Study finds rise in rate of diagnostic imaging in managed care
Use of radiology imaging tests has soared in the past decade with a significant increase in newer technologies, according to a new study that is the first to track imaging patterns in a managed care setting over a substantial time period. view more (2008-11-10)
When Conservative Treatment Fails: Sonographically-Guided Debridement Offers "Non-Surgical" Method for Chronic Tendinosis of the Achilles Tendon
Researchers have found an alternative, "non-surgical" method to treat chronic tendinosis (tendinitis) of the Achilles tendon that fails conservative treatment, according to a study performed at the Feinberg School of Medicine, Northwestern University in Chicago, IL. view more (2009-04-24)
New Computer Algorithm Helps Physicians Determine and Monitor Breast Density: Increased Breast Density is a Strong Predictor of Overall Breast Cancer Risk
A new computerized assessment has been developed that can help physicians objectively assess a patient's breast density and monitor it over time to detect any alarming changes that may suggest cancer, according to a study evaluating this technology that was performed at the University of Maryland School of Medicine, Baltimore, MD. view more (2009-04-24)
New MRI finding sheds light on multiple sclerosis disease progression
Using magnetic resonance (MR) images of the brain, researchers have identified a new abnormality related to disease progression and disability in patients with multiple sclerosis (MS), according to a study published in the August issue of Radiology. view more (2007-08-28)
The first 3 Teslas magnetic resonance imager for research
The University Hospital at the University of Navarra and the Applied Medicine Research Centre (CIMA) of the University has recently acquired a 3 Teslas magnetic resonance imager for joint use, the first for research applications in Spain. view more (2006-10-27)
Imaging technique accurate in aneurysm detection and therapy planning
Multidetector computed tomography (MDCT) angiography is highly accurate in depicting intracranial aneurysms, according to a study published in the August issue of Radiology. In addition, MDCT angiography can be used to quickly determine the possibility of using minimally invasive treatment rather than open surgery. view more (2007-07-31)
Breast cancer is more aggressive in African-American women
African American women are diagnosed with breast cancer at a younger age and have larger tumors and more lymph node involvement than Caucasian women, a Yale School of Medicine researcher reported today. view more (2007-10-30)
New treatment option for ruptured brain aneurysms
Researchers in Finland have identified an effective new treatment option for patients who have suffered a ruptured brain aneurysm, a potentially life-threatening event. Results of the new study on stent-assisted coil embolization were published today in the online edition of Radiology. view more (2009-08-26)
Dartmouth's alternative breast imaging techniques sort abnormal from normal tissue
Dartmouth physicians and engineers have published a paper with results from a five-year project testing three new imaging techniques to examine breast abnormalities, including cancer. view more (2007-06-06)
Freezing kidney cancer: Hot treatment should be new gold standard for destroying small tumors
Freezing kidney tumors-using a safe minimally invasive interventional radiology treatment that kills the cancer 100 percent effectively without surgery-should be the gold standard or first treatment option for all individuals with tumors that are 4 centimeters in size or smaller. And, this treatment-interventional cryoablation-is a viable option... view more... (2009-03-09)
Ultrasound used to predict heart attack risk
Repeat exams using widely available and inexpensive ultrasound imaging could help identify patients at high risk for a heart attack or other adverse cardiovascular events, according to a study published in the September issue of the journal Radiology. view more (2008-08-19)
Smoking seems to increase brain damage in alcoholics
It is already well-known that the brains of long-term alcoholics atrophy and shrink, the study authors say, but the new findings are the first evidence that cigarette smoking might contribute to that atrophy, particularly in grey matter of the parietal and temporal lobes. view more (2005-09-29)
Ultrasound proves safe alternative to biopsy in some breast masses
Researchers have reported that breast masses shown on ultrasound that are diagnosed as "probably benign" can be safely managed with imaging follow-up rather than biopsy, according to a study appearing in the July issue of Radiology. view more (2007-06-26)
A feasible, simple and convenient model for study of rectal carcinoma
The method of building a rabbit rectal VX2 carcinoma model by injecting the cell suspension of VX2 cells into the wall of the rectum guided by X-ray fluoroscopy is feasible. view more (2009-05-13)
Penn researchers examine the effects of meditation on early cognitive impairment
Researchers at the University of Pennsylvania School of Medicine are examining the effectiveness of meditation on early cognitive impairment. view more (2006-07-31)
MR angiography highly accurate in detecting blocked arteries
A novel type of contrast-enhanced magnetic resonance (MR) angiography is highly accurate in identifying blockages in the arteries that carry blood to the brain, according to a study in the February issue of Radiology. view more (2007-01-30)
Johns Hopkins researchers suppress 'hunger hormone'
Johns Hopkins scientists report success in significantly suppressing levels of the "hunger hormone" ghrelin in pigs using a minimally invasive means of chemically vaporizing the main vessel carrying blood to the top section, or fundus, of the stomach. view more (2008-09-16)
MRI rules out acute appendicitis in pregnancy
Magnetic resonance imaging (MRI) can help rule out acute appendicitis in pregnancy when ultrasound findings are inconclusive, according to a study in the March issue of Radiology. view more (2006-02-28)
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)
