Two studies define role of molecular imaging, therapy in endocrine carcinoma
By Shalmali Pal
Digestive endocrine tumors would seem to be as intricate as the digestive system itself, so it's no wonder that clinicians are searching for the best imaging modality to diagnose, differentiate, and treat endocrine tumors. Two recent studies looked at how molecular imaging and therapy fared in this disease. A group from Poland evaluated endocrine cancer response to treatment with a radiolabeled somatostatin analogue, while researchers in France tested two molecular imaging techniques in endocrine cancers as a tool for diagnosis and staging.

Ovarian metastasis shows distinct CT features in stomach versus colon cancer
By Shalmali Pal
Most nongenital cancers that spread to the ovaries originate in the gastrointestinal tract. Making the distinction between primary and metastatic ovarian tumors is essential for proper patient care, according to a study in the September issue of the American Journal of Roentgenology.

Study pits CT against MRI for virtual colonoscopy
By Eric Barnes
MR colonography offers the promise of radiation-free colorectal exams, excellent soft-tissue contrast, and contrast agents with a better safety profile. But in a polyp-to-polyp face-off in a phantom study, researchers in Germany found that CT colonography (or virtual colonoscopy) still had a sensitivity edge, especially at normal dose levels.

VC visualization tool combines advanced features
By Eric Barnes
Some of the best ideas developed for virtual colonoscopy over the years are being refined and combined to create an advanced exam tool. Researchers from Japan are building Navi-CAD, a comprehensive VC exam system that combines unfolded views of the colonic mucosa, automated polyp detection, and unobserved region detection.
