CT Scanning
Also known as a "CAT" scan, the CT scan is a Computerized Axial Tomography scan that allows doctors to analyze organs and bones for diseases.

What does a ct scan with contrast show?
A CT scan, computed tomography, is a medical test performed to diagnose a malady. The CT scan will allow the doctor to see internal injuries not shown on an X-ray picture.
What does azimuth mean in ct scanning?
The angle of the tube and detectors in relationships the patient positioned during scout acquisition.
Where is Hi-Q spiral ct scan and specialty clinic in quezon city?
Malakas Street, Diliman, Quezon CIty. It is At the back of Philippine Heart Center
Is heart scan same as the CT scan?
Yes.
Newer name for the same thing:
- CT is 'computed tomography'
- CAT was 'computed axial tomography'
Both use a narrow x-ray beam rotated about the axis of the object being scanned (thus the word "axial" in the original name), a powerful computer is then used to reduce the information collected to produce a special photo called a "tomograph". No difference at all other than the name was shortened.
Who may lawfully read a ct scan?
A physician prescribes the study for a patient, a radiologist authorizes and protocols the study, an x-ray technologist executes the study. The physical "use" of the machine is done by the x-ray technologist, but each of these persons can be said to use ct scans. By the way ct scans are also used by veterinarians, and have been used for archaeological pursuits (the study of Egyptian mummy's.
Magnetic resonance imaging (MRI), nuclear magnetic resonance imaging (NMRI), or magnetic resonance tomography (MRT) is amedical imaging technique used in radiology to visualize internal structures of the body in detail. MRI makes use of the property of nuclear magnetic resonance(NMR) to image nuclei of atoms inside the body. MRI can create more detailed images of the human body than are possible with X-rays.
Do you have to stay home after you get a CAT scan?
You do not have to stay home after a CAT scan. The procedure has no residual effects. After you leave the clinic or hospital, you can resume normal activities if you are otherwise healthy.
A major discovery surfaced in 1987 by two curious people; Darrell Laurence and Adrian Shrine. Mr. Lawrence was head of Laurence Electronics and was friends with the genius, Mr. Shrine of Scotland. With their combined expertise, they managed to put together the largest search for the Loch Ness Monster in the loch of Inverness, Scotland known as Operation Deepscan. It was an expedition to sweep all areas of the loch, every depth of 745 feet in search for Nessie. Twenty boats that contained sonar units were sailed around the loch. The result... three very large moving objects. Were they real? We may never know.

An imaging scan that measures the activity or functional level of the brain by measuring its use of glucose.
Positron emission tomography, a process that uses radiation to give you a 3d image of the body.
PET scans are used to view nodules in the lungs or pleural cavity and check other organs for infiltrates or spots, such as a spot on a kidney which can't be seen on regular x-ray equipment. It defines and makes problems clearer to see.
How long do you have to fast before a ct scan of the abdomen?
- Depends on whether you sre haven contrast or not, but if you have contrast then yes and if you do not need contrast then no.
- A CT Scan needs contrast dye. Contrast dye is given to show up certain organs and also protect the kidneys. The dye can either be given in liquid form mixed with a tiny bit of fruit juice or pop (instructions will be given to you by your pharmacist if you are having liquid contrast dye) or the contrast dye may be given by IV at the imaging department. Depending on what time you are having your CT Scan you do need to fast. Example: If your CT Scan is in the morning then you can have breakfast, but nothing but LOTS of water during the whole day and another 2 litres of water before you go for your test. You may have other liquids only during fasting such as tea; fruit juice, but be sure you drink plenty of water! If you have future questions phoning any pharmacist will help you put your mind at rest.
What is the full form of CT scan?
CT is computed tomography and CAT scan is computed axial tomography.
How can someone scan documents?
The first thing you need of course is a scanner. There are many different types of scanners available. One of the easiest to use would be ones that you can lay the document on the glass and scan it that way.
Is there an age limit for patients undergoing cat scans?
Anyone can get a cat scan young or old. It is not recommended for women who are pregnant, since it uses radiation which could be harmful to the fetus.
Can an MRI scan miss what a CT scan would show?
A CT scan is a computer-assembled set of X-rays taken from different vantage points. The computer can create 3D models of whatever it images, but the nature of X-ray imaging is that it is more effective for denser tissues (bone), than soft-tissues (organs or blood). There are new CT techniques that can help image organs (the heart is of particular interest), but MRI is generally capable of imaging soft tissues with greater detail. MRI is more frequently used for neurological imaging, and can be used to do chemical analysis of tissues (spectroscopy) inside your body non-invasively.
Because they use very different means to image, both CT and MRI can 'miss' things that would better show up on the other modality.
CAT scan used to be short for Computerized Axial Tomography. Think of this as using computers to map the body in the axial plane. (axial is a direction that the image is processed in).
The newer machines not only do axial but also multiple other imaging planes (coronal,sagital,biplane,multi plane,etc.) So now they dropped the "axial" and just call it CT scan short for Computerized Tomography.
