Artificial Thorax for MR Imaging Studies in Porcine Heart-Lung Preparations¹

¹ From the Department of Diagnostic Radiology, University Hospital Kiel, Arnold-Heller-Strasse 9, 24105 Kiel 1, Germany. Received July 26, 2001; revision requested September 12; revision received February 8, 2002; accepted February 28. Address correspondence to J.B. (e-mail: juergen.biederer@rad.uni-kiel.de).

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.
