“…Furthermore, inherent dosimeters give outputs in dosimetric quantities specific to each modality. Some dosimetric quantities are: dose-area-product, 2 mGy.cm (fluoroscopy is), mean glandular dose, mGy (mammography), and volumetric computed tomography dose index, CTDI (mGy) and dosevol length product, DLP (mGy.cm) for computed tomography [2,9].…”

Background: Diagnostic reference levels (DRLs) help to identify unusually high dose levels in medical procedures involving radiation. This will subsequently, stimulate quality control. There are legislations and guidelines requiring the Member States of the European Union to adopt DRLs. While about 72% of European countries, as well as the United States, have complied, and with subsequent reviews demonstrating signiﬁcant dose reductions (16% – 30%), no evidence links any African country to replicate the same. Objective: This work brieﬂy reviewed the progress of Nigeria with regards to diagnostic reference levels (DRLs) and with particular attention to eﬀorts by radiographers. Methods: Google search was made with keywords of diagnostic reference levels as well as radiation dose in Nigeria. Over forty works were retrieved but only twenty- two which had speciﬁc relevance to the focus of the review were archived and read. The works were subsequently scrutinized to piece together the trend of DRLs globally, and locally. Results: Publications on x-ray, mammography, ﬂuoroscopy and computed tomography dose abound in Nigeria. Doses had wide variations in all modalities. There was no accessible evidence to indicate that any regulatory agency in Nigeria had keyed into the imperative of dose investigation, monitoring and reporting. Conclusion: In conclusion, diagnostic reference levels in x-ray, mammography and computed tomography have been recommended by independent researchers in Nigeria. Regulatory agencies are urged to summon the will to give guidelines on the implementation of these DRLs in order to improve the optimization of protection for patients.

Routine panoramic radiographs often reveal hidden lesions other than those related to the patient's chief complaint [1]. The study aims to determine the prevalence of incidental radiopacities in panoramic views. There are several conditions where calcifications can occur in soft tissue, including major and minor salivary glands, lymph nodes, and blood vessels, such as sialolith, phlebolith, exostosis, dystrophic calcifications, etc. [2]. Interpretation of panoramic radiograph should consider the possibilities of soft tissue calcification super-imposed in bone. Three hundred and sixty (360) panoramic radiographs are included in the study. The prevalence and distribution of radiopacities were documented along with the probable diagnosis. In addition, statistical analysis was done by SPSS software to evaluate the age and gender-related distribution of radiopacities in panoramic radiographs.
