Hemorrhage Detection In Patients With Traumatic And Non-Traumatic Brain Injuries Through Multidetector Computed Tomography

Abstract

Background: Brain injuries, including traumatic brain injuries (TBI) and non-traumatic brain injuries (nTBI), are significant causes of morbidity and mortality worldwide. Intracranial hemorrhages, including subdural, epidural, subarachnoid, and intraparenchymal types, are critical complications that require prompt diagnosis. Multidetector computed tomography (MDCT) is a rapid and reliable imaging modality for detecting and assessing these hemorrhages in terms of type, volume, and location.

Objective: To evaluate the role of multidetector computed tomography in detecting types of hemorrhages and their anatomical region in traumatic and non-traumatic brain injuries.

Methods: A cross-sectional study was conducted from June 2025 to November 2025, including 67 patients (46 TBI, 21 nTBI) who underwent non-contrast MDCT scans of the brain. Data on hemorrhage type, region, volume, and patient demographics were collected using a self-structured proforma and analyzed with SPSS v27.

Results: Among the 67 patients, 68.7% had TBI and 31.3% had nTBI. Subdural hemorrhage was the most common type (58.2%), followed by intraparenchymal (22.4%), epidural (10.4%), and subarachnoid hemorrhages (9.0%). The most frequent hemorrhage volume ranged from 41–50 cc, and the left frontal lobe was the most commonly affected region (17.9%). The majority of cases were male (73.1%).

Conclusion: Subdural hemorrhage is the most prevalent intracranial hemorrhage in both TBI and nTBI patients, with the left frontal lobe being the most frequently involved region. MDCT provides a rapid and reliable means to assess hemorrhage type, volume, and location, which is critical for clinical decision-making. Further studies with larger sample sizes and multiple centers are recommended to enhance generalizability, especially for non-traumatic brain injuries.
