Table 1. Conventional and MASTIR sequences, mainly for sensitivity.

Sequence #	Sequences: conventional; MASTIR	Target tissues/fluids	Common TP changes	Purpose
I	T1W SE, MP-RAGE; SIR, rSIR	White or gray matter or both	↑ in T1	Sensitivity to increase in T1 in common disease in white or gray matter or both
II	T2W SE, T2-FLAIR; SIRES, rSIRES	White or gray matter or both	↑ in T1, and T2	Sensitivity to increase in T1 and T2 in common disease in white or gray matter or both
III	T2W SE, D, D* map; SIRDES	White or gray matter or both	↑ in T1, T2 and D*	Sensitivity to increase in T1, T2 and D* in common disease in white or gray matter or both
IV	T1W GE, T2W SE, T2-FLAIR pre and post contrast enhancement with Gd-DTPA; rSIR or rSIRES pre and post contrast enhancement with Gd-DTPA	White or gray matter or both	↓ in T1 in lesions post contrast	Demonstration of contrast enhancement due to Gd-DTPA

MASTIR, Multiplied, Added, Subtracted and/or FiTted; TP, tissue property; MP-RAGE, magnetization-prepared rapid gradient echo; SIR, subtracted inversion recovery; rSIR, reverse SIR; SE, spin echo; GE, gradient echo; FLAIR, FLuid Attenuated inversion recovery; SIRES, subtracted inversion recovery echo subtraction; rSIRES, reverse SIRES; SIRDES, subtracted inversion recovery diffusion echo diffusion subtraction.
