“…A reason for this could be that PD performs better from the dorsal side of the joint than from the palmar side [19]. It was also important to consider standardization of gain settings and avoidance of unnecessary probe pressure and ensure complete relaxation of part under evaluation to avoid masking the Doppler activity [20].…”

Background Musculoskeletal ultrasound can be now considered a complement to physical examination in rheumatoid arthritis. This study evaluates the role of musculoskeletal ultrasound in assessment of rheumatoid hand function and underlying functional defects and disabilities in order to find out a possibly better tool for assessment. Results Hand grip weakness was significantly associated with metacarpophalangeal joints synovitis of ulnar 4 fingers (p = 0.045), wrist joint synovitis (p = 0.009), flexor tendons tenosynovitis of the ulnar 4 fingers (p = 0.001), flexor pollicis longus tendon tenosynovitis (p = 0.013). Hand function impairment by grip ability test was significantly associated with metacarpophalangeal joints synovitis of ulnar 4 fingers (p = 0.009), wrist joint synovitis (p = 0.004), and flexor tendons tenosynovitis of the ulnar 4 fingers (p = 0.042). Multiple linear regression analysis showed that the most influencing factor affecting grip ability test and hand grip strength was ulnar 4 Flexor tendons tenosynovitis (P = 0.023, P = 0.037) respectively. Conclusions Joint synovitis and tenosynovitis that are detected by musculoskeletal ultrasound can be used as an assessment tool for hand function in rheumatoid arthritis, since they are associated with reduced hand grip strength and impaired hand ability.

“…In the last decade, Power Doppler (PD) has been favored over color Doppler (CD) due to its increased sensitivity to weak flow and its ability to detect flow in all directions, even continuous flow in a looped vessel. 14 An innovative Doppler technique, superb microvascular imaging (SMI), provides visualization of microvascular flow with suppression of noise caused by motion artifacts using an innovative multidimensional filter system. This works without removing the weak signal arising from small vessel flow, achieving significantly greater sensitivity than PD.…”

The ankle and foot have numerous bones and complex joints that can be affected by several types of inflammatory arthritis with different patterns and various radiologic signs, depending on the phase of the disease. Involvement of these joints is most frequently seen in peripheral spondyloarthritis and rheumatoid arthritis in adults and juvenile idiopathic arthritis in children. Although radiographs are a mainstay in the diagnostic process, ultrasonography and especially magnetic resonance imaging allow early diagnosis and are crucial diagnostic tools. Some diseases have typical features based on target populations (e.g., adults versus children, men versus women), but others may have overlapping imaging characteristics. We highlight key diagnostic features and describe appropriate investigations to guide clinicians toward the correct diagnosis and provide support during disease monitoring.
