Which diagnostic tool uses magnetic fields and radio waves to visualize cancer?

Magnetic Resonance Imaging (MRI) is the diagnostic tool that utilizes magnetic fields and radio waves to create detailed images of organs and tissues within the body, making it particularly useful for visualizing soft tissue structures. In oncopathology, MRI is advantageous for assessing tumors because it provides high-contrast images of different types of tissues, which can help distinguish between benign and malignant growths, determine the extent of cancer, and evaluate the effectiveness of treatment.

The technology behind MRI involves aligning the protons in the body’s tissues using a strong magnetic field, then sending radiofrequency pulses to disturb this alignment. As the protons return to their original state, they emit signals that are captured to produce images. This method allows for a non-invasive and highly detailed view of internal structures, providing valuable information that aids in diagnosis and treatment planning in cancer patients.

Other imaging techniques, like CT scans, X-rays, and ultrasounds, have their specific uses but do not rely on the same principles as MRI. CT scans use X-rays to produce cross-sectional images, while X-rays visualize dense structures like bones. Ultrasound relies on sound waves to generate images of soft tissues. Each of these methods has merits but does not utilize magnetic fields and radio waves, making
