Evidence-based radiology 5 years on-a single-centre review of image referral appropriateness.

Background: The iRefer guidelines provide evidence-based recommendations on imaging and are designed to facilitate appropriate referrals and limit unnecessary radiation exposure. In 2017, a review at this institution assessed the appropriateness of imaging referrals. This study provides an update 5 years later on the referral appropriateness and aims to assess what impact the previous review has had on referral appropriateness.

E-scooter-related imaging: a new emerging high-energy trauma patient.

Objectives: To quantify the volume and nature of radiological imaging performed for e-scooter related trauma presentations in a tertiary referral centre and to identify common radiological pattern of injuries.

Methods: Our study received institutional review board approval. We retrospectively reviewed all anonymised radiological imaging studies performed in our institution for the term 'scooter' or 'e-scooter' between July 2020 and July 2021.

Validating the safety of low-dose CTPA in pregnancy: results from the OPTICA (Optimised CT Pulmonary Angiography in Pregnancy) Study.

Background: Pulmonary embolism (PE) is a leading cause of pregnancy-related mortality. CT pulmonary angiogram (CTPA) is the first-line advanced imaging modality for suspected PE in pregnancy at institutes offering low-dose techniques; however, a protocol balancing safety with low dose remains undefined. The wide range of CTPA doses reported in pregnancy suggests a lack of confidence in implementing low-dose techniques in this group.

Breast Shielding Combined With an Optimized Computed Tomography Pulmonary Angiography Pregnancy Protocol: A Special Use-Case for Shielding?

Objectives: To determine the impact of breast shields on breast dose and image quality when combined with a low-dose computed tomography pulmonary angiography (CTPA) protocol for pregnancy.

Methods: A low-dose CTPA protocol, with and without breast shields, was evaluated by anthropomorphic phantom and 20 prospectively recruited pregnant participants from January to October 2019. Thermoluminescent dosimeters measured surface and absorbed breast dose in the phantom and surface breast dose in participants.
