Question

Which type of scan does not provide a clear image of anatomy, but is used to obtain information of how a tissue or organ is functioning?

1) CT scan
2) MRI scan
3) PET scan
4) Ultrasound scan

Answer 1

A PET scan is used to obtain functional information about an organ or tissue, such as metabolic activity, rather than clear anatomical images.

Step-by-step explanation:

The type of scan that does not provide a clear image of anatomy, but is used to obtain information about how a tissue or organ is functioning, is a PET scan (positron emission tomography scan). This medical imaging technique uses radiopharmaceuticals to produce images of active blood flow and the physiological activity of the target organ or organs. PET scans are particularly useful in detecting the metabolic activity of cancer cells, thereby providing critical information about the presence and spread of cancer. In contrast, CT (Computed Tomography), MRI (Magnetic Resonance Imaging), and ultrasound scans are primarily used to produce clear images of the anatomy of the body.
