7 Tesla MRI Scanner Sheds New Light on the Hypothalamus

Model BrainA new study published in PLOS One looks at the Hypothalamus using a sequencing technique on the images produced by a 7 Tesla MRI scanner. MRI competes with other methods for understanding anatomy. Post-mortem histological studies make estimates of volume based on shrinkage of brain structures after death. In addition, histological studies look at the properties of brain matter highlighted by the staining technique.

With MRI, the researchers are able to image the Hypothalamus using several properties of the tissue. The researchers in this study contrasted the volume of the Hypothalamus estimated using this approach with that of other methods. The researchers estimated the volume of the bilateral Hypothalamus at 1.1 cm3. In their discussion the researchers emphasise the importance of other approaches including histology in utilising the study results for a better understanding of anatomy.
