Utilization rates of noninvasive diagnostic imaging procedures for Medicare population vary regionally

The utilization rates of noninvasive diagnostic imaging procedures such as computed tomography scans, magnetic resonance imaging, and positron emission tomography 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.

Dual-energy CT helps diagnose gout reliably in acute, emergency settings

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. 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 it can better characterize tissue composition better than conventional CT.

Imaging tests used in diagnosis of possible PE vary: Study

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).

QUANTEC review: Updated recommendations for safe irradiation of 16 organs

The Quantitative Analysis of Normal Tissue Effects in the Clinic (QUANTEC) review has been published in the International Journal of Radiation Oncology*Biology*Physics, the official journal of the American Society for Radiation Oncology (ASTRO) to update recommendations for the safe irradiation of 16 organs. For each organ, the relationship between dose/volume and clinical outcome is reviewed. These reviews replace initial recommendations published in 1991.

Combination of gemcitabine and cisplatin limits the progression of endometrial cancer: Study

Researchers from The University of Texas M. D. Anderson Cancer Center report that in a small study of women with advanced or recurrent endometrial cancer, gemcitabine and cisplatin, when used in combination, produced a response rate in fifty percent of patients.

Cryotherapy may become the future treatment for cancer

Cryotherapy, an interventional radiology treatment to freeze cancer tumors, may become the treatment of the future for cancer that has metastasized in soft tissues (such as ovarian cancer) and in bone tumors.

Radiofrequency ablation helps prolong life of colorectal cancer patients

Approximately half of Americans living with colorectal cancer will develop liver metastases at some point during the course of their disease. Radiofrequency ablation, a minimally invasive treatment that applies heat directly in the tumor causing cancer cell death with minimal associated injury to the surrounding healthy liver, contributes to prolongation of their life by nearly three years, note researchers at the Society of Interventional Radiology's 35th Annual Scientific Meeting in Tampa, Fla.

New clinical guidelines: Early diagnosis and treatment of TAD can save lives

When actor John Ritter died suddenly in 2003 from a tear in his thoracic aorta-the large artery that carries blood from the heart to the rest of the body-that tragedy brought attention to a rare but deadly condition that takes the lives of an estimated 10,000 Americans each year.

Lantheus Medical Imaging announces preliminary data on flurpiridaz F 18 PET MPI agent

Lantheus Medical Imaging, Inc., a worldwide leader in diagnostic imaging, today announced preliminary data on flurpiridaz F 18 (formerly known as BMS747158), its novel compound in development as a Positron Emission Tomography (PET) myocardial perfusion imaging (MPI) agent. The study of nine patients compared rest-stress flurpiridaz F 18 PET MPI, with rest-stress technetium-99m (Tc-99m) labeled single photon emission computed tomography (SPECT) for the detection and evaluation of coronary artery disease (CAD).

Angioplasty: Complexity of heart disease, gender and body size influence cumulative radiation skin dose

Body size, gender and the complexity of heart disease significantly influence how much cumulative radiation skin dose that patients receive during percutaneous coronary intervention (PCI) therapy, also known as angioplasty, according to a new Mayo Clinic study. The study was undertaken as a quality control initiative to reduce the potential radiation risks of cancer to patients and PCI operators.

Vitamin D supplements might do more harm than good for African-American patients

Vitamin D is quickly becoming the "go-to" remedy for treating a wide range of illnesses, from osteoporosis to atherosclerosis. However, new evidence from a Wake Forest University School of Medicine study suggests that supplementing vitamin D in those with low levels may have different effects based on patient race and, in black individuals, the supplement could actually do harm.
