A strategy for fast T2 relaxometry of the human lung is presented. Using radial TSE data acquisition, artifact-free separation of different T2 contrasts is possible by means of a novel iterative reconstruction technique based on Principal Component Analysis (PCA). It is shown that multislice T2 maps can be obtained in one single breathhold of 12s.
