scanning

 [skan´ing]
1. close visual examination of a small area or of different isolated areas.
2. any of several diagnostic radiologic techniques, including computed tomography, magnetic resonance imaging, and positron emission tomography.
3. a manner of utterance characterized by somewhat regularly recurring pauses.
brain scanning see brain scanning.
MUGA scanning (multiple gated acquisition scanning) equilibrium radionuclide angiocardiography.
radioisotope scanning production of a two-dimensional record or image of the gamma rays emitted by a radioactive isotope concentrated in a specific organ or tissue of the body, as brain, kidney, or thyroid gland.
scintillation scanning the process resulting in a scintiscan.
thallium scanning production of a scintillation scan involving the use of thallium 201; see also thallium scan.
total body scanning use of computed tomography to examine a cross section of the entire body. The scanner produces an image of tissue density in a complete cross section of the part of the body being scanned. Total body scanning does not require the injection of a radiopaque substance, nor is there a need for use of a radioactive material to produce a record of the findings. The total body scanner is particularly useful in visualizing organs in the retroperitoneal space, for example, the pancreas, liver, spleen, and ovaries, and the abdominal section of the aorta.

scan·ning

(skan'ing),
The act of imaging by traversing with an active or passive sensing device, often identified by the technology or device employed.

scanning

/scan·ning/ (skan´ing)
1. the act of examining by passing over an area or organ with a sensing device.

MUGA scanning , multiple gated acquisition scanning equilibrium radionuclide angiocardiography.

scanning

Etymology: L, scandere, to climb
a technique for carefully studying an area, organ, or system of the body by recording and displaying an image of the area. A concentration of a radioactive substance that has an affinity for a specific tissue may be administered intravenously to enhance the image. The liver, brain, and thyroid can be examined, tumors can be located, and function can be evaluated by various scanning techniques. See also specific scanning techniques. scan, n., v.

scanning,

n a technique and protocol for carefully studying an area, organ, or system of the body by recording and displaying an image of the area using radioactive substances that have affinities for specific tissues.

scanning

close visual, electronic or radiographical examination of a small area or of different isolated areas of the body.

radioisotope scanning
production of a two-dimensional record of the gamma rays emitted by a radioactive isotope concentrated in a specific organ or tissue of the body, such as brain, kidney or thyroid gland.
total body scanning
utilization of computed tomography (CT) to examine a cross-section of the entire body. The CT scanner produces an image of tissue density in a complete cross-section of the part of the body being scanned.
For the most part total body scanning does not require the injection of a radiopaque substance, nor is there a need for use of a radioactive material to produce a record of the findings. However, contrast is used in some areas, particularly the skull, as it enhances the image.
The total body scanner is particularly useful in visualizing organs in the retroperitoneal space, for example, the pancreas, liver, spleen and ovaries, the abdominal section of the aorta, and in viewing the spine and skull.

Patient discussion about scanning

Q. Anybody to tell me more about MRI scan? had an MRIscan and this has snown adenocarcinoma of endometrium early stage There is no lymphatic involvement but is it possible an MRIscan to miss some tumor?

A. MRI is a very effective machine but it has it's limits. it has a great resolution but will not see very small tumors. therefore- it can miss metastasis sometime. but if your adenocarcinoma is in early stage- it might not sent metastasis. they did a biopsy? that can give you some idea what to expect.

Q. I am 15 weeks pregnant. I had my NT scan and blood draw today. Iam using my Hubby user name here.I am 15 weeks pregnant. I had my NT scan and blood draw today. I doubt whether I am in a risky state because I read in medical journal that women with certain amount of risk go for second trimester screening and not healthy pregnant women. Is it so? Please clarify?

A. There's something called an integrated sequential screening. You have the NT scan and blood draw in your first trimester, and then go back for an additional blood draw in your second trimester. They then calculate a unified result and present the results in the second trimester. Several other sources mentioned that often a high risk based on the NT scan and the first blood draw will prompt a diagnostic test. Yes, women with low or acceptable risk go on for the second trimester screening.

Q. I'm worried if she has ADHD. Is there any MRI or brain scan test to diagnoses the problem? My daughter Elba is 15. She regularly goes to school but often forgets to do daily activities. I'm worried if she has ADHD. Is there any MRI or brain scan test to diagnoses the problem?

A. Although in general practice MRI is not carried out to diagnose ADHD, the studies have shown that the ADHD brain has considerably less activity than does a normal brain when MRI's are compared. Stimulant drugs increases the chemical activity level, which decreases the symptoms. I shall suggest you to consult a physician specialized in this area.
