| Abstract | ||
| Background: the basal ganglia are part of the extrapyramidal motor system, participating in the production of movement, but they are also involved in memory, emotion, and other cognitive functions. Objective: This work aimed to study the role of multidetector computerized tomography versus magnetic resonance imaging in diagnosis of basal ganglia signal intensity alteration with highlight on accuracy, sensitivity, specificity of each tool in reaching the proper diagnosis. Patients and Methods: this study was designed to examine the effectiveness of both computed tomography and magnetic resonance imaging in diagnosis of different basal ganglia lesions. It included 50 patients, selected from Al-Azhar University hospital. Results: sensitivity of CT in diagnosis of basal ganglia lesion was 86.0%, and failed to elicit diagnosis in 14.0% of patients. There was no significant difference between males and females. MRI sensitivity in diagnosis of basal ganglia lesions was 92%, while it was unable to diagnose 4.0%. There was no significant difference between males and females (the sensitivity in males was 94.7% and in females, it was 83.3%). Conclusion: MRI is superior to CT for diagnosis of different basal ganglia lesions, except for senile calcification, where CT was superior to MRI. However, CT presents a considerable sensitivity. Thus, it is advisable to start with CT examination to avoid high cost of MRI, otherwise start with MRI when the cost is not a matter or the condition is not in an emergency situation. In such emergent situations, MRI must be used as a first choice. | ||
