I made this glossary to have a better knowledge on words related to my field of study.
- Anechoic structure
- Noun and adjective
- Body chamber without echoes; fluid-filled structures that appear black on the sonogram.
- Example: The first sign of pregnancy on an ultrasound is the appearance of a rounded anechoic structure.
- fr: Structure anéchogène
- Attenuation
- Noun
- The tendency for ultrasound waves to decrease as they travel through tissues.
- Example: The intensity and amplitude of the sound wave decreases, and this process is known as attenuation.
- fr: atténuation
- Biopsy
- Noun
- The removal and examination of tissue, cells, or fluids from the living body.
- Example: A biopsy allows scientists to look at a sample of your cells under a microscope and carry out tests on the tissue.
- fr: Biopsie
- Color flow Doppler
- Noun and adjective
- Doppler scan that measures blood flow by attributing color to different velocities of movement.
- Example: During the exam, a color flow Doppler was necessary for the blood circulation.
- fr: Doppler couleur.
- Coronal scanning plane
- Noun and adjective
- The ultrasound beam enters the body from the lateral (right or left) direction.
- Example: The doctor will be doing a coronal scanning plane of her heart.
- fr: Une coupe coronale.
- Couplant gel
- noun
- Gel used in an ultrasound scan; functions as the medium through which sound energy is transmitted between the transducer and the patient's skin.
- Example: The doctor used couplant gel for the ultrasound exam.
- Cyst
- noun
- A membranous sac or cavity of abnormal character in the body, containing fluid.
- Example: The doctor found a cyst in my liver.
- fr: Un kyste
- Distal position
- Noun and adjective
- Away from the point of origin or trunk
- Example: Blood pressure cuffs are placed on the proximal and distal thigh, below the knee and above the ankle.
- fr: Position distale.
- Echocardiogram
- noun
- Ultrasound of the heart and cardiac blood vessels; used to measure blood flow through the heart and how well it functions.
- Example: Yesterday, the doctor told me that I had to pass an echocardiogram.
- fr: Échocardiogramme
- Gallstones
- Noun
- They are hard, pebble-like pieces of material, usually made of cholesterol or bilirubin, that form in your gallbladder.
- Example: Cholesterol is the primary ingredient in most gallstones.
- fr: Un calcul biliaire.
- Hyperechoic
- Adjective
- Structures that return greater echoes of sound waves and appear bright white on a sonogram.
- Example: A hyperechoic liver lesion is a region on that liver that shows up on an ultrasound.
- fr: Hyperéchogène
- Hypoechoic
- Structures that return weaker echoes of sound waves and appear gray or black on a sonogram.
- Example: A hypoechoic mass looks dark gray on an ultrasound.
- fr: Hypoéchogène
- M-mode
- Noun and adjective
- Early ultrasound modality that shows the time-motion display of the ultrasound wave; displayed as a single scan line, not a visual image.
- Example: He had to pass a M-Mode for his heart.
- fr: Mode-M
- Obstetric ultrasound
- noun and adjective
- Scan of the lower abdomen to detect and monitor a growing fetus during pregnancy; typically occurs during 12-week scans (fetal size and development) and 20-week scans (fetal organs and development).
- Example: I had to pass an obstetric ultrasound to see my baby for the first time.
- fr: Échographie obstétricale
- Sagittal scanning plane
- Noun and adjective
- the ultrasound beam enters the body from anterior or posterior (front or back) position
- Example: They will have to do a sagittal scanning plane to be able to see her liver.
- fr: Une coupe sagittale
- Speckle noise
- Noun
- Noise interference that reduces the quality of the image resolution in a sonogram.
- Example: Speckle noise is generally serious, causing difficulties for image interpretation.
- fr: Du bruit
- Time gain compensation
- A technique in which signal gain increases as time passes.
- Example: A way to overcome ultrasound attenuation is time gain compensation.
- fr: Temps de compensation
- Transducers
- Noun
- Devices that produce sound waves in ultrasounds and send return echoes to a computer, which compiles them into a sonogram
- Example: Transducers have different types of frequencies depending on what part of the body we want to see.
- Transverse scanning plane
- Noun and adjective
- The ultrasound beam enters the body from anterior, posterior or lateral (front, back, right, or left) position; scans in a diagonal or transverse angle.
- fr: Une coupe transverse.
- Ultrasound
- Noun
- The diagnostic or therapeutic use of ultrasound and especially a noninvasive technique involving the formation of a two-dimensional image used for the examination and measurement of internal body structures and the detection of bodily abnormalities
- Example: They used ultrasound to examine his heart.
- fr: ultrason
