Three-Dimensional Phase-Sensitive Inversion-Recovery Turbo FLASH Sequence for the Assessment of Left Ventricular Myocardial Scar in Swine
OBJECTIVES We sought to evaluate the feasibility and accuracy of free-breathing three-dimensional (3D) phase-sensitive inversion-recovery (PSIR) Turbo FLASH sequence for noninvasive assessment of left ventricular myocardial scar in swine models. MATERIALS AND METHODS Nine Chinese minipigs with experimentally induced acute myocardial infarction were studied. At 1 week and the study endpoint 4 ...
متن کاملDetection of hepatocellular carcinoma: Comparison of in-phase and out-of-phase gradient recalled echo dynamic MR imaging using double-echo FLASH sequence during the hepatic arterial phase
Introduction MR imaging with Tl-weighted gradient recalled echo (GRE) pulse sequences during the hepatic arterial phase of contrast enhancement techniques provides better liver lesion detection and characterization particularly for detection of hypervascular liver neoplasms. However, the shortest TE available on GRE pulse sequence is occasionally at the opposed-phase TE, at which images can be ...
متن کاملPhase offset estimation using enhanced turbo decoders
This paper discusses a realistic turbo coding system with the signal phase which has not been perfectly estimated. We propose improved decoding algorithms for the situations when the residual phase error can be modelled by the Gaussian probability distribution and a Markov chain, a model which can be used in many actual phase estimators. It is shown that increasing the state space of the decode...
متن کاملDetection of hepatocellular carcinoma using double-echo FLASH sequence during the hepatic arterial phase.
PURPOSE The purpose of this study was to compare the performance of in-phase and opposed-phase gradient-recalled echo (GRE) pulse sequences in paramagnetic contrast-enhanced magnetic resonance (MR) imaging of hepatocellular carcinomas (HCCs) during the hepatic arterial phase. MATERIAL AND METHODS Thirty-four patients with 84 lesions with known or suspected HCCs, nine of whom had a fatty liver...
متن کاملeffect of flip angle on the correlation between signal intensity and different concentrations of iron oxide nanoparticles using t1-weighted turbo-flash inversion recovery sequence
results the maximum si was obtained at the highest applied flip angle (45°). the linear relationship between si and nanoparticle concentration was seen up to 112.21 and 98.83 μmol fe/l for the short (10°) and the long (45°) flip angles, respectively (r2 = 0.95). these values were reduced up to 48.54 and 42.73 μmol fe/l for these flip angles with r2 of 0.99. conclusions the maximum si will be in...
