Mandatory medical device diagnostics.
- Radiographic examination of the spine (pelvis or targeted imaging of the sacroiliac joints) – to examine bony changes in axial spondyloarthritis (axSpA) [gold standard in detecting chronic structural changes in patients with axial spondyloarthritis (axSpA) or suspected axSpA].
- Magnetic resonance imaging (MRI; computer-assisted cross-sectional imaging (using magnetic fields, that is, without X-rays)) of the spine (spinal MRI) – Indications:
- Detection of inflammatory changes and fatty degeneration [standard method].
- Diagnosis or in the course
- Computed tomography (CT; sectional imaging procedure (X-ray images from different directions with computer-based analysis)) of the spine (spinal CT) – indications:
- Examination of bony change in axial spondyloarthritis (axSpA).
- Diagnosis or in the course
Optional medical device diagnostics – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.
- Electrocardiogram (ECG; recording of the electrical activities of the heart muscle).
- Echocardiography (echo; cardiac ultrasound) – if cardiac involvement is suspected.
- Abdominal sonography (ultrasound examination of the abdominal organs) – if renal involvement is suspected.
