As stated in the preface, this monograph provides an anatomic-physiologic approach to lung scan interpretation. The anatomic and physiologic alterations in pulmonary circulation produced by various pathologic states is stressed throughout, and the lung scan is viewed as a means of capturing the image of regional pulmonary blood flow at a given instant.
There are five chapters. The first, on anatomy and physiology, is a fine presentation of pulmonary structures, surface anatomy, and pulmonary circulation. There is an excellent, understandable description of respiratory physiology including newer concepts, and the effect of physiologic alterations on the lung scan is illustrated. The second chapter considers the technology of obtaining a lung-scan image. It describes in an effective, simplified manner the advantages and limitations of various types of recording instruments and radioisotopes. The changes produced by bronchial and parenchymal disease on the lung scan are well described in the next chapter. The relationship
