ClearView Radiation Shielding – Vial Shield

ClearView Radiation Shielding is being used in diagnostic imaging and therapies in over 500 hospitals with various products for Theranostics (in use or under development) as an alternative to lead. 

Therapeutic Diagnostic
Iodine (I) -131 (mIBG, Iopofosine, Azedra, etc.) Gallium (Ga) – 68 (PSMA, Dotatate, Illicix)
Lutetuim (Lu)-177 (Pluvicto, Lutathera, etc.) Fluorine (F) -18 (FDG, PYLARIFY, etc.)
Copper (Cu) -67 (SECuRE, etc.) Copper (Cu) -64 (SAR-bisPSMA)
Actinium (Ac) -225 (Lintuzumab, PSMA, etc.) Technetium (Tc)-99m (Neurolite, Draximage, etc.)
Lead (Pb) -212 (DOTAMTATE, VMT01) Indium (In) -111
Yttrium (Y) -90 (SIR-Spheres, TheraSphereTM , etc.) Iodine (I) -123
Radium (Ra) -223
Samarium (Sm) -153

In Theranostics, vial shields are used to store radioisotopes and sometimes administered doses with gravity method of infusion. This requires shielding the nuclear medicine technologist administering a dose. ClearView Vial Shield can be used for Ac-225 PSMA, I-123 and I-131 mIBG therapies, Lutathera (Lu-177) therapies for Neuroendocrine Tumor Treatment, FDA approved PluvictoTM (lutetium Lu 177 vipivotide tetraxetan or 177Lu-PSMA-617) for the treatment of prostate-specific membrane antigen–positive metastatic castration-resistant prostate cancer (PSMA-positive mCRPC). Using lead vial shields has led to incomplete infusion of radionuclides such as Lu-177 which is used to treat Neuroendocrine Tumors and PSMA Therapies. The ClearView Vial Shield provides significant workflow and operational advantages over available products. Lead vial shields are heavy and RoHS restricted.

The ClearView RS® Vial Shield fits vials up to 50 ml, including those supplied by AAA (manufactures of Lutathera). There have been cases where heavy, opaque lead pigs have not been the most ideal shields for Lutathera infusion. To avoid incomplete infusion and to easily monitor the volume of radiopharmaceutical (here Lu177) administered, a clear shield has been developed to house a Lu-177 vial using ClearView Radiation Shielding.
