The aim of this project was to evaluate the feasibility of simultaneous imaging of tumor perfusion with multiple small animals on a 1.5 T clinical scanner. A homebuilt 4-channel receive array was used for this experiment. The examined small animals were nude mice bearing induced squamous cell carcinoma. The DCE-MRI delivered analyzable results. This was possible without sacrificing image quality in comparison to single animal imaging with highest possible resolution depending on gradient field strength.
