MRI Wrist - Coronal T1 - Scaphoid fracture
- Clinically this patient had a suspected scaphoid fracture which was not visible on the plain X-ray images
- This T1 image (fat is bright) shows reduced fat signal within the scaphoid – compare with the normal bone marrow in the other bones such as the adjacent capitate

MRI Wrist - Coronal STIR - Scaphoid fracture
- This STIR image (highly water sensitive) shows increased signal which correlates with the area of low signal seen on the T1-weighted image
- Signal is normal in the bone marrow of the other bones such as the capitate
- This pattern of altered signal represents bone marrow oedema due to bone bruising – typical features of an undisplaced scaphoid fracture
