CT Scanning

Some CT exams are done w/contrast, some w/o contrast and some are done first w/o and then w/contrast. The body organs show up well w/o contrast. If the Dr. needs to see vasculature then IV contrast would be used. Contrast kind of "highlights" vessels. For instance, tumors need a great deal of blood to grow and if one is suspected a CT w/o may be done first and then a CT of the same area done W/ contrast to verify increased vasculature. The Kidneys and liver and heart all have allot of blood running thru them so these organs can yield more info when done w/ and then w/o contrast. There is also Oral contrast that a patient would drink to "highlight" the stomach and bowels for several different reasons/diagnoses.

The salary of a cat scan technologist will depend on the location and experience of each person. On average, the yearly salary is an estimated $63,096.

A non contrast brain CT scan can pick up bleeds in or around the brain. It can also detect skull fractures and calcifications within the brain. Certain tumours can also be seen without the use of contrast.

A bone scan, or x-ray is simply a different type of scan than an MRI. No kind of scan is better than another, it simply depends what the scan is trying to ascertain.

Some patients may experience a salty taste, flushing of the face, warmth or slight nausea, or hives from an intravenous contrast injection. Technologists and radiologists have equipment and training to help patients

CAT or CT scanning can be any of a number of different scan technologies, as CAT stands for Computed Axial Tomography and says nothing about the beams used. In common use, however, CT and CAT scans typically use X-rays, and those that use more exotic techniques are named by the technique they use (PET and NMR scans, for instance).

CT scans may not detect small problems within the bowel which might cause pain and bloating. Colonoscopies and barium enemas are both superior to CT scans for visualising small irregularities of the intestine. Certain diseases like irritable bowel syndrome which can be caused by stress or certain foods, may not show on any regular imaging test.

Scanned means like something that goes over things then tells you the results. To scan something is to make a quick detailed survey of it.

Probably not since cancer filled lymph nodes are painless. Your doctor is doing a CT scan probably to find an infection.

I got the similar thing. Went for the ct scan everything was fine...

There are minimal risks involved with getting a CT scan. Your doctor should check your kidney function to be sure your kidneys can handle getting dye. This may be done at your doctors office or at the place that does the CT. The newer dyes used now are lower risk of any allergic reaction and are much easier on your kidneys to process. We check everyone over 16 years old before giving any dye.

As always discuss with your doctor if there is any reason not to get the dye.

No, autism isn't detectable on CT scans.

A type of X-ray where they use a computer to create a three-dimensional picture of the body part. CAT stands for Computerized Axial Tomography.

Tomography is complicated to explain but basically it was discovered if you move the x-ray plate and the x-ray tube at the same time while making a radiographic exposure depending on where you put the fulcrum you can create and x-ray that looks at a specific level inside the body.

You can decide you need to see the level of the patient 1 cm, 2 cm 3 cm or so on and the x-ray will be an image that displays only the most detail that many centimeters deep into the patient's body. This was predominantly done for x-raying the kidneys or tumors. So you would measure the patient's body thickness then determine by measurements assigned to the fulcrum, by the x-ray machine manufacturer, where to set the fulcrum in order to make a tomogram thick enough to display the area you want to see.

So the x-ray machine while exposing would be moving from head to toe above the patient while the x-ray plate moved in sync with it so that the x-ray beams are hitting the plate the entire time it travels. So if the x-ray tube was at the head of the patient at the start of the exposure the rod attached from it to the plate would put the plate at the opposite end near the patient's feet. As the x-ray tube moved toward the patient's feet the plate under the patient would move toward the patient's head.

This type of tomogram is a coronal cut from the front of the body to the back.

The CAT scan was developed with different approach in that the x-ray tube would travel around the body of the patient like a hula hoop as it goes around the body and shoots x-rays through the patient from left to right in a circle. The x-rays are not shot onto a plate with film as regular tomograms but was instead sent to a computer sensor that does a better job of taking the data given to it by the x-ray beam and assigning a pixel value from black to white of the areas inside that circle.

This image takes a picture of all the internal structures of the patient with much greater detail than previous topograms. So the images of the patient look like you have made slices like a loaf of bread. So the images are referred to as slices. Viewing the body this way is known as an axial view. So the fact that it is a type of tomogram and the fact that it was put together by the computer, and adding the fact that it is an axial cut gives you CAT Computed Axial Tomography.

Interesting enough most facilities call them CT scans now taking out the A for axial. Even though the images are shot axial just as I described, the software on computers allows the scanner to stack the slices then by doing vast amounts of mathematical equations on the data it collected it can reconstruct images that are Coronal (slices that look like the start from the front of the patient to the back), as well as Sagittal (cuts from right to left of the body)

I think that was on a tv series like Scrubs or House.

computer assisted tomography (CT)

Please ask your doctor. It may not take 4 years of med school to learn to interpret shadows, but it does take at least 3 years of residency to do it.

A computed tomography scan (CT scan) will show inflammation and fluid within the airspaces of the mastoid, as well as the erosion of the little walls of bone that should separate the air spaces.

If two scans early in pregnancy say the same they are extremely accurate. Your pregnancy gestation was 14 weeks and 1 day as pregnancy is counted from the first day of your last period (if you have a 28 day cycle) it was 12 weeks from conception.

Yes, CT scans show internal bleeding very clearly.

This term means that the T3 vertebra of the thoracic spine has a visual deformity seen on x-ray. The endplate is the part of the bone that touches the disc, so a compression deformity means that the bone has been compressed at this connection.
