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.

VIDA releases Apollo 1.2 SaaS for endobronchial emphysema treatment

VIDA Diagnostics, a leading developer of quantitative imaging analysis software for the diagnosis and treatment planning of major pulmonary disease, announced today the release and commercial availability of Apollo 1.2, here at the European Respiratory Society (ERS) meeting in Vienna, Austria.

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.

Boehringer Ingelheim announces data from olodaterol plus tiotropium Phase II COPD study

Boehringer Ingelheim presented today for the first time data from a Phase II dose ranging study investigationg the combination of olodaterol, an investigational long-acting beta2-agonist (LABA), and tiotropium, a long-acting muscarinic antagonist (LAMA), in COPD patients, compared to the investigational agent olodaterol alone.

First data from Boehringer Ingelheim’s Respimat Phase III asthma program

Boehringer Ingelheim presented today the first data from the Phase III UniTinA-asthma program. In two studies, presented at the 2012 European Respiratory Society (ERS) Congress in Vienna, Austria, tiotropium delivered once daily via the Respimat inhaler significantly improved lung function and reduced asthma exacerbations in patients who remained symptomatic on current treatment with at least high dose inhaled corticosteroids (ICS) and long-acting beta agonists (LABA).

DNA synthesis in the 3’ and 5’ direction possible using new template-directed method

When a cell divides, it passes on genetic information by producing copies of its DNA. Chemists have also learned to copy DNA. In the journal Angewandte Chemie, a German team has now introduced a new copying technique that uses a single strand of DNA as the “master copy”, like a cell, but does not require enzymes.

Fractional flow reserve CT shows potential to non-invasively identify coronary artery disease

A study published in the most recent issue of the Journal of the American Medical Association (JAMA) presented encouraging news regarding physicians' ability to determine blood flow and associated coronary artery disease (CAD) using noninvasive CT scanning technology.

Carnegie Hill Radiology in New York installs Aquilion PRIME 160 series from Toshiba

Patients with irregular heartbeats (arrhythmia) are difficult to image with CT. Addressing this challenge, Carnegie Hill Radiology in New York installed the Aquilion PRIME 160 series from Toshiba America Medical Systems, Inc., featuring SURECardio Prospective software that automatically adjusts for irregular heartbeats, providing quicker, more accurate exams.

FISH assay identifies only few lung cancer patients who could benefit from crizotinib

Break apart a couple worm-like chromosomes and they may reconnect with mismatched tips and tails - such is the case of the EML4-ALK fusion gene that creates 2-7 percent of lung cancers. Almost exactly a year ago, the FDA approved the drug crizotinib to treat these ALK+ lung cancer patients, who were likely never smokers. Informed doctors use the test called a FISH assay to check for the EML4-ALK fusion gene, and then if the test is positive, ALK+ patients benefit greatly from crizotinib.

Catheter ablation for Afib is safe and suppresses arrhythmia recurrences

Catheter ablation for atrial fibrillation (Afib) is safe and suppresses arrhythmia recurrences in 74% of patients after a single procedure, according to results from the one-year follow-up of the Atrial Fibrillation Ablation Pilot Study, the first European registry to evaluate the real-life epidemiology of catheter ablation for AFib.

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.

$Noninvasive fractional flow reserve superior to CT in identifying individuals with ischemia$

Noninvasive fractional flow reserve superior to CT in identifying individuals with ischemia

Among patients with suspected or known coronary artery disease, use of a method that applies computational fluid dynamics to derive certain data from computed tomographic (CT) angiography demonstrated improved diagnostic accuracy vs. CT angiography alone for the diagnosis of ischemia, according to a study being published online by JAMA.
