Kesesuaian MRI 1,0 Tesla untuk Membedakan Spondilitis dan Metastasis Vertebra dengan Konfirmasi Hasil Histopatologi

Background: Magnetic Resonance Imaging (MRI) is the most accurate modality imaging to evaluate vertebral abnormality. Infection and metastatic in musculoskeletal is most commonly found in the vertebra. It is often difcult to di?erentiate between spondylitis and metastatic, both clinically and radiographically, mainly on atypical case.Objective: To analyze the precision of MRI 1,0 Tesla in di?erentiation of radiological imaging between spondylitis and vertebral metastatic with histopathological confrmation.Materials and methods: This is an analytic observational study, with cross-sectional research design. Statistical analysis was performed with Mc Neemar test. Samples were selected by consecutive sampling with 35 patients (15 men, 20 women), 22samples of spondylitis and 13 of samples metastatic which were confrmed by histopathological examination.Result: From 22 samples of spondylitis confrmed by histopathology, only 86% (19 samples) were diagnosed as having spondylitis on MRI, whereas 13 metastatic samples 100% was correctly diagnosed on MRI.Conclusion: Statistically there was no signifcant di?erences between radiology diagnostic using 1,0 Tesla MRI with histopathological diagnosis, p=0,250 (p> 0,05), with tendency MRI 1,0 Tesla is more precise in diagnosing metastatic. MR imagesshow typical fndings in spondylitis such as anterior component corpus vertebral and discus intervertebralis involvement, disk signal abnormalities, paravertebral abscesses and involvement of multiple vertebral bodies sequentially. MR images show typical fndings in metastasis such as anterior and posterior corpus vertebral involvement, paravertebral soft tissue mass and skip lesion.
