Both single-photon emission computed tomography (SPECT) and positron emission tomography (PET) scans provide volumetric information, which can be used to identify the surface of ventilated or perfused lungs. Because the outer surface of the lung is apposed to the rib cage and diaphragm, the configuration of the diaphragm and rib cage can also be determined by these methods. Both techniques offer poor spatial and temporal resolution and there are no published data in which they have been used to analyze respiratory muscle function.
