Nuclear angiography is widely used for a dynamic assessment of vascular alteration in rheumatoid arthritis, especially in the early stage (Hopfner et al. 2002, 2004). As in any inflammatory or infective diseases of the skeleton, nuclear angiography provides unique information on the disease activity of rheumatoid arthritis using visual or quantitative analysis of the blood flow, blood pool, and tracer uptake

both in the articular bones and the periarticu-lar soft-tissue structures. Actually, synovitis with pannus is an ideal target of nuclear angi-ography since the synovial interface with the cartilage and bone is the primary "attack zone" for rheumatoid arthritis (Feldmann et al. 1990; de Bois et al. 1995).

Pathologically, synovial hypertrophy occurs following edema and blood vessel proliferation due to the coordinated action of vascular and cellular responses during the first weeks of rheumatoid arthritis (Cotran et al. 1989; Stevens et al. 1991). Indeed, nuclear angiography shows increased blood flow to and blood pool in the inflamed synovium and chondro-osse-ous zone on rheumatoid joints (Fig. 10.50A). The tips of the fingers may become flushed with increased blood flow. Such vasodilatation could be related to systemic microcirculatory compromise that has been known to occur in rheumatoid arthritis (Rothschild and Masi 1982), and more specifically to endothelial dysfunction (Vaudo et al. 2004). The equilibrium phase (static) bone scan reveals increased tra cer uptake in inflamed focus of rheumatoid arthritis (Fig. 10.50B).

Osteoarthritis

Thank you for deciding to learn more about the disorder, Osteoarthritis. Inside these pages, you will learn what it is, who is most at risk for developing it, what causes it, and some treatment plans to help those that do have it feel better. While there is no definitive “cure” for Osteoarthritis, there are ways in which individuals can improve their quality of life and change the discomfort level to one that can be tolerated on a daily basis.
