Objective:To evaluate the image quality of sesamoid axon X-ray projection in sitting posture.Methods:A total of 50 patients who came to the clinic due to foot discomfort from March 2023 to June 2023 were collected,and DR ex-amination of the sesamoid axial position in prone and sitting postures was performed on the same patient,and the quality of the two sets of images was evaluated and compared.Results:There were no statistical differences in image qualification rate,EI and DAP in prone and sitting postures.Conclusion:When taking sesamoid axial-view X-ray,patients who cannot perform traditional posture(prone position)projection can be taken in a sitting position,and the X-ray images obtained can also meet the diagnostic needs of radiologists.
