Abstract:
With modern technological advances in imaging, radial scars are more frequently encountered in clinical practice. The management of radial scars remains challenging due to associated upgrade to malignancy at excision. Contrast-enhanced mammography (CEM) has a similar sensitivity compared to MRI in addition to lower cost, better availability and fewer contra-indications. CEM is reported to have an overall excellent negative predictive value for malignancy. In this study, imaging of 55 patients with a core biopsy diagnosis of radial scar since the introduction of CEM into local practice was reviewed. Nine patients underwent CEM as part of their diagnostic work-up and these appearances are presented as a pictorial essay to demonstrate enhancement patterns of radial scars on CEM in this cohort and consider how this knowledge may influence management.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
