Three-dimensional computed tomography imaging: its applicability in the evaluation of extensor tendons in the hand and wrist.

Objective: The purpose of this study was to determine whether 3-dimensional (3D) computed tomography (CT) imaging with volume rendering can accurately evaluate extensor tendons in the hand and wrist.

Methods: Three-dimensional CT imaging was used to evaluate 14 cases. The location where the rupture was suspected was the wrist level in all cases.

Arteriovenous malformation of the ring finger. Pre- and postoperative evaluation using three-dimensional computed tomography angiography.

We experienced a case of arteriovenous malformation of the ring finger. The lesion was examined by three-dimensional computed tomography angiography with volume rendering and maximum intensity projection techniques pre- and postoperatively. The images demonstrated the location and extent of the lesion and were quite useful for surgical planning and the evaluation of operative results.
