MRI can accurately quantify liver iron concentration (LIC) by using T2* sequences. Vendor based, commercially available 3D multi-echo Dixon sequences provide maps of liver T2*/R2* and allow automated, inline post-processing, avoiding conventional manual post-processing. The purpose of our study was to compare R2*/LIC estimates generated by automated 3D multi-echo Dixon sequence to values generated by GRE-based R2* relaxometry as the reference standard. Read More

El hígado es el principal sitio de almacenamiento de hierro en humanos, y la concentración de hierro en el hígado se correlaciona estrechamente con las reservas de hierro en todo el cuerpo. La técnica de resonancia magnética (MR) es capaz de separar las señales de agua y grasa para cuantificar la infiltración de hierro y grasa en el hígado. Esto permite obtener una mejor cuantificación del hierro y observar la relación que existe con el índice de masa corporal (IMC). En este trabajo se propone una medición de acuerdo a lo propuesto por la divisón anatomica por Couinaud. Read More

Neurodegeneration with Brain Iron Accumulation comprises a clinically and genetically heterogeneous group of disorders that share the feature of high levels of iron in the basal ganglia. Although very rare, these disorders may be suspected commonly by radiologists when iron deposits in the basal ganglia are encountered. Generally, radiologists are not familiar with the MR phenotypes of these disorders beyond the typical ‘eye of the tiger’, which may lead to overcalling since nonspecific iron deposits in the basal ganglia are way more common than NBIA. The aim of this educational poster is to discuss the MR phenotypes of the four most common NBIA disorders to include BPAN, PKAN, PLAN and MPAN, comprising about 95% of the cases. We will not only review the typical auntminnie presentation but also, we will describe the earliest signs, such as the T2 hyperintense streak along the medial border of the pallidi of PKAN, interestingly before any iron deposition is evident. When available, we will discuss the follow-up cases to see how the patterns evolve over time. Finally, we will briefly review the anatomy of the basal ganglia, subthalamic nuclei, substantia nigra and their connections since it is of the utmost importance for the pattern recognition. We hope that this review helps radiologists recognize the NBIA phenotypes to be more confident in their differentials. Read More
