About Medical imaging

Medical imaging
Medical imaging is also known as Diagnostic imaging, they utilise ionising radiations, except MRI and ultrasound. Sometimes even radioactive substances are used to produce visual images of the internal structures and any abnormalities like cancer related, heart related, etc. there are varied types of techniques being utilised to detect the disease. For example: Tomographic techniques, ultrasound, MRI, Fluoroscopy, Immunoassay, Ultrasonography, Mammography, Radiography, Molecular imaging etc. MRI utilises high energy magnetic field to diagnose a particular abnormality whereas, Ultrasound uses high energy sound waves for the detection of the disease. Molecular imaging provides a complete picture of internal body at molecular and cellular levels with the aid of radioactive substances.
