Evaluation of neck masses by CT or MRI

Aim: To evaluate the role of CT or MRI in neck masses for pre-operative characterization based on location, extent, morphological characteristics and enhancement pattern. Materials & methods: The present study was conducted in the department of   Radiodiagnosis in co-ordination with the departments of E.N.T and Pathology at K.E.M. Hospital, Mumbai. A total of 50 (25 each of CT and MRI) patients with   palpable neck masses were included. Results: The study comprised of nodal and non-nodal masses. Out of 50 cases studied, 23 cases (46%) had benign lesions and 27 (54%) cases had malignant lesions. The overall male to female ratio was 0.85:1. MRI and CT made a correct diagnosis in 48 out of 50 cases, having a diagnostic accuracy of 96%. For evaluation of neck masses by CT or MRI, the sensitivity, specificity, positive predictive value and negative predictive value are 96.30%, 95.65%, 96.30% and 95.65% respectively. Conclusion: CT and MRI ensure accurate anatomical localization and lesion characterization in benign lesions. MRI has obvious advantages over CT in neck imaging like better soft tissue resolution, lack of ionizing radiation and safer contrast agents.
