Abstract
In a method for analyzing cerebrospinal fluid perfusion by magnetic resonance imaging, a contrast agent is directing injected into volumes containing cerebrospinal fluid and a magnetic resonance image of those volumes is obtained. After a suitable waiting time, at least one further magnetic resonance image of the volumes is obtained. The (at least) two magnetic resonance images of the volumes are then compared and the degree of perfusion of the contrast agent is identified as an indicator of the perfusion and/or flow of cerebrospinal fluid in the volumes.
Claims5
A method for analyzing cerebrospinal fluid perfusion in a living subject comprising the steps of:
- injecting a contrast agent directly into volumes, in a volume of interest, filled with cerebrospinal fluid via a minimally invasive access route to said volumes;
- obtaining a first magnetic resonance image of said volume of interest in a first magnetic resonance examination;
- waiting for a waiting time after obtaining said first magnetic resonance image;
- obtaining a second magnetic resonance image of said volume of interest in a second magnetic resonance examination after said waiting time;
- and
- comparing said first magnetic resonance image and said second magnetic resonance image and evaluating a degree of perfusion of said contrast agent in said volumes in said volume of interest as an indicator or at least one of perfusion and flow of said cerebrospinal fluid in said volumes.
