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.

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…

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 the radioactive isotope yttrium-90 that is inserted into tiny glass beads and injected into the tumor's blood supply.

Radioembolization is a minimally invasive outpatient procedure that involves the precise placement of microscopic radioactive spheres (microspheres) via a small catheter placed in directly in blood vessels that supply a tumor in the liver.

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.

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.

Yttrium-90 (90 Y) microsphere radioembolization is a promising treatment modality that has emerged for the management of patients with liver cancer. Liver tumours, both primary and metastatic, form a large proportion of solid tumours with a variety of therapeutic options.

2019年2月5日 · Radioembolization gains continuous traction as a primarily palliative radiation treatment for hepatic tumours. A form of nuclear medicine therapy, Yttrium-90 containing microspheres are catheter guided and injected into the right, left, or a …

2023年9月12日 · Yttrium-90 (Y90) radioembolization, or selective internal radiotherapy, is an alternative treatment option for liver cancer that can’t be cured with typical treatments. The...
