OBJECTIVE: To prospectively evaluate the ability of dual-energy CT (DECT), compared with MRI, to identify @entity3814 in acute @entity130 @entity1 . METHODS: This institutional review board-approved study included 23 consecutive @entity1 with 32 @entity174 who underwent both DECT and MRI of the spine between February 2014 and September 2014. A total of 209 vertebrae were evaluated for the presence of abnormal bone marrow attenuation on DECT and signal on MRI by five experienced radiologists. The specificity, sensitivity, predictive values and intraobserver and interobserver agreements were calculated. RESULTS: MRI revealed a total of 47 vertebrae (22.4% of all vertebrae) and DECT revealed 44 vertebrae (21.0% of all vertebrae) with @entity4 . Using MRI as the reference standard, DECT had sensitivity, specificity, positive-predictive value, negative-predictive value and accuracy of 89.3, 98.7, 95.4, 96.9 and 96.6%, respectively. With respect to establishing the presence of @entity4 , the interobserver agreement was almost perfect (k   =   0.82), and the intraobserver agreement was substantial (k   =   0.80). CONCLUSION: Compared with MRI, DECT can provide an accurate demonstration of acute @entity174 and can be used as an alternative imaging modality for the assessment of @entity174 in @entity1 with contraindications for MRI. Advances in knowledge: Distinguishing of acute and chronic vertebral compression fracture is important for treatment choices. DECT is very fast compared with MRI and is an alternative imaging modality for the assessment of @entity174 in @entity1 with contraindications for MRI.
