## Indications for use
The Quantitative MT Analysis option on the EasyVision is intended for use in quantifying the Magnetization Transfer in tissue. The ratio image enhances the image contrast of MT sensitive tissue by the elimination of the T1 and T2 (spin-lattice and spin-spin relaxation time) effect. Visualization of Magnetization Transfer effects in sensitive tissue can improve lesion conspicuity, e.g., in white matter and cartilage.
