Accelerated whole-heart 3D CSPAMM for myocardial motion quantification.
Myocardial tissue tagging using complementary spatial modulation of magnetization (CSPAMM) allows detailed assessment of myocardial motion. To capture the complex 3D cardiac motion pattern, multiple 2D tagged slices are usually acquired in different orientations. These approaches are prone to slice misregistration and associated with long acquisition times. In this work, a fast method for acqui...
متن کامل3D Whole Heart CSPAMM tagging in a single breath hold using k-t-PCA
Introduction Myocardial tagging techniques [1, 2] have shown great promise in assessing local wall motion abnormalities. Recent work has indicated the value of the method in stratifying patients for cardiac resynchronization therapy [3]. Three-dimensional data acquisition is a prerequisite for a comprehensive analysis of cardiac motion. The combination of reduced field-of-view and line tag prep...
متن کاملReproducibility of strain and twist measurements calculated using CSPAMM tagging
Methods 12 healthy volunteers (6 males, mean age 33±7 years) underwent CMR studies on a 1.5T system (Intera CV, Philips Healthcare, The Netherlands). Tagged CMR images were acquired at the apex, mid-ventricle and base with a CSPAMM pulse sequence (field of view: 300mm, matrix 128 x 128, slice thickness 10mm, tag separation 8mm, 18 phases, typical TR/TE 30ms/6ms, flip angle 25 degrees). In 6 vol...
متن کاملMyocardial tissue tagging with cardiovascular magnetic resonance
Cardiovascular magnetic resonance (CMR) is currently the gold standard for assessing both global and regional myocardial function. New tools for quantifying regional function have been recently developed to characterize early myocardial dysfunction in order to improve the identification and management of individuals at risk for heart failure. Of particular interest is CMR myocardial tagging, a ...
متن کاملImaging Myocardial Tagging
It has been postulated that rotation of the left ventricular apex with respect to the base is a component of normal systolic function in humans, but it has been difficult to measure it noninvasively. Tagging is a new magnetic resonance imaging technique that labels specific areas of myocardium by selective radio-frequency excitation of narrow planes orthogonal to the imaging plane before acquir...
