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.

Japanese researchers have developed a new a computer-aided diagnosis (CADx) system that’s superior to some other methods, relatively easy to use and capable of differentiating between malignant and benign nodules on lung CT.

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.
