Abstract
Introduction: Computed tomography is in clinical practice of utmost important for differentiating stroke from other diseases, which may mimic stroke, it also distinguishes one type of stroke from other.The purpose of this study is to document the presence or absence of hemorrhage or infarcts, to find the location and reasonably assess the blood vessels involved and to spot the incidence of negative cases of clinically suspected stroke.Materials and Methods: Detailed clinical history was taken in patients admittedinourhospital as per the Proforma. All patients referred for CT evaluation were scanned by using GE Hi speed dual slice spiral CT scanner and Toshiba helical CT scanner machine with the following specifications: 80 milliamperage, 120 kilovoltage, tilting angle ±22o, matrix size of 512×512. Scans are taken parallel to the floor of the anterior fossa, the lowest section through the external auditory meatus and continuing to the top of the head. The gantry is angled towards the feet. Slice thickness of 4mm was used for scanning posterior fossa, 7mm for remainder of the head and wherever necessary still thinner sections weretaken.
Results: 75 cases were turned out to be intracerebral haemorrhage, which accounts for 26.7%.10 cases of CVT and the percentage calculation was 3.5%. Tumors deterred in 10 cases out of 280 cases of suspected CVA, which accounts for 3.5% of the total study and SDH cases were also 3.5%. 7.1 % cases were found normal in evaluation.
Conclusion: CT scanning is very useful and life caring technique for diagnosis of acute stroke as the rational management of stroke.
