Can renal color Doppler ultrasound visualize the renal arteries?

Renal color Doppler ultrasound may not always visualize the renal arteries. This imaging modality primarily assesses kidney size and position, detects renal parenchymal tumors or space-occupying lesions, and identifies renal hypertrophy. Color Doppler ultrasound is merely one diagnostic tool among many. Accurate diagnosis of certain renal diseases requires additional evaluations—including renal function tests, urinalysis, and other relevant ancillary examinations—to precisely determine the patient’s specific condition. We recommend seeking medical evaluation at a hospital as soon as possible.
