Efficacy of breast shielding during head computed tomography examination

Zalokar, Nika (avtor), Mekiš, Nejc (avtor)

Background. Female breasts are exposed to scattered radiation regardless of not being included in the primary field during head CT. This study aimed to investigate whether the use of lead shielding is beneficial in dose reduction to the breasts during head CT. Patients and methods. The study was performed in two different hospitals on two different CT units and included 120 patients. Half of the measurements (n = 60) was conducted without the use of lead shielding and the other half (n = 60) with the use of lead shielding of 0.5 mm equivalent thickness. Results. Significant skin dose reduction to the breasts during head CT in both hospitals with the use of lead shielding was discovered; 81% (338.2 ± 43.7 μGy to 64.3 ± 18.8 μGy) in Hospital A and 74% (from 253.1 ± 35.1 μGy to 65.3 ± 16.9 μGy) in Hospital B. Conclusions. Considering the assumed carcinogenic effect of low doses of radiation, high frequency of the head CT scans and the significant reduction of radiation doses to the highly radiosensitive breasts, the use of lead shielding is highly recommendable.
