This review guides readers through the selection and setup of standardized noncardiac chest MRA protocols, including contrast-enhanced MRA (CE-MRA) and noncontrast MRA (NC-MRA), sequences that can be used in a variety of clinical situations. After reviewing basic principles described in the first three tutorials in this series on CE-MRA and NC-MRA, this online presentation details the use of MRA in specific clinical scenarios: thoracic aortic aneurysm, aortic dissection, congenital heart disease, vasculitis, central veins, and pulmonary embolus. Tips and tricks for optimization of the sequences, image acquisition, and image interpretation are provided. This module is the fourth in a series created on behalf of the Society for Magnetic Resonance Angiography (SMRA), a group of researchers and clinicians who are passionate about the benefits of MRA but understand its challenges. The full digital presentation is available online. ©RSNA, 2022.
