UAE steps up campaign on dose awareness September 22, 2016 -- Moves to limit medical radiation exposure are intensifying in the United Arab Emirates (UAE), and safety issues and education now are high on the agenda of healthcare professionals. Every effort must be made to reduce exposure and boost risk awareness, according to key participants at next month's summit in the region.
Action on CT dose brings results in Middle East September 19, 2016 -- A multicenter study conducted in Saudi Arabia and the United Arab Emirates has underlined the value of implementing dose-reduction techniques for coronary CT angiography and coronary calcium score examinations.
Researchers close in on radiation's cancer-causing mechanisms September 12, 2016 -- U.K. researchers studying human cancers have identified two characteristic patterns of DNA damage caused by ionizing radiation, enabling doctors to potentially determine which tumors were caused by radiation exposure, according to a study published on September 12 in Nature Communications.
CCTA plus SPECT offer solid long-term prognosis September 8, 2016 -- Patients with positive findings on both coronary CT angiography (CCTA) and SPECT myocardial perfusion imaging are at high risk of cardiac events, while negative results on both exams confer an excellent long-term prognosis, according to researchers from Switzerland.
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.
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.
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.
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.
Germany orders 20% reduction in DRLs for radiation dose August 25, 2016 -- Stating that more progress is needed in reducing patient exposure to radiation dose, German regulatory authorities on Tuesday announced a 20% reduction in diagnostic reference levels (DRLs) for radiation from medical imaging procedures. The move could require some facilities to replace aging equipment.
