X-rays are a type of radiation called electromagnetic waves. X-ray imaging creatures pictures of the inside of your body. The images show the part of your body of different shades of black and white. This is because tissues absorbs different amounts of radiation.
An x-ray is preformed by a machine that sends individual x-ray particles phantons through the body. The phatons pass through the body and the resulting images are recorded on a computer or special film.
The images produced by an x-ray examines bones,teeth, lungs,breast, heart, blood vessels and digestive tracts by creating images structured containing air that appears black and muscle, fat and fluid appearing gray.
X-Rays are typically used to examine broken bones but can also be used to spot any forms disease or tumors growing in the body.
computed tomography (CT) of the body uses speacial x-ray equipment to help detect variety of diseases and conditions. CT scanning is fast painless,noninvasive and accurate. In emergncy cases,it can reveal internal injuries and bleeding quickly enough to help save lives.
A series of x-ray views taken from many diffrent angels are combied to produce cross sectional images of the inside of the body. These images help diagnose and help treat medical conditions on the part of the body in which it was found
CT scans are typically used to examine the chest, abdomen, pelvis, spine and other skeletal structures using ionizing radiation which can increase your risk of developing cancer
A CT scan is preformed inside a large tube that looks like a large doughnut standing on its side as a person lies on the table in the center. The X-ray tube rotates around the body. The table slowly moves through the inside of the machine. Each rotation yields several images of the inside of the body.
Magnetic resonance imaging (MRI) of the body uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of the inside of your body. It may be used to help diagnose or monitor treatments for a variety of conditions within the chest abdomen and pelvis. If you're pregnant, body MRI may be used to safely monitor your baby.
An MRI scan is performed inside a large magnet and the person lies in the center. The machine scans the body by turning small magnets on and off. Radio waves are sent into the body, the machine then receives returning radio waves and uses a computer to create pictures of the odd part being scanned
Unlike X-Rays and Ct scans which use radiation,an MRI produces a detailed image of soft tissue versus X-Rays and CT scans which create images of hard tissue, bones and teeth. It produces cross sectional images of the body.
MRI's are typically used to examine the brain,spine,joint,abdomen,blood vessels and pelvis. It is very safe as the magnetic field itself does not hurt people unless they have certain types of metal implanted in their body.
Bone Scan
A bone scan is a nuclear imaging test that helps diagnose and track several types of bone disease.Your doctor may order a bone scan if you have unexplained skeletal pain,bone infection or a standard x-ray. A bone scan also be an important tool for dectecting cancer that has spread(metastasized) to the bone rom the tumors
