Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Aim: The aim of this study is to check the practical feasibility of artificial intelligence for day-to-day operations and how it generalizes when the data have considerable interobserver variability. Background: Automated delineation of organ at risk (OAR) using a deep learning model is reasonably accurate. This will considerably reduce the medical professional time in manually contouring the OAR and also reduce the interobserver variation among radiation oncologists. It allows for quick radiation planning which helps in adaptive radiotherapy planning. Materials and Methods: Head and neck (HN) computed tomography (CT) scan data of 113 patients were used in this study. CT scan was done as per the institute protocol. Each patient had about 100-300 slices in Dicom format. A total number of 19,240 images were used as the data set. The OARs were delineated by the radiation oncologist in the contouring system. Of the 113 patient records, 13 records were kept aside as test dataset and the remaining 100 records were used for training the UNet 2D model. The study was performed on the spinal cord and left and right parotids as OARs on HN CT images. The model performance was quantified using the Dice similarity coefficient (DSC) score. Results: The trained model is used to predict three OARs, spinal cord and left and right parotids. The DSC score of 84% and above could be achieved using the UNet 2D Convolutional Neural Network. Conclusion: This study showed that the accuracy of predicted organs was within acceptable DSC scores, even when the underlying dataset has significant interobserver variability.
