- Change in Emergency Department Length of Stay following Routine Adoption of Dual-Energy CT to Differentiate Intracranial Hemorrhage from Calcification
This retrospective study compared ED LOS over a 1-year period before and after implementing automated DECT processing in the evaluation of indeterminate intracranial hyperdensities. The authors showed that with intracranial indeterminate hyperdensities, there was a larger statistically significant difference in pre-DECT versus post-DECT ED LOS. The pre-DECT ED LOS correlated with increased frequency of neurosurgical consultation and repeat head CT.
- Evaluation of an Artificial Intelligence Model for Identification of Mass Effect and Vasogenic Edema on CT of the Head
This study compared the accuracy of a stand-alone AI model with consensus neuroradiologists’ interpretations in detecting mass effect and vasogenic edema on CT of the head. The ability to identify these findings could assist the clinical workflow through prioritizing the interpretation of abnormal cases.
- An Optimized CT Protocol for Detecting Suspected Cauda Equina Syndrome: A Comparative Analysis with MRI
This study prospectively evaluated the diagnostic accuracy of an optimized CT lumbar spine protocol as a potential alternative to MRI in assessing suspected neural compression. CT accurately identified all cases requiring urgent decompression. CT had 97% sensitivity, specificity, and positive and negative predictive values in detecting disc pathology in patients presenting with symptoms suggestive of acute neural compression compared with MRI.
