Magnetic Resonance
It is a diagnostic scan that can capture images of the body in a bloodless manner, without emitting ionizing radiation and in any area of space, based on the magnetic properties that atomic nuclei have. It has the capacity to better differentiate the different anatomic structures than any other radiology test. Gadolinium paramagnetic contrast can be added to further delineate the different structures of the body.

 

Computerized Axial Tomography
It is also known as CT or scanner, it is a diagnostic test that uses X-ray imaging, obtaining multiple images of the human body shaped in sections that later can be treated by getting a computer to produce images in any area of space and three-dimensional images. In alot case the use of intravenous contrasts is necessary, they wiil allow a better image resolution and the characterization of many lesions.

Radiography
X-rays are a form of high-energy electromagnetic radiation that can penetrate the human body and produce an image on a photographic plate. In this path the radiation is attenuated according to the varying density of crossing structures, a fact that will become apparent in the photographic plate in the form of various shades of gray.

Ultrasound
Diagnostic technique that ultrasound uses(sound wave whose frequency is above the limit detectable by the human ear) to form images. A small instrument called a transducer emits ultrasound. These high-frequency sound waves are transmitted into the body area under study and its echo is received. The transducer picks up the echoes of sound waves and a computer converts the echoes into an image that appears on the computer screen. Ultrasound does not use X-rays, making it an ideal method for obstetric studies.

Mammography
Mammography is a diagnostic scan that uses X-ray image. It allows us to characterize some of the injuries found in physical examination and detect lesions not evident on palpation. It is therefore the preferred method for early detection of breast cancer (screening).

Orthopantomogram
Method of imaging that uses X-rays it is performed in a specific apparatus orthopantomogram. It produces a panoramic radiograph that includes the jaw molars and teeth, being of paramount value in the dentomaxilomandibular area.

Bone Densitometry
Bone densitometry is a test to determine bone density in order to diagnose osteoporosis. It can be done with X-rays, ultrasound or radioactive isotopes.
