This investigation's aim was to study a noninvasive method for determining the ventilation of the nasal sinuses. For this purpose, different insufflation techniques using xenon 133 were tried, along with different scintillation camera techniques. Xenon 133 gas was used for insufflation in the nose and sinuses, and the half-time of the washout curves was determined with the aid of digital scintillation cameras, one of which was capable of dynamic tomography. The tomographic procedure was superior because it made it possible to study the washout from the ethmoidal/sphenoidal sinuses as well. The washout was followed for up to 150 minutes. Great variations in washout were found between different sinuses and also in the same sinus over time. The single photon emission computed tomography (SPECT) technique, which is easy to perform and gives a limited absorbed dose to the patient, seems promising for the future evaluation of sinus ventilation and ostial function.
本研究的目的是探索一种用于测定鼻窦通气的非侵入性方法。为此，尝试了使用氙133的不同吹入技术以及不同的闪烁相机技术。将氙133气体吹入鼻腔和鼻窦，并借助数字闪烁相机测定洗脱曲线的半衰期，其中一台相机能够进行动态断层扫描。断层扫描程序更具优势，因为它还能够研究筛窦/蝶窦的洗脱情况。洗脱过程持续观察长达150分钟。发现不同鼻窦之间以及同一鼻窦随时间的洗脱情况存在很大差异。单光子发射计算机断层扫描（SPECT）技术操作简便，且给患者的吸收剂量有限，似乎在未来鼻窦通气和窦口功能评估方面很有前景。
