Radiological procedures in Nigeria pose cancer risks. Pelvic exams showed higher cancer incidence and mortality probability, while chest exams indicated a significant increase in solid cancer mortality.
Area of Science:
- Radiological Protection
- Medical Imaging
- Public Health
Background:
- Diagnostic radiology procedures are widely used globally.
- Estimating radiation exposure and associated health risks is crucial for patient safety.
- Limited data exists on radiation exposure risks from common radiological procedures in Nigeria.
Purpose of the Study:
- To estimate the risk of radiation exposure to adult patients undergoing common radiological procedures.
- To assess the probability of cancer incidence and mortality from these exposures.
- To identify procedures with the highest associated risks in selected diagnostic centers in Lagos State, Nigeria.
Main Methods:
- Estimation of average effective doses for common radiological procedures.
- Calculation of cancer incidence and mortality probabilities based on effective doses.
- Analysis of data from selected diagnostic centers in Lagos State, Nigeria.
Main Results:
- Pelvis lateral (LAT) examination, despite a low effective dose, showed the highest probability of cancer incidence and mortality.
- Lumbar anteroposterior (AP) examination had the lowest associated cancer risk.
- Chest posteroanterior (PA) examination indicated a high percentage increase in solid cancer mortality (53.7%).
Conclusions:
- Certain common radiological procedures, particularly pelvic examinations, may carry a higher risk of cancer incidence and mortality.
- Chest PA examinations are associated with a significant increase in cancer mortality.
- Findings highlight the need for optimized radiation protection measures in diagnostic radiology centers in Nigeria.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
