The FDA announced Tuesday the launch of an initiative to cut unneeded radiation exposure from three kinds of medical imaging procedures: computed tomography (CT), nuclear medicine studies, and flouroscopy. These three are the biggest contributors to total radiation exposure for Americans and use much higher radiation doses than other imaging procedures, such as standard X-rays, dental X-rays, and mammograms.

While CT, … read more »

Distinguishing between benign and malignant liver tumors using contrast-enhanced ultrasound images (CEUS) takes an experienced eye, Italian researchers say. While CEUS can be helpful in diagnosing liver tumors, interpreting such images can be a challenge, according to the researchers. 

The team’s study, which appears in the current issue of Journal of Ultrasound Medicine, used retrospective data from 286 biopsy-proven liver tumors … read more »

Extranodal spread (ENS) of metastatic disease is important to detect in cancer patients, as it indicates a greater likelihood of cancer recurrence and distant metastasis, and also affects treatment planning. Prior studies have shown similar detection rates for MRI and CT.

A recent study was conducted to determine what criteria are most predictive of extranodal spread ENS using MRI to evaluate … read more »
