$Noninvasive fractional flow reserve still out of reach$

Noninvasive fractional flow reserve still out of reach

A novel, noninvasive approach to determining fractional flow reserve failed to show sufficient diagnostic accuracy to meet the primary endpoint of the DeFACTO trial, but was more accurate for diagnosing coronary artery ischemia than computed tomography, reported the trial’s lead investigator.

CT scan appears to predict risk of chronic obstructive pulmonary disease exacerbations

The respective size of two major arteries, visible on a simple computed tomography, or CT, scan, is a strong predictor of the risk of exacerbation of chronic obstructive pulmonary disease, according to new research from the University of Alabama at Birmingham published online Sept. 3, 2012, in the New England Journal of Medicine.

Some smaller clots may not require potentially risky treatment

Men and women who undergo joint replacement procedures, as well as those who have significant fractures, tend to be at an increased risk of developing pulmonary emboli (PE), blood clots that travel to the lungs where they may cause serious complications and even death.

Ultra-fast 320-detector CT scanner can accurately diagnose arterial blockages

An ultra-fast, 320-detector computed tomography (CT) scanner can accurately sort out which people with chest pain need - or don't need - an invasive procedure such as cardiac angioplasty or bypass surgery to restore blood flow to the heart, according to an international study. Results of the study, which involved 381 patients at 16 hospitals in eight countries, are scheduled to be presented at the European Society of Cardiology Congress in Munich, Germany, on August 28.

Addition of CTP to CT angiography allows clinicians to identify flow-limiting coronary artery disease

A non-invasive imaging strategy which integrates non-invasive CT angiography (CTA) and CT myocardial perfusion imaging (CTP) has robust diagnostic accuracy for identifying patients with flow-limiting coronary artery disease in need of myocardial revascularisation, according to results of the CORE320 study presented here today by Dr Joao AC Lima from Johns Hopkins Hospital, Baltimore, USA.

Edge CT now available in NYU Langone's Department of Radiology clinical practice

NYU Langone Medical Center is the first in the country to offer patients access to the new Siemens Somatom Definition Edge single-source computed tomography system (Edge CT), one of the world's fastest CT scanners capable of generating high quality, 3-D diagnostic images using extremely low radiation.

Nearly 7% of urologic MDCT scans for hematuria result in incidental findings

A new study from Rhode Island Hospital reports that nearly seven percent of urologic multi-detector computed tomography (MDCT) scans for hematuria result in incidental findings that may be clinically important for the patient. The study is published in the American Journal of Roentgenology.

Vision symptoms plus retinal changes trigger need for AMD intervention

An analysis of over 1000 individuals presenting with suspected exudative age-related macular degeneration has revealed which factors are most predictive of the need for treatment.

New medical technology improves image quality and reduces radiation

Particle physicists have developed a new medical technology that combines PET and MRI in one. Benefit: Improved image quality and less radiation.

Scientists devise new fluorescent probes to diagnose neurodegenerative diseases

Sticky plaques of proteins called amyloids mark several different, though related degenerative brain diseases including Alzheimer's, Parkinson's and Creutzfeld-Jacobs. The symptoms of these disorders overlap and methods to diagnose and monitor them are not very advanced.

No aping around after anesthetic combination

A combination of medetomidine and ketamine administered intramuscularly to chimpanzees, orangutans, and gorillas results in reliable immobilization for both the animals and personnel handling them, report researchers.

Abdominal pain duration influences appendicitis imaging diagnosis

Clinicians should not rely on ultrasonography for diagnosing pediatric appendicitis early in the course of illness, say US researchers.

High-cost imaging increasingly used for stage IV cancer patients

High-cost diagnostic imaging was increasingly used for elderly patients with stage IV cancer of the breast, lung, and prostate, and colorectal cancer in the USA, research demonstrates.

NYU Langone offers chance to participate in lung cancer early detection study

NYU Langone Medical Center is a pioneer in lung cancer screening and offers comprehensive screening for individuals at risk for lung cancer. The NYU Langone Lung Cancer Screening Center is distinguished by its multidisciplinary approach and wealth of experience and is under the direction of the Divisions of Pulmonary Medicine, Thoracic Radiology and Thoracic Surgery.

Hydrocephalus dictates age-related SAH outcomes

Age is only predictive of poor outcome after aneurysmal subarachnoid hemorrhage because of its association with hydrocephalus, say researchers.

$Thoracolumbar vertebrae fracture may be ‘silent’$

Thoracolumbar vertebrae fracture may be ‘silent’

Imaging is essential to avoid missing fractures to the thoracolumbar vertebrae in patients who have sustained blunt injury, UK researchers say.

Recurrences of ovarian cancer can be detected earlier and more accurately with PET/CT

Due to the lack of studies, there is currently no proof that patients with ovarian cancer can benefit from positron emission tomography (PET) alone or in combination with computed tomography (CT). As regards diagnostic accuracy, in certain cases, recurrences can be detected earlier and more accurately with PET or PET/CT than with conventional imaging techniques.

Increases in NSCLC survival 'an artefact of PET assessment'

There has been no increase in survival among non-small-cell lung cancer patients in recent years, with evidence suggesting otherwise likely due to positron emission tomography-induced stage migration and selection bias, say US scientists.

Advanced Radiology to offer Amyvid for detection of AD

Advanced Radiology, a division of RadNet, Inc., a national market leader providing high-quality, cost-effective diagnostic imaging services through a network of 237 fully-owned and operated outpatient imaging centers, announced it will be one of a small number of imaging centers in the U.S. to offer Amyvid, a radioactive tracer used in positron emission tomography – computed tomography (PET/CT) imaging that helps to detect the quantity of beta-amyloid plaque in patient's brains.

Scientists discover important neural mechanism underlying dyslexia

To participate successfully in life, it is important to be able to read and write. Nevertheless, many children and adults have difficulties in acquiring these skills and the reason is not always obvious. They suffer from dyslexia which can have a variety of symptoms. Thanks to research carried out by Bego-a D-az and her colleagues at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, a major step forward has been made in understanding the cause of dyslexia.
