Abstract
The aims of this study were to evaluate the ultrasound Quality Control (QC) testing in Najran, Saudi Arabia and to derive an accurate Gestational Age (GA) formula based on the errors of QC tests.
Using Gammex RMI and CIRS phantoms for twenty four ultrasound systems in the five hospitals the results of penetration depth, distance accuracy, image uniformity, dead zone and axial resolution were reported in this study. On the other hand, a dataset of 35 pregnancies were studied to assess the accuracy of GA during the first and second-trimesters.
Most QC results in all hospitals were found to be within the baseline levels and the best performance derived formula was found a combination of Biparietal Diameter (BPD), Femur Length (FL) and distance accuracy. Periodic QC evaluation should be carried out to motivate the optimization of accurate dating of pregnancy.
