  • Figure 1
    Ultrasound (Transverse Section - Dual)

    Split transverse images showing the parenchymal changes in both testes (R=right, L=left), with more hypoechoic and oedematous right parenchyma. Technique: High frequency sonography (linear array 10-14 MHz transducer)

     
    Area of Interest: Genital / Reproductive system male; Imaging Technique: Ultrasound; Ultrasound-Colour Doppler; Procedure: Diagnostic procedure; Equipment; Observer performance; Special Focus: Acute; Ischaemia / Infarction; Pathology;
     
     
  • Figure 2
    Doppler US (Longitudinal Section)
     

    Two sequential images of right testis (longitudinal sections) showing hypoechoic parenchyma (3 x 3 cm) and confirming avascularity (void of signal in the white square) with peri-testicular oedema. Technique: Colour...

  • Figure 3
    Twirling Sign Movie

    A dynamic ultrasound movie-clip showing the 'twirling sign'. Technique: Movie acquisition performed by scan-sweeping of the US probe on the right upper scrotum (cranio-caudal direction).
