The most commonly employed contrast media for intravenous cholangiography is Iodipamide meglumine.
What type of contrast agent is room air? Negative.
Barium sulfate suspensions are nearly totally safe if they remain within the GI tract. Their toxicity increases dramatically if spillage occurs into the Peritoneum or Circulatory system.
In infants with swallowing disorders and adults with suspected bronchoesophageal fistulas, it is often prudent to select what type of contrast agent? Oil based iodine contrast media.
Iopanoic acid, sodium tyropanoate, and sodium ipodate are among the most common agents used for Oral cholecystography.
Most common contrast media for arthrography? Ionic water based iodine contrast media
Most common contrast media for sialography? Oil based iodine contrast media
Most common contrast media for esophagraphy? Barium sulfate contrast media
Most common contrast media for cholangiography? Ionic water based iodine contrast media
Most common contrast media for urography? Ionic water based iodine contrast media
Most common contrast media for mammography? No contrast media
Most common contrast media for hysterosalpingography? Ionic water based iodine contrast media
Most common contrast media for cholecystography? Ionic water based iodine contrast media
Most common contrast media for venography? Ionic water based iodine contrast media
The principle advantage of a low osmolality non-ionic contrast agent is its decreased Toxicity.
A patient is to be scheduled for a BE, IVU, and a GI Series. The sequence for these exams is IVP, BE, GI.
As the concentration of an iodine contrast media is increased, an increase in ______ should be anticipated. Viscosity, Toxicity and Opacity.
There are two general classifications for getting materials into the blood stream Enteral administrations (the absorption of medications through the mucus membranes) Parenteral administrations are those that involve the placement of the agent into the tissues or into the blood stream (injections).
A patient is to be scheduled for a GI series, gallbladder, and an L-spine. What is the proper sequence? L-spine, gallbladder, GI Series.
Because of the possibility of residual contrast media, which of the following studies is normally performed last in a sequence of exams? Esophogram, BE, IVP, Gallbladder series? Esophogram.
The esophogram is performed last in a series because it may take up to? 2 days for the barium to be completely eliminated from the GI tract.
A 4 year old is brought down to the radiology department for an intravenous urogram. The radiologist orders 40% of the normal 50 cc adult dosage be used. The amount to be prepared is? 20 cc (multiply the adult dose by 40%)
A barium enema is to be performed on a patient suspected of having a perforated bowel. The contrast media preferred for this procedure would be a Water based iodine preparation.
A low osmolality contrast agent is able to deliver a relatively _______ concentration of iodine with _________ particles in solution than conventional ionic contrast agents. High, Fewer.
During radiographic exams requiring long intravenous infusions, a _________ is often performed over typical intravenous needles. Butterfly set.
Most of the new low osmolality contrast agents which are classified as multipurpose can be employed for angiography, urography, arthrography, and myelography
A commonly employed category of drugs that are used to promote defecation in patients are termed Cathartics.
The principle reason that iopamidol and iohexol are now beginning to replace meglumine salts as the primary agents for intravenous urography is their lower toxicity.
In order to prevent possibly damage to the rectum, the enema tip should never be inserted more than 4 inches.
What are two major compounds used in the formulation of a low osmolality (non-ionic) contrast agents? Iohexol and Iopamidol
A serious complication following the administration of an iodine contrast agent is development of a moving blood clot that obstructs the blood supply to the lung. This is called a Pulmonary embolus.
The contrast agent that does NOT dissociate into charged particles when placed in a solution is designated as a Non-ionic contrast agent.
The principle difference between ionic and non-ionic contrast media is related to the ability to form charged particles or ions. Non-ionics are chemically less reactive and therefore cause fewer harmful effects.
