BACKGROUND: @entity706 often presents as a large @entity5 at the time of diagnosis. Usually chest X-ray filming is the first imaging modality and it is used for routine follow-up during the course of the disease. A new and very fast @entity7994 technique has been developed at our center as an alternative. Results in three @entity1 with @entity706 during a pilot study are promising. PROCEDURE: After diagnosis the above @entity1 were additionally investigated in a 0.2 T low-field MR-scanner by a modified true FISP sequence (see text) with an acquisition time of 3.6-4.6 sec. Follow-up was performed by both, @entity7994 . After diagnosis the @entity1 , again, had both @entity7994 investigation for follow-up: one @entity1 2, one @entity1 3, and one @entity1 5 times. Images were evaluated and compared by two pediatric radiologists. RESULTS: Total investigation times for radiography and @entity7994 were comparable. The @entity5 was better visualized by @entity7994 on seven of nine images and gave additional information about the structure and the localization of the @entity5 as well as concomitant problems such as @entity2294 . CONCLUSIONS: True FISP @entity7994 may prove to be a good alternative to X-ray filming in the diagnosis and follow-up of @entity706 .

A fast magnetic resonance imaging technique for @entity1 with XXXX : work in progress.
