Patient
male, 76 year(s)
 
 
  • Figure 1
    Skull to mid-thigh PET MIP Image

    Linear hypermetabolic activity in the right CFV and femoral vein (arrow). Excreted activity in the right lower quadrant ileal conduit, external bag, and tubing (arrowhead).

     
    Area of Interest: Extremities; Vascular; Veins / Vena cava; Imaging Technique: PET; Procedure: Diagnostic procedure; Special Focus: Embolism / Thrombosis;
     
     
  • Figure 2
    Axial low-dose CT image acquired in conjunction with PET

    Dilated right CFV (arrow) compared to normal caliber left CFV (arrowhead).

     
    Area of Interest: Extremities; Vascular; Veins / Vena cava; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Embolism / Thrombosis;
     
     
  • Figure 3
    Longitudinal colour Doppler image of right CFV

    Colour flow sonography demonstrates partially occlusive DVT.

     
    Area of Interest: Extremities; Vascular; Veins / Vena cava; Imaging Technique: Ultrasound-Colour Doppler; Procedure: Diagnostic procedure; Special Focus: Embolism / Thrombosis;
     
     
  • Figure 4
    Transverse grayscale image of right CFV, with and without compression

    No flattening of the right CFV was seen without (left) and with (right) compression.

     
    Area of Interest: Extremities; Vascular; Veins / Vena cava; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Embolism / Thrombosis;
     
     
  • Figure 5
    Axial enhanced CT pelvis (delayed phase)

    CT with contrast obtained one week after treatment was initiated reveals persistent thrombus in the right CFV (arrow).
