What the literature leaves open

  • Commission on Radiological Protection. Health Physics, 445-446. 95(4), https://doi.org/10.1097/01.hp.0000324200.73903.5b the of FULafia Journal of Science & Technology, Vol. 10, No.

    ESTIMATION OF EFFECTIVE DOSE FOR PATIENTS UNDERGOING COMPUTED TOMOGRAPHY SCANS FROM SELECTED DIAGNOSTIC CENTERS IN SOUTHWESTERN NIGERIA · 2026 · DOI

  • Recommendations are made based on the findings of the study. First, urgent protocol review at Hospital B is imperative, as the abdomen-pelvis doses were found to be 151 % higher than those at Hospital A (t = -21.3, p < 0.001), representing a systematic and unacceptable radiation protection deficit that demands immediate investigation through a comprehensive audit of technical parameters (mA, kV, scan length, and pitch) and dose modulation automated consideration implementation. Second, dose optimization for chest CT at both Hospitals is necessary, as both institutions exceed the British Columbia benchmark. Hospital B requires more urgent intervention, given its mean dose of 15.4 mSv; regular statistical comparisons using t-tests should be incorporated into routine quality assurance programs to monitor inter-hospital variation. Third, the Nigerian Nuclear Regulatory Authority (NNRA) and relevant professional bodies should prioritize developing National Diagnostic Reference Levels (DRLs) by using this study's pooled data to inform a preliminary national survey. Fourth, mandatory continuing education in radiation protection and dose optimization techniques should be instituted for all radiologists and radiographers who operate CT equipment. Finally, a larger, multicenter nationwide survey is urgently needed to establish robust national DRLs and monitor trends over time, as the highly significant negative t-value for abdomenpelvis (-21.3) provides compelling quantitative evidence that cannot be attributed to chance (p < 0.001) and underscores the critical need for systematic dose optimization programs across Nigeria.

  • Although there is no agreement on the actual risk involving low doses, the recommendations of ALARA, ALADA, and ALADAIP prevail, in line with the trend to uphold principles that balance the importance of X-ray diagnostic imaging with the intention of keeping the doses as low as possible.

  • Results: The local DRLs were established for thoracic CT exams, while, for abdominal-pelvic CT exams, the DRL curve was set as a substitute due to limited data.

  • CONCLUSIONS: The probability of induction of leukemia or other types of cancer is low, but the need for people to stay in the examination room during a CT examination should be limited to the necessary minimum.

  • Other cautions are that mobile phone studies to date have been able to address only relatively short lag periods, that almost no data are available on the consequences of childhood exposure, and that published data largely concentrate on a small number of outcomes, especially brain tumor and leukemia.
