C)ultrasonography.
D)angiography.

Question

Quizplus · Accepted Answer

Ultrasonography, also known as an ultrasound, is a procedure that uses sound waves to create images of internal structures in the body. It has been used to identify hydrocephalus in utero by measuring the expansion of the ventricles in the brain. Electroencephalography (A) measures electrical activity in the brain and is used to diagnose conditions such as epilepsy. Ventriculography (B) is a medical imaging technique that involves injecting a contrast agent into the ventricles of the brain and taking X-rays. Angiography (D) is a medical imaging technique that involves injecting a contrast agent into the blood vessels and taking X-rays to visualize blood flow.
