Transcript text: 19. "Angiograms" are used for:
recording the electrical activity of the heart muscles
recording metabolic activity in the brain
recording pictures of blood vessels
recording pictures of bones
Solution
The answer is the third one: recording pictures of blood vessels.
Explanation for each option:
Recording the electrical activity of the heart muscles: This is incorrect. The procedure used for recording the electrical activity of the heart is called an electrocardiogram (ECG or EKG).
Recording metabolic activity in the brain: This is incorrect. Metabolic activity in the brain is typically recorded using techniques like positron emission tomography (PET) scans.
Recording pictures of blood vessels: This is correct. Angiograms are imaging tests that use X-rays to take pictures of the blood vessels. They are often used to identify blockages or other abnormalities in the blood vessels.
Recording pictures of bones: This is incorrect. X-rays or other imaging techniques like CT scans are typically used to take pictures of bones.
In summary, angiograms are specifically used for recording pictures of blood vessels.
