Abstract :

Background: Quality control tests for computed tomography (CT) scanners are primarily concerned with the maintenance of CT scanner at the optimum operational condition. Aims of the study: The study aims at evaluating the CT number for water, field uniformity and noise for diagnostics CT scanners in Kano metropolis. Methods and Materials: Cross–sectional design was employed in the study. Using purposive sampling technique two centres were selected, one government hospital and one private radio–diagnostics centre. The phantoms used for the experiments were head CT water phantom and regions of interest were measured at centre of the image of the scan phantom and four other regions at the periphery of the images. Results: The mean CT number for water for Toshiba 162 slices was found to be 1.7 and standard deviation of 7.2, for GE 4 slices scanner was 0.1 and standard deviation of 2.28. Mean CT number for GE 16 slices scanners was found to be 1.58 and standard deviation of 9.77. Conclusion: Computed tomography scanners in Kano metropolis complied with standard CT number for water and field uniformity but revealed high failure of noise tests.
