1.
In this paper we present a modified algorithm of CT-Based attenuation correction for PET/CT Scanners in the presence of contrast agent,which can lead to unbiased result for the estimation of emission activity in these cases.
PET/CT扫描一般直接将CT透射扫描数据用于PET发射扫描的衰减校正,但是在有口服造影剂使用的场合,常规的衰减校正算法对PET扫描结果会带来约20%的正偏差。
2.
The CT option can make attenuation correction to SPECT image or coincidence PET image, which makes the image of nuclear medicine closer to the real situation of distribution of radioactive nuclide in patients.
该CT能完成对SPECT图像或符合线路PET图像的衰减校正,使核医学图像能更接近的反映核素在人体内的真实分布情况。
3.
Some new advances of research and clinical study on PET/CT were summarized briefly,including the choice of crystals,development of CT,radiotherapy plan,attenuation correction with CT,respiratory motion and CT contrast induced artifacts.
本文简要介绍PET/CT有关的几个技术问题和临床应用方面的新进展,如晶体的选择、CT技术进展、放射治疗、衰减校正、呼吸运动及CT造影剂的影响等。

补充资料:高压荧光灯用荧光粉
分子式:
CAS号:
性质:高压荧光灯中涂上Eu3+激活的钒酸钇或钒磷酸钇(YVO4:Eu,Y(V,P)O4:Eu),可提高光效,改善显色性,增加了灯中的红色比和显色指数。YVO4白色立方晶体耐温度猝灭,发光效率高,传递效率大,高压荧光汞灯主要用于街道,厂房和场地照明。
