[Radiological differential diagnosis of rheumatoid arthritis].

CLINICAL/METHODICAL ISSUE: Establishing an early and reliable diagnosis of rheumatoid arthritis (RA) is of major importance but can be a great clinical challenge leading to direct therapeutic consequences. No single epidemiological, genetic, clinical, serological or radiological test exists which can exclusively diagnose RA.

STANDARD RADIOLOGICAL METHODS

In general diagnosis of RA includes a case history, clinical signs, laboratory abnormalities and radiological examinations, viz. conventional radiography of the joints of the hands and feet.

PRACTICAL RECOMMENDATIONS

This review summarizes the most important radiological features of RA and the radiological findings of its closest differential diagnoses.
