EŠect of Muscular Contraction on Magnetization Transfer Detected at 1.5T
نویسنده
چکیده
The eŠect of rigor (formation of actomyosin complexes) on magnetization transfer was observed with a 1.5T clinical magnetic resonance (MR) imaging system. The magnetization transfer ratio of chemically skinned (calcium-sensitive) muscle ˆber preparations increased much more in a rigor state than in a relaxed state, while that of calcium-insensitive ˆber preparations and solutions showed no diŠerence. These results suggest that the formation of actomyosin complexes increased the magnetization transfer ratio. A clinical MR system is not only eŠective for medical imaging, but also has the potential to demonstrate physiological characteristics.

Visualization of neuromelanin in the Substantia nigra and locus ceruleus at 1.5T using a 3D-gradient echo sequence with magnetization transfer contrast.
Recent technical advances have enabled the visualization of neuromelanin in the substantia nigra pars compacta (SNc) and locus ceruleus (LC) by 3-tesla (T) magnetic resonance imaging in vivo. In the present study, we successfully detected neuromelanin in the SNc and LC of 6 healthy volunteers at 1.5T using a 3D gradient echo sequence with off-resonance magnetization transfer contrast.

متن کاملAnalysis of Magnetization Transfer Ratio Measurements at 3T Using Multiple-Acquisition Balanced SSFP
Introduction. Magnetization transfer (MT) has become an important tool to study various tissue abnormalities, such as demyelination in brain white matter [1]. Recently, it has been shown that fast MT scans based on balanced steady-state free precession (bSSFP) with RF pulse modification achieve high SNR and high reproducibility at 1.5T [2]. At 3T, combination of multiple, phase-cycled, bSSFP sc...

The objective of this study was to investigate the efficacy of using quantitative magnetic resonance imaging (MRI) as a non-invasive tool for the monitoring of gene therapy for muscular dystrophy. The clinical investigations for this family of diseases often involve surgical biopsy which limits the amount of information that can be obtained due to the invasive nature of the procedure. Thus, oth...

INTRODUCTION Creating contrast between normal anatomy and pathology is the main goal of imaging. Here we compare contrast ratios of enhancing brain lesions at 1.5T between T1 TSE, magnetization prepared rapid gradient echo (MPRAGE) and subtraction and at 3T between T1 FLAIR, MPRAGE and subtraction. METHODS Contrast ratio between enhancing lesions and normal contralateral brain was measured fo...
