Abstract

‎ The aim of this review is to establish the correct diagnosis of malignant and benign compression ‎vertebral fractures by MRI to determine treatment and prognosis. ‎‎ Over 5 months period all the MRI examination of fractured vertebrae reported by the radiology ‎department at KHMC were reviewed. Data collected for examination include MRI conventional T1W, T2W ‎spin echo sequences and fast spin echo with STIR (short inversion recovery) sequences. All the cases ‎selected were given intravenous gadolinium contrast medium. Evaluation of the compressed vertebrae ‎includes children and adults, males and females of different ages.‎‎ Certain criteria are used to differentiate between benign and malignant collapsed vertebrae on MRI ‎based on the signal intensity, morphology and pattern of contrast enhancement for correct diagnosis. ‎‎ In conclusion, homogenous and diffuse abnormal signal intensity, posterior convexity and involvement ‎of the pedicles are signs that are strongly suggestive of malignant vertebral compression; conversely, a ‎band-like area of low signal intensity adjacent to the depressed endplate or preservation of signal ‎intensity of the vertebra suggests benign nature of the collapse.‎
