Classification of Klauser et al for Wrist Tenosynovitis in Rheumatoid Arthritis Using Ultrasonography

Description

Klauser et al evaluated wrist tenosynovitis in rheumatoid arthritis (RA) using ultrasonography. He found that contrast-enhanced grey-scale ultrasound (CEUS) performed well for detecting vascularity. The authors are from Medical University Innsbruck in Austria.

Patient selection: wrist tenosynovitis

Ultrasonography: grey-scale and contrast-enhanced grey-scale

Parameters:

(1) synovial thickness in mm on grey-scale US

(2) extent of vascularity in axial scanning plane on CEUS

(3) peri- and intra-tendinous vessel detection on CEUS

(4) intensity of peri- and extra-tendinous vasculity and CEUS

Parameter	Finding	Points
synovial thickness in mm	< 2 mm	0
	2 – 4 mm	1
	> 4 mm	2
extent of vascularity	none	0
	< 50% of peritendinous synovial proliferation	1
	>= 50% of peritendinous synovial proliferation	2
peri- and intra-tendinous vessel detection	none	0
	only peritendinous	1
	per- and intra-tendinous	2
intensity of peri- and extra-tendinous vascularity	none	0
	peri less than extra	1
	peri greater than or equal to extra	2

Interpretation:

• minimum grading: all 4 parameters Grade 0

• maximum grading: all 4 paramters Grade 2

• The more severe the vascularity the more severe the rheumatoid arthritis.
