[Assessment of regional myocardial function by ECG-gated myocardial SPECT].
PURPOSES Regional myocardial functional parameters were assessed by ECG-gated myocardial SPECT analysis in normal subjects and ischemic heart diseases. METHODS Normal subjects (13 male and 10 female) and 51 patients with chronic ischemic heart disease underwent ECG-gated myocardial SPECT. A dose of 740 MBq of 99mTc-MIBI was injected at rest, and gated SPECT was performed 60 min later. Wall mo...
متن کاملAssessment of regional myocardial work in rats.
BACKGROUND Left ventricular (LV) motion and deformation is dependent on mechanical load and do therefore not reflect myocardial energy consumption directly. Regional myocardial work, however, constitutes a more complete assessment of myocardial function. METHODS AND RESULTS Strain was measured using high-resolution phase-contrast MRI in 9 adult male rats with myocardial infarction (MI) and in...
متن کاملMyocardial tactile stiffness: a variable of regional myocardial function.
OBJECTIVES We developed a new sensor system for in situ measurement of myocardial tactile stiffness-stiffness in a direction perpendicular to the wall-and validated its use for providing a reasonable estimation of regional myocardial function. BACKGROUND Numerous attempts have been made to directly assess regional myocardial function. The complexity and highly invasive nature of the measuring...
متن کاملAssessment of Regional Myocardial Function via Statistical Features in MR Images
Early and accurate detection of Left Ventricle (LV) regional wall motion abnormalities significantly helps in the diagnosis and followup of cardiovascular diseases. We present a regional myocardial abnormality detection framework based on image statistics. The proposed framework requires a minimal user interaction, only to specify initial delineation and anatomical landmarks on the first frame....
متن کاملRadionuclide assessment of regional left ventricular function in acute myocardial infarction.
To determine changes in global and regional left ventricular function following acute myocardial function, 17 patients underwent radionuclide angiography at 3 and 10 days post infarction. Five patients had nontransmural myocardial infarction and 12 had transmural infarction (six anterior and six inferior). There were no previous infarctions in 16 (94%) patients. Regional ejection fractions were...
