Twenty-nine states pay for some diagnostic VC

Slow and steady is winning the race for virtual colonoscopy. As of this month, 29 states have finalized local coverage decisions at the Medicare Carrier Advisory Committee level authorizing VC reimbursement after incomplete colonoscopy.

Study suggests vasovagal reactions are rare in VC

Vasovagal reactions can result from overstimulation of the vagus nerve, and are a phenomenon best avoided. Emotional trauma and certain medications can produce reactions, as can conventional colonoscopy, according to published studies. Can virtual colonoscopy produce vasovagal reactions as well? Researchers from Italy performed a study to address this question.

Distinct CT perfusion parameters help assess HCC

CHICAGO - Hepatocellular carcinoma (HCC) is characterized by highly vascular tumors that progress rapidly yet quite variably from patient to patient. In a new study, researchers are attempting to determine whether perfusion imaging can be used to assess the prognosis of the individual patient, and perhaps help direct treatment.

CT obviates need for biopsy in pancreatic malignancy

CHICAGO - When typical CT features of pancreatic malignancy are present, there's no need for percutaneous biopsy, according to the results of a five-year study presented Monday at the RSNA meeting. As always, oncologists and patients may be hesitant to stop after imaging alone, but the additional information gleaned from biopsy could help direct patient management if other factors, particularly age, are taken into account.
