Abstract :

Aims & Objectives of Study: To study the role of USG & CT in evaluation of major salivary glands lesions with HPE correlation wherever possible. Materials and methods: 54 patients with salivary gland lesions were subjected to USG (TOSHIBA APLIO–500; 7.5 to 10 MHz linear transducer) & CT scan (SIEMENS SOMATOM SPIRIT SCANNER. CT scan) and imaging findings were recorded. The findings were correlated with HPE. Results: Of the 54 salivary gland lesions, 26 (48.1 %) were non–neoplastic, 22 (40.7 %) were benign and 6 (11.2 %) were malignant. Sensitivity and Specificity of USG in differentiating Benign and Malignant Tumors were found to be 90.4 %, 80.0 % respectively whereas for CT it was 93.3 % and 80.0 % respectively. Conclusion: For superficial salivary gland lesions, USG is better. CT should be used to see the deep extension of lesion and for assessment of bony destruction if any.
