CT Scan Improves Accurate, Timely Diagnosis for Abdominal Issues in ED
January 25th 2011After learning of the CT scan outcomes, physicians changed their diagnoses for 49 percent of patients, and changed management plans for 42 percent, according to a recent study. Doctors decreased the number of those who were initially going to be kept for observation by 44 percent, while 20 percent of patients who were to be admitted were sent home instead.
Featured Search - Perfusion CT Predicts Feared Consequences of tPA-Treated Stroke
January 19th 2011A small study reveals that perfusion CT findings of blood-brain barrier permeability above a specified volume at the time of admission in patients over the age of 65 treated with tPA can predict two “feared complications”-symptomatic hemorrhagic transformation and malignant edema-with 100 percent sensitivity and specificity.

Taste of oral contrast agent affects patient compliance, radiology experience
November 11th 2010Taste matters when it comes to oral contrast agents, and may affect patient compliance, according to a new study. Patients preferred diluted oral contrast agent iohexol (GE Healthcare’s Omnipaque) to diluted diatrizoate sodium (Mallinckrodt’s Gastroview) when undergoing abdominopelvic CT scanning.
CT colonography not threatened by DNA-based cancer detection tests, experts say
October 29th 2010Two new DNA-based tests could noninvasively detect colon cancer, but it is unlikely they will replace CT colonography, according to experts. If anything, the tests could replace the fecal occult blood test currently in use.
UCLA wins renewal of $14 million grant to find medical countermeasures to radiological attacks

NYU plans first annual Dual-Energy CT Symposium
September 14th 2010NYU will hold its first annual Dual-Energy CT Symposium Oct. 9-10 in New York City. The program is designed for radiologists who have or are considering acquiring a dual-energy scanner, research scientists who are looking to understand current uses of dual-energy CT to stimulate development of translational research projects, and technologists who need a basis in dual-energy terminology and concepts.
Citing clinical evidence, coalition urges U.S. panel to approve CT colonography for screening
