Table 21 Recommendations for CMR in the guidelines on the diagnosis and treatment of aortic diseases

Recommendations on diagnostic work-up of acute aortic syndrome

In stable patients with a suspicion of acute aortic syndrome (AAS), the following imaging modalities are recommended (or should be considered) according to local availability and expertise: CT (1C), MRI (1C), TOE (IIa C)

I

C

In case of initially negative imaging with persistence of suspicion of AAS, repetitive imaging (CT or MRI) is recommended

I

C

In case of uncomplicated Type B aortic dissection (AD) treated medically, repeated imaging (CT or MRI) during the first days is recommended

I

C

Recommendations on the management of intramural haematoma

In uncomplicated Type B intramural hematoma (IMH), repetitive imaging (MRI or CT) is indicated

I

C

Recommendations on management of penetrating aortic ulcer

In uncomplicated Type B penetrating aortic ulcer (PAU), repetitive imaging (MRI or CT) is indicated

I

C

Recommendations for the management of aortic root dilation in patients with bicuspid aortic valve

Cardiac MRI or CT is indicated in patients with bicuspid aortic valve (BAV) when the morphology of the aortic root and the ascending aorta cannot be accurately assessed by TTE

I

C

In the case of aortic diameter > 50 mm or an increase > 3 mm/year measured by echocardiography, confirmation of the measurement is indicated, using another imaging modality (CT or MRI)

I

C

Recommendations for follow-up and management of chronic aortic diseases

Contrast CT or MRI is recommended, to confirm the diagnosis of chronic aortic dissection

I

C

For follow-up after (T)EVAR in young patients, MRI should be preferred to CT for magnetic resonance compatible stent grafts, to reduce radiation exposure
