Cystic lesions of the pancreas tend to be a phenomenon of aging. By and large, these lesions are benign, but sorting out the small number that have potential for malignancy is important.
Persistent ground-glass nodules in the lungs are worth a closer look, as they are highly associated with malignancy. Dr. Anne Leung offered an overview of how these lesions present on CT imaging at the 2008 Stanford International Symposium on Multidetector-Row CT in Las Vegas.
A comprehensive CT evaluation of the abdomen requires analysis of the mesenteric vasculature above and beyond the axial plane, according to Dr. Elliot Fishman, director of diagnostic radiology and body CT at Johns Hopkins University and Hospital.
A trip through the MR scanner can wreak havoc with implantable cardiac devices such as pacemakers and defibrillators. But this kind of interference may not be limited to MR imaging, according to Cynthia McCollough, Ph.D.
Philips Healthcare is stepping up efforts to deliver its ultra-premium Brilliance iCT to sites around the world. Jeffrey Studenka, Philips’ senior director for field marketing, told Diagnostic Imaging at the Stanford MDCT conference that the company now expects to have 50 of the 256-slice units installed by the end of 2008. This is about four times as many as company execs were predicting when they unveiled the iCT at RSNA 2007.
Plans are on track for Toshiba America Medical Systems to begin routine shipments by summer’s end of its AquilionOne, featuring the industry’s only wide area detector, spanning 320 detector rows.
CT multitasks in the lungs, serving as a tool for cancer screening, disease diagnosis, lesion characterization, and lung cancer treatment response. In a talk at the 2008 Stanford International Symposium on Multidetector-Row CT in Las Vegas, Michael McNitt-Gray, Ph.D., posited that CT can be used more effectively to assess treatment response in lung cancer patients, but clinicians must look beyond current response parameters.
Logistical and reimbursement limitations dictate that most CT exams be performed on an outpatient basis, making it difficult to manage contrast-related reactions, especially in patients with renal insufficiency. Oral hydration may be as effective as intravenous fluids for preventing contrast-induced nephropathy in some instances, but further study is needed.
