WebSTIR (as well as other short and medium-TI sequences) has an additional useful feature — additive T1+T2 contrast. In routine SE imaging lesions with prolonged T1 and T2 have competitive effects on signal intensity (↑T1 reduces signal while ↑T2 increases signal). In STIR imaging the effects of ↑T1 and ↑T2 are additive.
