What is CEUS imaging?
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. This procedure requires little to no special preparation.
What is B mode sonography?
B-Mode is a two-dimensional ultrasound image display composed of bright dots representing the ultrasound echoes. The brightness of each dot is determined by the amplitude of the returned echo signal.
What is the purpose of placing a pillow under the patient in ultrasound?
If the ultrasound table does not incline, placing a pillow behind the patient’s upper chest will improve comfort. Typically ultrasound tables have a retractable section beneath the legs with stirrups, which allow for the performance of a transvaginal ultrasound examination if needed (Figure 3.2).
What is CEUS used for?
Contrast-enhanced voiding urosonography is a special type of CEUS exam for which the diluted microbubbles are given intravesically via a urinary catheter. It is mainly used for the evaluation of vesicoureteral reflux in paediatric patients.
What are microbubbles in ultrasound?
Microbubbles are used for contrast ultrasound imaging as blood-pool agents in cardiology and radiology. Their promise as targeted agents for molecular imaging is now being recognized. Microbubbles can be functionalized with ligand molecules that bind to molecular markers of disease.
What is M-mode and B mode?
B-mode: In B-mode ultrasound, a linear array of transducers simultaneously scans a plane through the body that can be viewed as a two-dimensional image on screen. M-mode: M stands for motion.
How many types of ultrasound scans are there?
(These images are called sonograms.) But did you know there are other kinds of ultrasounds too? According to the American Pregnancy Association, there are seven different types.
How many ultrasounds should a sonographer do in a day?
On an average day, the majority of sonographers perform 9–11 examinations [1] that can last anywhere between 20–45 minutes [2]. This results in spending an average of 5–7 hours per day actively performing ultrasound examinations [2].
