[Utility of the 3D GRE method in the female pelvic area with 3T MRI].
A high signal-to-noise ratio (SNR) can be obtained in three-Tesla (3T) MRI, and it is possible to use it to shorten imaging time and improve spatial resolution. However, reports of its disadvantages have been increasing. We attempted to describe a high-resolution evaluation image that made the best use of a decrease in SAR and high SNR by using the LAVA (liver acquisition with volume acceleration) method, a kind of three-dimensional GRE (3D gradient echo) method that did not show the above-mentioned disadvantage in obtaining a shadow inspection of the female pelvic area with 3T MRI. A 0.8 mm isovoxel image of excellent SNR could be obtained within about one and one-half minutes by using the LAVA method as a result of the examination. Moreover, a SAR that was problematic with the 3T MR device was able to be decreased, and was useful.
