Intravenous contrast is used in CT to help highlight blood vessels and to enhance the tissue structure of various organs such as the brain, spine, liver and kidneys. "Intravenous" means that the contrast is injected into a vein using a small needle. Typically the contrast is loaded into a power injector, which injects the CT contrast using tubing through the needle into the body during a specific period in the CT exam.

Lenox Hill radiology only uses the newest and safest "non ionic" contrast available on the market. This is shown to have a much lower incidence of allergic reaction than the older "ionic" contrast. The most common side effect of the contrast includes a warm or hot "flushed" sensation during the actual injection and a "metallic" taste in the mouth, which usually lasts less than a minute or so. There is no treatment necessary for this as it is only a passing sensation.

The contrast is injected into a vein using a small needle during a specific period in the CT exam. The contrast circulates the blood stream, through the heart and arteries, capillaries and veins, to essentially “enhance” the tissue structure of your organs so they appear highlighted on the CT images for a more precise diagnosis.

Oral contrast is used to image the stomach and intestines. It is a very dilute, flavored barium solution that you drink approximately 1 hour prior to an examination. Intravenous contrast is sometimes referred to as "dye". Although colorless, it contains iodine, which makes specific organs, blood vessels, and tissues visible on x-rays for better detection of disease or injury. It is not radioactive.

Contrast medium is used to increase tissue contrast between normal and abnormal structures hence allowing better differentiation and more precise diagnosis. The intravenously injected contrast medium becomes distributed all over the tissues of the body and consequently increases their density; therefore increases the ability of these tissues to absorb and attenuate the x-ray beam and the more the tissue takes contrast medium the more they appear bright in CT.

Absolutely. We use “non-ionic” contrast, which has a much lower incidence of allergic reaction than the older “ionic” contrast.

The most common side effect is a warm sensation during the injection and a "metallic" taste in the mouth. These are only passing sensations and usually last less than a minute or so. For some patients, itching or hives (bumps on the skin) may occur and can last from several minutes to several hours after the injection. This can be treated with medication at the time of the exam or after by the referring physician.

intravenous or IV is a catheter that is introduced into a vein for the purpose of administering fluid, anesthetic medications, and other medications.

Contrast ratio is the ratio of luminance between the brightest white and the darkest black of a particular device or a particular environment. Projected cinema film, or a photographic reflection print, has a contrast ratio of about 80:1. Television assumes a contrast ratio, in your living room, of about 30:1. Typical office viewing conditions restrict the contrast ratio of a CRT display to about 5:1.

IVIG is a treatment for many immune disorders. Preliminary research suggests that it may help maintain pregnancy in women who have experienced secondary recurrent miscarriage by improving the mother’s immune response to this pregnancy. Currently, Dr. Stephenson is conducting an international trial to test whether IVIG helps promote successful pregnancies in women who have suffered secondary recurrent miscarriage.

You can start diets and some supplements without a clinician, however, there is no one "protocol" for successfully treating autistic children, so educating yourself is key. Free lectures and tutorials from the latest Defeat Autism Now! (DAN!) Conferences are available online Many families have contacted ARI over the past 40 years describing successful initial interventions at home using a variety of strategies, including:

This substance is given to highlight various body parts and is eliminated in a day or two. It is usually given by mouth or injection. It is normal to feel a warm sensation as the dye makes its way through your body.

Contrast is the term used for the material that is injected intravenously into a vein in your arm or hand. It is used to enhance the visibility of certain tissues or blood vessels. Few adverse reactions are reported with MRI contrast.

This is not a dental procedure and we will call in an anaesthetist to administer a drug through a vein in the patient's hand. The patient then goes into a deep sleep while the dental procedure is carried out. The patient recovers in minutes after the drug is stopped.

Yes. A small IV will be started in one arm to allow quick treatment if seizures become longer, stronger or more frequent than usual. When not in use, it is capped off, and not attached to any lines or drips.

Acid reflux disease, also known as gastroesophageal reflux disease (GERD) is a fairly common affliction. It is characterized by bouts of intense heartburn or a burning sensation in the back of the throat. Zenith 42 Plasma HDTV sets, also known as plasma HDTV displays have been obtainable for several years; however, they are more popular than ever today. find articles | submit articles | link to us | site map | terms of use | privacy policy | contact us | advertising | partner with us

The oral contrast drink is for patients who are having for a stomach/bowel CT scan. The barium-based drink essentially “enhances” the gastrointestinal tract so it can be better defined on the CT images.

Allergies to shellfish or iodine need to be pre-medicated before you are injected with contrast media. Tell your doctor about your allergies. You will be asked again about any allergies before you have a test that involves taking contrast material and the technologist or nurse will make sure you are pre-medicated.
