Abstract: Background: Accurate preoperative local staging of rectal cancer is essential for individualized treatment planning; however, the optimal imaging modality and personalized assessment approach remain controversial. This study aimed to compare the performance of different imaging modalities in the evaluation of local staging for rectal cancer and to identify factors related to their inaccurate predictions. Methods: ), tumor location (on longitudinal and transverse sections), and neoadjuvant chemoradiotherapy (NCRT) history (with or without). Results: 89.66% for location) (P<0.05). Compared with the non-anterior group, the predictive accuracy of MRI decreased in the anterior group, whereas 3D-ERUS showed the opposite trend, with no statistical significance. The accuracy of 3D-ERUS was unaffected by the patient's BMI and tumor location (P>0.05). Conclusions: ) and rectal tumors located at a low position (≤5 cm from the anal margin), 3D-ERUS may have a better performance for local staging assessment of rectal cancers. Thus, it can be an important complement to conventional imaging modality on specific occasions.
