title: [Contrast-enhanced ultrasonography in the diagnosis of acute experimental incomplete testicular torsion].
abstract: OBJECTIVE
  To explore the application value of contrast-enhanced ultrasonography (CEUS) in the diagnosis of acute experimental incomplete testicular torsion.
  
  
  METHODS
  Seven incomplete and 1 complete testicular torsion models were established in 8 healthy hybrid dogs by twisting unilateral spermatic cord. The twisted testes were included in the model group and the healthy ones in the control. All the dogs underwent CEUS before, immediately after, and/or 6 hours after the torsion, followed by time-intensity curve analysis.
  
  
  RESULTS
  The arriving time (AT) and the time to peak (TTP) of the contrast agents in the bilateral testes were almost coincident, and the peak intensity (PI) and the area under the curve (AUC) in the bilateral testes basically the same before the torsion. The incompletely torsion testes showed delayed perfusion of contrast agents, prolonged AT and 'TP, and decreased PI and AUC as compared with the contralateral testes (P < 0.05), while the completely torsion one exhibited no perfusion all the time.
  
  
  CONCLUSIONS
  CEUS has a very high application value in the diagnosis of acute incomplete testicular torsion.
