Final answer:

The radiological procedure among the given options is angiography. Option d.

Step-by-step explanation:

The radiological procedure among the given options is angiography.

CT (computerized tomography) involves taking multiple X-ray images to create a cross-sectional view of the body (Figure 1.19a). MRI (magnetic resonance imaging) uses a magnetic field and radio waves to produce detailed images (Figure 1.19b). Ultrasound technology uses sound waves to create images of organs or monitor pregnancies (Figure 1.19d). Angiography involves injecting a contrast dye into blood vessels to visualize the flow of blood (Figure 1.19c).

In summary, the correct answer is D) angiography as it is a radiological procedure.

An MRI does not use radiation, but rather radio waves in combination with a magnetic field, and an ultrasound uses sound waves, which are not a form of radiation. As for which imaging study is safest during pregnancy, ultrasounds are considered the safest option since they do not use electromagnetic radiation and are the least invasive of imaging techniques.
