Low-dose computed tomography with tin filtration for the diagnosis of sacroiliitis - our first experience

Publication at Faculty of Medicine in Pilsen, First Faculty of Medicine |


The aim of out study was to evaluate the effective radiation doses that patients received from low-dose computed tomography with tin filtration (Sn LDCT) of sacroiliac (SI) joints. We compared the doses from Sn LDCT with the doses from X-ray of SI joints and with the doses from standard CT examination of SI joints.

The Sn LDCT effective radiation doses were half that of the X-ray and decimal that of the standard CT. Sn LDCT does not burden the patient with excessive radiation.
