Correct option is D
Correct Answer:(d) MRI scan
- MRI (Magnetic Resonance Imaging): This technique uses a strong magnetic field and radio waves to generate detailed images of the internal structures of the body, especially soft tissues like the brain, muscles, and joints.
- It does not involve any ionizing radiation, making it safe for frequent use.
Other Option Information:
PET scan: PET (Positron Emission Tomography) scanning uses radioactive tracers to monitor metabolic processes within the body.It is useful for detecting cancer, brain disorders, and assessing the function of organs like the heart.
Ultrasound scan: This method uses high-frequency sound waves to create images of the inside of the body.It’s commonly used for monitoring pregnancies, as well as examining organs like the liver, kidneys, and heart.
CT scan: A CT (Computed Tomography) scan uses X-rays to take cross-sectional images of the body.It is effective in diagnosing internal injuries, tumors, and diseases affecting bones and organs but involves exposure to ionizing radiation.
Key Points:
- MRI uses magnetic fields and radio waves for imaging, making it highly detailed and safe as it avoids ionizing radiation.
- PET scan detects metabolic activity, Ultrasound uses sound waves, and CT scan involves X-rays.
