Background: The use of x-rays in radiation imaging is ever increasing in magnitude
with increase in radiological procedures, and complexity of radiology equipment,
Computed Tomography (CT) scanning included. Quality management with patient
radiation dose monitoring is fundamental in optimising radiation protection and safety
while optimising image quality.
Objective: To assess the level of quality management with respect to quality assurance,
image quality and patient dose in CT facilities in Kenya.
Methodology: A quantitative method was developed and used to score the results
obtained from the physical image quality, patient dose and quality assurance
inspection results. Physical images were obtained from American Association of
Physicists in Medicine (AAPM) water phantom, and patient dose measured using
head and body phantoms. The results obtained were compared with internationally
recognized standards including the European Guidelines Quality Criteria for CT and
the International Basic Safety Standards for Protection against Ionizing Radiation.
Study Design: A quality assurance inspection, physical image quality and patient
dose assessment in eighteen representative CT facilities.
Results: The overall findings placed the national quality management performance
level at 57 ± 2% while patient dose, image quality and quality assurance administration
performance were 71 ± 4%, 61 ± 3% and 40 ± 2%, respectively.
Conclusion: The national level in quality management system in diagnostic radiology
was benchmarked as good. Diagnostic Reference Levels (DRLs) were proposed in
order to enhance the optimization of radiological protection of patients in Kenya. In
future, we hope to demonstrate optimization of patient dose using typical patient dose
in the new state-of-the-art multi-slice CT.
Recommendation: Kenya should adopt Radiology facility accreditation system
whereby a scrutiny of scores from each stage in the medical imaging chain is performed
to enhance quality improvement.
