Abstract
The present work included 100 patients with history of acute head trauma and showing positive findings in coronal reformations in the NECT. They were 79 males and 21 females. Their ages ranged between 1 month and 70 years.
The aim of this study was to assess the value of the coronal reformations in multi-detector computed tomographic evaluation of acute head trauma.
All patients were examined using 6 multi-detector CT scanners (Siemens’ Emotion 6). The scan parameters used were 130kVp and ≤ 240mA per slice; tube rotation 0.75s and slice thickness 1 mm; lower doses (60-120 mA) were used with pediatric and small patients or those receiving or expected to receive serial scans.
The lesions were divided to fifty two patients presented with parenchymal brain contusions (52%), forty seven patients had skull fractures (47%), forty tow patients had extra axial hemorrhages (42%) and fourteen patients had subarachnoid hemorrhage (14%).
MDCT was successful in adequate characterization of the extent and type of the hemorrhage and skull fractures in cases of acute head trauma.
The coronal reformation added more informations to the routine axial images alone in 38 instancespatients (38%) out of the total number of 100 patients.
Among the 52 patients (52% of patients) with hemorrhagic brain contusions; coronal reformations showed better demonstration of the contusions in 17 patients (32.7% of patients with hemorrhagic contusions and 17% of all patients); these lesions encountered in areas adjacent the bone like lower part of the anterior cranial fossa, the vertex and temporal lobe as these areas are being adjacent to the frontal, ethmoidal, sphenoid and the high parts of the parietal bones.
In patients with skull fracture (47 patients with 47% of all patients); the coronal reformation images showed better demonstration of type of fracture and extension of the fracture in 13 patients (27.7% of patients with skull fracture and 13% of all patients) either in combination with the axial images or alone specially in fractures of temporal bone, the high part of the parietal bone (the vertex) and in the floor of the skull.
In patients with extra axial hemorrhages (42 patients with 42% of all patients including 25 patients with sub dural hemorrhage and 17 patients with epidural hemorrhage); the coronal reformations added more diagnostic value in 8 patients (19% of patients with extra axial hemorrhages and 8% of all patients) where the coronal images showed better demonstration of hemorrhages in areas near bone artifacts like the vertex or near the inferior surface of anterior, middle and posterior cranial fossae.
MDCT with coronal reformations should be considered in the diagnosis of brain hemorrhages or skull fractures in cases of acute head trauma.
