title: [Evaluation of imaging before lung volume reduction surgery for pulmonary emphysema; fused image of multi-detector row computed tomography and scintigram].
abstract: Lung volume reduction surgery (LVRS) is performed as surgical therapy for severe pulmonary emphysema. In assessing diagnostic imaging indications, emphysematous change is the strongest in the thoracic computed tomography (CT), while the accumulation decrease is most remarkable in ventilation scintigram and lung perfusion scintigram. Preoperative evaluation of imaging using multidetector-row CT (MDCT) and scintigram were performed, and the multiplanar reconstruction (MPR) image of the MD CT and the single photon emission CT (SPECT) image of the scintigram were fused by the workstation. It was possible to evaluate the excision and the range of LVRS easily by looking at the fused image, and it was useful in deciding on the surgical approach. It is believed that accurate, comprehensible imaging information contributed to an improvement in the surgical outcome of LVRS.
