3D CAIPIRINHA SPACE permits the acquisition of 4-fold accelerated, high quality data sets and has been shown to be feasible for efficient 3D MRI of the knee; however, the clinical application has not been demonstrated. We report the performance of 3D CAIPIRINHA SPACE MRI for the diagnosis of internal derangement of the knee in children and adolescents using arthroscopy correlation as the standard of reference. 3D CAIPIRINHA SPACE enables clinically feasible isotopic 3D MRI of the knee in children and adolescents with an acquisition time of 10 min and high accuracy for the diagnosis of meniscal, ligamentous and cartilage abnormalities.
