MRI is the imaging modality of choice in the assessment of longstanding aortic disease in a patient who has chronic chest pain who is hemodynamically stable or for the evaluation of a chronic dissection.

*An MRI examination of the aorta will produce a three-dimensional reconstruction of the aorta, allowing the physician to determine the location of the intimal tear, the involvement of branch vessels, and locate any secondary tears.

*The disadvantage of the MRI scan in the face of aortic dissection is that it has limited availability and is often located only in larger hospitals, and the scan is relatively time consuming.

*Due to the high intensity of the magnetic waves used during MRI, an MRI scan is contraindicated in individuals with metallic implants. *In addition, many individuals develop [[claustrophobia]] while in the MRI scanning tube.

Overview

MRI is the imaging modality of choice in the assessment of longstanding aortic disease in a patient who has chronic chest pain who is hemodynamically stable or for the evaluation of a chronic dissection.

MRI

  • Magnetic resonance imaging (MRI) is currently the gold standard test for the detection and assessment of aortic dissection, with a sensitivity of 98% and a specificity of 98%.
  • An MRI examination of the aorta will produce a three-dimensional reconstruction of the aorta, allowing the physician to determine the location of the intimal tear, the involvement of branch vessels, and locate any secondary tears.
  • It is a non-invasive test, does not require the use of iodinated contrast material, and can detect and quantitate the degree of aortic insufficiency.
  • The disadvantage of the MRI scan in the face of aortic dissection is that it has limited availability and is often located only in larger hospitals, and the scan is relatively time-consuming.
  • Due to the high intensity of the magnetic waves used during MRI, an MRI scan is contraindicated in individuals with metallic implants.
  • In addition, many individuals develop claustrophobia while in the MRI scanning tube.

2022 ACCF/AHA/AATS/ACR/ASA/SCA/SCAI/SIR/STS/SVM Guidelines for the Diagnosis and Management of Patients With Thoracic Aortic Disease[2]

Recommendations for HTAD: Genetic Testing and Screening of Family Members for TAD Referenced studies that support the recommendations are summarized in the Online Data Supplement

Class I
1. In patients with TAD who have a pathogenic/likely pathogenic variant, genetic testing of at-risk biological relatives (ie, cascade testing) is recommended.6,10,11 In family members who are found by genetic screening to have inherited the pathogenic/likely pathogenic variant, aortic imaging with TTE (if aortic root and ascending aorta are adequately visualized, otherwise with CT or MRI) is recommended.(Level of Evidence: B-NR)

Recommendations for Aortic Imaging Techniques to Determine Presence and Progression of Aortic Disease Referenced studies that support the recommendations are summarized in the Online Data Supplement

Class I
1. In patients with known or suspected aortic disease, when performing CT or MR imaging, it is recommended that the root and ascending aortic diameters be measured from inner-edge to inner-edge, using an electrocardiographic-synchronized technique. If there are aortic wall abnormalities, such as atherosclerosis or discrete wall thickening (more common in the distal aorta), the outer-edge to outer-edge diameter should be reported(Level of Evidence: C-EO)

Recommendations for Imaging in Loeys-Dietz Syndrome

Class I
1. In patients with Loeys-Dietz syndrome and a dilated or dissected aorta and/or arterial branches at baseline, annual surveillance imaging of the affected aorta and arteries with MRI or CT is recommended(Level of Evidence: C-EO)

2. In patients with Loeys-Dietz syndrome, a baseline MRI or CT from head to pelvis is recommended to evaluate the entire aorta and its branches for aneurysm, dissection, and tortuosity.(Level of Evidence: C-LD)

Class IIa
1.In patients with Loeys-Dietz syndrome with-out dilation of the aorta distal to the aortic root or ascending aorta and without dilated or dissected arterial branches, surveillance imaging from chest to pelvis with MRI (or CT) every 2 years is reasonable, but imaging may be more frequent depending on family  history.(Level of Evidence: C-EO)

2.In patients with Loeys-Dietz syndrome with-out dilation of the cerebral arteries on initial screening, periodic imaging surveillance for cerebral aneurysms with MRI or CT every 2 to 3 years is reasonable.(Level of Evidence: C-EO)

Recommendations for Inflammatory Aortitis: Diagnosis and Treatment of Takayasu Arteritis and GCA Referenced studies that support the recommendations are summarized in the Online Data Supplement

Class I
1.In patients with large vessel vasculitis (LVV), prompt evaluation of the entire aorta and branch vessels with MRI or CT, with or without 18F-FDG positron emission tomography (FDG-PET), is  recommended.(Level of Evidence: C-LD)

Recommendations for Long-Term Surveillance Imaging After Aortic Dissection and IMH Referenced studies that support the recommendations are summarized in the Online Data Supplement

Class I
1. In patients who have had an acute aortic dissection and IMH treated with either open or endovascular aortic repair and have residual aortic disease, surveillance imaging with a CT (or MRI) is recommended after 1 month, 6 months, and 12 months and then, if stable, annually thereafter.(Level of Evidence: B-NR)

2. In patients who have had an acute aortic dissection and IMH that was managed with medical therapy alone, surveillance imaging with a CT (or MRI) is recommended after 1 month, 6 months, and 12 months and then, if stable, annually thereafter.(Level of Evidence: B-NR)


2014 ESC Guidelines on the Diagnosis and Treatment of Aortic Diseases (DO NOT EDIT)[3]

Diagnostic Value of MRI in Aortic Dissection

Class I
"In stable patients, computed tomography or magnetic resonance imaging are the recommended imaging studies. prefered modality is chosen according to local availabilty or expertise. (Level of Evidence: C)"
"In case of initially negative imaging study, repetitive imaging study (including CT or MRI) is recommended if the suspicion for acute aortic syndrome is high. (Level of Evidence: C)"
"Repeated imaging study (including CT or MRI) is recommended in case of uncomplicated medially treated aortic dissection type B in the first few days of treatment. (Level of Evidence: C)"

2010 ACCF/AHA/AATS/ACR/ASA/SCA/SCAI/SIR/STS/SVM Guidelines for the Diagnosis and Management of Patients With Thoracic Aortic Disease (DO NOT EDIT)[4]

Screening Tests (DO NOT EDIT)[4]

Class I
"1. Urgent and definitive imaging of the aorta using transesophageal echocardiogram, computed tomographic imaging, or magnetic resonance imaging is recommended to identify or exclude thoracic aortic dissection in patients at high risk for the disease by initial screening. (Level of Evidence: B)"

Determining the Presence and Progression of Thoracic Aortic Disease (DO NOT EDIT)[4]

Class I
"1. For measurements taken by computed tomographic imaging or magnetic resonance imaging, the external diameter should be measured perpendicular to the axis of blood flow. For aortic root measurements, the widest diameter, typically at the mid-sinus level, should be used. (Level of Evidence: C)"

Genetic Syndromes (DO NOT EDIT)[4]

Class I
"1. Patients with Loeys-Dietz syndrome should have yearly magnetic resonance imaging from the cerebrovascular circulation to the pelvis. (Level of Evidence: B)"

Takayasu Arteritis and Giant Cell Arteritis (DO NOT EDIT)[4]

Class I
"1. The initial evaluation of Takayasu arteritis or giant cell arteritis should include thoracic aorta and branch vessel computed tomographic imaging or magnetic resonance imaging to investigate the possibility of aneurysm or occlusive disease in these vessels. (Level of Evidence: C)"



Surveillance of Thoracic Aortic Disease or Previously Repaired Patients (DO NOT EDIT)[4]

Class IIa
"1. Computed tomographic imaging or magnetic resonance imaging of the thoracic aorta is reasonable after a Type A or B aortic dissection or after prophylactic repair of the aortic root/ ascending aorta. (Level of Evidence: C)"
"2. Computed tomographic imaging or magnetic resonance imaging of the aorta is reasonable at 1, 3, 6, and 12 months postdissection and, if stable, annually thereafter so that any threatening enlargement can be detected in a timely fashion. (Level of Evidence: C)"
"3. When following patients with imaging, utilization of the same modality at the same institution is reasonable, so that similar images of matching anatomic segments can be compared side by side. (Level of Evidence: C)"
"4. Surveillance imaging similar to classic aortic dissection is reasonable in patients with intramural hematoma. (Level of Evidence: C)"
