Diagnostic performance of 3T stress magnetic resonance myocardial perfusion imaging (MRMPI) using 32-channel cardiac coil in patients with coronary artery disease
Background/aim With newly available 32-channel cardiac coil, 3 tesla MRI system provides increased signal-to-noise radio (SNR), reduced imaging time and improved spatial resolution. This study sought to determine the diagnostic performance of 3T stress MRMPI with 32-channel cardiac coil in detecting clinical relevant coronary artery stenosis in comparison with invasive coronary angiography (ICA).
متن کاملThree dimensional first-pass myocardial perfusion imaging at 3T: feasibility study
BACKGROUND In patients with ischemic heart disease, accurate assessment of the extent of myocardial perfusion deficit may be important in predicting prognosis of clinical cardiac outcomes. The aim of this study was to compare the ability of three dimensional (3D) and of two dimensional (2D) multi-slice myocardial perfusion imaging (MPI) using cardiovascular magnetic resonance (CMR) in determini...
متن کاملSteady-state first-pass perfusion (SSFPP): A 3D TWIST in myocardial first-pass perfusion imaging
A new approach to myocardial first-pass perfusion imaging is presented; this technique, called SSFPP, is based on 3D SSFP sequence whereby magnetization is maintained in constant steady-state, while data acquisition is gated to diastole. This results in high SNR and CNR, and other characteristics that can potentially mitigate dark rim artifacts. The high-blood myocardial contrast of SSFP allows...
متن کاملCombination of Compressed Sensing, Parallel Imaging and Partial Fourier for Highly-Accelerated 3D First-Pass Cardiac Perfusion MRI
Introduction: First-pass myocardial perfusion MRI is a promising and noninvasive technique for evaluation of ischemic heart disease. 3D whole-heart coverage per heartbeat is desirable for clinical perfusion studies to overcome the contrast-to-noise ratio (CNR) and volumetric coverage limitations associated with multi-slice 2D perfusion MRI studies [1-2]. Highly accelerated imaging is a necessar...
متن کاملFully automated pixel-wise myocardial blood flow quantification with first-pass perfusion CMR
Methods Rest and adenosine stress perfusion imaging was performed on 17 normal volunteers. A saturation recovery SSFP dual-sequence technique was used to acquire three myocardial slices and an arterial input function (AIF) image series. A proton-density weighted image was acquired at the beginning of each series. Fully quantitative perfusion pixel maps were generated by an automated processing ...
