THE ROLE OF CT IN THE EARLY DETECTION AND CHARACTERIZATION OF DIFFERENT TYPES OF CANCERS

The early detection and accurate characterization of cancers are critical to improving patient prognosis and treatment outcomes.This thesis explores the role of computed tomography (CT) in the early identification and characterization of various cancer types, including lung, colorectal, breast, and liver cancers.Using both retrospective and prospective analyses, this study examines how CT imaging techniques, including multiphase contrast-enhanced scans and high-resolution imaging, contribute to the early diagnosis of tumors at various stages.The research highlights the ability of CT to detect tumors that are not visible through traditional clinical examination or other imaging methods, especially in the early stages of cancer development.Additionally, the study evaluates the effectiveness of CT in determining the size, location, and characteristics of
