Please take a look at this great website. It is full of excellent information.
This is a great example of MRI imaging of the wrist.

A coronal gradient echo image again depicts the erosion (red arrow), and a fleck of soft tissue calcification (yellow arrow):
Chien et al. described focal radiographic abnormalities of the radial styloid as a manifestation of de Quervain disease (AJR 177:1383-1386, 2001). Axial images from our patient:
(A) Axial T1 image depicts erosion in distal radius. (B) Axial T2 fatsat image shows inflammation surrounding the APL and EPB tendons (green arrow).
Chein et al. noted that “in the appropriate clinical context, radiographic visualization of focal cortical erosion, sclerosis, or periosteal bone apposition of the radial styloid should suggest the diagnosis of de Quervain tenosynovitis”. Although their report described the x-ray manifestations of de Quervain syndrome, the same findings can be depicted on MRI, as demonstrated in this case.
