SHR-CTA of the hand (with GI) in a 69-year-old woman that shows the complex arterial network of the hand with a Type A incomplete SPA. The UA (1) feeds the ulnar side of the SPA (2), while the superficial branch of the RA feeds the radial side of the SPA (3). The SPA gives off branches into the first web space, which supply the radial side of the index finger and the thumb (4). The DPA (5) is constituted mainly from the RA (6), which forms an anastomosis with the deep branch of the UA. It generates the FPMA (7). Note the close relationship between the UA and the hamulus. Note also carpal degenerative changes and joint calcifications due to calcium pyrophosphate deposition disease
