CDUS imaging may be used as an objective tool for assessing disease severity in Takayasu's arteritis. Development of a CDUS-K scoring system would be a supplementary tool to clinical scoring and the ITAS. CDUS imaging could be a cost-effective, non-invasive and reliable substitute for angiogram, especially for follow-up in Takayasu's arteritis patients.
Giant cell arteritis (GCA) is characterized by chronic granulomatous inflammation of medium and large arteries with predilection for extra-cranial branches of the carotid arteries. GCA is considered as the most common type of primary vasculitis in the Western world; however, it is reported less frequently from the Indian subcontinent. 1,2 Ultrasonographic evaluation of superficial temporal arteries (STA) is becoming a common practice in the diagnosis of GCA because it
Three or more flow signals and a RI ≤0.605 can be applied as USG criteria for sacroiliitis. USG can be a cost-effective and non-inferior modality compared with MRI in documenting sacroiliitis in early SpA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
