  3. Abbreviations and clarifications • Ax = axial • Cor = coronal • Sag = sagittal • FOV = field of view • PD = proton density • TE = time to echo in milliseconds • FS = fat suppressed • Int = intermediate • Int FS: this is a fat suppressed sequence with a long TR and a TE between that of a traditional PD (e.g. TE= 10-20) and a traditional T2 (e.g. TE=80-100). The advantage of this sequence is that the TE is short enough to maintain sufficient signal for visualisation of the anatomy (like a PD) yet long enough to be more fluid sensitive (like a T2) • For STIR sequence, TI (inversion time) should be 140-150 at 1.5T

  4. SI joints / Sacrum • Patient in supine position as straight as possible • Coronal obliques parallel to sacral body, cover bone only - include L3/L4 disc space at top of FOV to bottom of coccyx • Axial obliques 90° to oblique coronal images - extend from L4/L5 disc space through end of coccyx • No contrast unless otherwise specified or if for sacroiliitis
