Interventions

Group 1: The patients have a clinical indication for magnetic resonance angiography (MRA) of the thoracic aorta. For the MRA examination, the patient is positioned in a magnetic resonance imaging (MR

Inclusion criteria

Inclusion criteria: - Clinical indication for magnetic resonance angiography (MRA) of the thoracic aorta. - Written informed consent.

Exclusion criteria

Exclusion criteria: - Inability to provide informed consent. - Age <18 years. - Patients for whom the additional examination time would, in the opinion of the investigator or the patient, constitute an unacceptable burden. - Claustrophobia. - Non-MRI-compatible implants or metallic foreign bodies. - Pregnancy. - Known hypersensitivity or contraindication to gadolinium-based contrast agents. - Chronic kidney disease, Stage V (estimated glomerular filtration rate [eGFR] =15 mL/min/1.73 m²).
