Insights

Multi-detector computed tomography (MDCT) effectively visualizes the Adamkiewicz artery (AA) in most patients with acute Stanford type A aortic dissection, aiding in understanding spinal cord blood supply.

Area of Science:

  • Radiology
  • Cardiovascular Imaging
  • Spinal Cord Anatomy

Background:

  • Acute Stanford type A aortic dissection poses risks to spinal cord perfusion.
  • The Adamkiewicz artery (AA) is crucial for anterior spinal artery supply.
  • Assessing AA involvement in dissections is vital for patient management.

Purpose of the Study:

  • To assess the detectability of the Adamkiewicz artery (AA) using multi-detector computed tomography (MDCT).
  • To evaluate the origin and lumen involvement of the AA in patients with acute Stanford type A aortic dissection.

Main Methods:

  • 51 patients with Stanford type A dissection underwent contrast-enhanced 64-row MDCT.
  • Source and multiplanar reformation images were used to analyze AA visualization and origin.
  • Detailed imaging parameters included collimation, rotation time, kV, and mAs.

Main Results:

  • The Adamkiewicz artery (AA) was visualized in 70% of patients.
  • The AA typically originated from the left side (83%) between T7 and L2 (97%).
  • AA origin was from the true lumen in 64% and the false lumen in 36% of cases.

Conclusions:

  • Multi-detector computed tomography (MDCT) demonstrates high detectability of the Adamkiewicz artery (AA).
  • MDCT is a valuable tool for visualizing the AA in acute Stanford type A aortic dissections.
  • Findings aid in understanding spinal cord perfusion in this patient population.

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Imaging Studies VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
