Accuracy of Image Diagnosis by Radiology Technologist for Cranial Computed Tomography

Abstract

Cranial computed tomography (CT) is replacing skull radiography in head trauma. Rapid diagnostic radiological opinions on these images may not always be available. The aim of this study was to determine the accuracy of radiology technologist image diagnosis in different cranial CT cases. A retrospective series of 30 cases was reviewed and interpreted by 20 radiology technologists, and the results compared with the diagnosis of radiologist as reference standard opinion. An overall accuracy of 77.34% was achieved, with a sensitivity of (95.89%) and specificity of (59.74%). The study also found that the accuracy affected by work experience period and peripheral image interpretation courses taken by the technologist. The results are not similar to studies of interpretation of other countries because of different style of education and job description for technologist. The study recommends that more formal educational subjects and courses in image interpretation for technologists and Appropriate training program.
