MDCT accurate in detecting stenosis in calcified coronary artery plaque
Multidetector CT angiography can accurately predict the presence of obstructive disease (stenosis) in small and moderate-sized calcified coronary artery plaque (CAP), and is even fairly accurate in diagnosing large and heavily calcified CAP, according to a recent study conducted by researchers at Thomas Jefferson University Hospital in... view more...

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)
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)
SAPPHIRE trial shows long-term benefit of carotid stenting as alternative to surgery
Carotid artery stenting is an effective option for high risk patients who are not eligible for surgery, according to a long-term study published in this week's New England Journal of Medicine. Carotid artery disease, which involves clogging of the arteries in the neck that provide blood to the brain, is a significant risk factor for stroke, making... view more... (2008-04-11)
High intracoronary attenuation improves accuracy of 64-slice CT-CA
High intracoronary attenuation significantly improves diagnostic accuracy in 64-slice CT-CA of the coronary arteries. view more (2007-05-07)
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)
Computed tomography provides anatomy -- we need ischemia!
Cardiac computed tomography has revolutionized cardiac imaging in recent years by providing exquisitely detailed cardiac anatomy, including, but not limited to, coronary anatomy. view more (2008-09-02)
ESC Congress 2003: Stenting for acute myocardial infarction
IMPORTANT: This press release accompanies a poster or oral session given at the ESC Congress 2003. Written by the investigator himself/herself, this press release does not necessarily reflect the opinion of the European Society of Cardiology ESC Congress 2003: We have found that in patients with acute myocardial infarction (AMI) treated with... view more...

Novel Non-Invasive Imaging Technology May Allow Precise Diagnosis of Coronary Artery Disease, Treatment Tailoring
A study focusing on a new non-invasive imaging technology—one that may enable more precise diagnosis of coronary artery disease and treatment tailoring in individual patients—was released by Israeli researchers at SNM's 53rd Annual Meeting June 3—7 in San Diego. view more (2006-06-08)
Researchers find predictor of mortality in cardiac patients
Researchers at SUNY Downstate Medical Center in Brooklyn have determined that low levels of a protein in the blood is a predictor of cardiac death in patients with coronary artery disease. view more (2007-02-21)
CTA useful in detecting ruptured cerebral aneurysms
CT angiography (CTA) has a nearly 100% detection rate in acute ruptured, cerebral aneurysms, according to a recent study conducted at the Health Sciences Center in Winnipeg, Canada. view more (2007-05-07)

The intraductal papillary mucinous neoplasms (IPMN) can evolve through all biological stages, from slight dysplasia to carcinoma. view more (2009-09-16)
Pretreating vein graft does not help prevent graft failure in coronary artery bypass surgery
Pretreating a vein graft with edifoligide prior to coronary bypass graft surgery does not lower the rate of graft failure. view more (2005-11-14)
CHEST, HEART AND STROKE SCOTLAND FUND CORONARY BALLOON ANGIOPLASTY RESEARCH
Chest, Heart and Stroke Scotland have awarded a grant of £28,865 to support the work, which will look at the part played by angioplasty balloon pressure in the sudden closure of blood vessels. Subsequent problems for the patient can include heart attack and/or emergency coronary bypass surgery. Says Dr Nick Palmer, Clinical Research Fellow... view more... (1999-01-22)
Shining light on diabetes-related blindness
A group of scientists in California is trying to develop a cheaper, less invasive way to spot the early stages of retinal damage from diabetic retinopathy, the leading cause of blindness in American adults, before it leads to blindness. view more (2009-03-12)
Allergic reactions to gadolinium-based contrast agents are rare, study finds
Allergic-like reactions to gadolinium-containing contrast injections in adults and pediatric patients (those younger than 19 years of age) are rare, according to a recent study conducted by researchers at the University of Michigan Health Systems in Ann Arbor. view more (2007-12-28)
Brain-damage Threat From Invasive Assessment Of Heart-valve Stenosis (p 1241)
Authors of a study in this week's issue of THE LANCET warn against the widespread use of catheterisation to assess the extent of aortic-valve stenosis--this invasive procedure could increase the risk of cerebral blood clotting and brain damage. The severity of valvular aortic stenosis (a narrowing of the valve between the left ventricle of the... view more... (2003-04-09)
New research explores limits of non-invasive coronary imaging tests
If multi-slice computed tomography (MSCT) shows that a patient has plaque build-up in the artery walls, does it also mean that there is actual reduced blood flow in the artery\\\ view more (2006-12-12)
Endurance Athletes Could Benefit From Surgical Release Of Kinked Leg Arteries (p 466)
Flow restrictions in leg arteries of endurance athletes are commonly caused by kinking and could be easily resolved by a straightforward surgical procedure, conclude authors of a study in this week's issue of THE LANCET. Endurance athletes-especially cyclists and speed skaters-often have restrictions in blood flow in their iliac arteries (the... view more... (2002-02-06)
Statins prove life-saving in patients with acute coronary syndromes
Patients who begin aggressive statin therapy while in the hospital for acute coronary syndromes (ACS) have a significantly greater chance of long-term survival. view more (2006-05-12)
