intelligence study revealed the system could significantly benefit breast cancer screening programs.
Experts update AUC for amyloid, tau PET imaging for first time in more than a decade
The new appropriate use criteria define 17 specific clinical scenarios, guiding providers on situations when amyloid or tau imaging are and are not appropriate.

PET predicts chemo success in non-small cell lung cancer patients

The predictive value of FDG PET for therapy response has been proven for a range of treatments for non-small cell lung cancer (NSCLC), now including concomitant chemoradiotherapy, which requires careful patient selection due to associated morbidity, according to a study published July 17 in the Journal of Nuclear Medicine.
