Abstract
An apparatus for examining contrast agent movement in the body of a patient under the effect of gravity has an MR scanner with a patient support system which can be tilted around the longitudinal axis and/or transverse center axis for placing the patient in an oblique position within the magnet.
Claims8
A magnetic resonance examination apparatus comprising:
- a magnetic resonance scanner having an imaging volume;
- and
- a patient support system having a patient support shell adapted to receive a patient thereon containing contrast agent, said patient support element having a longitudinal axis and a transverse center axis, and said patient support system including a tilting apparatus connected to said patient support element for selectively tilting said patient support element around said longitudinal axis and said transverse center axis for orienting an entirety of a patient on said patient support element in an oblique position relative to either or both of said longitudinal axis and said transverse center axis, with at least a portion of said patient within said imaging volume, for producing contrast agent movement within said patient due to gravity.
A method for conducting a magnetic resonance examination of a subject, comprising the steps of:
- providing a magnetic resonance scanner having an imaging volume;
- injecting contrast agent into a patient;
- placing at least a portion of said patient, with said contrast agent therein, in said imaging volume on a patient support element having a longitudinal axis and a transverse center axis;
- and
- operating said magnetic resonance scanner with a True Fisp imaging sequence, while tilting said patient support element around either or both of said longitudinal axis and said transverse center axis for orienting an entirety of said patient on said patient support element obliquely relative to either or both of said longitudinal axis and said center transverse axis with at least a portion of said patient in said imaging volume to examine contrast agent movement in said patient due to gravity.
