MDCT urography shows potential for detecting bladder cancer without surgery

MDCT urography is a promising technique for detecting bladder tumors both with and without contrast material, helping patients avoid an invasive test, according to a new study by researchers from the University of Michigan Health System in Ann Arbor, MI.

Low radiation dose still means successful interventional procedures

Radiation dose can be reduced by as much as 88 percent for common interventional radiology procedures and still be safe and effective, a new study shows.

African American men have fewer, less severe coronary obstructions than white males

While African American men are more likely to die from cardiovascular disease, they paradoxically have fewer cases of coronary obstruction than clinically similar white men, according to a new national study led by a Medical College of Wisconsin researcher.

Virtual reality simulation technology improves carotid angiography skills

Cardiologists can learn to perform risky catheter procedures such as carotid angiography on a virtual patient simulator, rather than on real patients, according to a new study in the May 2, 2006, issue of the Journal of the American College of Cardiology.

New technique reduces radiation exposure by 60 percent in abdominal CT of children

By lowering the tube current to account for both the weight and body symmetry of a child, an abdominal CT radiation dose can be reduced by 60% without compromising the image quality, says a new study by researchers from the Children's Hospital of Philadelphia in Pennsylvania.

CT colonography even safer than previously thought

The safety profile for CT colonography (CTC) is extremely favorable, particularly for the purposes of screening patients with no symptoms and when distending the colon using an automated carbon dioxide technique, a finding that goes against the higher complication rates for CTC reported by other groups, according to a new study.

Percutaneous image-guided biopsy of renal masses is safe and accurate

For the study, the researchers reviewed 153 kidney biopsies in 126 patients. The researchers found that more than 60% of patients had a change in their treatment--whether surgery, tumor ablation, chemotherapy or radiation--due to biopsy results, and that as many as 75 unnecessary kidney removals were potentially avoided.

Accuracy of PET-CT for detecting recurrent ovarian cancer is high

The accuracy of PET-CT for detecting recurrent ovarian cancer is high, more accurate even than either CT or PET alone, says a new study by researchers from Massachusetts General Hospital in Boston.

Coronal reformatted images speed radiologist's body CT readings

Coronal multiplanar reformatted images can replace conventionally used axial images for interpretation in the MDCT evaluation of the GI tract, improving the speed and accuracy of diagnosis

New radiation protection technique significantly reduces physician radiation exposure during coronary angiography

Using the new device, physicians monitor patients' angiograms and control exam table movement from behind a lead plastic shield. A newly developed extension bar allows the physician to remain safely behind the shield and still retain table control for panning, according to Martin Magram, MD, developer of the new technique and assistant professor in the department of diagnostic radiology.

CT angiography is highly accurate in detecting high-grade artery stenosis

MD-CTA (64-slice CT angiography) is highly accurate in detecting and grading extracranial internal carotid artery (ICA) stenoses in which the artery is closed between 70-90% when compared to color-coded Doppler sonography, power Doppler and B-flow ultrasound

Ultrasound-guided, intra-tendonous injection of a dextrose solution effective in treating chronic tendonoses in the leg

Ultrasound-guided, intra-tendonous injection of a dextrose solution is a very effective treatment for certain chronic tendonoses in the leg, reported radiologists from the department of radiology at St. Paul's Hospital and the Department of Family Practice at the University of British Columbia both in Vancouver, BC.

Research into toxins points to development of better medicines

Researchers have combined magnetic resonance spectroscopy with special protein synthesis procedures to uncover how potassium channels and toxins combine and change in structure. This work could make it possible to develop medications for high blood pressure and many other diseases connected to potassium channel failure .
