Indications

• Suspected inguinal canal hernia
• Anterior groin pain / inner thigh pain
• Sports injury to anterior groin / pelvic ring
• Symphysis pubis pathologies
• Sports hernia / Adductor origin injury

Positioning

• Supine centred on MR couch

Scan

• Low centered pelvis and upper thighs

Sequence	Comments
PDFS Axial	Inguinal canals and upper thighs
T1 Coronal	Standard pelvic coronal plane, centre on symphysis pubis
STIR Coronal	As above, lower centring than usual hip scan
PDFS Coronal Oblique	Angled to pelvic outlet
PDFS Sagittal	Cover hip to hip, crossing symphysis pubis as centre point (middle of FOV)

Challenges

• Tilting correctly for the Coronal Oblique is best achieved with a sagittal planning sequence to take an angle between the ASIS and the symphysis pubis
• Region of interest is different to normal hip scan. Make sure that the symphysis pubis is the centre point level for ML and CC FOV. Ensure that some of the upper thigh is included in the scan to judge muscle sprain, especially on the sagittal image
