Abstract

Objectives: To assess the reliability of Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) and ultrasound (US) in evaluating thyroid and salivary glands lesions.

Background: The thyroid and salivary glands are regions of considerable anatomical and functional complexity with a challenging diagnosis. CT or MRI or US is performed for pretherapeutic assessment of their Lesions. All can supply the information needed by the clinician for adequate treatment planning.

Patients and Methods: 21 patients with thyroid lesions and 13 patients with salivary glands lesions were evaluated by CT and/or MRI and/or US according to the decision of the treating physician. The results of imaging were assessed based on the corresponding histopathological diagnosis to define the true benign, true malignant, false benign and false malignant results. Statistical analysis was done to calculate the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of each technique.

Results: The study included 34 patients distributed among 2 anatomical lesions thyroid (21), salivary glands (13). The lesions included 18 malignant, 10 benign neoplastic and 6 inflammatory lesions. U.S was performed for all patients while C.T was performed for 27 patients while MRI was performed for 20 patients. US for thyroid revealed a sensitivity of 91.7%, a specificity of 77.8%, a diagnostic accuracy of 85.7%. CT for thyroid revealed a sensitivity of 70%, a specificity of 66.7%, a diagnostic accuracy of 68.8%. MRI for thyroid revealed a sensitivity of 75%, a specificity of 75% and a diagnostic accuracy of 75%. US for salivary glands revealed a sensitivity of 83.3%%, a specificity of 85.7%, a diagnostic accuracy of 84.6%. CT for salivary glands revealed a sensitivity of 80.9%, a specificity of 83.3%, a diagnostic accuracy of 81.7%. MRI for salivary glands revealed a sensitivity of 100%, a specificity of 75% and a diagnostic accuracy of 87.5%.

Conclusion: Ultrasound, computed tomography and magnetic resonance imaging, all are effective imaging modalities for evaluating a gland mass. Every anatomical region in the neck has its own criteria making it the target of a specific imaging modality. So ultrasound is the preferred imaging technique for thyroid and salivary glands followed by MRI then C.T.
