WebMar 22, 2005 · Magnetisation transfer ratio (MTR) is increasingly used to evaluate neurological disorders, especially those involving demyelination. It shows promise as a surrogate marker of disease progression in treatment trials in multiple sclerosis (MS) but the value measured is highly dependant on pulse sequence parameters, making it hard to … WebThis is particularly advantageous in high resolution imaging or in performing fast scans on claustrophobic or moving patients. For example, a T1 tse sequence with matrix size of 320x320 and number of excitations (NEX) 2 with 100% SNR will take approximately 5 minutes in a 1.5T scanner.
