Blade DCE MRI - Towards Renal Perfusion Measurements with reduced Motion Artifacts

F. Lietzmann, F. Zöllner and L. Schad

Proceedings 17th Scientific Meeting, International Society for Magnetic Resonance in Medicine, Honolulu,, p.4137

The major problems in renal DCE MRI are, like in the entire field of abdominal imaging, motion artifacts that primarily arise from the patient´s respiration. Here, we present an approach utilizing Blade for DCE-MRI of the human kidney to suppress motion while keeping critical parameters like temporal and spatial resolution within acceptable limits. A saturation recovery pre-pulse was added to a conventional FLASH sequence to gain T1 contrast. We showed that the reduction of blade width, leading to a higher number of blades recorded for each image, correlates with a noticeable correction of the respiratory movement and hence will lead to less distorted signal time courses.
