Abstract
In summary, the study included 30 patients with unilateral
painful wrist referred from the orthopedic surgeons requesting for CT
and MR arthrography. 25 cases done with single radiocarpal injection,
4 cases done by double injection (radio carpal and mid carpal) and a
single case done by single mid carpal injection.
We evaluated MDCT arthrography, and MR arthrography in the
diagnosis of tears and TFCC abnormalities of the wrist ligaments in a
series of patients.
CT and MR arthrography show perfect agreement in diagnosis of
abnormalities of wrist ligaments and TFCC especially in the diagnosis
of complete tears of the scapholunate and lunotriquetral ligaments.
MDCT arthrography, however, is superior in the diagnosis of
partial tears of the scapholunate and lunotriquetral ligaments.
MR arthrography is superior in diagnosis of early degenerative
changes of TFCC.
Because of perfect agreement between CT and MR arthrography
accuracy and reliability, we propose that examination with one
modality is usually diagnostic.
