Role CT imaging for Cancer Diagnosis by Determining Sensitivity and Specificity: 144 Cancer Cases in Tobruk, Libya

Computed tomography (CT) has emerged as a highly accurate and the most effective technique for detecting and diagnosing various types of cancer. It also aids in evaluating the cancer's stage, size, and form. CT has become the mainstay for cancer detection in Libya, where cost and accessibility are the primary factors determining the modality for diagnostic purposes. The study aims to evaluate the role of CT by correlating the CT scan results with histological findings and determining its sensitivity and specificity in diagnosing various cancers. The study was conducted on 144 patients who underwent CT scans between January 2023 and March 2024. The age range of 31–40 years had the highest percentage of cases, with 39 (27.08%). A CT scan showed 98.52% sensitivity and 87.50% specificity, demonstrating high accuracy in identifying malignant and benign cases. The precision and accuracy of CT scans were 99.25% and 97.91%, respectively. This study demonstrates that CT is highly sensitive in detecting cancers, making diagnoses, and particularly in identifying its morphology and type, estimating whether it is benign or malignant, and identifying any other associated findings with high sensitivity and specificity.
