June 2010 Briefing - Radiology
Here are what the editors at HealthDay consider to be the most important developments in Radiology for June 2010. This roundup includes the latest research news from journal articles, as well as the FDA approvals and regulatory changes that are the most likely to affect clinical practice.
Use of Imaging-Guided Biopsies Steadily Growing
TUESDAY, June 29 (HealthDay News) -- Imaging-guided percutaneous biopsy (IGPB) as a percentage of all biopsies is steadily rising, and radiologists are performing an increasing percentage of biopsies, according to research published online June 29 in Radiology.
MRI Signs Predict Hypertrophic Cardiomyopathy Event Risk
THURSDAY, June 24 (HealthDay News) -- Visualization of cardiac scar tissue and gadolinium enhancement on cardiac magnetic resonance (CMR) imaging each predict an increased risk of a major cardiovascular event in patients with hypertrophic cardiomyopathy (HCM), according to two studies published online June 23 in the Journal of the American College of Cardiology.
Imaging Combo Holds Promise for Breast Cancer Detection
TUESDAY, June 22 (HealthDay News) -- Ultrasound-guided optical tomography appears to be an effective means for differentiating early-stage breast cancers from benign lesions, and it has the potential to reduce the number of breast biopsies women undergo for suspicious lesions, according to research published online June 22 in Radiology.
Colon Capsule Endoscopy Detects Polyps Effectively
MONDAY, June 21 (HealthDay News) -- Colon capsule endoscopy (CCE) appears to be an effective noninvasive colorectal cancer (CRC) screening technique, as its sensitivity for polyps and significant findings compares favorably with other noninvasive CRC screening approaches, according to research published in the June issue of Clinical Gastroenterology and Hepatology.
Computed Tomography Angiography May Be Avoidable
WEDNESDAY, June 16 (HealthDay News) -- The risk of a computed tomography (CT) angiogram being positive for pulmonary embolism (PE) is unlikely among patients who do not present with thromboembolic risk factors, suggesting that CT angiography is unnecessary in many patients, according to research published online June 15 in Radiology.
Presence of Alzheimer's Genes Influences Brain Imaging
MONDAY, June 14 (HealthDay News) -- The presence of established Alzheimer's disease (AD) genes, and a pair of promising and novel AD genes, influence the brain characteristics seen in magnetic resonance imaging (MRI) studies of patients with the disease, according to a study in the June issue of the Archives of Neurology.
Incidental Findings Frequently Seen in Pediatric Brain Imaging
MONDAY, June 14 (HealthDay News) -- Nearly 7 percent of children involved in a magnetic resonance imaging (MRI) study had incidental intracranial findings, calling attention to issues related to counseling families when such findings arise in clinical situations, according to research published online June 14 in Pediatrics.
No Increased Mortality Seen With Ultrasound Contrast Agent
THURSDAY, June 10 (HealthDay News) -- There is no increased mortality risk for critically ill patients who undergo echocardiography with an ultrasound contrast agent (UCA), compared to those who do not have contrast during their echocardiogram, according to research published in the June issue of the Journal of the American College of Cardiology: Cardiovascular Imaging.
Abdominal Aortic Aneurysm Not Uncommon in CABG Patients
WEDNESDAY, June 9 (HealthDay News) -- Among patients who have undergone coronary artery bypass grafting (CABG), abdominal aortic aneurysms (AAAs) are particularly common in men with a history of smoking and other vascular problems, including peripheral arterial disease (PAD), according to research published in the June 1 issue of the American Journal of Cardiology.
3-D Echo With Contrast Shows Promise for Infarct Scars
WEDNESDAY, June 2 (HealthDay News) -- Contrast-enhanced 3-D echocardiography may be a useful tool for detecting and assessing myocardial infarct scars, according to research published online June 1 in Circulation: Cardiovascular Imaging.
Ultrasound Identifies Patients at Higher Stroke Risk
WEDNESDAY, June 2 (HealthDay News) -- The detection of asymptomatic embolic signals using transcranial doppler (TCD) may help identify groups of patients with asymptomatic carotid stenosis who are at low or high risk of stroke, which could be useful in identifying those most likely to benefit from endarterectomy, according to a study published online May 28 in The Lancet Neurology to coincide with its presentation at the European Stroke Conference, held from May 25 to 28 in Barcelona, Spain.
