MR Imaging in Differential Diagnostics of Liver Lesions
- II. rádiologická klinika LF UK a OÚSA, Bratislava
Diagnosis of focal liver lesions is „the daily bread“ of each radiologist and means a diagnostic problem. Although ultrasound (US) and computer-assisted tomography (CT) are routinely used in imaging algorithm, magnetic resonance imaging (MRI) is still the golden standard, especially in those cases, when former imaging cannot give an unambiguous determination of the biological characteristic of the lesion. MRI should be performed before any invasive procedure (biopsy).
Main advantages of MRI are better tissue resolution, multiplanar imaging feasibility (nowadays also possible with the newest CT equipment), absence of radiation, minimal risk of allergic reaction after contrast administration and especially the use of hepatotropic contrast media. On the other hand, the disadvantage of MRI is a limited examination in patients with metallic implants and absolute contraindication in patients with electronic implants.
