It is well known that early detection of synovitis and tenosynovitis is of great importance in arthritis imaging studies, and early treatment can prevent irreversible bone and joint destruction, help preserve joint function and improve patients' quality of life

Current diagnostic criteria for arthritis include musculoskeletal ultrasound (MSUS) and magnetic resonance imaging (MRI)

So far, dual-energy CT (DECT) has developed into an important imaging tool for the diagnosis of gouty arthritis, and CT-subtraction (CT-S) and DECT-derived iodine map (iMap) can detect active soft tissue inflammation in joints uptake of contrast media with sufficient diagnostic accuracy

A study published in the journal European Radiology used two techniques, iMap and CT-S, to assess synovitis and tenosynovitis in patients suspected of rheumatoid arthritis of the hand and compared it with MRI using MSUS as the reference standard.

This prospective study evaluated arthritis patients at our institution

A total of 33 patients were included in the study

This study demonstrates that CT-S and iMap enable highly standardized imaging of arthritis and are suitable for clinical practice
