Introduction: In angiography and especially in angioplasty, large amounts of X-rays are emitted to the patient’s body, which causes the patient to be exposed to a lot of radiation. Saba Shield is a type of highpass shield that was introduced recently. Moreover, its effectiveness in reducing the dose of patients during CT scan imaging has been investigated and confirmed. It seems that the use of Saba shield with optimal thickness can significantly reduce the dose received by patients in angiography and angioplasty. The aim of this study is to investigate the effectiveness of Saba Shield with Zn-Bi combination on reducing the dose received by patients and its effect on the quality of images in angiography and angioplasty.
Methods and Materials: One shield with dimensions of 60 x 40 cm and thickness of 0.04 mm equivalent to lead was prepared in order to investigate the efficiency of Saba shield with Zn-Bi combination in angiography and angioplasty. Angiography machine was used for radiation and CTDI phantom was used to simulate the patient’s body. Dosimetry using TLDs was performed on the CTDI phantom without shield and with shield.
Then, the values of dose reduction and image quality were examined. In order to check the quality of the image, according to the radiology experts, it was used in a double-blind manner.
Results: The findings of the present study showed that the use of Saba Shield with Zn-Bi combination in angiography and angioplasty has reduced the dose between 30 and 37% of the dose received by patients with moderate and acceptable image quality.
Discussion and Conclusion: Saba shield with Zn-Bi composition and thickness of 0.04 mm equivalent to lead can significantly reduce the dose received by the patients and it does not have a degrading effect on the quality of the images.
