Artificial thorax for MR imaging studies in porcine heart-lung preparations.

A double-walled magnetic resonance (MR) imaging-compatible container with a flexible diaphragm was designed to hold freshly excised porcine heart-lung preparations. The saline contents simulate MR signal of an actual chest wall. Continuous evacuation keeps the lung inflated. A variety of experiments with different imaging modalities, including angiography, under close to in vivo conditions are feasible. Access to bronchial system and lung vessels allows for various studies.
