How to interpret a CT SCAN?
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.
What is the Difference between ct scan and mri?
MRI is Magnetic Resonance Imaging and a CAT is a computerized X Ray (Computer Assisted Tomography) MRI will work fine in case of diagnosis of soft tissues and CT will work fine for bony structures and inner ear analysis. Also MRI do not use any radiation it is based on magnetic effect so less side effects compared to CT which uses X- rays. MRI is very much costlier compared to CT. MRI is problematic in case if the patient is having some metallic implant, which will cause interference with the magnetic field. In order to determine any hairline crack then MRI would be preferred compared to CT.
Can a pregnant woman have a CT scan safely?
It won't harm the pregnant woman. It WILL, however, hurt your unborn fetus. Depending how far along you are in your pregnancy and which body part is imaged will determine how much it will possibly interfere with your fetus' development. For example, if you were to get a CT scan of your brain, then your abdomen area would be shielded and your baby would be pretty well protected from any errant radiation as it is not in the primary radiation beam. If you were to get a CT scan of your abdomen, however, this would more than likely only happen in an extreme emergency situation as the dose to your unborn fetus would be great and it would surely disrupt his development. To what degree, no one really knows. It would also depend on how many weeks pregnant you are. The farther along that you are, the better the outcome in lessening your chance of significant damage to your unborn child. Radiation DOES kill cells. While we can regrow cells, sometimes (in development) those cells cannot be replaced if they were being formed at a critical time in the babies development. Any radiation study being requested on a pregnant female should always be questioned as to the importance of the study and can any other test be done first. You and your doctor must outweigh the risks and benefits before undergoing a radiation test while pregnant.
Chances of getting cancer from 3 CT scans?
Radiation exposure from a CT scan is similar to, though higher than, that of a conventional x ray.Although severe contrast reactions are rare, they are a risk of many CT procedures. There is also a small risk of renal failure in high-risk patients
What does a three phase CT scan diagnose?
A three phase CT scan is a ct scan, usually of the liver, that requires an injection of contrast medium, this injection helps outline the vessels of your body by giving the x-rays something to be absorbed by besides blood which has a very low absorption rate. The phases are: 1. Scan during injection: arterial phase, this will highlight lesions in or around the artery leading into the liver. 2. Scan during injection or shortly after: portal vein phase, this will show lesions in or around the portal vein. 3. Delayed scan after injection: this will allow the soft tissue to absorb the contrast and may highlight changes in tissue.
What is the use of CT METER?
is 3 phase Meter electicity to for the measurement of elektricity 3 phase.

Which type of scan use in pregnancy test 3-dimentional or ct scan?
NEVER a CT scan. In fact, if you are pregnant do everything you can to prevent exposure to xrays. 3-dimentional isn't a machine. Some ultrasound machines are capable of giving a 3-dimentional image and ultrasounds are used to check on the progress of the futus during pregnancy, it is not used in a pregnancy test. A pregnancy test is taked with blood or urine.
What is cardiac ct scan?
Cardiac computed tomography, cardiac CT is an x-ray to look for heart problems. The cardiac CT takes a 3-d picture of the whole heart.
How do you calculate multiplying factor in 3 phase kwh meter using ct ratio is 600VA 5 class 5.0?
The question is incomplete, because there are no mention about CT & PT ratios. 600VA 5 can not be CT ratio.
How do you calculate multiplying factor in 3 phase 4 wire energy meter?
mf is ratio of CT ration of meter box to CT ration written on meter. ex: CT meter box: 30/5, Meter ct ration 1/1. MF : (30/5)/(1/1)= 6

What happen when the polarity of current transformer is reversed in three phase kilowatt hour meter?
The measured Power in KWh will become one-third beacause the output of one CT which is reveresed will cancel the output of other CT and therefore the final output will be from only one CT (i.e 1/3 of total output)
How do you calculate multiplying factor in 3 phase kwh meter using c.t. ratio is 2505VA 5 class 5.0?
multiplying factor = Line CT Ratio / Meter CT Ratio Usually it is mentioned on Meter that MF = 1 if CT Ratio is 200/5 or MF = 2 if CT Ratio is 400/5. There can be an additional multiplication factor that would be mentioned on the meter.
How do you ground one of the phases from three phase three wire in order to make single phase?
you can't do this. to get single phase from 3 phase you must disconnect 2 of the phases and use one of them as a neutral...b.
