CT falls short in differentiating pheochromocytomas

By Radiology Review

(Radiology Review) Researchers at the Cleveland Clinic Foundation in Ohio recently evaluated the prevalence of incidental and symptomatic pheochromocytomas and their CT imaging characteristics. They found no CT parameters that enabled differentiation of the pheochromocytomas. Results of their study were published in the American Journal of Roentgenology.

Contrast delivery key in coronary CTA

Iodine concentration and flow rate have important effects on diagnosing CT angiography data, including better assessment of mixed plaques and stenoses, according to Dr. Christoph Becker and colleagues from the University of Munich. The group's experiments with different delivery parameters in 64-slice CTA have led to new protocols that deliver contrast media more reliably.

Incidental focal findings on FDG PET/CT need follow-up endoscopy

By N. Shivapriya

Incidental focal colonic FDG uptake on PET/CT justifies performing a colonoscopy to detect malignant and premalignant lesions, French researchers have concluded. In a study of 20 patients with 21 areas of focal colonic uptake on routine PET/CT scans, the researchers found clinically significant lesions in 75% of the patients and 67% of the FDG findings.
