Diffusion weighted MR imaging in acute vertebral compression fractures: differentiation between malignant and benign causes
AIM The primary objective of this study was to evaluate the specificity and sensitivity of diffusion weighted MR imaging (DWI) in the differentiation and characterisation between benign and malignant vertebral compression fractures compared with conventional T1 WI, T2 WI and fat suppressed contrast enhanced T1 WI in the Malaysian population. MATERIALS AND METHODS Thirty five patients with 68 ...
متن کاملCharacterization of benign and metastatic vertebral compression fractures with quantitative diffusion MR imaging.
BACKGROUND AND PURPOSE Conventional imaging techniques cannot be used to unambiguously and reliably differentiate malignant from benign vertebral compression fractures. Our hypothesis is that these malignant and benign vertebral lesions can be better distinguished on the basis of tissue apparent diffusion coefficients (ADCs). The purpose of this study was to test this hypothesis by using a quan...
متن کاملIn re: characterization of benign and metastatic vertebral compression fractures with quantitative diffusion MR imaging.
We enjoyed reading the recent article by Zhou et al (1) on the application of quantitative diffusion imaging to the differential diagnosis of benign versus metastatic vertebral compression fractures. This article and the accompanying editorial provided useful insights into both the clinical dilemma posed by this problem and the limitations of current MR imaging methodology in addressing it. As ...
متن کاملMalignant versus benign vertebral collapse: are new imaging techniques useful?
Benign and malignant vertebral collapse is common in the middle-aged and elderly population. Differential diagnosis sometimes remains difficult using radiographs, computed tomography (CT) and magnetic resonance imaging (MRI) if strong edema is present. Established morphological criteria and new methods such as positron emission tomography (PET)-CT and diffusion and perfusion MRI are helpful for...
متن کاملAcute vertebral compression fracture: differentiation of malignant and benign causes by diffusion weighted magnetic resonance imaging.
OBJECTIVE To evaluate the sensitivity, specificity and accuracy of diffusion weighted (DWI) magnetic resonance imaging (MRI) in the diagnosis and differentiation between benign (osteoporotic/infectious) and malignant vertebral compression fractures in comparison with histology findings and clinical follow up. METHODS The study was conducted at the Radiology Department, Aga Khan University Hos...
