CT Scanning

if you're allergic to iodine, you'll probably have an allergic reaction

I was told it is like gout,but instead of uric acid it has pyrophosphates. It can be anywhere in the body. I had a ct scan and it is in my arm and chest.

Yes.

The main purpose of a DEXA scan is to measure bone marrow density. It can be used to look at the spine and all extremities, including arms, hands, fingers, legs, feet and toes.

We usually ask you not eat 4 to 8 hours prior to getting a CT scan of anything in the abdominal or pelvic area. (the time difference depends on protocol of your doctor and the place doing the CT scan) There are exceptions and depends on what the doctor wants to see. You may always call the place doing your CT and talk to the CT technologist. (the person who answers the phone may not know)

780.79 is malaise/fatigue. LAN is lymphadenopathy. The CT is being done because you are complaining of fatigue, and your health care provider wants to make sure you don't have lymph node disease.

CT Scans are of importance because they provide us with a better picture of thicker tissue inside the human body. With them we're able to look at organs such as the brain, which is CT scanned very often. I myself have had seven CT scans of my brain taken and they showed my doctors that I had cerebral edema, swelling in my brain. They can also show hemhorages and other cranial injuries.

A stands for Amplitude, and B stands for Brightness. B-scan technique basically combines a series of A-scans, taken from a range of different angles to form a 2d image. Whereas, A-scan only gives a graph-image of reflected intensities in a c.r.o. screen.

The probe for B-scan contains smaller crystal in various orientation unlike single large crystal in A-scan technique.

A CT scan --- also called computerized tomography or just CT --- is an X-ray technique that produces images of your body that visualize internal structures in cross section rather than the overlapping images typically produced by conventional X-ray exams.

The puncture site depends on the part of the pancreas to be sampled, ranging from it's head to it's tail. Draw a ring around the body from the level of the underside of the ribs to the level of the umbilicus and you have a rough idea of where the puncture will be. The path of the needle is chosen to avoid vascular and digestive structures.

It shoould be the other way round. Urografin is not licensed for oral use and should not be used as an oral contrast agent. Omnipaque is licenced for oral used and should be used as an oral contrast agent. Check the manufacturer's product data sheets to confirm.

Since I have been doimg them, I usually see movement within an hour to been taken. Hope this helps

It's were the delivery company picked the package up at, basically it means they got it and it's on it's way.

Yes and/or no.

This depends on what the test is looking for and the policies of the place doing your CT and your doctor. Always talk to your doctor about alternatives and what is best for your case.

For some CT tests, the oral prep (drink) is of minimal concern. For some CT tests it can be the main concern.

Well, the good thing is that the doctors found nothing seriously wrong. You may want to explore other causes of the numbness. It could be an allergic reaction to medicine, certain foods or even household factors such as dust or mold. If doctors have already told you that nothing is wrong (that *they* can find) consider looking into herbal medicine or treatments such as accupressure or accupuncture. ~ T

Radiolucent indicates a structure which lets relatively more x-rays through than the adjoining structures. The radiolucent structure is black on film, and the radio-opaque structure is white. Everything is relative. From radiolucent to radio-opaque, in a progressive order are air, fat, water (soft tissues), bone, metal.

The difference is in the type of radiation used to form the image. A Computed Axial Tomography (CAT) scan can use any type of radiation to create the image, the specific type is not specified in the name, but most often uses X-rays; but a Positron Emission Tomography (PET) scan specifically uses positrons as the radiation form. A third type, Magnetic Resonance Imaging (MRI) uses the miniscule magnetic fields of naturally occurring compounds within the human body to create its images.

One chest CT is around 10 millisieverts of radiation. A traditional chest X-ray is only 0.02 millisieverts. Therefore a CT scan has 5,000 times the radiation dose of a chest x-ray.

A typical patient who visits the emergency room receives a cumulative radiation dose of 40 millisieverts over a five-year period. Ten percent of patients end up with 100 or more millisieverts. Both levels are well above the safety threshold for lifetime radiation exposure. Exposures above the threshold leave patients vulnerable to increased long-term risk of cancer.

Some reports suggest about one third of all CT scans may be unnecessary. Overuse of these tests may be a significant factor in raising the total public risk of cancer. Some researchers note that while the risks of cancer from CT scans remain low, the increased incidence of cancer may be considerable. To balance image quality with these safety concerns, radiologists use a protocol known as the ALARA principle, short for As Low As Reasonably Achievable. It's meant to keep CT dose factors low to minimize risk while maintaining maximum diagnostic benefit.

Patients are advised to ask their doctors if another diagnostic exam could be used instead of a CT scan. Ultrasound and MRI, for example, do not emit the same sort of harmful radiation. Manufacturers have added adjustable dosage settings on the CT scanning equipment that take into account a patient's size and weight. Patients should inquire if technicians operating the machines are trained to minimize radiation exposure while still providing accurate images.

C-T, or computed tomography, is a series of x-rays done in 3 dimensional 'slices' of the study area of the body, which allows for very specific detail of the imaged area. A C-T may be either non-contrast, contrast, or both. No matter what part of the body is being imaged, the liquid contrast material is injected intravenously. A nurse or specially trained technician will start an IV, usually in the arm, and inject the contrast material, and then the C-T scan is performed. If both non-contrast and contrast studies are being performed, the non-contrast study is done first.

Generally speaking you should not suffer any pain or side effects from having a CT scan. However in some cases you may feel a slight dull ache, if the symptoms persist after 7 days consult your GP.

Yes because it was named after Dr. John Lang Down.

what is my answer?

I got a full body bone scan and it costed around 4,000, give or take.

An x-ray of the breast is called a mammogram.

HRCT stands for High-Resolution Computed Tomography. This is performed on a technically advanced CT (Computerised x-ray) machine and gives the doctor excellent details of normal and diseased tissue. For the lungs it almost always involves using intravenous injection of x-ray contrast medium as well, to identify normal and abnormal blood vessels.
