CT angiography is a highly accurate diagnostic tool for suspected aortic dissection, offering superior visualization of intimal flaps and dissection extent compared to other imaging methods.

Area of Science:

  • Cardiovascular Imaging
  • Diagnostic Radiology

Background:

  • Immediate diagnosis of thoracic aortic dissection is critical for timely intervention.
  • Conventional imaging modalities have limitations in fully assessing aortic dissection.

Observation:

  • Three patients with suspected aortic dissection underwent color-flow Doppler echocardiography and CT angiography.
  • Spiral CT angiography provided multiplanar reconstructions for detailed aortic assessment.

Findings:

  • CT angiography accurately identified ascending (Stanford type A) and descending (Stanford type B) aortic dissections.
  • The technique effectively visualized intimal flaps, dissection extent, aortic size, and pericardial fluid.

Implications:

  • CT angiography is a preferred diagnostic modality for suspected aortic dissection.
