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.

Vascular mapping using albumin-(Gd-DTPA), an intravascular MR contrast agent, and projection MR imaging.

An intravascular magnetic resonance (MR) contrast agent is valuable for vascular mapping of tissues when used in combination with projection spin-echo MR imaging. The primary advantage of using projection imaging lies in its global depiction of anatomy. Also, relatively short echo time values can be readily achieved, reducing flow dephasing signal losses from blood and increasing overall signal-to-noise. These advantages, coupled with the reduction of blood pool T1 values due to the presence of the intravascular contrast agent, allow for detailed spatial mapping of slow-flow vascular structures using MR.
