Fig. 2 — a) Axial DECT Iodine Map of the middle finger MCP joint from 28-year-old man with PsA demonstrates linear enhancement along the articular capsule, suggestive of capsular synovitis (arrowhead).

b) Axial section of cadaveric specimen shows capsular synovium as a circular structure (arrow) surrounding metacarpal head.

c) Corresponding axial PDWI delineates synovium that is in close relationship with metacarpal head.

d) DECT Iodine Map was obtained after application of diluted contrast medium on the inner articular capsule surface (arrow). Linear enhancement similar to the capsular synovitis of the case was delineated.
