  • Figure 1
    Doppler ultrasound of renal arteries
     

    Spectral Doppler US of the right renal artery revealed a small amplitude waveform with a prolonged systolic rise.

     
    Area of Interest: Arteries / Aorta; Kidney; Imaging Technique: Ultrasound-Colour Doppler; Ultrasound-Spectral Doppler; Procedure: Diagnostic procedure; Special Focus: Haemodynamics / Flow dynamics;

    Spectral Doppler US: Intra-renal arterial waveform from right kidneys shows a tardus-parvus configuration.

     
    Area of Interest: Arteries / Aorta; Kidney; Imaging Technique: Ultrasound-Colour Doppler; Ultrasound-Spectral Doppler; Procedure: Diagnostic procedure; Special Focus: Haemodynamics / Flow dynamics;

    Spectral Doppler US: Parvus-tardus waveform from the left renal artery.

     
    Area of Interest: Arteries / Aorta; Kidney; Imaging Technique: Ultrasound-Colour Doppler; Ultrasound-Spectral Doppler; Procedure: Diagnostic procedure; Special Focus: Haemodynamics / Flow dynamics;

    Spectral Doppler US: Extension of the parvus-tardus wave-form to the abdominal aorta, indicating a more proximal stenosis.

     
    Area of Interest: Abdomen; Arteries / Aorta; Imaging Technique: Ultrasound-Colour Doppler; Ultrasound-Spectral Doppler; Procedure: Diagnostic procedure; Special Focus: Haemodynamics / Flow dynamics;
     
     
  • Figure 2
    Thoracic CT Angiography
     

    Axial image shows an aortic coarctation distal to the origin of the left subclavian artery and enlarged internal mammary arteries and intercostals collateral vessels.

     
    Area of Interest: Arteries / Aorta; Mediastinum; Thorax; Imaging Technique: CT-Angiography; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Obstruction / Occlusion;

    Sagittal multiplanar reformatted image demonstrate an aortic narrowing of the proximal descending aorta, distal to the origin of the left subclavian artery.

     
    Area of Interest: Arteries / Aorta; Mediastinum; Thorax; Imaging Technique: CT-Angiography; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Obstruction / Occlusion;

    Coronal multiplanar reconstructed image demonstrates narrowing of the proximal descending aorta.

     
    Area of Interest: Arteries / Aorta; Mediastinum; Thorax; Imaging Technique: CT-Angiography; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Obstruction / Occlusion;

    Curved multiplanar reconstruction of the thoracic aorta showing the aortic coarctation in the proximal descending aorta.
