Identifying and quantifying diffuse myocardial fibrosis is important to provide insights into the relationship between myocardial fibrosis, diastolic and systolic dysfunction, as well as clinical outcomes. T1 mapping is a promising technique for noninvasively identifying diffuse myocardial fibrosis in heart failure. A quantitative T1 map provides sensitivity to the full range of T1 values and is advantageous over the traditional T1-weighted imaging by reducing the reliance on visual interpretation of the signal intensity in the myocardium. However, in-vivo myocardial T1 quantification is challenging because of cardiac and respiratory motion. During the past few years, a variety of T1 mapping techniques, …

Advances in magnetic resonance imaging to quantify the blood flow in the heart and major vessels stemming from the heart has recently allowed for advanced clinical applications for patients suffering from cardiac valve problems and aortic abnormalities. 7D cardiac flow quantification is relatively new, but has already shown potential in several clinical applications, including bicuspid valve and aortic coarctation characterization. In addition radiologists diagnosing valvular regurgitation may benefit from insight provided by the 7D cardiac flow quantification protocol. 7D cardiac flow quantification using magnetic resonance imaging will provide direction flow quantification in the anterior / posterior, head / foot, and …
