Dual-energy CT (DECT) and ultrasound are both comparable for detecting gouty arthritis, according to results from a new study. DECT is a new noninvasive imaging technique that allows direct visualization of uric acid crystal deposits and bone structures. Both imaging methods were performed across 37 joints in 21 patients suspected of having acute or chronic gout. DECT and ultrasound findings correlated in 32 of 37 joints (P <0.001), although ultrasound findings correlated slightly better than DECT with results from synovial fluid aspiration. DECT can diagnose gout in some locations where ultrasound is limited and can also differentiate between pseudogout and gout. However, ultrasound is more cost effective than DECT and does not expose patients to radiation. The authors conclude that DECT has a high sensitivity for detecting crystal deposits and is a promising tool for the early diagnosis of gout.
