A Study of CT-GUIDED Fine Needle Aspiration Cytology of Thoracic Lesions

Abstract

Background: The study of CT-guided fine needle aspiration cytology (FNAC) of thoracic lesions is an essential diagnostic technique used to evaluate and distinguish between benign and malignant lesions in the thoracic cavity. This minimally invasive procedure enables precise targeting of lesions that are difficult to access through conventional methods.

Aim: To assess the diagnostic accuracy, sensitivity, and specificity of CT-guided FNAC for thoracic lesions.

Methods: A cross-sectional study was conducted on 100 patients suspected of having thoracic lesions. Each patient underwent CT-guided FNAC, and the results were compared with histopathological outcomes. Sensitivity, specificity, and diagnostic accuracy were calculated.

Results: The study showed that CT-guided FNAC has an overall diagnostic accuracy of 89%, with a sensitivity of 86% and specificity of 92%. Malignant lesions, such as lung carcinoma, accounted for 55% of diagnoses. The most common benign conditions were granulomatous infections (25%).

Conclusion: CT-guided FNAC is an effective, safe, and minimally invasive diagnostic tool for evaluating thoracic lesions. It provides accurate and reliable results with a low rate of complications.
