1. IMAGING OF MASS LESIONS OF TONGUE ABSTRACT NO : 1171

2. AIMS & OBJECTIVES To demonstrate the role of Multi detector computed tomography and Magnetic Resonance Imaging in detection of mass lesions of tongue. To demonstrate their role in pre operative diagnosis and management.

3. MATERIALS & METHODS 29 patients with mass lesions in tongue are evaluated with CT or MRI for a period of 7 months from March 2014 till October 2014. CT - 64 Slice GE Contrast enhanced Axial, Coronal and Sagittal images MRI - 1.5 Tesla GE 16 channel MRI. Three plane T1, T2 FS are basic sequences.

7. DEMOGRAPHIC DISTRIBUTION

8. SQUAMOUS CELL CARCINOMA Squamous cancers of gingivobuccalregion,oral tongue and retromolar trigone are common oral cancers in our country. Among these carcinoma tongue is the second most common. Lateral border- most common site. Staging is important in the management.

28. CONCLUSION Though MR is the sensitive imaging modality for tongue evaluation, CT is most commonly used in preoperative assessment and post operative surveillance. When CT and MRI are combined together the sensitivity and specificity of delineating tongue lesions is increased.

29. TAKE HOME MESSAGE CT -cortical erosions. MRI -soft tissue extension, bone marrow involvement and peri neural spread. CT and MRI are complementary in evaluating tongue lesions.
