A medical imaging technique called dual-energy computed tomography (CT) is an effective and reliable way to diagnose gout in the acute, emergency setting, according to a study published in the April issue of the American Journal of Roentgenology (www.ajronline.org). Dual-energy CT is an advanced medical imaging technique that can detect vessels and bones and display them in clear contrast to one another. It enables physicians to diagnose many patients' conditions faster and more accurately as...

Reduced or no "padding" during ECG-triggered coronary CT angiography (CTA) results in a substantial reduction in radiation dose without affecting image quality and interpretability, according to a study in the April issue of the American Journal of Roentgenology (www.ajronline.org). ECG-triggered coronary CTA is a common, minimally invasive procedure that is used to evaluate blockages in the coronary arteries. "During ECG-triggered coronary CTA, there is a mandatory minimum time that the...

The utilization rates of noninvasive diagnostic imaging procedures such as computed tomography (CT) scans, magnetic resonance imaging (MRI), and positron emission tomography (PET) for the Medicare population vary substantially from region to region, with Atlanta, GA, having the highest utilization rate and Seattle, WA, having the lowest, according to a study in the April issue of the American Journal of Roentgenology (www.ajronline.org). "Underlying regional variation in imaging utilization...

Any patient with a breast lesion classified as a radial scar classified at percutaneous biopsy should undergo a surgical excision to rule out an underlying malignancy, according to a study published in the April issue of the American Journal of Roentgenology (www.ajronline.org). "Radial scars are complex breast lesions that are classified as benign," said Anna Linda, MD, lead author of the study. "However up to 40 percent of them are associated with an underlying malignancy," said Linda. The...

The imaging tests used in the diagnosis of possible pulmonary embolism (PE) vary by physician specialty and geographic region, which suggests that some of this imaging may be inappropriate, according to a study in the April issue of the American Journal of Roentgenology (www.ajronline.org). PE, the formation of a blood clot in the lung, is the third-leading cardiovascular cause of death. As such, it requires prompt diagnosis and treatment. The most common imaging tests used in the diagnosis...

Radiographs (standard X-rays) are often inconclusive in the detection of hip and pelvic fractures in the emergency department, according to a study in the April issue of the American Journal of Roentgenology (www.ajronline.org). "The diagnosis of traumatic fracture most often begins and ends with X-rays of the hip, pelvis, or both," said Charles Spritzer, MD, lead author of the study. "In some cases though, the exclusion of a traumatic fracture is difficult," said Spritzer. The study,...

On-call radiology residents generally provide accurate preliminary interpretation of emergency neuroradiology CT scans after hours when attending neuroradiologist unavailable, according to results of a large study performed at a level I trauma center published in the December issue of the Journal of the American College of Radiology (JACR). The accuracy of image interpretation is the most essential element of diagnostic radiology. In most training programs, radiology residents provide...

Researchers have found recent evidence that shows the growth of external, off-hours teleradiology services (EOTSs) has slowed in recent years, despite a significant increase in the number of radiology practices using those services between 2003 and 2007, according to a study in the November issue of the American Journal of Roentgenology. The data collected showed that the number of radiology practices using EOTSs increased from 15 percent to 44 percent between 2003 and 2007. Patterns of use...

Iodinated and Gadolinium based contrast agents, frequently used during computed tomography (CT) and MRI scans to aid in the imaging process, are associated with a very low rate of adverse effects, according to a large cohort study published in the October issue of the American Journal of Roentgenology (AJR). The study, performed at the Mayo Clinic in Rochester, MN, included a total of 456,930 contrast doses administered. "Only 522 cases of adverse effects were identified," said Christopher H....

The National Academy of Sciences (NAS) today released a report that indicates that low levels of ionizing radiation may cause harm. The following is a response to the report from Bruce McClennan, MD, president of the American Roentgen Ray Society. "This report suggests that there is a very small risk for the development of cancer in a patient's lifetime when exposed to low-level radiation such as that used in diagnostic radiology procedures," said Bruce McClennan, MD, president of the...
