Retrospective series reveals clear differentiation of intracranial hemorrhage, edema, and infarction in neurological patients, highlighting the diagnostic precision of early computerized tomography.

Key Points

To evaluate the diagnostic accuracy of the EMI scanner in detecting intracranial lesions and distinguishing diverse neuropathological conditions based on tissue X-ray absorption values.
Reviewed radiological findings from the first 650 consecutive patients undergoing brain examination with the EMI scanner.
Assessed differential tissue absorption values of X-ray photons to identify trauma, cerebrovascular accidents, hydrocephalus, and intracranial mass lesions.
High-absorption hematomas were clearly distinguished from low-absorption cerebral edema, enabling prompt differentiation between cerebral hemorrhage and infarction as early as eight hours post-event.
Tumors were detected in a high percentage of patients, though distinguishing tumor type from infarction, necrosis, or infection remained challenging, while ventricular anatomy in hydrocephalus and cerebral atrophy was readily mapped.
