Testicular torsion is a surgical emergency that occurs when the spermatic cord becomes twisted, cutting off blood supply to the affected testicle. To diagnose this condition quickly and accurately, testicular Doppler ultrasound is the preferred imaging modality. This technique allows for the evaluation of blood flow to the testicle, which is crucial because diminished or absent blood flow is indicative of torsion.

A Doppler ultrasound can not only confirm the diagnosis but also provides real-time imaging, allowing healthcare providers to assess the extent of blood flow to the testicle. In cases of torsion, you would typically observe reduced or no venous and arterial flow to the affected area. This capability makes Doppler ultrasound superior to other imaging techniques for this particular condition.

Using a CT scan or MRI would not be appropriate or efficient for diagnosing testicular torsion. These modalities are more complex, take longer to perform, and involve more radiation exposure or cost without providing additional relevant information for this acute situation. X-rays, on the other hand, are not useful in assessing testicular conditions and would not demonstrate the necessary vascular information to confirm or rule out testicular torsion. Thus, the utility of testicular Doppler ultrasound in providing accurate and timely assessment of blood flow makes it the
