description

Imaging of the lung with hyperpolarized 3He became a well known technique in the last decade. Being able to image ventilation and the microstructure of the lung an increase of SNR and a shortage of scan time is eligible. By using a 32-channel phased array the sensitivity was increased dramatically. High resolution 2D-images with a resolution of 1 × 1 mm2 having a 3 mm slice was realized, showing highly detailed images of the lung. By applying parallel imaging techniques the SNR could be increased and scan time was reduced drastically by using a 2D acceleration of R = 4 × 2 with a 3D-protocol covering the whole lung.
