“…The left and right arrows indicate the 10th and 75th percentile dose distribution. The determined DRLs (75th percentile) and the use of their values serve as a quality improvement tool, (27) but do not indicate the best practice. The DRLs obtained in this study were compared with the mean value calculated from each hospital investigated and were reported to the management of each health‐care center that participated in the study.…”

“…It is expected that mean doses for three‐quarters of the hospitals are below the DRLs and one‐quarter are above (24) . The left arrow shows the 10th percentile of the dose distribution, and any radiation doses that are substantially lower than these values may be associated with poor image quality that could result in inadequate diagnostic information (27) . Radiation doses, such as represented by 10th percentile, may require investigation into adequacy of image quality.…”

“…It is extremely difficult to collect a sizeable data of standard size patient in Nigeria. To overcome this, DAP normalization factor of NRPB 24 , 27 was applied to the doses of all the patients measured. The normalization factor transforms the dose of any patient to the dose of a “reference man” (27) .…”

In Nigeria, a large number of radiographic examinations are conducted yearly for various diagnostic purposes. However, most examinations carried out do not have records of doses received by the patients, and the employed exposure parameters used are not documented; therefore, adequate radiation dose management is hindered. The aim of the present study was to estimate the dose‐area product (DAP) of patients examined in Nigeria, and to propose regional reference dose levels for nine common examinations (chest PA, abdomen AP, pelvis AP, lumbar AP, skull AP, leg AP, knee AP, hand AP, and thigh AP) undertaken in Nigeria. Measurement of entrance surface dose (ESD) was carried out using thermoluminescent dosimeter (TLD). Measured ESDS were converted into DAP using the beam area of patients in 12 purposely selected hospitals. Results of the study show that the maximum/minimum ratio ranged from 3 for thigh AP to 57 in abdomen AP. The range of determined mean and 75th percentile DAPs were 0.18–17.16, and 0.25–28.59 Gy cm2, respectively. Data available for comparison show that 75th percentile DAPs in this study (in chest PA, abdomen AP, pelvis AP, lumbar AP) are higher than NRPB‐HPE reference values. The DAP in this study is higher by factor of 31.4 (chest PA), 9.9 (abdomen AP), 2.2 (pelvis AP), and 2.1 (lumbar AP) than NRPB‐HPE values. The relative higher dose found in this study shows nonoptimization of practice in Nigeria. It is expected that regular dose auditing and dose optimization implementation in Nigeria would lead to lower DAP value, especially in abdomen AP. The 75th percentile DAP distribution reported in this study could be taken as regional diagnostic reference level in the Southwestern Nigeria; however, a more extensive nationwide dose survey is required to establish national reference dose.PACS number(s): 87.53.Bn, 87.59.B

The purpose of this study is to measure and evaluate radiation dose on patients in interventional radiological(IVR) procedures classified by each procedure, and aid as data for safety management. Fluroscopy time(F-time), dose area product(DAP) and number of acquired images from each kind of procedure was checked. Non-vascular procedures showed low value, and vascular procedure showed high value in all procedures except in IVC filter. F-time was longest in EVAR, which showed also the highest DAP value of all procedures. DAP-rate showed high value in TACE. By this result, we attempt to establish standard guideline of radiation dose on patients in IVR procedure.

Purpose To provide current data on average air kerma‐area product (PKA) and effective dose (E) for noncardiac interventional fluoroscopy procedures and suggested values of dose coefficients (DCE) for conversion of PKA to estimates of effective dose. Methods A PubMed literature search covering the time period from 2006 to August 2019 was performed to obtain recent data on PKA, E and DCE for interventional fluoroscopy procedures. Results There is very wide variation in the reported values of PKA, E, and DCE in the literature. A number of factors are involved in this variability and the resultant uncertainty in average values of these dose quantities. Conclusions The values of PKA, average E and suggested DCE presented here can be of use for comparison of the radiation detriment from different procedures and may be useful for categorizing detriment within an order of magnitude or so. They do not represent actual or expected radiation dose or detriment from any specific procedure or for a specific patient and should be not be used as such.
