Computed Tomography (CT) is an essential diagnostic tool in medical imaging, offering high-resolution cross-sectional images for accurate disease diagnosis and treatment planning. In Ghana, diagnostic CT systems are becoming increasingly important in both public and private healthcare institutions. The performance of these systems is often influenced by factors such as equipment age, maintenance practices, and adherence to quality control standards. This study provides a comprehensive clinical performance assessment of six selected diagnostic CT systems across various healthcare facilities in Ghana.

The primary objective of this study is to evaluate the clinical performance and operational efficiency of six diagnostic CT machines in Ghana, examining parameters such as image quality, radiation dose, and overall equipment performance. The study aims to identify potential areas for improvement, ensuring optimal diagnostic outcomes for patients and enhancing equipment longevity through better maintenance practices.

Cross-sectional clinical performance assessment was conducted on six diagnostic CT equipment located in different hospitals across Ghana. The evaluation focused on key performance parameters, including image quality, radiation dose output, and equipment functionality. Testing protocols followed international standards set by the International Atomic Energy Agency (IAEA), and American College of Radiology (ACR). Data were collected using standardized phantoms, dosimeters, and quality control tools. The equipment was assessed for compliance with manufacturer specifications and international protection and safety guidelines.

All six CT machines evaluated in this study met the recommended clinical performance standards. The image quality across all devices was within acceptable ranges, demonstrating adequate contrast resolution, spatial resolution, and noise levels. Radiation dose outputs adhered to international protection and safety protocols, with all machines operating within the acceptable dose limits. The study also identified a lack of adherence to routine quality control testing in some facilities, which may contribute to reduced diagnostic accuracy and increased patient radiation dose.

The clinical performance of the six diagnostic CT equipment assessed in this study was found to be satisfactory, with all machines passing the performance evaluation. These findings indicate that the CT equipment in the selected facilities in Ghana is operating effectively and safely, contributing to the accurate diagnosis of patients. Regular performance assessments, such as this one, are essential to ensure the continued reliability and delivery of acceptable dose by the diagnostic imaging equipment.
