"T1: low signal"
"T2: low signal"
"gradient echo (GRE) with T2* weighting: low signal"
"GRE T1-weighted in-phase and out-of-phase sequences: decreased signal on in-phase images compared to out-of-phase images (due to increased T2* effect on the in-phase images, which usually have longer echo times)"
