Questions from Module 3 of the Prinicples component

QuestionAnswer
What does sonographers SSALT stand for? Size, Shape, Acoustic characteristics, Location, and Transonicity.
What are some guidelines for the measuring size of a structure? Measure largest perpendicular diameters (may not correspond to standard body planes), averaging may be used, HxLxW measurements require at least 2 images, measure along beam axis if possible, may measure next to structure
What are some guidelines and descriptors for Shape? Use multiple images if necessary, describe the overall shape (sausage-like, oval, elongated, serpentine, circular, irregular, etc) and the borders (hyperechoic, smooth, thick, thin, indeterminate, etc.)
What are some descriptors that describe acoustic characteristics? Echogenicity (hyperechoic, high/med/low echogenicity, anechoic), Texture (smooth, rough, cobblestone), and architecture (homogeneous, heterogeneous.)
How is transonicity determined and what does it tell? Look at the echogenicity of the tissues beneath the structure. Shadowing means the structure has high attenuation, vice-versa for enhancement
How is location show or described? shown by taking a sonogram that includes normal structures along with the target; described in general area
