MRI of tenosynovitis in 4-year-old girl

Case Study
Chung, Taylor, M.D. Children’s Hospital & Research Center Oakland • USA

Patient history

4-year-old girl with suspected idiopathic inflammatory arthritis and wrist pain underwent an MRI scan at Children’s Hospital & Research Center Oakland (CHRCO, Oakland, California, USA).

MR examination

The MRI examination was performed on Achieva 3.0T using mDIXON TSE.


 T1W TSE SPIR <br><br. mDIXON water <br><br>
mDIXON water

The T2W TSE with SPIR fat suppression shows high signal intensity in the marrow of the proximal phalanx of the thumb and adjacent soft tissue medially. This high intensity proved to be due to inhomogeneous fat suppression, as on the mDIXON water image no increased signal intensity is seen in the same regions. Abnormal high signal intensity tissue is seen surrounding the flexor tendons, which showed contrast enhancement on the T1W images (not shown)


MRI confirms significant tenosynovitis around the flexor tendons in her hand.

Clinical impact

The most significant benefit of mDIXON TSE is the robust fat and water separation. This allows to shorten the exam time, which is of great impact on pediatric patients who are prone to movement.
