Objective To explore the CT and MRI findings of tongue cancer. Method 2 In 1 case of tongue cancer, 7 cases underwent CT scan and 14 cases underwent MR scan. Results Of the 7 cases, 5 showed tumor in CT scan and 14 showed MRI in all 14 cases. CT and MRI showed direct invasion around the tumor. 2 cases showed destruction of mandible and no damage to MRI. Both MRI scan and CT scan Can show carotid interstitial lymph node metastasis. Conclusion MRI is superior to CT in displaying tongue cancer and metastasis of soft tissue lesions. CT is the best method to find cortical bone invasion
