What is an Assay?Filters
Complete original MRI data for POD3. Bruker format but human readable link names as exam folder, so instead of 2/ the folder is named E002_Anatomy_Light_T2_E2/ derived from the display name.

Study: PVL POD3 Group
The animals undergoing 60% PVL surgery. Surgeries were all performed in room E040a, WKFZ in the S1 area "Kleintier MRT". Post surgery holding was in room E040c directly next door and the final MRI in room E040a and room E040b.
All surgeries were performed by the same surgeon, Wei Weiwei from Prof. Dahmens group (P2).
The Control group underwent no surgery whatsoever (no sham). For the 4 groups POD1, 2, 3 and 5 MRI was performed on the respective day after surgery.

PRESS based fat quantification
Fat quantification of 5 liver lobes (RML, LML, LLL, RL, CL) During the MRI sesssion at least one PRESS voxel was placed in each of those liver lobes to acquire PRESS data for later fat analysis. Acquisitions were without water suppression, so the fat peaks are relatively small.
The quantification was performed using lcmodel. The original MRI data are part of the MRI session assays (data files uploaded). Here you can find the additional analysis and the output of ...

Perfusion Analysis of Control group
The MRI Perfusion technique is FAIR, so three maps were calulated:
Selective Inversion T1 Map Global inversion T1 map Perfusion Map (ml/min/100g)
This was performed once using the Paravision 6.0.1 Macro for Perfusion Evaluation and by using an in house matlab script.
The** original Perfusion Map from the Bruker scanner** are allready part of the original MRI data. You can find these in each of the Perfusion Exams in the Bruker reconstrcution folder pdata/ 1/ ...
