SENSITIVITY OF ULTRASOUND COMPARED WITH MRI AND CT IN THE DETECTION OF EARLY NEOPLASMS

Abstract

Early detection of neoplasms significantly improves treatment outcomes and patient survival. Imaging modalities such as ultrasound (US), magnetic resonance imaging (MRI), and computed tomography (CT) play a crucial role in identifying early-stage tumors. Each technique differs in sensitivity, specificity, accessibility, and clinical applicability. Ultrasound is widely used as a first-line diagnostic tool due to its safety, cost-effectiveness, and real-time imaging capability, whereas MRI and CT provide higher soft-tissue contrast and spatial resolution in selected anatomical regions. This article analyzes and compares the sensitivity of ultrasound with MRI and CT in the detection of early neoplasms, highlighting their diagnostic advantages, limitations, and optimal clinical use. Special attention is given to the role of ultrasound in preclinical detection and its complementary relationship with advanced imaging modalities.
