Magnetic Resonance Imaging (MRI) offers detailed images of soft tissues, aiding in the accurate diagnosis and staging of tumours. It plays a crucial role in determining the most effective treatment approach by providing comprehensive insights into tumour characteristics. 

Computed Tomography (CT) scans generate detailed cross-sectional images of the body's internal structures. This imaging technology is vital for detecting abnormalities, monitoring treatment responses, and guiding surgical interventions. 

Specialized X-ray imaging of the breast, mammography is essential for the early detection of breast cancer. It helps identify changes in breast tissue before physical symptoms develop, enhancing the chances of successful treatment. 

Ultrasound uses high-frequency sound waves to capture live images of the body's internal organs. It is instrumental in examining tumours, assessing their size and location, and guiding biopsy procedures.

A primary imaging tool, X-rays are used to diagnose various conditions by providing images of bones and certain tissues. They remain a standard in assessing structural changes and detecting masses.
