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

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.
