  • Figure 1
    Abdominal plain radiograph and volumetric reconstruction
     

    AP abdominal plain radiograph. Low-grade obstructive ileus: marked dilation of colon and small bowel loops. Faecal content in sigma is detected.

     
    Area of Interest: Abdomen; Imaging Technique: Plain radiographic studies; Procedure: eLearning; Special Focus: Volvulus;

    Volumetric reconstruction in AP coronal projection. Colonic dilation with change of calibre in transverse colon (arrow).

     
    Area of Interest: Abdomen; Imaging Technique: Image manipulation / Reconstruction; Procedure: eLearning; Special Focus: Volvulus;
     
     
  • Figure 2
    Axial and coronal contrast-enhanced CT
     

    Contrast-enhanced CT in portal phase, axial projection. Colonic distention with collapsed descending colon (arrowhead).

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: eLearning; Special Focus: Volvulus;

    Contrast-enhanced CT in portal phase, coronal projection. Colonic dilation with collapsed descending colon (arrowheads). Sudden change of calibre in transverse colon (white arrow).

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: eLearning; Special Focus: Volvulus;
     
     
  • Figure 3
    Coronal and sagittal contrast-enhanced CT
     

    Contrast-enhanced CT in portal phase, coronal projection. ‘Whirlpool sign’. At the point of calibre change, twirling of transverse mesocolon vessels is seen (black arrowhead) shaping the classic ‘whirl’ image.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: eLearning; Special Focus: Volvulus;

    Contrast-enhanced CT in portal phase, sagittal projection. ‘Bird’s beak sign’: Transverse colon dilation with sudden sharpness and change of calibre.
