Can MRI detect the extent of the lesion?

Generally, MRI can identify the extent of lesions. If needed, consultation with a physician is recommended. Detailed analysis is as follows:

MRI uses a powerful magnetic field and radiofrequency pulses to cause hydrogen nuclei within the body's tissues to produce resonance signals, thereby generating detailed images. It allows comprehensive scanning of the body from multiple dimensions, such as axial, sagittal, and coronal planes. This multi-angle imaging approach enables physicians to clearly observe the shape, size, and boundaries of lesions from different orientations, thus accurately determining the extent of the病变.

MRI also offers high soft-tissue resolution, clearly depicting anatomical structures and characteristics of lesions throughout various regions of the body. It can display not only axial, sagittal, coronal, and various oblique sectional images, but also directly visualize subtle internal structures such as small blood vessels and nerve fibers. Physicians can accurately determine the location, size, and morphology of lesions based on abnormal signals observed on MRI images, providing crucial information for developing treatment plans.

Prior to the examination, patients should provide their medical and allergy histories in detail to ensure the safety and effectiveness of the procedure.
