A renal transplant is a surgically placed donor kidney, monitored closely with Doppler ultrasound for vascular and parenchymal complications.

The renal pelvis is the funnel-shaped collecting area at the center of the kidney, evaluated by ultrasound for dilation indicating obstruction.

The renal parenchyma is the functional tissue of the kidney, assessed on ultrasound for thickness, echogenicity, and disease.

A renal cyst is a fluid-filled sac in the kidney, one of the most common incidental findings on abdominal ultrasound.

Renal cell carcinoma is the most common kidney cancer in adults, often detected incidentally as a solid mass on ultrasound.

The renal artery supplies blood to the kidney and is evaluated by Doppler ultrasound for stenosis and flow abnormalities.

A refractive artifact occurs when the ultrasound beam bends at a tissue boundary, causing structures to appear duplicated or displaced.

The radial artery is a major artery of the forearm, palpable at the wrist, and evaluated by ultrasound for patency and suitability for vascular access.

The quadriceps tendon connects the quadriceps muscles to the kneecap and is evaluated by ultrasound for tears and tendinopathy.

Pyloric stenosis is a thickening of the pylorus muscle in infants that causes projectile vomiting, diagnosed by ultrasound.
