| 1 | Color Doppler ultrasound is the first choice for renal AVM screening but a definitive diagnosis still requires angiography. | |
| 2 | However, detailed imaging studies, including Doppler ultrasonography and magnetic resonance imaging, may provide early precise diagnosis. | |
| 3 | Such wobbling betrays itself as tiny Doppler shifts in the spectral lines present in a star's light. | |
| 4 | Preoperative color Doppler study facilitates identification of skin perforators, thus simplifies the procedure. | |
| 5 | Three lesions were all detected by color Doppler ultrasound and were proved by renal angiography. |
