US, CT and MRI in comparison

The diagnostic clarification of the liver is a frequent problem in clinical routine. Different imaging techniques including ultrasound (US), computer tomography (CT), and magnetic resonance imaging (MRI) are used to detect and classify liver lesions But all modalities provide benefits and limitations. To ensure the best treatment for the patient, preferably all lesions should be detected. Therefore, choosing the modality with the most benefits and least limitations is essential.

When comparing CT and MRI with ultrasound, the ultrasound of the liver is the least expensive examination. Due to the high availability of ultrasound systems and the relative simplicity of performing the examination, the clinical relevance of the examination is high. The diagnostic accuracy of ultrasound for the detection and characterization of focal liver lesions is estimated to be lower than that of CT and MRI.

In comparison to MRI, CT examination of the liver is less expensive in most countries since it is widely available, but MRI is estimated to be more accurate both for the detection and characterization of liver lesions.
