Byline: Deborah R. Dakins I recently completed a task that we expect will lead to a more refined search engine for the Diagnostic Imaging Web site and those of our [...]

Byline: H.A. Abella Radiologists face a choice between relinquishing control of ultrasound for good or reclaiming a modality that could thrive in their hands through the next decade. An indication [...]

Byline: C.P. Kaiser In an attempt to stay current with the explosive interest in molecular imaging, the Society of Nuclear Medicine has shed its full name in favor of its [...]

Byline: C.P. Kaiser Dr. Britton Chance is one of the most inventive people in biomedical imaging. But don't expect him to dwell on his past accomplishments. The 93-year-old emeritus professor [...]

Byline: Kathleen Wong Why patients with the same disease can have different fates has stymied physicians for centuries. Diet, genetics, and environment play a role, but more subtle factors are [...]

Byline: C.P. Kaiser When we at Diagnostic Imaging chart trends in radiology, we tend to call on luminaries and thought leaders. But much can be gained from investigating the other [...]

Siemens Medical Solutions has unveiled an investigational data processing technique that may someday eliminate the need for ECG gating during cardiac MRI. Self-gated cardiac MRI freezes heart motion, using data [...]

Real-time MRI has contributed to the early success of an intra-arterial catheter system that transplants stem cells into the myocardium. A multicenter team led by Dr. Casten Rickers of the [...]

Byline: Greg Freiherr Film has been derided as old technology, an out-of-date answer to questions that demand a digital solution. But film today is anything but static. It is a [...]

Byline: R. Edward Hendrick, Ph.D., and Judith A. Wolfman, M.D. In screen-film mammography (SFM), film is the medium for recording, displaying, and storing the x-ray image of the breast. Full-field [...]

Byline: David A. Dowe, M.D., David B. Handel, M.D., and Michael S. Katz, M.D. Coronary artery disease is the most prevalent disease in the U.S. and Europe.1 Every year, 150,000 [...]

Byline: Merlina Trevino Although MRI is sensitive in the diagnosis of breast cancer, it is only moderately specific for that application. Ultrasound techniques provide a good way for imagers to [...]

Children as young as five use the same brain areas for reading as adults do, according to George Washington University researchers. Investigators assessed 16 normal children, aged five to seven, [...]

Byline: Merlina Trevino Both MRI and CT can reliably detect degenerative changes in arthritic joints and document responses to therapy for rheumatoid arthritis, according to studies presented at the 2002 [...]

Byline: Merlina Trevino MR spectroscopy can provide another weapon in the breast cancer detection arsenal. Although the technique is still in development, several advantages recommend it as an adjunct to [...]

Adding gating to thallium-201 SPECT imaging can improve its sensitivity for detecting individual coronary artery stenoses, especially in patients with multivessel disease, researchers in India have found. Nuclear medicine and [...]

Byline: C.P. Kaiser Women with scoliosis who as young girls routinely received multiple x-rays of the spine in the early to mid-20th century were found to have a significantly higher [...]

The symptoms associated with cerebrovascular plaque appear to be more closely tied to plaque composition than to the degree of stenosis, according to a study conducted at West Virginia University [...]

Byline: Harold Abella Despite promising prospects for brain imaging, carbon-11-labeled methionine (Met) for PET faces a major limitation: its short half-life. Using a PET/CT scanner with faster crystals, however, can [...]

Super paramagnetic iron oxide-enhanced MRI may be better than dynamic spiral CT for detecting hypervascular hepatocellular carcinoma, according to a Japanese study. An investigative team at Osaka University compared the [...]

Byline: Douglas Page and Merlina Trevino Clinical conferences and multidisciplinary medical rounds carried out in hospital conference rooms rely on the presentation of images, charts, and videotapes. Like operating rooms, [...]

Byline: Harold Abella Infertile women are often asked to undergo sonography and conventional hysterosalpingography to assess the fallopian tubes. But a new MR technique could replace both, according to researchers [...]

Byline: Harold Abella It's quick, safe, and relatively painless, and if interventional radiologists want to own it, they'd better step up quickly: Endovenous laser treatment of varicose veins is poised [...]

Although radiologists have prospered in the past 12 years, cardiologists have carved out a huge chunk of medical imaging for themselves, according to the American College of Radiology. Radiology's share [...]

Reviewed by Carmen Puliafito, MD Miami--Advances in retinal imaging during the last 10 years have expanded the understanding of the pathogenesis of macular diseases, refined and facilitated earlier diagnoses, and [...]
