Ali IT, et al. - This study was designed to assess the utility of dual-energy CT (DECT) for assessing carpal fractures and to obtain an attenuation value cutoff (in Hounsfield units) to identify bone marrow edema due to an acute carpal fracture. In the setting of acute wrist fractures, DECT was identified to be a useful tool for identifying bone marrow edema, providing an alternative to MRI. For accurate diagnosis and exclusion of carpal fractures, a cutoff value of 5.90 HU can be used.
