Accurate diagnosis of aortic dissection requires understanding treatment options and timely imaging. While CT, MR, and echocardiography aid evaluation, aortography is key for surgical planning, with MR imaging poised for future primary use.

Area of Science:

  • Radiology
  • Cardiovascular Imaging
  • Vascular Surgery

Background:

  • Aortic dissection diagnosis requires prompt confirmation and characterization for effective treatment.
  • Accurate imaging is crucial for differentiating dissection from mimics and guiding therapy.

Purpose of the Study:

  • To outline the role of various imaging modalities in the assessment of aortic dissection.
  • To emphasize the importance of selecting appropriate imaging studies based on clinical context and treatment goals.

Main Methods:

  • Review of current noninvasive imaging techniques including computed tomography (CT), magnetic resonance (MR) imaging, and echocardiography.
  • Discussion of the established role of aortography in vascular anatomy definition, particularly for surgical planning.

Main Results:

  • CT, MR imaging, and echocardiography have significantly improved noninvasive aortic evaluation.
  • Aortography remains the gold standard for defining vascular anatomy when surgical intervention is contemplated.

Conclusions:

  • The choice and timing of imaging studies are critical for managing patients with suspected aortic dissection.
  • Advancements in MR angiography suggest it may become a primary modality for acute and chronic dissection evaluation.
