Reconstruction kernel cuts artifacts in CT MPI
September 7, 2016 -- A new reconstruction algorithm can erase beam-hardening artifacts in myocardial perfusion imaging (MPI) in dual-source CT, bolstering the reliability of the increasingly popular examination, according to a U.S.-German study in European Radiology.
DNA damage comes under fresh scrutiny
September 7, 2016 -- Prompted by the lively recent debate about the possible carcinogenic risk in cardiac imaging for detecting coronary artery disease, Swiss researchers say they've found no significant differences between ultralow-dose coronary CT angiography and cardiovascular MRI.
Why we need to move away from taking pictures
September 6, 2016 -- "A picture is worth a thousand words." While that's true for everyday snapshots depicting a friend's smile or landscapes, simple picture taking is no option for medicine. Guest columnists from Austria explain why medical diagnosis cannot rest on a single picture.
Texture classification eases lung CT analysis
September 5, 2016 -- Dutch researchers have developed a semiautomatic method for classifying abnormal lung textures that reduces the time taken to analyze thoracic CT scans. They found the interactive labeling protocol is more efficient to use than a fully automated alternative.
U.K. pediatric radiology shortage puts kids at risk
September 2, 2016 -- National standards for pediatric imaging are not being met in a large number of centers in the U.K., putting thousands of children at risk, according to a recent audit. A way to solve the problem in the short term is to link up specialists with their colleagues, the researchers added.
OCT identifies heart patients who can forgo stenting
September 2, 2016 -- As many as one-fourth of heart attack patients who would normally have a stent implanted can forgo the procedure in favor of conservative management based on the results of optical coherence tomography (OCT), concluded U.S. researchers in a presentation at the European Society of Cardiology congress (ESC 2016) in Rome.
ESC: CT is effective gatekeeper for invasive angio
September 1, 2016 -- In stable patients with chest pain and suspected coronary artery disease, using coronary CT angiography to guide the selective use of invasive coronary angiography is safer and less expensive than sending patients directly to angiography, according to results presented on Monday at the European Society of Cardiology (ESC) congress in Rome.
PET/MRI's future tied to cost, scan time, key applications
September 1, 2016 -- Buoyed by its perceived superiority over PET/CT, early adopters of PET/MRI believe the hybrid modality could be used more often in routine clinical applications within the next five years. However, this trajectory could hit a speed bump.
ESC: How do cardiologists use Twitter?
August 31, 2016 -- ROME - Tweeting cardiologists are an even rarer breed than tweeting radiologists, it seems. Scottish researchers could only identify 94 cardiologists who use Twitter, 55 of whom are based in the U.S., delegates at the European Society of Cardiology (ESC) annual congress learned on Tuesday.
ESC: Danes shed new light on CT and chest pain
August 30, 2016 -- ROME - In patients with chest pain, should you use cardiac CT or functional testing? A large study from Denmark presented on Monday at the European Society of Cardiology (ESC) annual congress found advantages and disadvantages to the cardiac CT-based approach.
