Tungsten Alloy SPECT Syringe Shield

1. What’s Tungsten Alloy SPECT Syringe Shield?
Tungsten alloy SPECT syringe shield is portable hand shielding component used during radiopharmaceutical injection in Single Photon Emission Computed Tomography (SPECT) nuclear medicine, primarily for radiopharmaceuticals such as Tc-99m. CTIA’s tungsten alloy SPECT syringe shield uses tungsten’s high density and high atomic number to effectively attenuate 140 keV gamma rays emitted by Tc-99m, accommodates different syringe sizes, and reduces radiation exposure to operators’ hands through a compact shielding structure.

2. Features of CTIA’s Tungsten Alloy SPECT Syringe Shield
(1) Effective, Lightweight Shielding: Density of 16.7–18.8 g/cm³ and good attenuation of 140 keV γ-rays, with thinner shielding structures reducing the burden of hand-held operation under required protection levels.
(2) Compact, Portable Structure: High material density for effective shielding within limited space, helping reduce overall sleeve size for hand-held operation during SPECT radiopharmaceutical injection.
(3) Convenient, Visible Operation: Optional lead glass viewing windows or sliding windows for observing syringe graduations and medication status, with locking structures for improved syringe fixation.
(4) Durable, Stable Performance: High mechanical strength, corrosion resistance, and dimensional stability for repeated syringe loading and removal and frequent operation in SPECT nuclear medicine.
(5) Lead-Free, Easy Cleaning: Lead-free material without lead contamination concerns, with precision polishing and easy-decontamination surface treatment for routine cleaning, disinfection, and repeated use.

3. Applications of CTIA’s Tungsten Alloy SPECT Syringe Shield
(1) SPECT Imaging: Injection protection for Tc-99m-labeled agents such as ⁹⁹ᵐTc-MDP and ⁹⁹ᵐTc-MIBI during radiopharmaceutical administration before SPECT examinations.
(2) Nuclear Medicine Drug Dispensing: Localized radiation shielding during radiopharmaceutical loading and syringe preparation in hot cells, dispensing areas, and similar environments.
(3) Clinical Nuclear Medicine: Radiopharmaceutical injection in nuclear medicine outpatient departments, wards, bedside settings, and other environments involving frequent radiopharmaceutical handling.
(4) SPECT/CT Examination: Portable hand radiation protection during radiopharmaceutical injection for SPECT/CT examinations.
(5) Research and Clinical Trials: Experimental research, clinical trials, and related administration procedures involving SPECT tracers and other single-photon radiopharmaceuticals.
