What are the different types of medical diagnostic imaging?
Medical diagnostic imaging concerns technologies that create images of the body's inside for diagnosis of health condition or disease. When doctors evaluate the symptoms and symptoms of the patient to identify the patient's condition or illness, the process and conclusion are called medical diagnosis. Because symptoms and symptoms do not always present themselves on the outer body, doctors use medical diagnostic imaging to control abnormalities inside the body. Different types of medical diagnostic imaging include X -ray, ultrasound, computer tomography (CT) scanning, magnetic resonance imaging (MRI) and nuclear medicine scanning. The patient's experience will depend on what type of technology is used, but most imaging procedures are fast and causes a minimum patient discomfort.
X -ray, also called Roentgren Waves or Radiography, is an example of fast and paintingCested Ledical Diagnostic Imaging. X -rays use electromagnetic radiation to create a picture of the inside of the body, in which denser objects such as bone are highlighted, and less dense objects such as fat appear in shades of gray. This technology can be used to determine whether the patient has broken or pinched bones, spine injuries, bones or joint diseases, heart or lung disease, pierced lungs or scoliosis, abnormal curvature of the spine. The X -ray can also be used to locate randomly swallowed objects, evaluate the cause of chest pain, detect blockage in blood vessels, control sinus infections and dental problems. X -rays produce a small amount of radiation, produce small discomfort and are safe for use in children.
CT Scan, also called Cat Scan, is a high -performance type of X -ray technology looking for internal bleeding, broken bones, blood clots, tumors, musculoskeletal disease, arterial Blocation and heart disease. During this examination, the patient is laid on the table and passes through a hole similar to the donut in the X -ray machine. The patient may also be administered with a contrasting material that will help create a clearer picture. Although this test is painless, it may require the patient to remain inside the machine for several minutes, causing discomfort for those with claustrophobia or chronic pain. Patients should tell their doctor if they can be pregnant.
Ultrasound, also called sonogram, uses sound waves to create a picture of the body tissue. They are often used to explore the fetal progress in the womb, heart, blood vessels, kidneys, liver and other internal organs. In this type of medical diagnostic imaging, the doctor applies a warm gel to the outer body overlapping the area that will be examined. The doctor then moves a device called a converter that produces high -frequency sound waves over the body. Sound waves reflect the tissues and the converter collects the return ofof the reins of the organs. Ultrasound is safe, painless and does not create any radiation, but is not effective in the imaging areas of the body that contains gas or are placed under the bone.
MRI are a type of medical diagnostic imaging used to look at the spinal cord, brain, heart, blood vessels and other internal organs. The patient lies as much as possible in the MRI machine, while the machine uses magnetic and radio waves to create a three -dimensional image of the inside of the body. Most patients will not experience any discomfort if they have no problems in an enclosed space or remain calm. The test usually has no harmful effects, but patients should inform their doctor whether they can be pregnant, have some electronic devices such as pacemaker, inside, or any pieces of metal in their body.
Nuclear scanning, also called radioisotope scanning or radionuclide scanning, use a radioactive substance and a gamma ray camera to create an Inside body. Radioactive substance is served in VelA small, harmless dose of orally or intravenously, through an injection and is left to travel through the body. When the substance reaches part of the body that must be explored, the patient lies in the machine for twenty to thirty minutes. Two -dimensional images taken by the machine shows whether the tissue works properly or not.
