钇90是较理想的治疗用 放射性核素，其 半衰期 为64h，辐射类型为纯β辐射 (0.9MeV)，可由90Sr-90Y 发生器 得到。 90Y主要用于制备 治疗用放射性药物。 国际上应用的90Y 微球 有两种 …

Yttrium-90 (90 Y ) is a radioactive isotope of yttrium. [2] Yttrium-90 has found a wide range of uses in radiation therapy to treat some forms of cancer. [3] Along with other isotopes of yttrium, it is sometimes called radioyttrium.

2023年7月14日 · Radioembolization is a type of transarterial therapy that strategically attacks liver tumors with localized, high doses of radiation. The treatment often is called Y-90. This refers to …

钇-90（Y-90）微球放射栓塞治疗技术是一种靶向肿瘤放射治疗，该项技术被广泛应用于肝脏恶性肿瘤的选择性体内放射治疗（SIRT）中，即在肝脏病灶处，通过靶向的大剂量高能量β辐射起到杀死癌细胞的目的，同时可以很…

2019年10月31日 · Radioembolization with Y90 is a minimally invasive procedure primarily used in the treatment of liver cancer. In contrast to most nuclear medicine applications, Y90 is therapeutic and designed to treat rather than simply diagnose.

钇90树脂微球治疗是 介入治疗 中的一员，也是被FDA批准，用于治疗不可切除的肝细胞性肝癌的选择性内放射治疗，属于精准放疗。 它的治疗原理是通过一次微创介入手术，将数百万个含有放射性Y90物质的树脂微球注射到肝脏肿瘤的滋养血管内，让微球进入病灶内部，利用其释放的β射线近距离杀死癌细胞。 钇90打的不是化疗药，打的是放射性同位素，这种同位素就像重磅的‘核弹’，通过肝脏血管打到肿瘤局部，进行局部引爆把肿瘤杀死，有了这种新的治疗武器，会有更多的肝 …

2023年10月3日 · Radioembolization is a type of transarterial therapy that strategically attacks liver tumors with localized, high doses of radiation. The treatment often is called Y-90. This refers to the radioactive isotope yttrium-90 that is inserted into tiny glass beads and injected into the tumor's blood supply.

Y90 radioembolization allows doctors to treat the cancer without removing large portions of the liver. Depending on the patient, treating hepatocellular carcinoma with Y90 radioembolization can: help cure the disease. help slow or stop the cancer’s progress and relieve symptoms.

Radioembolization is a minimally invasive procedure that combines embolization and radiation therapy to treat cancers in the liver. Tiny beads filled with a radioactive isotope are placed inside the blood vessels that supply a tumor.

2024年3月12日 · 钇‑90微球选择性内放射治疗（90Y‑SIRT）是治疗肝脏恶性肿瘤的重要手段之一。 自2022年1月我国首个钇-90微球注射液获批上市以来，经过两年多的临床大规模实践积累，规范性文件《钇‑90微球选择性内放射治疗肝脏恶性肿瘤规范化操作专家共识（2024版）》 [1]于近日正式发布。 本刊特邀 共识执笔专家之一、东南大学附属中大医院介入与血管外科朱海东教授，从共识制定背景和初衷、内容要点和亮点、推广落地和尚待解决问题这四个方面进行深度解读。 …
