Standardized phantoms for quantitative cardiac MRI
Background Quantitative MR relaxometry techniques are increasingly used in cardiac MR applications, e.g. MOLLI for high resolution T1 mapping. To use these techniques in the clinic, we must understand how to make comparable measurements across vendor systems and software versions and compare results across sites. A standardized phantom used for regular quality control is one approach. The Bioma...
متن کاملIntegrated quantitative first-pass cardiac perfusion MRI protocol
Methods A multi-slice saturation recovery (SR) pulse sequence with sequential SR time delays (TD) after a non-selective saturation pulse [2] was implemented at 3T (Fig. 1). The rationale for this acquisition scheme was to acquire a dedicated arterial input function (AIF) image with a short TD (50ms) in the aortic root and short-axis myocardial images with longer TD values (~150-400ms), to allow...
متن کاملEvaluation of cardiac valvular regurgitant lesions by cardiac MRI sequences: comparison of a four valve semi-quantitative vs. quantitative approach
BACKGROUND AND AIM OF THE STUDY Cardiac magnetic resonance (CMR) imaging generally allows a more accurate and valid quantification of cardiac function, mass and regurgitant volumes than echocardiography. Although recent technological advancements in CMR have made the evaluation of cardiac valves more reliable, no studies have yet been conducted to compare semi-quantitative grading (SQG) using C...
متن کاملCardiac MRI
Introduction Cardiac MR imaging allows for the examination of anatomy, function, and metabolism and its clinical use is steadily increasing. It poses unique challenges to the imaging protocols as it requires high spatial resolution over a larger volume in the presence of cardiac and breathing motion. This overview of cardiac MRI discusses methods to reduce motion artifacts and various clinical ...
متن کاملCardiac MRI at 7T
In the brain, results have been shown at 7T that are not achievable at lower field strengths. Cardiac imaging at 7T offers similar headline benefits to those images of the brain. More field strength gives more SNR, added to which more field strength increases the T1 and hence increases the effect of contrast agents. This simple idea is appealing in a grant application, but in reality 7T has som...
