The recent Food and Drug Administration approval of 7 T MR imaging scanners for clinical use has introduced the possibility to study the brain not only in physiologic but also in pathologic conditions at ultrahigh field (UHF). Because UHF MR imaging offers higher signal-to-noise ratio and spatial resolution compared with lower field clinical scanners, the benefits of UHF MR imaging are particularly evident for imaging small anatomic structures, such as the cerebral perivascular spaces (PVS). In this article, the authors describe the application of UHF MR imaging for the investigation of PVS.

UI MeSH Term Description Entries
D008279 Magnetic Resonance Imaging Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D001927 Brain Diseases Pathologic conditions affecting the BRAIN, which is composed of the intracranial components of the CENTRAL NERVOUS SYSTEM. This includes (but is not limited to) the CEREBRAL CORTEX; intracranial white matter; BASAL GANGLIA; THALAMUS; HYPOTHALAMUS; BRAIN STEM; and CEREBELLUM.

D000077502 Glymphatic System A vascular waste clearance system in the brain analogous to the lymphatic system that facilitates transporting of solutes and waste products from CEREBROSPINAL FLUID (CSF) and brain INTERSTITIAL FLUID (ISF). CSF from the SUBARACHNOID SPACE enters the brain periarterial spaces, into the interstitium via channels (e.g., AQUAPORIN 4 PROTEIN) on astrocytic endfeet and exchanges with brain ISF before perivenous drainage of solutes and waste.
