ARDMS (American Registry for Diagnostic Medical Sonography) Practice Test

What can a sonographer identify during a renal ultrasound?

1. Only the size of the kidneys

2. Kidney stones, cysts, or tumors

3. The presence of blood flow to the kidneys

4. Cysts only if they are large

The correct answer is: Kidney stones, cysts, or tumors

A renal ultrasound is a vital imaging technique that allows sonographers to assess various structures and conditions related to the kidneys. The correct choice indicates that a sonographer can identify kidney stones, cysts, or tumors. During the ultrasound, sonographers utilize high-frequency sound waves, which can create images of the kidneys and surrounding structures. This imaging technique is particularly effective for visualizing solid masses like tumors, as well as fluid-filled structures like cysts, and can also clearly reveal calcifications or stones within the kidneys. Detecting these elements can provide critical information regarding the patient's renal health. While other options suggest limited capabilities, sonographers are trained to observe various aspects beyond just the size or presence of blood flow. Moreover, the detection of cysts is not restricted to large ones; even small cysts can often be identified with ultrasound technology. Thus, the comprehensive assessment provided by renal ultrasound facilitates the identification of multiple potential issues affecting the kidneys, making the correct answer accurate in reflecting the breadth of what can be recognized during this ultrasound procedure.
