We evaluated radionuclide cisternography for the diagnosis of intracranial hypotension in terms of the rate of appearance of abnormal findings in 23 patients, their correlation with therapy, and the most suitable scanning method and timing for visualization of leakage. During the first hour after injection, dynamic lumbar images or consecutively re...
In comparison with thin-section source images, MPR images are comparably sensitive but not as specific for the detection of findings. When producing MPR images, the slice thickness of source images should be less than 2 mm.
These results suggest that a high signal intensity area on T2-weighted images is a marker of severe facial nerve damage. FLAIR imaging is useful for identification of T2-prolongation in the distal intrameatal segment.
Cystic structures near the frontal horns in neonates are detected by MRI at a rate of 4.8%. They will resolve spontaneously without causing developmental abnormalities.
High-spatial-resolution MRI using the VIBE sequence is more accurate for the detection and evaluation of the extent of DCIS than MDCT. In dynamic studies, more accurate evaluation of the extent of DCIS is possible in late-phase images.
