Влияние нарушений качества рентгенографических исследований органов грудной клетки на работу врачей-рентгенологов и диагностического искусственного интеллекта.

Abstract

When performing radiographic studies, quality violations and errors periodically occur, making it difficult for an image to be interpreted and described by both a radiologist and software based on artificial intelligence technology. Incorrect filling of meta-information in DICOM format headers may be a separate problem for diagnostic artificial intelligence. Purpose: determination of quality violations of the chest x-ray examinations, which most strongly impede the work of radiologists and diagnostic software based on artificial intelligence in the conditions of the Moscow city health care system. Material and methods. To study the impact of the quality of x-ray examinations on the work of a radiologist, an online survey was conducted among radiologists, employees of the Moscow reference center for radiation diagnostics. To study the impact of the quality of x-ray examinations on the work of AI-based software, an analysis of the results of processing diagnostic studies according to the modalities chest x-ray and lung fluorography for the 4th quarter of 2023 by artificial intelligence services was carried out as part of an “Experiment on the use of innovative computer vision technologies for medical image analysis and subsequent applicability in the healthcare system of Moscow”. Results. The survey involved 172 radiologists. The most common quality violations by doctors are incompleteness of chest coverage and asymmetric position of the patient, as well as violations of image clarity / contrast. At the same time, the incompleteness of the chest coverage causes the greatest difficulties in interpreting the study for doctors with up to 5 years of experience. For more experienced doctors, the greatest difficulties are caused by violations of the clarity and contrast of images. The main problems hindering the description of studies by AI-services are non-filling or incorrect filling of meta-information about the study stored in DICOM format, as well as violations of the patient’s laying and positioning. Conclusion. The problems we have identified indicate the need for more careful adherence to the methodology of conducting diagnostic studies, especially with regard to filling out meta-information about the study. AI-based software developers need to evaluate the performance of their solutions based on the developed testing and monitoring methodology.
