Description  Of Tungsten PET MR Syringe Shield

The Tungsten PET MR Syringe Shield (or injection shield) is an essential protective apparatus used by the nuclear medicine department for the radionuclide injection procedure in order to ionizing radiation. Its main purpose serves as a protective barrier for the injection of radioactive pharmaceuticals (e.g., Tc-99m, FDG F-18, etc.) to ensure the operator is completely isolated from the radiation source during drug administration or radiotherapy.

The tungsten PET MR syringe shielding is essential equipment for nuclear medicine treatments and PET/SPECT imaging to protect the occupational radiation exposure of medical staff. The combination of "actively radiation source shielding" and "operating procedures enhancing" features not only minimizes exposure during use but also streamlines the overall diagnosis and treatment, enabling the medical staff to efficiently perform radiopharmaceutical injections within a safe, controlled environment.

Tungsten PET MR syringe shield is now the primary device for radiation safety shielding in nuclear medicine because of its exceptional proactive operational efficiency and protective capabilities, facilitating high-precision medicine alongside occupational health.

Features Of Tungsten PET MR Syringe Shield

1. High density and extraordinary shielding:

The tungsten alloy's density surpasses that of other metals, standing at 16.5 to 19.0 g/cm³, which is around 60% greater than lead. It can effectively protect against whatever high-energy nuclear radiation, which includes FDG, a substance commonly utilized during PET imaging. A shield made of tungsten alloy, which is approximately 9mm thick, can attenuate 88% of FDG F-18 emission radiation.

2. Non-magnetic and MRI friendly:

Tungsten alloy does not interfere with 3T MRI gadgets, hence aids in non-magnetic material requirements and will not distort the image.

3. Ergonomic design:

Shielding parts are usually combined with protective glasses of high-density lead glass to allow easy gazing at the dosages of medication held in the syringe. A white reflecting background is used to enhance further the observation of scales and medications and thumb screws fasten the syringes during operations to keep it stable.

4. Eco-friendly and non-toxic:

For a long time, lead materials were used due to their high strength. However, tungsten alloy is more eco-friendly and non-toxic. Tungsten alloy, on the other hand, is not harmful and can be called environmentally friendly.

5. Disinfection friendly:

It fulfills the standards for hygiene in medical settings due to its smooth surface, which can be easily wiped down with sterilizing alcohol, disinfecting wipes.

6. Reduction in Size and Weight:

Compared to lead shielding components, tungsten alloy shielding components achieve the same shielding effect with much less volume and weight, thus are less cumbersome to operate and handle.

Applications Of Tungsten PET MR Syringe Shield

In PET/MR imaging, tungsten syringe shielding is used to inject high-energy isotopes such as FDG-F18 to ensure the injection process is safe without affecting the imaging quality. Tungsten is a non-magnetic material and is suitable for PET/MR imaging environments, and does not interfere with imaging equipment.
