Non-invasive imaging

Definition

Non-invasive imaging refers to medical imaging techniques that do not require any surgical procedures or the introduction of instruments into the body. This approach allows for the visualization of internal structures and functions without causing harm or discomfort to the patient. It plays a crucial role in diagnostics, particularly in identifying conditions like cancer, where it can detect tumors or abnormalities while preserving patient integrity.

5 Must Know Facts For Your Next Test
