The Quantitative MT Analysis option on the Easy Vision 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.

The Quantitative MT Analysis option uses MTC images created by an MR system and transferred to the EasyVision. The image contrast can be changed by calculating the ratio (based on (MT image- non-MT image)/MT image)) of the scans with and without the MT effect. The resultant image represents the percentile MT effect. The image contrast therefore becomes independent of the T1 (spin-lattice) and T2 (spin-spin) relaxation times and is defined by the MT effect alone.
