Diagnostic Imaging roundtable tackles rationales and realities of efforts to rein in imaging use in radiology

Specialists apply complex analyses, innovative technologies to diagnose life-threatening injuries caused by blows to the head

High-temp superconductors, implantable ultrasound, 256-slice CT systems pledge to remake landscape of medical imaging

Correlation between pre- and postcontrast images of knees could influence treatment evaluation

New class of antirheumatic drugs heightens need to identify synovial inflammation and early bone damage

Insurers can set your head to spinning fast

Accurate needle placement requires instrumentationfor good imaging contrast and high spatial resolution

New advances in technology keep older modality in the picture for cost-effective cardiovascular diagnosis.

Ask any radiologist to name the fastest growing sectors of the diagnostic imaging industry, and you may get a variety of answers. Unquestionably, device manufacturers are reaping rewards from emerging imaging techniques, particularly new cardiac applications for CT and MR. And teleradiology companies are proliferating by filling the demand for nighttime and weekend teleradiology coverage.

Differential diagnosis of arthritic joint conditions and degenerative spinal disorders can be far from straightforward. Leading musculoskeletal radiologists at the European Congress of Radiology in Vienna showed how careful evaluation of imaging data can improve diagnostic accuracy.

Researchers have developed a new computer-aided analysis technique to identify early cellular damage in Alzheimer’s disease, according to a study in the October issue of Radiology.

If you use ultrasound to guide steroid and anesthetic injections to treat ankle injuries in high-performance athletes, chances are you do not practice in the U.S.

MRI performed at an unlimited specific absorption rate is safe in patients with some permanent pacemakers or implantable cardioverter/defibrillator (ICD) systems, as long as precautions are taken, according to a study from Israel.

Jeffrey Luci, Ph.D., would be the first to admit he is having a busy year. Having attained a faculty position at Vanderbilt University at the end of his National Institutes of Health research fellowship, the former University of Iowa chemistry grad student is now immersed in preparations for his forthcoming wedding. The list of last-minute details may seem endless, but at least the ring is taken care of, thanks to his $1000 award from the RSNA.

MRI is better than multislice CT for determining if and how far breast cancer has spread into the breast ducts, and it should be used before patients receive breast conserving therapy, according to a study in the August issue of the American Journal of Roentgenology.

Our journal review this month includes a new study using cardiac MRI that finds that unrecognized myocardial infarction is relatively common among the elderly and may become a new class of coronary artery disease. Other studies review cardiac MR safety and multislice CT of stent patency and compare 64-slice CT and gated SPECT for the evaluation of left ventricular function.

MRI performed at an unlimited specific absorption rate is safe in patients with some permanent pacemakers or implantable cardioverter/defibrillator (ICD) systems, as long as precautions are taken, according to a study from Israel.

By pinpointing the motor and language areas of the brain with functional MRI, surgeons can target brain tumors more effectively, while reducing the risk of damaging important cognitive and motor processes, according to a study in the September issue of Radiology.

Imaging may not diagnose actual condition, but it gives researchers insight into drug and genetic mechanisms

Stress echocardiography can accurately predict the onset of cardiovascular disease in patients waiting for kidney transplants.

After 19 years in a minimally conscious state, a man recovered language and motor function.

Diffusion-tensor and fiber tract reconstruction MR imaging can track white matter abnormalities that may affect children’s cognitive skills. University of Texas researchers say the new tool could help monitor brain development in pediatric patients.
