The clinical diagnosis, treatment, and prognosis of gastric cancer heavily rely on imaging examinations. The conventional imaging reports often suffer from descriptive and non-structured issues, which may lead to omission of critical information or inconsistent interpretations, thereby compromising clinical decision-making. Therefore, the standardized radiological assessment for gastric cancer is of paramount importance. The West China Hospital of Sichuan University has involved in developing and implementing a CT imaging structured reporting for gastric cancer. This structured reporting, based on authoritative guidelines, integrates key diagnostic elements to ensure comprehensive information and standardized reporting, while also serving quality control and educational purposes. Now we introduce the design, application, and features of the structured reporting at West China Hospital of Sichuan University, aiming to promote standardized documentation of gastric cancer CT imaging reports.

This paper explores the relationship between the cardiac volume and time, which is applied to control dynamic heart phantom. We selected 50 patients to collect their cardiac computed tomography angiography (CTA) images, which have 20 points in time series CTA images using retrospective electrocardiograph gating, and measure the volume of four chamber in 20-time points with cardiac function analysis software. Then we grouped patients by gender, age, weight, height, heartbeat, and utilize repeated measurement design to conduct statistical analyses. We proposed structured sparse learning to estimate the mathematic expression of cardiac volume variation. The research indicates that all patients’ groups are statistically significant in time factor (P = 0.000); there are interactive effects between time and gender groups in left ventricle (F = 8.597, P = 0.006) while no interactive effects in other chambers with the remaining groups; and the different weight groups’ volume is statistically significant in right ventricle (F = 9.004, P = 0.005) while no statistical significance in other chambers with remaining groups. The accuracy of cardiac volume and time relationship utilizing structured sparse learning is close to the least square method, but the former’s expression is more concise and more robust. The number of nonzero basic function of the structured sparse model is just 2.2 percent of that of least square model. Hence, the work provides more the accurate and concise expression of the cardiac for cardiac motion simulation.
The patients with rectal cancer account for 50% or more of patients with colorectal cancer. The rectal magnetic resonance imaging (MRI) plays a pivotal role in clinical practice for evaluating the treatment baseline of tumors. The structured report of MRI serves as the foundation so as to promote homogenized, standardized, and normalized diagnosis and treatment of rectal cancer. We presented the MRI-based baseline evaluation structured reporting system for rectal cancer developed by West China Hospital of Sichuan University, aiming to advance the standardization and normalization of imaging reports for treatment baseline assessment in rectal cancer.
Liver cancer is a highly prevalent malignancy of the digestive system in China. Hepatic imaging examinations, including CT and MRI, play a critical role in the screening, diagnosis, and therapeutic evaluation of liver cancer. To standardize terminology, reduce variability in imaging interpretation, and improve diagnostic consistency and accuracy, the Department of Radiology of West China Hospital of Sichuan University has developed a CT/MRI structured reporting specifically designed for high-risk populations of primary liver cancer, which is based on the 2018 version of the Liver Imaging Reporting and Data System published by the American College of Radiology. We introduce the design background, core elements, and practical application experience of the CT/MRI structured reporting developed by West China Hospital of Sichuan University, aiming to promote the standardization and uniformity of hepatic imaging evaluation for high-risk populations of liver cancer.
ObjectiveTo analyze the value of structured electronic medical records for pulmonary nodules in increasing the ability of outpatient service and hospital management by resident physicians.MethodsWe included 40 trainees [94 males and 26 females aged 22-31 (26.45±2.81) years] who were trained in the standardized training base for surgical residents in our hospital from January 2018 to January 2021. The trainees were randomly divided into two groups including a structured group using the structured electronic medical record for pulmonary nodule and an unstructured group using unstructured electronic medical record designed by our department. The time of completing hospitalization records and first-time course records, the quality of course records, the accuracy of issuing admission orders, the quality of teaching rounds, and patient’s satisfaction between the two groups were analyzed and compared.Results(1) The average time in the structured group to complete inpatient medical records was significantly shorter than that of the unstructured group (53.61±8.12 min vs. 84.25±16.09 min, P<0.010); the average time in the structured group to complete the first-time course record was shorter than that of the unstructured group (13.20±5.43 min vs. 27.51±8.62 min, P<0.010), and there was a significant statistical difference between the two groups. (2) The overall teaching round quality score of the students in the structured group was significantly higher than that in the unstructured group (84.21±15.61 vs. 70.91±12.28, P<0.010). (3) The score of the medical record writing quality of the structured group was significantly higher than that of the unstructured group (80.25±9.22 vs. 74.22±5.40, P<0.010).ConclusionThe structured electronic medical record specific for pulmonary nodules can effectively improve the training efficiency in the standardized training of surgical residents, improve the clinical ability to deal with pulmonary nodules, improve the integrity and accuracy of key clinical data collected by students, and improve doctor-patient relationship.
