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
AI assesses cardiovascular risk on routine chest CT
December 12, 2017 -- An artificial intelligence (AI) algorithm can automatically quantify coronary and other arterial calcification from routine chest CT studies, enabling cardiovascular risk assessment to be performed on these patients, Dutch researchers reported at the RSNA 2017 meeting.  Discuss
Deep learning can quantify CAC on low-dose CT
November 29, 2017 -- CHICAGO - A deep-learning algorithm can automatically calculate coronary artery calcium (CAC) scores from lung cancer screening CT exams and facilitate risk stratification in these patients, according to research presented on Tuesday at RSNA 2017.  Discuss
MRI discovers heart damage among male triathletes
November 24, 2017 -- Using late gadolinium-enhanced MRI scans, German researchers found myocardial fibrosis, or scarring of the heart, among competitive male triathletes. An increased risk of scarring was associated with the amount of exercise performed, according to the group, who will present the study at next week's RSNA meeting in Chicago.  Discuss
Turin team illuminates CT use in cardiac surgery
November 21, 2017 -- The latest generation of CT scanners can provide excellent images of the coronary arteries, aortic annulus, and aortoiliac anatomy at a low contrast volume and a low radiation dose, even in patients with an irregular heartbeat or a high heart rate, according to new research from Turin, Italy.  Discuss
3D modeling progresses in structural heart disease
November 17, 2017 -- A 3D image reconstruction technique can combine functional and anatomical heart data, enabling practical descriptions of scarred tissue from cardiac anomalies revealed by electrocardiography, according to research presented at the recent European Society of Cardiovascular Radiology in Milan.  Discuss
MRI becomes safer for patients with heart-valve prosthesis
November 13, 2017 -- Evidence about the use of MRI in patients with a heart-valve prosthesis remains inconclusive, but the latest data support the hypothesis of a low or negligible interaction with MRI, according to research from the European Society of Cardiovascular Radiology congress in Milan.  Discuss
