CT Contrast

TermDefinition
Iopamidol ISOVUE. Low-osmolar (LOCM). NON-IONIC. Non-salts that DO NOT dissociate. Less adverse reactions
Ioversol OPTIRAY. Low-osmolar (LOCM). NON-IONIC. Non-salts that DO NOT dissociate. Less adverse reactions
Iohexol OMNIOPAQUE. Low-osmolar (LOCM). NON-IONIC. Non-salts that DO NOT dissociate. Less adverse reactions
Diatrizoate HYPAQUE. High-osmolar (HOCM). IONIC. Salts (sodium/meglumine) that DO dissociate into 2+ ions.
Iothalamate CONRAY. High-osmolar (HOCM). IONIC. Salts (sodium/meglumine) that DO dissociate into 2+ ions.
Iodixanol VISIPAQUE. Iso-osmolar. Same osmolality as blood. Neutral.
Fludeoxyglucose (FDG) F 18. Nuclear Medicine used for PET scans. Typical dose is 10-15 (mCi). Pt's blood glucose must be 150mg/dL or below & have fasted 6-12 hrs prior.
.1% Barium Sulfate VOLUMEN. Neutral enteral contrast. Low density.
Biphasic Injection Technique A higher rate is injected initially, followed by a lower rate. Helps widen the period of optimum peripheral arterial enhancement.
Saline Flush Helps broaden peak enhancement, allows less contrast to be used, & may lessen adverse affects of CM.
Corticomedullary (late arterial) Phase 30-40 sec after injection. Optimal enhancement of the renal cortex /veins. Shows max differentiation b/w renal cortex & renal medulla. Also pancreatic phase.
Nephrographic (parenchymal) Phase 70-90 sec after injection. Visualizes renal parenchyma. Renal cortex & medulla are same = good for parenchymal lesions. Portal opticacification & optimal liver enhancement = assessment of disease spread.
Excretory (delayed) Phase After 3-15 min. CM is excreted into renal calyces, opacifying renal pelvis, ureters, & bladder. Demonstrates filling defects & lesions involving the urothelium.
Arterial Phase 20-30 sec. Maximum opacification of the arterial enhancement.
Portal Venous phase 60-70 sec (45-50 sec) after injection. Optimal gastric/intestinal wall enhancement. & liver parenchymal enhancement.
Retrospective Gating Only data acquired during diastole are used for image reconstruction
Prospective Gating Data acquired in an axial "step and shoot" mode & only during the diastolic portion of the R-R interval
Shaded Surface Display (SSD)/Surface Rendering 3D model of a specific tissue type by limiting the displayed volumetric data, on the basis of an attenuation threshold. Adds color, lighting, & textures.
Volume Rendering 3D tech that utilizes the entire required data set but adjusts the opacity of voxels in the 3D image, according to the tissue characteristics
Iopromide ULTRAVIST. Low-osmolar (LOCM). NON-IONIC. Non-salts that DO NOT dissociate. Less adverse reactions

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
