Final answer:
MRI and Ultrasound are two non-invasive procedures that provide images of internal structures using radio waves, a magnetic field, and sound waves.
Step-by-step explanation:
Two non-invasive procedures that provide images of internal structures are MRI (Magnetic Resonance Imaging) and Ultrasound. MRI uses radio waves and a strong magnetic field to create detailed images of tissues and organs within the body. Ultrasound uses sound waves to create images of organs and structures in real-time.
