What is contrast-enhanced ultrasound used for?
Abdominal contrast-enhanced ultrasound (CEUS) uses gas-filled microbubbles to better visualize organs and blood vessels within the abdomen and pelvis. This exam may evaluate the liver, spleen, kidneys, pancreas, bowel, and/or bladder.
How do I get CE credits for radiology?
You can earn credits by completing educational activities that meet criteria established by the ARRT. Of the required 24 CE credits, all must be Category A or A+ credit. Earning an additional certification will no longer receive CE credit effective for CE bienniums beginning on or after January 1, 2018.
How does contrast ultrasound work?
Partway through the ultrasound, this contrast is injected into your bladder with a catheter or your blood vessels through an IV line. This allows the technologist to take images both with and without contrast. Once injected, these tiny bubbles travel to your organs and make the organs much more visible on ultrasound.
What is contrast imaging in ultrasound?
Contrast-enhanced ultrasound (CEUS) is the application of ultrasound contrast medium to traditional medical sonography. Ultrasound contrast agents rely on the different ways in which sound waves are reflected from interfaces between substances. This may be the surface of a small air bubble or a more complex structure.
What causes contrast in an ultrasound image?
Contrast agents This phenomenon arises because the impedance for ultrasound in gas is markedly different from that for soft tissue. Impedance is the product of density and propagation speed, and it can be appreciated that impedance in air is low whereas that in soft tissue is high.
What is microbubble ultrasound?
Microbubbles are intravenous contrast agents used in contrast-enhanced ultrasound. Microbubble contrast agent is different to the agitated saline contrast agent often used in echocardiographic studies. Microbubbles consist of a gas surrounded by a lipid, lipopolymer, or polymer shell. They range from 2-10 µm.
How many CE is Arrt?
24 credits
WHAT ARE ARRT’S CONTINUING EDUCATION REQUIREMENTS? As an R.T., you’ll need to complete and report 24 credits of approved continuing education activities every two years (or 50 credits if you’re an R.R.A.).
What is CE probation with the Arrt?
A CE probation period lasts for six months. During that time, you’ll be able to complete and/or report your missing credits. You’ll record your activity on our online CE probation form and submit it along with a $50 fee. Once we confirm your activities, we’ll remove your CE probation status.
How do you flush out contrast dye?
If you received an injection of contrast dye, you should drink six to eight glasses of water to help flush it out of your system. Your study will be read by an imaging physician who specializes in the interpretation of CT scans. The results will be sent to your physician, usually within 48 hours.
What is range ambiguity in ultrasound?
Range-ambiguity artifacts (RAAs) are an erroneous mapping of returning echoes into a composite picture. This phenomenon is actually a combination of two phenomena: a ring-down artifact and RAA. This form is referred to as “complex RAA (searchlight phenomenon)” in this review.
What is the purpose of microbubbles?
Microbubbles are used to carry a drug or gene until a specific area of interest is reached, and then ultrasound is used to burst the microbubbles, causing site-specific delivery of the bioactive materials.
