Purpose: The aim of this study was to determine to what extent we could identify the metabolism product peak using 3-T proton magnetic resonance spectroscopic imaging (MRSI) of the prostate gland in healthy volunteers by combining an external array coil with Malcolm Levitt composite-pulse decoupling sequence (MLEV)-point-resolved spatially localized spectroscopy (PRESS).
Materials And Methods: MRSI data were obtained from the entire prostate gland in six healthy volunteers. The heights of the choline, citrate peaks and the standard deviation (SD) of the noise in each voxel were calculated.
Article Synopsis
- Sentinel lymph node biopsy (SLNB) is crucial for detecting breast cancer spread to lymph nodes, but false negatives are a concern.
- Equivalent cross-relaxation rate imaging (ECRI) can assess lymph node structure changes via MRI and may help improve SLNB accuracy by distinguishing between metastasized and non-metastasized regions.
- ECRI findings indicated that non-metastatic regions had higher ECR values compared to metastatic ones, suggesting it could enhance the effectiveness of SLNB.
We evaluated the usefulness of two-dimensional time-of-flight (2D TOF) MR venography (MRV) of the lower extremity using the respiratory compensation (RC) technique. In addition, six variations in patient positioning of the leg and knee were investigated to determine the best method of visualizing the deep popliteal veins and lower leg. All data sets were reviewed and graded for visualization of the deep veins at the pelvis, thigh, and leg portion (4-point scale) by two radiologists and three radiological technologists.
