Consider the following statements with reference to the Magnetic Reson...
For those trying to look inside the human body without surgery, magnetic resonance imaging is an indispensable tool.
- It is used to obtain images of soft tissues within the body. Soft tissue is any tissue that hasn’t become harder through calcification.
- It is a non-invasive diagnostic procedure widely used to image the brain, the cardiovascular system, the spinal cord and joints, various muscles, the liver, arteries, etc.
- Its use is particularly important in the observation and treatment of certain cancers, including prostate and rectal cancer, and to track neurological conditions including Alzheimer’s, dementia, epilepsy, and stroke.
- The MRI technique’s use of strong magnetic fields, individuals with embedded metallic objects (like shrapnel) and metallic implants, including pacemakers, may not be able to undergo MRI scans.
- Working:
- In MRI procedure reveals an image of a body part using the hydrogen atoms in that part.
- It uses the body's natural magnetic properties to produce detailed images from any part of the body. For imaging purposes the hydrogen nucleus (a single proton) is used because of its abundance in water and fat.
- The machine includes a superconducting magnet creating a stable magnetic field, aligning hydrogen atom spins. A radiofrequency pulse is emitted, exciting excess atoms.
- When the pulse stops, these atoms emit energy, detected and converted into signals by a receiver. These signals are processed by a computer to generate detailed 2D or 3D images of the scanned body part.
Hence both statements are correct.

Consider the following statements with reference to the Magnetic Reson...
Explanation:
1. Use of Body's Natural Magnetic Properties:
- Magnetic Resonance Imaging (MRI) utilizes the body's natural magnetic properties to create detailed images of internal organs and tissues.
- The procedure involves placing the patient inside a large magnet and using radio waves to generate signals that are processed by a computer to form 2D or 3D images.
2. Non-Invasive Diagnostic Procedure:
- MRI is a non-invasive diagnostic tool commonly used in the medical field.
- Unlike other imaging techniques such as X-rays or CT scans, MRI does not involve exposure to ionizing radiation, making it a safer option for patients.
Therefore, both statements are correct. MRI harnesses the body's magnetic properties to produce images and is a non-invasive diagnostic procedure widely utilized in medical practice.
