Cesium-131 permanent seed brachytherapy:

01.11.2011· Cesium-131 (131 Cs) radioactive seed has recently been introduced into clinical practice (Isoray, Richmond, WA) for permanent seed implant for cancer. The titanium tube has an outer diameter of 0.8 mm with a wall thickness of 0.05 mm and thus an inner diameter of 0.7 mm. The center X-ray marker is a 0.25 mm diameter gold wire. The wire is surrounded by a glass and ceramic tube with

Resection and permanent intracranial brachytherapy using

Cesium-131 (Cs-131) radiation sources were embedded in modular col-lagen carriers positioned in the operative bed on completion of resection. The Cox proportional hazards model with this treatment as a predictive term was used to model its effect on time to local tumor progression. RESULTS Nineteen patients (median age 64.5 years, range 50–78 years) with 20 recurrent, previously irradiated

Cesium-131 (Cs-131)

The half-life of Cs-131 is 9,7 days. It decays by electron capture emitting photon radiation in the X-ray range (29.5 - 33.5 keV). The optimal combination of its half-life and radiation energy makes Cs-131 an attractive radioisotope for brachytherapy of malignant tumors.

Cesium Cs-131 (Concept Id: C2986852)

An unstable radioisotope of cesium (Cs) with radiocytotoxic application. Cs-131 is a gamma photon-emitting radionuclide with high energy and a relatively short half-life of 9.7 days. When used in prostate brachytherapy, Cs-131 demonstrated advantages over other commonly used isotopes.
