Does MRI Solve Liver Problems?

MR imaging is considered the most accurate modality to the image the liver for the detection and characterization of focal and diffuse liver diseases.The superiority of MR imaging compared with other imaging modalities for liver evaluation has become more even apparent because of substantial improvements in 1.5 T magnets with faster image acquisition and better quality. Advancements in MR imaging hardware ,software and contrast agents have made a major impact on imaging of the liver, phased array surface coil technology significantly improved SNR and conventional spin echo pulse sequences have been replaced by faster sequences .Gradients-echo (GRE) sequences generally are used for T1–weighted sequences and echo-train sequences are used for T2–weighted sequences. Introduction of parallel imaging techniques has enabled further reduction of acquisition time and improved spatial resolution.
