目前国内99TcmRBC的制备较普遍地采用体内标记法,标记过程简单,但标记率不高。我科自1988年以来一直采用体外标记法[1],标记率高,图像质量稳定,但标记过程较复杂,需准备无菌玻璃器皿,并保持体外标记操作的无菌条件,难于推广应用。为此,我们参照美国
At present, the preparation of 99Tcm-RBC is more commonly used in vivo labeling method, the labeling process is simple, but the labeling rate is not high. Our department has been using the in vitro labeling method since 1988 [1]. The labeling rate is high and the image quality is stable. However, the marking process is complicated. Sterile glassware needs to be prepared and aseptic conditions for in vitro labeling operations are maintained, making it difficult to popularize and apply. For this reason, we refer to the United States
