Description Of Tungsten Alloy MR Syringe Shield

The Tungsten alloy MR syringe shield is a high-density (16.5-19.0g/cm³) tungsten alloy medical device that falls under the domain of nuclear medicine as a means of providing radiation protection during the medical injection of radioactive drugs, for example, fluorine-18-labeled FDG. It is used as a protective measure against the exhaust radiation of volatile radioactive substances that could be emitted during the procedures and/or operations. The core purpose is to avoid the ash of radioactive particles of the volatile radioactive substances through the Tungsten alloy's high atomic number and high-density virtues.

The injection of radiopharmaceuticals sets off a chain of events that the Tungsten alloy shield greatly attenuates. These include the emission of radioactive particles, such as gamma rays, and the attempt to penetrate using physical barriers and energy-sapping techniques. Radiation shielding is ideal with the dense dimensions of tungsten alloys. Their shielding performance is determined by the compounded action of the high-density material and the radiation photons and particles interacting, thus lowering the radiation dose and level for the operators.

The shield has been developed and integrated in such a way that it acts as an outer wall of the syringe, providing another layer of protection during injections. It takes into account ease of use and protective measures simultaneously. It prevents medical personnel from putting their hands directly on the syringe, which contains radionuclides, and at the same time, it reduces the chances of radiation leakage during the transfer of radioactive drugs through radiation attenuation material of the shield itself.

The use of tungsten alloy MR syringe shields has markedly enhanced the safety surrounding the processes involved in diagnosing and treating nuclear medicine. It eliminates excessive radiation and improves operational workflows, so it acts in the best interest of the medical personnel and patients at the same time while maintaining the captive volume and stability of the radioactive drugs during injection, aiding the steps in evolving nuclear medicine technology more safely and efficiently.

Features Of Tungsten Alloy MR Syringe Shield

1. High density and strong shielding performance: Tungsten alloy is super dense (16.5-19.0 g/cm³) and is extremely effective at blocking radioactive particles and radiation (like gamma rays and X-rays). For instance, an alloy shield with a thickness of 9mm can lower the radiation intensity of FDG F-18 to 88% of the original value.

2. Environmentally friendly and non-toxic: In comparison to lead, tungsten alloy is a non-toxic material that does not cause pollution to the human body or the environment.

3. Strong durability: It retains a high mechanical and dynamic strength, toughness, deformation resistance, and damage resistance suitable for repeated use.

4. Humanized design: Markings on the outer layer are inscribed with "MR safety," which prevents mix-ups; The applied embedded lead glass window permits unobstructed view, aiding easy observation of the medicament in the syringe. Besides, the guard cover also features a protective locking mechanism that serves to firmly fix the syringe in position.

5. Reduced dimensions and low weight: Tungsten alloy shields are lighter and thinner than traditional lead shields while providing the same level of protection.

6. Much more versatile: Adapts to most common volumetric syringes used in medicine (1cc, 2cc, 5cc, etc.) to suit multiple medical situations.

Applications Of Tungsten Alloy MR Syringe Shield

In the PET/CT scan, safety precautions are taken for medical personnel through the use of radioactive medications such as 18F-FDG. The transport and storage of radioactive drugs is done with tungsten alloy radiation shields since they effectively limit radiation leakage, protecting both the transport workers and the environment. In this case, it is done to safeguard the researchers from the manipulative work with radioactive isotopes in the nuclear medicine laboratories.
