Soft tissue changes in early rheumatoid arthritis as seen on xeroradiography and non-screen radiographs. 1978

P W Verow, and J Dippy

Forty-seven patients with early or newly established rheumatoid arthritis were studied with non-screen radiography and xerography. Estimations of soft tissue swelling, bone erosion and cysts were made by two observers and the results compared between observers and the two types of imaging. The results indicate no significant advantage or disadvantage in xerographic imaging compared with non-screen radiographs in the identification of superficial soft tissue swelling and bone erosions. More cysts were, however, identified on the radiographs. In a previous anatomical study of the dissected hand, xerography showed definite advantages in the detection of certain features.

D001172	Arthritis, Rheumatoid	A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.	Rheumatoid Arthritis
D013581	Synovial Cyst	Non-neoplastic tumor-like lesions at joints, developed from the SYNOVIAL MEMBRANE of a joint through the JOINT CAPSULE into the periarticular tissues. They are filled with SYNOVIAL FLUID with a smooth and translucent appearance. A synovial cyst can develop from any joint, but most commonly at the back of the knee, where it is known as POPLITEAL CYST.	Synovial Cysts,Cyst, Synovial,Cysts, Synovial
D014955	Wrist Joint	The joint that is formed by the distal end of the RADIUS, the articular disc of the distal radioulnar joint, and the proximal row of CARPAL BONES; (SCAPHOID BONE; LUNATE BONE; triquetral bone).	Joint, Wrist,Joints, Wrist,Wrist Joints
D014986	Xeroradiography	A photoelectric method of recording an X-ray image on a coated metal plate, using low-energy photon beams, long exposure time and dry chemical developers.	Xeroradiographies
