CAMRT Radiography Practice Exam

Is an intravenous pyelogram (IVP) safe for pregnant patients?

1. Yes, it can be performed safely

2. No, ultrasound is preferable

3. Yes, if using low radiation

4. No, only under strict medical supervision

The correct answer is: No, ultrasound is preferable

An intravenous pyelogram (IVP) involves the use of ionizing radiation and contrast material to evaluate the kidneys, ureters, and bladder. In the context of pregnant patients, the potential risks associated with radiation exposure to the developing fetus raise significant concerns. During pregnancy, there is a heightened awareness of the potential impacts of radiation, particularly in the first trimester when organogenesis occurs. Ultrasound is considered safer for pregnant patients because it does not use ionizing radiation. Instead, it utilizes sound waves to create images of internal structures, which minimizes any risk to the fetus. Consequently, in situations where an examination of the urinary system is necessary for a pregnant patient, ultrasound would typically be the preferred imaging modality. Therefore, while an IVP might be performed safely under certain conditions in non-pregnant patients, the inherent risks associated with radiation exposure make ultrasound a more suitable and safer alternative for assessing urinary anatomy and function in pregnant patients.
