Imaging of Aneurysms and Dissections 53 good candidates for MRI and may require sedation. Patients with pacemakers, automatic implantable defibrillators, and many metallic implants are also not MRI candidates. Finally, MRI is not suitable for restless or hemodynamically unstable patients because data for MRI are acquired over relatively long time periods, and physical communication with the patient is hindered during the examination. Although there are no conclusive data that patients with acute aortic syndromes who undergo MRI have increased morbidity or mortality rates, the longer examination time of MRI compared with competing technologies (e.g., CT or TEE) has to be factored into the decision, regarding the diagnostic evaluation of such patients. MRI offers extremely high (submillimeter) in-plane resolution and has inherently high contrast resolution. Accordingly, adjacent tissues can be imaged as having a big difference in signal intensity, depending on their magnetic properties and the technical characteristics of the imaging sequence. Although the physics underlying various image acquisition techniques is beyond the scope of this review, the selection of the optimal diagnostic protocol and image interpretation requires a good knowledge of the advantages and limitations of each approach. With black-blood MRI techniques, the normally flowing blood appears black. These techniques are typically used to assess anatomy and also have value for tissue characterization. The components of the atherosclerotic plaque can be separated based on their appearance in T1-, T2-, and proton-density weighted images, and on differential enhancement following administration of paramagnetic contrast media (such as gadolinium chelates). With black blood images, precise measurements of the aortic lumen diameter and wall thickness can be readily obtained (Fig. 9). Thus, black blood images are clinically used to assess aortic aneurysm size and to evaluate whether there is mural thrombus lining the vessel wall. In patients with aortic dissection, the intimal flap can be readily identified, thus establishing the diagnosis. Because of the relative ease of identification, even in early studies, conventional black blood techniques were shown to have very high sensitivity for acute aortic dissection (9). However, image quality can be adversely affected by several factors. Motion artifacts may occur from excessive respiratory and whole body bulk displacement. Blood pool signal suppression may be incomplete, making vessel border definition difficult, particularly in areas of decreased blood flow (for example inside an aneurysm or at the false lumen of an aortic dissection). The differential blood signal suppression inside the true and false lumens may be helpful to identify the pathology (Figs. 10 and 11). With white blood MRI techniques, the normally flowing blood appears white. As image acquisition is rapid (20–30 ms), these techniques are typically obtained for acquisition of cine images with a high temporal resolution. Early sequences for white-blood imaging (fast gradient-echo sequences) relied on the inflow of blood to the slice of interest. Newer image acquisition schemes (steady-state free-precession sequences) rely more on the difference of magnetic properties between the blood and surrounding tissues (a combination of T1 and T2 weighing), allowing for excellent border definition even with slower flow rates. Besides obtaining anatomic measurements, bright blood images can also be used
54 Danias Figure 9 Transverse black blood MR image at the bifurcation of the pulmonary artery (PA) in a patient with aneurysm of the ascending aorta (AAo), with a 60 mm vessel diameter. There is excellent contrast between the vessel wall and blood pool in the AAo, PA and descending thoracic aorta (DAo). Figure 10 Black blood oblique sagittal image including the entire thoracic aorta (A) and similar view from the 3-dimensional maximal intensity projection reconstruction from the gadolinium (Gd)-enhanced aortic MRA (B), in a patient with aortic aneurysm following surgical replacement of the ascending aorta (AAo) with a gortex graft. The descending thoracic aorta (DAo) is aneurysmal. In the black blood image (A) signal suppression is good in the AAo because of rapid blood flow, while in the DAo blood signal suppression is not adequate due to slower flow. This may not be appreciated with the Gd-enhanced aortic MRA (B).
