Image rejection analysis of digital radiographic imaging system in Phrae Hospital

Abstract

This quasi-experimental research aimed to 1) analyze the reasons for the rejection rate of digital X-ray images due to can not be used for diagnosis and 2) compare the number of digital X-ray images rejected due to can not be used for diagnosis for diagnosis in both before and after the implementation of the radiology quality improvement guidelines. The sample group was digital radiographic images from ACROMA digital X-ray machine of X-ray room no. 1, Radiology Department, Phrae Hospital, of 72,837 images. Data were collected from ACROMA X-ray machine (X-ray room number 1) processing and using a digital X-ray image recorded form that categorized according to the cause of the organ found. Data were analyzed using descriptive statistics and a paired sample t-test.

The results of the research found that 1) the digital radiological images that were discarded because they could not be used for diagnosis before implementing the radiology quality development guidelines were 9.66 percent, the causes were positioning, QA/QC, and poor inspiration of 6.05%, 1.25%  and 0.99%, respectively. The analysis results by location or area of the X-ray images found that the majority were located in the Abdomen/KUB, Pelvis/hip, and Chest of 13.25%, 9.16%, and 11.89%, respectively. 2) The results of the comparison of the difference in the average value of the excluded X-ray images before and after implementing the radiology quality development guidelines found that after implementing the radiology quality development guidelines, the number of excluded X-ray images decreased less than before implementing the radiology quality development guidelines, with statistical significance level of 0.05 (t = 3.24, p-value = 0.04).
