Figure 1.
Volumn-rendered three-dimensional dual-energy CT (DECT) image shows multiple monosodium urate deposits (i.e., tophi), which are responsible for this patient's symptoms as seen in both knees.
Figure 2.
Dual energy CT (DE-CT) images of uric acid deposits in various anatomical locations in both knees of the patent: (A) Lt Infrapatellar bursa, (B) Rt prepa-tellar bursa and semi-membrane-ous muscle, (C) Rt suprapatellar bursa, (D) Rt medial collateral ligament. With the application of the three material decomposition algorithm, uric acid deposits are depicted in green, whereas calc-ium in bone is depicted in blue. Multiple large subchondral and paraarticular bone erosions of both knee joints with severe joint space narrowing are found in each image.
