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: To compare gross tumor volume (GTV) definition in locally advanced head and neck squamous cell carcinoma (LAHNSCC) using diffusion-weighted magnetic resonance imaging (DW-MRI) and computed tomography (CT) with intravenous contrast. Patients and Methods: Patients with LAHNSCC were imaged with CT and DW-MRI before treatment. GTV was delineated in both CT and DWMRI images by two investigators. CT and MRI images were co-registered and volume data were extracted for statistical analysis. Results: In general, DW-MRI volumes [based on the apparent diffusion coefficient (ADC)] were smaller than CT-based volumes. For all patients, GTV delineation based on pre-treatment DW-MRI was significantly smaller than that based on CT scan (CT-GTV) (p=0.0078). The mean difference (95% limits of agreement) between the two investigators was-0.37 cm3 for CT-GTV and 0.17 cm3 for ADC-GTV measurements, respectively. Conclusion: DWMRI radiotherapy GTVs are smaller than CT-based targets with less interobserver variability. Further validation of these preliminary results is necessary in a much larger patient group.
