Explanation of medical terms

Anterior = in front

Apophyseal joints = small genuine synovial joints between the vertebrae posteriorly

Biopsy = tissue sample

Cervical spine = neck (spine)

Costo-vertebral joints = joints between the vertebral bodies and the ribs

CT = computer tomography

Differential diagnoses = disease which can simulate sacroiliitis or spinal spondarthropathy

Extremities = limbs

Enteropatisk arthropathy = arthritis associated with inflammatory bowel disease

Entheses = attachment of capsules and tendons to bone

Erosion = demarcated joint facet defect due to tissue destruction as part of the disease process

Gadolineum (Gd.) = MRI contrast agent

Contrast enhancement = increased blood flow detected by contrast agent

Hyperostosis = enlargement of bone/joint region

Lateral view = view form the side

Lumbar spine = lower back

Lumbal region = lower back region

Monitor = watch

MR = magnetic resonance

MR-scanning = magnetic resonance scanning

MRI = magnetic resonance imaging

OMERACT = Outcome Measures in Rheumatoid Arthritis Clinical Trials

Osteoporosis = decreased bone density

Posterior = at the back

Psoriatic arthropathy = arthritis associated with the skin disease psoriasis

Pustulotic arthro-osteitis = rheumatic disorder associated with skin disease in the palm of the hand and/or sole of the foot (pustulosis palmoplantaris)

Reactive arthritis = arthritis elicited by an infection somewhere else in the body

Spine deformity = pathological change of the back curves

Sacroiliac joints = joints between the sacrum and the hip bones

Sacroiliitis = inflammatory changes in the sacroiliac joints

Sequence = MR recording mode

Seronegative spondyloarthropathy = inflammatory disorder predominantly involving the sacroiliac and spinal joints

Sclerosis = increased bone density

Scout view = initial fast MR sequence to be used for planning the slice orientation

SpA = seronegative spondyloarthropathy

Spine = back

STIR (Short Tau Inversion Recovery) sequence = MR recording mode

Structural changes = permanent damage

T1 FS = MR recording mode

Tl-weighted sequence = MR recording mode

T1-weighted fat-suppressed (T1 FS) sequence = MR recording mode

T2-weighted fat-suppressed sequence = MR recording mode

Trabecular bone = osseous structure inside a bone

Vascularised = containing blood vessels

Vertebral column = spine
