How do MRI scans detect tumors?

MRI scans detect tumors using magnetic fields and radio waves to create detailed images.

MRI scans use a strong magnetic field and radio waves to create detailed images of the body's internal structures. Tumors have different magnetic properties than surrounding tissue, which allows them to be detected by the MRI machine.

The magnetic field causes the protons in the body's tissues to align with the field, and the radio waves cause the protons to emit signals that are detected by the machine. The signals are then processed by a computer to create detailed images of the body's internal structures, including any tumors that may be present.

MRI scans are particularly useful for detecting tumors in soft tissues, such as the brain, spinal cord, and muscles. They can also be used to detect tumors in other parts of the body, such as the liver, kidneys, and lungs.

In addition to detecting tumors, MRI scans can also be used to determine the size and location of the tumor, as well as whether it has spread to other parts of the body. This information is critical for developing an effective treatment plan for the patient.
