Análise comparativa da tomografia computadorizada e ressonância magnética em tumores hepáticos benignos

Abstract

The liver, a vital organ of the digestive system, is susceptible to injury and disease due to factors such as excessive alcohol consumption and poor lifestyles. Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) are essential imaging techniques for the diagnosis of liver tumors, allowing the identification of benign lesions, such as adenomas, focal nodular hyperplasia and hemangiomas. Hepatic adenoma, often found in young women, is asymptomatic and diagnosed incidentally. Focal nodular hyperplasia is characterized by a hypervascular mass and generally does not require treatment. Hepatic hemangioma is the most common benign tumor and is most often asymptomatic. Both imaging methods have specificities: computed tomography is quick, but involves exposure to radiation and uses iodinated contrast, while magnetic resonance imaging, considered the "gold standard", does not use radiation and offers more detailed visualization of the lesions, with better sensitivity and specificity. The comparison between computed tomography and magnetic resonance highlights the superiority of magnetic resonance in the characterization and diagnosis of liver tumors, emphasizing the importance of continuous training of health professionals and updating research in the area.
