VC goes extra innings with AAA screening
By Eric Barnes
Virtual colonoscopy can do double duty by screening for abdominal aortic aneurysm (AAA), according to a study of more than 1,000 individuals. Researchers found that virtual colonoscopy was reliable for detecting AAA or, more commonly, for ruling out the condition.

Hopeful VC symposium attendees set plans
By Eric Barnes
After nearly two decades of promoting a colorectal cancer screening exam they believe is a better test than optical colonoscopy, virtual colonoscopy advocates have no illusions about the difficulties that have impeded their efforts to secure reimbursement for screening. But lately they're more hopeful of a real breakthrough.

PET/MRI tops PET/CT in abdominopelvic lesion conspicuity
By Wayne Forrest
Wednesday, November 28 | 11:50 a.m.-12:00 p.m. | SSK08-09 | Room S504CDPET/MRI with ultrafast gradient-recalled echo and spin-echo sequences is superior to PET/CT for lesion conspicuity, thus potentially improving therapy for patients with abdominopelvic cancer, according to a study by Swiss researchers.

FDG-PET/CT helps assess pancreatic cancer recurrence
By Wayne Forrest
Wednesday, November 28 | 11:30 a.m.-11:40 a.m. | SSK13-07 | Room S505ABFDG-PET/CT has "excellent accuracy" in detecting a recurrence following resection of pancreatic cancer, and maximum standardized uptake values can be used in determining the prognosis of these patients, according to researchers from India.

DOTATATE-PET/CT helps detect pancreatic neuroendocrine tumors
By Wayne Forrest
Monday, November 26 | 11:50 a.m.-12:00 p.m. | SSC13-09 | Room 505ABIn this retrospective study from University of Munich Hospital, researchers found that DOTATATE-PET/CT detects pancreatic neuroendocrine tumors better than MRI.

Microbubble US helps early assessment of liver dysplasia
By Wayne Forrest
Monday, November 26 | 11:30 a.m.-11:40 a.m. | SSC09-07 | Room S504CDIn this presentation, German researchers will discuss their preliminary success with an ultrasound contrast agent -- known as BR55 -- that uses microbubbles targeting vascular endothelial growth factor receptor 2 to assess liver dysplasia.

PET/MRI outshines PET/CT in lesion detection
By Wayne Forrest
Monday, November 26 | 11:00 a.m.-11:10 a.m. | SSC13-04 | Room S505ABPET/MRI showed superior lesion detectability compared to contrast-enhanced PET/CT in this study from King Fahad Specialist Hospital in Dammam, Saudi Arabia. Based on the results, researchers concluded that PET/MRI may be useful for abdominal lesion staging while sparing patients from contrast media.
