Article Synopsis
- Previous studies show that many healthcare providers overestimate the risks of radiation from imaging during pregnancy, leading to a reluctance to perform necessary imaging, even when it could greatly benefit patient care.
- This study aimed to assess current knowledge and confidence levels regarding imaging pregnant patients among various medical specialists through an anonymous survey, including radiologists and OB/GYN providers.
- The survey results revealed a general correct response rate of 68.5% across 18 questions, highlighting significant variability in knowledge, with some questions showing low correct response rates and most respondents feeling only "fairly" confident in their imaging decisions.

Purpose: When discussing radiation risks for patients who undergo many CT examinations, some question the risks, believing that most of these patients are already very sick and likely to die within a few years, thus negating worry about radiation risk. This study seeks to evaluate the validity of this notion.
Methods: In this retrospective single large-hospital study, patients who received CT exams in 2013 were sorted into four cumulative effective dose (CED) groups: Group A (>0 to <10 mSv), Group B (10 to <50 mSv), Group C (50 to < 100 mSv), and Group D (≥100 mSv).
The article reviews the historical developments in radiation dose metrices in medical imaging. It identifies the good, the bad, and the ugly aspects of current-day metrices. The actions on shifting focus from International Commission on Radiological Protection (ICRP) Reference-Man-based population-average phantoms to patient-specific computational phantoms have been proposed and discussed.
