UVa Participates in Landmark Breast Cancer Screening Trial
Digital mammography that uses computers to detect breast cancer found significantly (up to 28%) more cancers than screen film mammography in women 50 and younger, premenopausal and perimenopausal women, and women with dense breasts, according to results from one of the largest breast cancer screening studies ever performed. view more (2005-09-21)
New 'seed' therapy helps pinpoint breast tumors with more accuracy
Physicians at UT Southwestern Medical Center are the first in Texas to use a new technique in which a small radioactive pellet, or "seed", is implanted into a mass or suspicious lesion in the breast to pinpoint its exact location for surgical removal. view more (2007-10-11)
CT angiography highly accurate, multicenter trials show
Computed tomography (CT) angiography is as accurate as an invasive angiogram in detecting coronary artery disease, according to the findings of the first two prospective multicenter 64-slice scanner trials presented today at the annual meeting of the Radiological Society of North America (RSNA). view more (2007-11-27)
Majority of Ordering Physicians Lack Knowledge of Radiation Exposure Risks from CT
Ordering physicians have limited knowledge of CT-related radiation exposure and its associated risks, according to a study performed at the Carilion Clinic in Roanoke, VA. view more (2009-04-24)
New MR Sequence Helps Radiologists More Accurately Evaluate Abnormalities of the Uterus and Ovaries
A new MR imaging sequence, T2-weighted BLADE, used to image the female pelvis improves image quality and helps radiologists make a more accurate diagnosis, according to a study performed at the University of Maryland School of Medicine in Baltimore, MD. view more (2009-04-24)
Patient photos spur radiologist empathy and eye for detail
Including a patient's photo with imaging exam results may enable a more meticulous reading from the radiologist interpreting the images, as well as a more personal and empathetic approach, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). view more (2008-12-02)
Lifestyle changes remain important in fighting peripheral arterial disease
Modifying the risk of peripheral arterial disease (or PAD)-with healthy lifestyle changes-remains vital to one's health, note researchers in a recent issue of the Journal of Vascular and Interventional Radiology. view more (2009-10-22)
New approach allows closer look at smoker lungs
Aided by a powerful imaging technique, scientists have discovered they can detect smoking-related lung damage in healthy smokers who otherwise display none of the telltale signs of tobacco use. view more (2006-05-31)
Health groups issue updated colorectal cancer screening guidelines
The American Cancer Society, the American College of Radiology, and the U.S. Multi-Society Task Force on Colorectal Cancer (a group that comprises representatives from the American College of Gastroenterology, American Gastroenterological Association, and American Society for Gastrointestinal Endoscopy) have released the first-ever joint consensus... view more...

Under some conditions this energy-hungry organ is prone to defects in its energy metabolism that contribute to heart disease. view more (2006-08-07)
New Non-Invasive Method In Lung Diagnostics
Magnetic resonance imaging (MRI) as a non-invasive diagnostic method has been evolving into an attractive alternative to methods which are associated with radiation exposure. This development now also starts to manifest itself in lung perfusion imaging. This was reported by Dr. Christian Fink and colleagues of the Radiology Division of the... view more... (2004-06-24)
New Generation of Contrast Agents Provides Hope for Enhanced Brain Tumor Diagnostics
In a pilot study of gadobenate dimeglumine (GD-BOPTA), the new contrast agent has yielded improved diagnostic imaging of brain tumors in magnetic resonance imaging (MRI) compared to standard contrast media. A team of researchers headed by PD Dr. Marco Essig, Division of Radiology of the Deutsches Krebsforschungszentrum (German Cancer Research... view more... (2004-05-03)
PET/CT planning beneficial for head and neck cancer patients
Using a combination of positron emission tomography (PET) and computed tomography for radiation therapy treatment planning in head and neck carcinoma patients provides for excellent, local and regional disease control when compared to CT alone. view more (2008-03-05)
Pregnant women should not ignore breast cancer symptoms
Ultrasound provides a safe and accurate method of detecting breast cancers in pregnant women, as well as assessing response to chemotherapy. view more (2006-03-28)
MRI contrast agent linked to rare disease
New research has shown a possible association between a popular magnetic resonance imaging (MRI) contrast agent and the incidence of a rare disease called nephrogenic systemic fibrosis (NSF) in patients with kidney disease. view more (2007-01-29)
Portable CT increases chance of stroke survival and recovery
New research has found that the availability of a portable eight-slice computed tomography (CT) scanner in an emergency room can significantly increase the number of stroke victims who receive a potentially life-saving treatment. view more (2008-12-02)
'Virtual autopsy' helps identify drowning as cause of death
"Virtual autopsy" performed with multidetector computed tomography (MDCT) can aid forensics teams in determining if a person has drowned, according to a study published in the June issue of Radiology. view more (2007-05-29)
Tiny self-assembling cubes could carry medicine, cell therapy
Johns Hopkins researchers have devised a self-assembling cube-shaped perforated container, no larger than a dust speck, that could serve as a delivery system for medications and cell therapy. view more (2005-12-13)
