Perfusion mapping using color-coded parametric images of pediatric abdominal tumors extends the diagnostic techniques currently available. We provide first proof of the possibility of integrating functional information into 3D MR images in children. Monitoring the treatment of nephroblastoma and surgical planning for pediatric embryonal tumors represent potential applications of this technique.

The developed software permits an objective and quantitative analysis of regional lung ventilation in absolute physical units. The clinical significance of the parameters, however, has to be determined in larger clinical studies. The software may become valuable in grading and following pulmonary function as well as in monitoring any therapy.

Partial parallel image acquisition can assess the perfusion of the lungs at high temporal resolution. The perfusion is slightly higher on the right than on the left. The signal increases faster and has a higher peak in the dorsal lung regions.
