生理惰性全氟化气体可用于核磁共振(核磁共振)肺通气成像。由于气体中的核浓度低于组织中的浓度,因此必须对来自大气体体积的信号进行积分,以产生可接受的图像质量。在一系列模型研究之后,已经进行了初步的犬类研究,使用了可呼吸的CF4和O2混合物。所得到的图像已经与Xe通风扫描进行了比较。此外,使用模体对全氟化溶液进行成像。对实验结果进行了描述,并对该技术的发展前景进行了展望。
: Physiologically inert perfluorinated gases may be used for lung ventilation imaging by Nuclear Magnetic Resonance (NMR). Because the nuclear concentration in the gas is lower than in tissue, signals from large gas volumes must be integrated to produce an acceptable image quality. After a series of phantom studies, preliminary dog studies have been carried out, using breathable mixtures of CF4 and O2. The resulting images have been compared with Xe ventilation scans. Furthermore, perfluorinated solutions were imaged using phantoms. The results are described and the future potential of the technique discussed.
