MRI is a non-invasive technique that provides detailed images of tissues by utilizing strong magnetic fields and radio waves. It is especially useful in histology for visualizing soft tissues and detecting abnormalities. MRI can differentiate between various tissue types based on their water content and other properties, making it a powerful tool for pre-histological diagnosis. The high-resolution imaging capability of MRI allows for the assessment of tissue architecture, which is crucial in planning biopsies and other histological procedures.
