Abstract:
Contrast media extravasation represents a not unusual problem in radiological practice. Incidence, patient-, and procedure-related risk factors, pathogenesis, and clinical manifestations of extravasation injuries are discussed with a review of recent literature, and a practical preventive approach is proposed. A diagnostic and therapeutic protocol, to be applied whenever contrast extravasation is detected, includes radiographic assessment of compartmentalization, antidote application, local care, and clinical follow-up; indications for surgical consultation and adverse event reporting are provided.

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

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...
