Ultrasound
Ultrasound is a medical imaging technique that uses high-frequency sound waves to produce real-time 2D and 3D views inside the body.
Magnetic Resonance Imaging (MRI, NMRI, MRT)
Magnetic resonance imaging (MRI) is a medical imaging technique that uses magnetic fields, radio waves, and field gradients to produce images of the body's internal structures. This imaging technique is also called nuclear magnetic resonance imaging (NMRI) and magnetic resonance tomography (MRT).
Computed Tomography (CT, X-Ray CT, CAT)
Computed tomography (CT) is a medical imaging technique that produces cross-sectional images and 3D volume renderings of the body's internal structures using X-rays. This technique is also called X-ray computed tomography (X-ray CT) and computerized axial tomography (CAT).
Fluoroscopy (X-Ray)
Fluoroscopy is a medical imaging technique that produces a real-time view of the body's internal structures using X-rays.
Projectional Radiography (X-Ray)
Projectional radiography is the practice of imaging the body's internal structures using X-rays or other forms of high-energy electromagnetic radiation.
