IRCT20180730040642N1 IRCT 2018-11-15 Artesh University of Medical Sciences Effect of high-pass radiation shield on image quality of CT scan Assessment of a high-pass radiation shield on image quality in patients undergoing computed tomography (CT) 2018-10-23 anticipated 160 Complete https://irct.ir/trial/33007 interventional Randomization: Not randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Prevention, Blinding description: The CT images will be analysed and interpreted by radiologists. To have unbiased interpretation, the radiologists will be blinded by removing the image of shield from the reconstructed images. N/A Protection of radiosensitive organs against radiation in CT scan. Intervention 1: Intervention group: high-pass radiation shield will be placed over breasts, thyroid, eyes, testes, and ovaries of the patients undergoing thoracic, head and neck, and stomach and pelvis CT examination. The high-pass radiation shield was constructed by the researcher of the current study and tested on phantom recently. during imaging, the shield will be positioned over a foam of 3 cm width over the target organs of the patients and will not have any contact with the patient's body. the shield will be used once on every patient and the patients do not need any education about it. Intervention 2: Control group: Patients will undergo routine CT imaging of head, neck or thorax and pelvis and stomach without any further action.
