Abstract

The bronchial circulation provides the lung with an oxygenated blood supply, derived from the aorta, whose primary purpose under normal conditions is thought to be nourishment of the airway walls +Guyton, 1996-. However,the study of the bronchial circulation and its development is particularly important with regard to lung tumors whose blood supply is via the bronchial circulation rather than the pulmonary circulation +Hirsch, 2001, Ohta, 2002-. Thus, we have developed a rat model of bronchial circulation angiogenesis,induced by complete occlusion of the left pulmonary artery. We have been observing the resulting perfusion changes in the left lung using dual-modality SPECT/micro-CT imaging. The initial objective of this study is to develop the necessary imaging system, protocol, and analysis methods for determining the time course of this angiogenesis, with the subsequent goal of using this approach to study the particular angiogenic mechanisms that might be involved.
