Study correlates CTA to angiography, myocardial perfusion SPECT
By Eric Barnes
An ambitious effort to compare the results of coronary CT angiography (CTA), catheter angiography, and myocardial perfusion SPECT imaging yielded good overall agreement in patients with known or suspected heart disease. The researchers, from the Medical University of South Carolina in Charleston, believe CT could potentially replace the other modalities in patients with known or suspected coronary artery disease.

Dual-source coronary CTA detects reduction in lumen diameter
By Paula Moyer
Even in patients with high heart rates, dual-source coronary CT angiography (CTA) provides accurate detection of significant lesions, according to a preliminary study by Dutch investigators. One reason for dual-source CTA's success is technical advancements in the equipment, said the group from Erasmus Medical Center in Rotterdam, Netherlands.

Big Japanese study finds benefit in CT lung screening
By Eric Barnes
SAN FRANCISCO - A lung cancer screening study of nearly 20,000 subjects in Japan found smaller tumors and improved survival rates with CT. Another study, from Oklahoma City, confirmed that CT-detected lung nodules that were stable over two years' time would remain benign.

CT enterography answers range of small-bowel questions
By Eric Barnes
Some radiologists do their best to avoid CT enterography, but they're missing out on a wide range of diagnoses that alternative exams can't provide. Dr. Patrick Rogalla of Charité Hospital in Berlin offers advice for maximizing the value of CT enterography exams for indications ranging from tumor search to inflammatory bowel disease.

Coronary MR protocol picks veins favorable for resynchronization therapy
By Shalmali Pal
BERLIN - One-third of cardiac resynchronization therapy procedures in patients with congestive heart failure (CHF) experience hemodynamic failure, while another 12% are marred by implantation failure. MR coronary vein imaging holds promise for preprocedural assessment of the veins in CHF patients, according to a presentation Monday at the International Society for Magnetic Resonance in Medicine (ISMRM) meeting.

Presurgical fMRI for tumor resection: Are we there yet?
By Shalmali Pal
BERLIN - In theory, functional MRI offers the ultimate noninvasive, presurgical management tool for brain tumor resection. In practice, fMRI techniques have a way to go before they can be as accurate as intraoperative cortical stimulation (ICS), according to Dr. Stefan Sunaert, Ph.D., from the University Hospital of the Catholic University of Leuven in Belgium. Sunaert discussed some of the strengths and weaknesses of fMRI for brain tumor mapping in a talk Sunday at the International Society for Magnetic Resonance in Medicine (ISMRM) meeting.

Two-segment CTA reconstruction aids images, not accuracy
By Eric Barnes
For patients with faster heart rates, the use of two-segment reconstruction improves image quality at 64-slice coronary CT angiography (CTA), according to a study from Germany. Among all patients, however, accuracy was not improved using two-segment when compared to single-segment reconstruction.
