BACKGROUND This study is an effort to assess the role of multidetector CT in evaluation of neck lesions. METHODS 50 patients with neck lesions were subjected to MDCT and images were analysed on plain scan and contrast enhanced scans done after I.V. administration of nonionic contrast. Lesions were studied on the basis of pattern of enhancement, vascular and bony involvement, and local invasion. Usefulness of CT examination regarding prediction of the benign and malignant nature of the lesions was analysed. RESULTS 27 malignant and 23 benign lesions were identified in our study. Accuracy of MDCT for predicting the benign and malignant nature of lesions was 97%. Final diagnosis of benign and malignant lesion was confirmed by histopathology examination. MDCT examination predicted the local invasion and vascular involvement of the lesion. CONCLUSIONS MDCT is very useful tool for localizing and characterizing neck lesions. Because of easy availability of vascular contrast enhancement, increased detection of the lesion, and multi-planar reformatting technology of MDCT, it can be considered as one of the good modalities for evaluation of neck lesions.
