CT Scanning

Not really no, you can only determine it from patient history, first person observation or EEG changes during a seizure.

Low attenuation can mean different things. Was it a CT scan or MRI, do you know if they used contrast. An area with low attenuation needs to be re-evaluated to see what it is. Why did he have the scan? Did he have a trauma/injury? Was he having headaches or other symptoms? What else did the doctors tell you?

A prominent prostate on Ct can be a sign of Benign Prostatic Hypertrophy (BPH) or enlarged prostate. Some symptoms include: increased frequency, nocturia, hesitancy, dribbling, weak stream, stop and go, can't completely empty. Bph can be diagnose with a digital rectal exam. It is highly recommended that any man over the age of 50 get a rectal exam.

As CT can identify structures that have physical density differences less than 1%. On the other hand X ray films can identify structures having density difference of about 10%.

If all you had was barium, then the kidneys have nothing to do with it. Barium is for visualizing the GI tract (stomach/small bowel/large bowel.)

I do not think CAT stands for anything, I just think it stands for a normal kitten.

For my nephew it was hydrocephalus (water on the brain). He was a premie and they said it was probably caused from an injury when he was so small and the head is so sensitive. He had to have a drain tube put in that shunts the fluid from his brain to his stomach. They have to watch that and it will have to be replaced as he grows. Otherwise he is a very bright, normal 3rd grader and all is well. You can find a lot of information by running a search on the word. (Warning, there is another type of hydrocephalus that is much more serious than his, but I believe it is a birth defect that has much different symptoms) Hope this helps

if you know this you r awesome cause i dont

hypodensity often means that there is edema, or swelling in that area of the brain. Therefore, this could indicate that there was an ischemic stroke that occurred within the parietal area of the brain. Hope this helps.

This is a new idea in some areas so it is best to talk to your doctor as to what they recommend. Basicaly.. there is a small chance that the metformin (and other diabetic medications) could crystalize in the kidneys causing damage. The policy where I work recommends not taking the medication for 48 hours after you get the dye injection. We dont have a hold for the medication before getting the dye.

If you are diabetic, ask your doctor if the medication you take has any restrictions when getting any kind of dye for a test. You may also ask the technologist doing your test, before the injection, what their policy is.

major advantage of spiral CT is higher resolution and the ability to reconstruct images anywhere along the length.Although spiral is more advantageous for many applications, conventional CT is still a superior and precise method for imaging many tissues.

to detect pulmonary embolisms, determine how much blood is flowing to lungs, determine which areas of the lungs are capable of ventilation, and assess how well the lungs are functioning

During the study, patients are asked to ingest an egg sandwich containing a radioactive substance (for example, technetium) that can be followed by a special camera. The emptying of the material from the stomach is then followed.

There are no generally contraindicated medications after a contrast enhanced Ct Scan.

Yeah, a cat scan is pretty much safe.

I say 'pretty much' because the ionizing rays cat scans apply can cause DNA which can lead to cancer. Same as X-rays. However, this is very rare, and your doctor would only give you a cat scan/X-ray if he thought you really needed one.

What I'm saying here is that, for all practical purposes, cat scans are safe.

The nursing responsibilities during a CT scan may vary from place to place. The nurses often insert an IV for contrast dye and ensure the patient is comfortable.

CT scans are now used in most Hospitals and is now available in almost every country

Certain modern CT scan techniques may show if you have a tendency or likelihood of Alzheimer's. Alzheimer's doesn't appear as a concrete thing but certain distance measurements from the brain ventricles to the mid line of the brain can be plotted by specialist doctors in a special table to determine the likelihood of Alzheimer's. The degree of atrophy of the brain can also indicate problems with senility.

what is a hypodense in a uterus

Yes. Staples make the CT scan image look different and make it harder to see small changes around that area, but they are perfectly OK to go in a CT scanner machine. Most imaging areas have certain rules about putting patients in an MRI machine with staples. If getting an MRI check with them on their policies.

IT MEANS Fcuk PASSPORT AT ORIGIN

Yes. Make-up has no effect on a CT scan.

It is advised that mascara (eye-lash makeup) is not worn for MRI scans because it often contains tiny threads of metal (lead or iron) - which is put in there to make the lashes look thicker. These tiny metal particles can heat up during an MRI and cause burns to your eyelids.

Clinically, correlation occurs after various diagnostic tests are run. Doctors take test results and compare them to factors such as a patient's age, sex, weight and medical history to make an accurate diagnosis based on the results.

A full body PET scan can take 30 to 45 minutes. A scan of a single lamp or a single organ can take as little as 10 minutes.
