Ch 9 New + Emerging Imaging Technologies in U/S Flashcards
What does ABUS stand for?
Automated breast u/s
What is automated breast u/s?
A method of using a calibrated u/s sweep to screen breasts for masses
List 4 advantages for using ABUS?
-Fast
-No radiation exposure
-Calibrated images (measuring)
-Images + screens dense breasts, whereas traditional mammography does not perform this as well
List 4 disadvantages for using ABUS?
-Time + cost
-Operator dependency
-Still requires a stand alone u/s unit
-Can not replace screening mammography
What does POCUS stand for?
Point of care u/s
Who typically uses POCUS?
Physicians
What is POCUS?
-Ultrasound that can be used at bedside + fits in a pocket
-Is becoming very popular
Can POCUS connect to our phone?
It may connect
How big are the POCUS devices?
Some are smaller traditional u/s units:
-Can be handheld, like a phone
-May be laptop based
When is POCUS used?
In angio suites + IV therapy
List 5 advantages of POCUS?
-Quick
-Cheaper
-Allows for bedside clinical diagnosis
-Needle guidance for IVs
-FAST u/s (done in emergency department)
List 4 disadvantages of POCUS?
-Images often are not stored on PACS
-Gap in medical record
-Not a full bedside exam
-Often requires full u/s exam anyways
(can cause legal issues by having a gap in the medical record + not having images saved)
Are the disadvantages of POCUS starting to out weight the advantages these days?
Yes
List 2 benefits to using wireless u/s probes?
-Portable
-Improves ergonomics in some situations
List 3 disadvantages to using wireless u/s probes?
-Heavy
-Needs to be charged
-Can get lost
Do standard u/s machines send images to PACS without being plugged into ethernet? If so, list advantages + disadvantages of this?
Yes!
Advantages:
-good for portables
-one less cord to manage
Disadvantage:
-security needs to be considered
What does artificial intelligence (AI) use algorithms for?
To “read” images + detect abnormalities
Artificial intelligence (AI) is used primarily with which imaging modalities?
MRI + CT images
AI is built in as a part of what system?
PACS
Can AI outperform humans?
Yes, at some tasks
What types of lesions can AI be useful for?
Lung + breast lesions
What is the name of the AI used in u/s?
SonoCNS by GE Healthcare
What does SonoCNS by GE Healthcare allow for?
-Allows for a 3D volume capture of the fetal head + automatic plane detection
-It can perform standard measurements automatically
AI in u/s can perform standard measurements automatically for which structures?
-Bladder volume calculations
-Thyroid measurements
-Nodule measurements
List 4 ways how scan assistants work + can help our workflow?
-They automatically advance our settings from 1 image to the next
-They guide new techs through protocols
-They reduce errors or missing images
-They can make exam times faster
What is B-Flow imaging?
A type of u/s imaging that allows visualization of blood flow by selectively enhancing the signal from moving blood cells, while simultaneously suppressing tissue signal
Does B-Flow imaging show flow direction or amplitude?
No, it is not like CD
What is B-Flow useful for detecting?
Trickle flow
