| titleOfInvention | Quantitative T1 determination in MR imaging |
| abstract | A method for quantitative T1 determination in MR imaging of a volume portion of an examination subject (O) dependent on contrast agent delivery, the method comprising: Acquiring MR data of the volume segment when administering a contrast agent to the examination subject (O), wherein the MR data of the volume section are detected several times at different phases of a propagation of the contrast agent in the volume section, wherein first MR data of the volume portion is acquired with a first sequence and second MR data of the volume portion is acquired with a second sequence, wherein the first sequence is defined by the tilt angle (α 1 , α 2 ) of at least one RF included in the sequence Pulse and / or by the repetition time (TR) from the second sequence, and Determining T1 values per voxel of the volume section as a function of the first MR data and the second MR data, wherein, based on the first MR data and the second MR data, which are acquired at the same phase, in addition to the T1 value the proton density per voxel is determined, and where the proton density per voxel is assumed to be constant, such that for one of the phases for which the MR data is acquired only with a sequence having only one tilt angle and only one repetition time (TR), the T1 value per voxel is determined on the basis of the assumed proton density per voxel. |
