CT perfusion salvages nondiagnostic CTA for stent assessment
June 18, 2013 -- Combining CT perfusion scans with CT angiography (CTA) can improve the diagnosis of coronary artery disease in stent patients, visualizing stenotic vessel segments that CTA alone is hard-pressed to characterize, German researchers reported today in the Journal of the American College of Cardiology.
Simple guidelines can improve appropriateness of CCTA referrals
June 12, 2013 -- LIVERPOOL, U.K. - As cardiac CT services are accessed by an ever wider range of referrers, ongoing education is needed to ensure appropriate use, and simple guidelines can achieve this effectively for cardiac CT angiography (CCTA), a leading group of researchers told attendees at this week's U.K. Radiological Conference.
U.K. issues free guidelines on clinical PET/CT
May 29, 2013 -- All imaging specialists who are involved in relevant multidisciplinary teams must develop a good working knowledge of PET/CT, and teamwork is essential to ensure the highest standards, according to guidance published this month by the U.K. Royal College of Radiologists.
Study shows feasibility of cardiac PET/MRI -- with caveats
May 13, 2013 -- Cardiac FDG-PET/MRI is feasible on an integrated whole-body PET/MRI system, but the hybrid modality still must prove it adds clinical relevance to cases of ischemic heart disease, according to a German study published online on 7 May in Radiology.
Hannover group targets inflammation in cardiac disease
May 6, 2013 -- An established treatment for cancer patients can offer a novel therapeutic approach to decrease the levels of inflammation in the atherosclerotic plaques of patients with cardiovascular disease, German researchers have found.
Postmortem MRI shows sudden cardiac death invisible at autopsy
May 2, 2013 -- In results that add substantial forensic power to identifying the cause of death, postmortem cardiac 3-tesla MRI has been found to identify sudden cardiac death in cases that are invisible at conventional autopsy, according to new research published online in the Journal of the American College of Cardiology.
ACE inhibitors can limit damage to heart, lungs from radiotherapy
April 24, 2013 -- Administration of an angiotensin-converting enzyme (ACE) inhibitor used in the treatment of cardiovascular disease may help protect radiation damage to the heart and lungs from radiotherapy treatment of cancers in the chest region, according to a presentation at the European Society for Radiotherapy and Oncology.
Reader experience tied to CCTA accuracy
April 23, 2013 -- Training and experience wield a huge effect on reader accuracy in coronary CT angiography (CCTA) interpretation, and current minimum standards may not be sufficient, concluded a new study published online in the European Journal of Radiology.
CT can sub for MRI in patients with ventricular tachycardia
April 11, 2013 -- Late-enhancement CT can replace MRI for preprocedural evaluation of myocardial scar in patients with ventricular tachycardia (VT), according to a study from Italy. That's good news because CT actually needs to replace MRI for preprocedural planning in many VT patients who have contraindications to MRI.
Virtual autopsies get boost from cardiac imaging advances
April 9, 2013 -- A team from the U.K. has reported that adding cardiac CT angiography to routine CT for postmortem imaging in suspected cases of death by coronary artery disease significantly increases the accuracy of virtual autopsies.
Radiotherapy boosts heart disease risk in breast cancer patients
March 20, 2013 -- Radiation therapy has played a key role in reducing breast cancer mortality rates, but even at low doses it can increase a woman's risk of heart disease, according to new research from the University of Oxford in the U.K. published on 14 March.
CT of mummies finds heart disease an ancient problem
March 11, 2013 -- Using CT to image mummies from four different geographical regions -- and spanning 4,000 years of human history -- researchers have found that heart disease was common among ancient people, according to a study published online on Sunday in Lancet.
Integrated CT detector improves coronary stenosis assessment
March 10, 2013 -- VIENNA - A new integrated circuit CT detector may improve the ability of clinicians to accurately grade coronary artery stenoses visualized during coronary CT angiography, especially when combined with thin-slice imaging and iterative reconstruction, researchers reported on Sunday at ECR 2013.
Adults with congenital heart disease represent growing challenge
March 9, 2013 -- VIENNA - Thanks to medical progress, most babies born with congenital heart disease (CHD) now survive to adulthood. Imaging is critical for these patients, and it's important for radiologists to become familiar with the most common CHD imaging aspects and surgical procedures, according to a special focus session on Saturday at ECR 2013.
CT vendors focus on iterative reconstruction, cardiac applications
March 8, 2013 -- VIENNA - Innovation in software technologies provides the main talking points for visitors to the CT equipment vendors' booths at the ECR 2013 commercial exhibition. Companies are demonstrating novel approaches to reducing radiation dose, improving image quality, and extending the modality's capabilities in cardiac imaging.
