Cataract surgery does not appear associated with worsening of age-related macular degeneration
Age-related macular degeneration does not appear to progress at a higher rate among individuals who have had surgery to treat cataract, contrary to previous reports that treating one cause of vision loss worsens the other. view more (2009-11-10)
Lung scintigraphy more reliable than CTA in excluding pulmonary embolism in pregnant patients
A medical imaging procedure known as lung scintigraphy may be more reliable than pulmonary CT angiography (CTA) for identifying or excluding pulmonary embolism (PE) in pregnant patients. view more (2009-10-21)
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)
Comprehensive cardiac CT scan may give clearer picture of significant heart disease
A team of researchers led by Massachusetts General Hospital (MGH) radiologists has developed a computed-tomography-based protocol that identifies both narrowing of coronary arteries and areas of myocardial ischemia - restricted blood flow to heart muscle tissue - giving a better indication of clinically significant coronary artery disease. view more (2009-09-16)
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)
Imaging features of intraductal papillary mucinous neoplasms of the pancreas
The intraductal papillary mucinous neoplasms (IPMN) can evolve through all biological stages, from slight dysplasia to carcinoma. view more (2009-09-16)
New strategies for reperfusion therapy
A new trial has begun in order to ascertain once and for all whether the best strategy for patients who cannot receive P-PCI is early fibrinolysis, together with mandated angiography. view more (2009-08-31)
Surgical treatment a rare complication of duodenal diverticulum
Most of the duodenal diverticula are diagnosed incidentally and asymptomatic, 12% to 27 % at endoscopy. Only 5% to 10% of patients with duodenal diverticula suffer from clinical symptoms. view more (2009-08-26)
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)
Patient Radiation Exposure During Interventional Procedures is a Concern for Some Developing Countries
Interventional radiology procedures are on the rise in developing countries and there is a significant need for optimization of these procedures to ensure patient safety. view more (2009-08-04)
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)
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)
Ultrasound more cost efficient than other medical imaging choices
In comparing ultrasound with other medical imaging methods such as MRI and CT scans, a literature review of published studies in the May/June issue of Journal of Diagnostic Medical Sonography (JDMS) describes the use of ultrasound to provide an accurate diagnosis more cost effectively than the alternatives. view more (2009-05-21)
Study examines novel PFO closure system
A new device designed to close a common heart defect known as a patent foramen ovale (PFO) is safe and effective at 90-days follow up, according to a new study released today at the Society for Cardiovascular Angiography and Interventions (SCAI) 32nd Annual Scientific Sessions in Las Vegas. view more (2009-05-11)
Ethnicity affects timing and access to cardiac care
Ethnicity is having a significant impact on timely access to cardiac care in Calgary and likely across Canada as the population's ethnic diversity grows, according to new research led by a team from the University of Calgary. view more (2009-05-06)
Educating Physicians About Ventilation-Perfusion Scanning Leads to Reduced Patient Radiation Exposure
Educating physicians about ventilation-perfusion scanning (VQ) as an alternative to CT for the diagnosis of pulmonary embolisms led to a 23% decrease in patient exposure. view more (2009-04-24)
Large congenital and solitary intrahepatic arterioportal
A case report to be published on April 7, 2009 in the World Journal of Gastroenterology reported incidental findings of a large and solitary congenital APF in a 73-year-old woman. view more (2009-04-15)
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)
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)
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)
