Regional variations in T1 in the healthy left ventricle
Methods We assessed regional variation in T1 in the septum of patients with no left ventricular pathology. An adjunct phantom study was performed to assess whether location closer to a surface coil affected T1. Main study: Retrospective. 40 patients whose cardiac MRI showed no left ventricular disease were identified. Patients were imaged on a Siemens Avanto 1.5T scanner with a 32-channel cardi...
متن کاملT1 Mapping in Athletes
Cardiac adaptation to high-intensity exercise is well recognized and often termed the athlete’s heart. The characteristic features of athlete’s heart are increased left ventricular (LV) volume, increased LV wall thickness and mass, resting bradycardia, and ECG repolarization abnormalities. These changes are particularly associated with endurance training causing eccentric LV hypertrophy, wherea...

متن کاملMapping collective behavior--beware of looping.
We discuss ambiguities of the two main dimensions of the map proposed by Bentley and colleagues that relate to the degree of self-reflection the observed agents have upon their behavior. This self-reflection is a variant of the "looping effect" which denotes that, in social research, the product of investigation influences the object of investigation. We outline how this can be understood as a ...
متن کاملT1 Mapping by CMR Imaging
Fro Ge He Sie infl La Ph Ma OBJECTIVES The purpose of this study was to prospectively investigate the diagnostic and prognostic impact of cardiac magnetic resonance (CMR) T1 mapping and validate it against left ventricular biopsies. BACKGROUND Extracellular volume (ECV) expansion is a key feature of heart failure. CMR T1 mapping has been developed as a noninvasive technique to estimate ECV; how...
