Role Of Multi-slice Spiral Ct In Evaluation Of Neck Mass With Cytological Correlation

ABSTRACT

The swellings in the neck can be caused by innumerable pathological lesions arising from the various ana-tomical structures lying therein. Multi-Detector CT (MDCT) has now become the new standard in a radiological imag-ing modality. The utilization of MDCT has resulted in improved resolution and considerable reductions in scan acqui-sition and display time. Aim and Objective:This study is an effort to assess the role of MDCT in detection, charac-terization and diagnosing neck pathologies that correlate cytologically. Methods: A study of 50 cases in a clinically suspected neck mass was studied. Contrast-enhanced CT neck was done, and Specific CT criteria were used to charac-terize the mass so that a probable diagnosis could be made. MDCT diagnoses then compared with cytological results to conclude efficiency of MDCT analysis of neck mass. Results:In our study, the correlation between MDCT diagno-sis and pathological diagnosis was significant (p<0.001) when we compare both the modalities for diagnosing malig-nancy. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy is 92.3%, 87.5%, 88.9%,91.3%, 90% respectively. Conclusion:Multi-detector computed tomography helps in precise anatomical local-izationandcharacterizationofneckmasses.Hence,itwillbeamethodofchoiceforinitialevaluation,preoperativeplanning, and biopsy targeting and postoperative follow-up
