用SPECT断层影像定量测定CBF和rCBF是近年来发展起来的新技术,由于它可在三维影像的基础上精细地定位和定量,引起广泛的重视。但以往使用的单光子脑血流显像剂是用~(123)I标记的,无论价格和来源方面都不够理想。为此,我们尝试用新的脑血流显像剂定量测定CBF和rCBF,本文仅就定量测定特殊技术的研究及结果报道如下。 The quantitative determination of CBF and rCBF by SPECT tomography is a new technique developed in recent years. Because it can be finely localized and quantified on the basis of three-dimensional images, it has attracted a great deal of attention. However, single-photon cerebral blood flow imaging agents used in the past were marked with ~ (123) I, which were not ideal in both price and origin. To this end, we try to quantify CBF and rCBF with a new cerebral blood flow imaging agent, the research and results of this article only on the quantitative determination of special techniques are reported below.
