MRI enhanced with gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid—the scan referred to as “EOB MRI”—is significantly better than contrast-enhanced CT for assessing colorectal liver metastases that disappear after chemotherapy, according to a study published online March 22 in Radiology.

A group of researchers from the University of Wisconsin found patients who underwent endoscopic ultrasound (EUS) had longer times-to-surgery than those who didn’t. Led by resident Ryan Schmocker, MD, the team linked certain geographical areas and institutional factors to a higher likelihood of undergoing EUS, in addition to a baseline increase in utilization nationwide.

Patients and their physicians detect more recurrences of melanoma than routine surveillance imaging does, according to a study published online Feb. 8 in the Journal of the American College of Surgeons.

Danish researchers have found whole body PET/CT augmented by the radiotracer FDG is superior to straight CT as a first-line modality for imaging patients with serious non-specific symptoms and signs of cancer (NSSC). Their study was published online Jan. 12 in the Journal of Nuclear Medicine.

Tweets about lung cancer screening multiplied markedly after the U.S. Preventive Services Task Force released its guidelines on screening with low-dose chest CT (LDCT) in December 2013, according to an analysis published online Jan. 13 in the Journal of Digital Imaging.

Most interval lung cancers missed at NLST screening

A retrospective analysis of National Lung Screening Trial (NLST) exams has shown that most lung cancers that were detected within a year after a negative CT screening exam—some 40 of 44, or 91 percent—were present but overlooked at the screening. 

Watch for PET/CT to grow as an aid to image-guided biopsies of children

PET/CT can add value to cancer staging and follow-up in pediatric patients. In fact, it may come to play an important role in directing image-guided biopsies of children, according to a study published online Dec. 27 in the American Journal of Roentgenology.

CT is effective in staging colon cancer—with minor drawbacks

A retrospective study published in the American Journal of Roentgenology determined that CT is a useful tool for staging colon cancers that have moved beyond the bowel wall. While performance suffers in certain situations, the largely Dutch authors recommend using thin-slice CT to detect cancers.
