3D printing can identify device size for LAA occlusion
March 13, 2018 -- Determining the best occluder device size necessary to properly seal the left atrial appendage (LAA) before implanting the device may be feasible with the assistance of 3D printing, according to two separate presentations at ECR 2018 in Vienna.
Hospitals begin to tap vast potential of 3D printing
March 8, 2018 -- Medical 3D printing services company 3D LifePrints is on the expansion trail. It creates surgical planning models for cardiac, orthopedic, and craniofacial cases, based predominantly on CT and MR images, and it is also focusing on 3D printing of medical device prototypes and surgical tools such as bespoke cutting guides.  Discuss
Size matters: Belgians scoop ECR 2018 prize for dose study
February 28, 2018 -- VIENNA - Body size has an influence on the dose conversion factors of a conventional chest posteroanterior examination for the organs in the field-of-view, except for the thyroid, according to an award-winning Belgian study being presented this week at ECR 2018.  Discuss
Is CT or MR perfusion better for diagnosing CAD?
February 15, 2018 -- Recent advances in scanner technology have made the use of CT stress myocardial perfusion imaging feasible. Just how well it matches up to MR perfusion in the diagnosis of coronary artery disease (CAD) is the central question of a German/U.S. study led by Dr. Marc Dewey from Berlin.  Discuss
Machine learning can help assess atherosclerosis
February 7, 2018 -- Machine-learning techniques analyze imaging measurements to automatically stratify patients by the level of atherosclerotic burden, offering the potential of personalized prediction of disease progression and more effective treatment for individual patients, according to researchers from Italy.  Discuss
PET/MRI proves value in cardiac sarcoidosis detection
January 23, 2018 -- U.K. researchers are recommending the use of PET/MRI to assess suspected cases of cardiac sarcoidosis, with late gadolinium enhancement and FDG uptake as the key indicators of disease, according to a study published online on 8 January in the European Heart Journal.  Discuss
3D printing technique lowers cost of modeling stenosis
January 16, 2018 -- Radiologists can plan and simulate vascular procedures on patient-specific and cost-effective 3D-printed stenosis models by using a new technique developed in Basel, Switzerland. Researchers generated stenotic vessel replicas at a more affordable price than what's currently available.  Discuss
3D volumetry shows promise in lung but requires care
January 12, 2018 -- Volumetry measurement of lung nodules is gaining clinical acceptance but still poses significant practical difficulties, and major factors of variability are related to the nodule, technical scanner parameters, and hemodynamic issues, according to U.K. researchers.  Discuss
How often are lung nodules missed on CAC scoring scans?
January 2, 2018 -- If an incidental lung nodule is present on a CT coronary artery calcium (CAC) scoring scan, how often is that nodule actually detected and worked up? Not as often as one might expect, according to researchers who analyzed the reasons why nodules might be missed in a presentation at RSNA 2017.  Discuss
CT can pinpoint cardiac metastases in malignant melanoma
December 19, 2017 -- CT tends to underestimate cardiac metastases in malignant melanoma patients, and to reduce morbidity and mortality in these cases, awareness is essential of different types of cardiac metastases and their characteristic appearance on CT, German researchers have found.  Discuss
