SPECT/CT with <sup>99m</sup>Tc-DTPA in a Patient with Persistent Complex Pneumothorax after Endobronchial Valve Placement
Ventilation-perfusion SPECT with or without CT using technetium 99m (<sup>99m</sup>Tc)-diethylenetriaminepentaacetic acid (DTPA) has been used to identify patterns typical of cardiopulmonary diseases, such as pulmonary embolism, pneumonia, heart failure, and obstructive lung disease. This case demonstrates the utility of a ventilation scan with SPECT/CT using <sup>99m</sup>Tc-DTPA for investigating the cause of a persistent complex pneumothorax in a patient with severe chronic obstructive pulmonary disease who recently underwent endobronchial valve placement. <b>Keywords:</b> CT-Spectral Imaging (Multienergy), SPECT/CT, Thorax, Lung <i>Supplemental material is available for this article.</i> © RSNA, 2024.
