Radiologists Can Dramatically Lower Cardiac CT Radiation Dose in Some Patients
Radiologists can now lower the radiation dose delivered by cardiac CT angiography by 39% in adult patients weighing 185 pounds or less, according to a study performed at the University of Erlangen in Erlangen, Germany. view more (2009-04-06)
MDCT Angiography Helps Lead to Successful Treatment of Patients with Severely Blocked Arteries in the Legs
MDCT angiography leads to accurate recommendations for successful treatment of patients with critical limb ischemia, sometimes allowing the patients to avoid more complicated surgery, according to a study performed at the Medical University of Vienna, Vienna, Austria. view more (2009-06-04)
MDCT angiography for cardiac imaging: Reliable tool, less invasive, fewer complications
A new procedure for the imaging of coronary veins proves to be "less invasive, have less complications, and improves the quality of diagnosis and treatment " for individuals undergoing surgical procedures on the heart and particularly the coronary veins, a recent study found. view more (2005-12-30)
Radiologists find a technique to significantly reduce patient radiation dose during CT angiography
Radiologists have discovered that prospective electrocardiogram (ECG) gating allows them to significantly reduce the patient radiation dose delivered during computed tomography (CT) angiography, a common noninvasive technique used to evaluate vascular disease. view more (2009-09-21)
Catheter angiography may be an unnecessary follow-up to CT angiography
Even in challenging cases, CT angiography (CTA) offers an accurate and rapid diagnosis for blunt trauma victims who may have aortic or great vessel injury negating the need for more invasive procedures. view more (2007-09-21)
Angled gantry technique reduced breast radiation exposure by 50 percent
A novel angled gantry approach to coronary CT angiography reduced radiation exposure to the breast by more than 50%, according to Thomas Jefferson University researchers. view more (2008-12-04)
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)
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)
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)
Extremely low dose CT coronary angiography shows promise in assessing cardiac function
Extremely low dose CT coronary angiography can be used to measure cardiac function and has the potential for use when other commonly used examinations are limited, a preliminary study indicates. view more (2008-04-14)
Researchers Find a Way to Reduce Patient Radiation Dose During Pulmonary CT Angiography
While screening for possible pulmonary emboli using pulmonary CT angiography, a new study shows that radiologists can effectively lower the patient radiation dose by approximately 44% and improve vascular enhancement without deterioration of image quality. view more (2009-07-01)
Coronary CTA costs less than standard of care for triaging women with acute chest pain
Non-invasive coronary CT angiography (CTA) is more cost-effective than current tests for diagnosing women with low risk of a heart attack who come to the emergency room with acute chest pain, according to a recent study conducted by researchers at Harvard University in Cambridge, MA. view more (2008-08-11)
Whole body MDCT just as 'good' as neck MDCT angiography in diagnosing head and neck injuries
Blunt cerebrovascular injuries can be diagnosed using whole body 16 multi-detector CT (MDCT); there's no need for an additional neck MDCT angiography examination. view more (2008-03-31)
Same-day coronary angiography and surgery safe for many patients
Mayo Clinic researchers discovered it is safe -- and much more convenient and less costly -- for many patients to undergo coronary angiography and elective valve surgery on the same day, it is reported in the current issue of Mayo Clinic Proceedings. view more (2007-05-24)
Coronary angiography may improve outcomes for cardiac arrest patients
People who suffer cardiac arrests and then receive coronary angiography are twice as likely to survive without significant brain damage compared with those who don't have the procedure, according to a study by University of Pittsburgh School of Medicine researchers. view more (2009-04-01)
Pulmonary CT angiography identifies disease and injury beyond the pulmonary arteries in children
Computed tomography angiography (CTA) can identify abnormalities and injury beyond the pulmonary arteries, including broken bones and heart disease, according to a study published in the September issue of the American Journal of Roentgenology (AJR) view more (2009-08-19)
Radiation Dose Can Be Reduced For "Triple Rule-Out" Coronary CT Angiography
Physicians can dramatically reduce the radiation dose delivered to patients undergoing coronary CT angiography in a "triple rule-out" protocol by simply using tube current modulation, according to a study performed at Thomas Jefferson University Hospital in Philadelphia, PA. view more (2009-04-06)
What are the risk factors for rebleeding after negative angiography?
Acute non-variceal gastrointestinal bleeding accounts for approximately 20% of emergency room visits and 5% of admissions. view more (2009-09-16)
Preventing Sudden Death: EBCT Scans Trump Angiography at Detecting Killer Heart Defect
Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for detecting a dangerous congenital heart abnormality that could cause sudden death. view more (2005-10-11)
Noninvasive Screening Test May Detect Narrowing in Intracranial Stents According to Study by Rush University Medical Center
Great advances have been made in treating blockages in the arteries of the brain using angioplasty to widen the narrowed artery and a stent to hold the artery open. view more (2009-02-12)
