dc.description.abstract | La resonancia de hígado ha ganado un papel importante en el diagnóstico y caracterización de las lesiones hepáticas dados los avances tecnológicos que han disminuido el tiempo de adquisición de las imágenes, a más de la utilización de nuevas secuencias y de gadolinio, los que aporta datos sobre la vascularización. Los quistes y los hamartomas de la vía biliar son hipointensos en T1 e hiperintensos en T2; se diferencian porque los últimos presentan un anillo delgado de captación de gadolinio. Los hemangiomas, más comunes en mujeres, son hipointensos en T1 y moderadamente hiperintensos en T2, con un realce centrípeto en la fase arterial. La hiperplasia nodular focales es iso a levemente hipointensa en T1 e iso a levemente hiperintensa en T2, capta intensamente el medio en la fase arterial, tienen una cicatriz central que en las fases tardías llega a ser isointensa a levemente hiperintensa. Los adenomas son moderadamente hipointensos en T1 e isointensos a levemente hiperintensos en T2, tienen realce marcado en la fase arterial pero desaparece en la fase venosa y tardía, persistiendo un anillo de realce. Los nódulos de regeneración son isointensos en T1 e iso a hipointensos en T2, los nódulos displásicos son hiperintensos en T1 e iso a hipointensos en T2, diferenciándose del carcinoma hepatocelular porque generalmente son menores de 2 cm y el carcinoma presenta realce marcado y heterogéneo del contraste en la fase arterial.

dc.description.abstractenglish | MR imaging of the liver has gained an important role in the diagnosis and characterization of the hepatic lesions due to the technological advances that have diminished the acquisition time of the images, the use of new sequences and contrast media to show the paterns of vascularización. Cysts and bile duct hamartomas are hypointense in T1 and hyperintense in T2; they are differentiated by a thin ring of gadolinium enhancement, hemangiomas are more common in women, they are hypointense in T1 and moderately hyperintense in T2, with a centripetal enhancement in the arterial phase. Focal nodular hiperplasia is iso to slightly hypointense in T1 and iso to slightly hyperintense in T2 and enhances intensely in the arterial phase, and has a central scar that in the delayed images gets to be isointense to slightly hyperintense. Adenomas are moderately hypointense in T1 and isointense to slightly hyperintense in T2, they have marked enhancement in the arterial phase but it disappears in the venous and delayed images, persisting an enhancing ring. Regenerative nodules are isointense in T1 and iso to hypointense in T2, displástic nodules are hyperintense or hypointense in T1 and iso in T2, they differ from hepatocelular carcinoma because they are generally less than 2 cm and because carcinoma has noticeable and heterogenous enhancement in the arterial phase.
