Information provided by different MRI sequences.

Sequence	Abbreviation	Comments
T 1 weighted Spin Echo	T1wSE	Fracture lines can be visible as linear low signal against higher signal bone marrow. Poor for assessing cartilage surface [48].
T2 weighted Turbo Spin Echo with Fat suppression	T2wTSE FS	Allows sharper contrast between relative higher signal cartilage and lower signal bone marrow [51].
Short Tau Inversion Recovery	STIR	High sensitivity for edema [43]. Fluid is bright signal allowing demonstration of defects in cartilage. Less effective in thinner cartilage (talus) [43].
