Stereoscopic MR imaging.
The visual fusion of two projection or slice-selective magnetic resonance (MR) images taken at two oblique angles imparts three-dimensional (3D) information within the projection or slice. This approach to 3D MR is rapid and straightforward, requiring only two oblique images and, at most, only a simple optical stereoscope for viewing. Stereoscopic images of the vascular system of a rat were obtained using the intravascular contrast agent albumin-(Gd-diethylenetriaminepentaacetic acid). Stereoscopic images of the human head showing CSF distribution were acquired using a long echo time sequence. These images illustrate the potential clinical applications of this technique.
