VALUE OF CONVENTIONAL SKULL X-RAYS EXAMINATION IN THE EVALUATION OF PATIENTS WITH SPACE OCCUPYING LESIONS AGAINST COMPUTED TOMOGRAPHY IN NIGERIA
Main Article Content
Abstract
Background: Today, patients would like to know about their diseases and diagnostic/treatment choices available to aid their medical care.
Purpose: To assess the value of conventional skull x-ray examination in the evaluation of patients with intracranial space occupying lesion (SOL) in comparison with Computed Tomography brain scan.
Materials and Methods: A total of three hundred and forty four (344) radiographs and seventy two (72) scanograms were used. Radiographs of the skull which queried intra-cranial space occupying lesions, with good contrast and well demonstrated structures as well as an accompanying radiologists report were assessed for contribution to diagnosis, views for detailed information, cost-effectiveness and patient care/management. Findings were compared to computed tomography images of patients with the same conditions.
Results: The result showed that the contribution of skull x-ray for patients with suspected (SOL) was 48.55% as against 68.06% for CT scan. Lateral view had 51.50% as a better view against postero-anterior (PA) and other views showing 28.14% and 20.36% respectively.
Conclusion: This study showed that conventional skull x-ray should be supplemented by CT scan and other imaging modalities especially in developing countries like Nigeria. This is due to their non-availability and may be affordability by a large number of the populaces.
