Assessment of scatter radiation dose received by comforters and carers during digital breast tomosynthesis mammography.

Introduction: Mammographic imaging can cause considerable stress and anxiety for some patients and may require someone to remain in the room during the procedure to provide both physical and emotional support. As such, these comforters and carers (C&C) are exposed to ionising radiation. Limited evidence is available stating the radiation dose received during a digital breast tomosynthesis (DBT) examination.

Radiation exposure from radiological procedures in liver transplant candidates with hepatocellular carcinoma.

Purpose: Candidates for liver transplantation (LT) with hepatocellular carcinoma (HCC) undergo a large number of diagnostic and interventional radiology procedures. A significant proportion of such procedures involve ionizing radiation with increased lifetime risk of cancer. The objective of our study was to review LT candidates with HCC to quantify ionizing radiation doses from different radiology procedures performed at a single transplant center.

SCATTER RADIATION INTENSITIES IN HORIZONTAL AND VERTICAL PLANES ABOUT DIGITAL BREAST TOMOSYNTHESIS SYSTEM.

Digital breast tomosynthesis (DBT) is a main imaging modality for breast imaging. However, shielding calculations for DBT are commonly based on previous technology with softer beam spectra. In addition, shielding calculations often assume some patient attenuation is provided in locations to the posterior of the patient but without quantification of this attenuation.
