Exploratory
Not applicable
The diagnostic sensitivity of LLN metastasis on MRI
1. The specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of the diagnosis of LLN metastasis on MRI.
2. The coincidence ratio of morphologic change assessments among the observers
3. The correlation between extramural venous invasion (EMVI) of the primary lesion and LLN metastasis
4. The influence of neoadjuvant therapy for the diagnosis of LLN metastasis on MRI
5. The correlation between the LLN metastasis diagnosed by MRI and the patients' prognosis
6. The difference between the diagnostic accuracy of LLN metastasis on MRI and CT

Male and Female
1) A case with primary rectal cancer is scheduled for TME and LLND
2) A case with histologically confirmed adenocarcinoma
3) Informed consent is obtained for participation in the study
4) Regarding Step 1, the postoperative registration is permissible.
1) A case with a contraindication for MRI, such as use of artificial devices (e.g., cardiac pacemaker)
2) A case wherein assessing the status of LLN metastasis on MRI imaging is difficult because of intrapelvic artifacts
3) A case with an intrapelvic neoplasm, barring colorectal cancer, such as prostate cancer, bladder cancer, uterine cancer, and ovarian cancer.
4) A patient who is deemed to be inappropriate for study enrolment by the principal investigator or researcher
