When compression is applied to ducts, what may occur?

• A. May be better visualized.
• B. There may be no change.
• C. Debris may disperse.
• D. Image artifacts increase.

Answer: (A)

Compressing the ducts helps them stand out more clearly on the image. By thinning the tissue between structures and reducing overlapping silhouettes, the duct lumens and walls align more with the imaging plane and contrast between the duct interior and surrounding tissue improves. This makes ductal anatomy easier to see, so any irregularities like dilation, filling defects, or intraductal changes become more detectable. Proper compression also helps reduce motion and blur, further sharpening visualization. The other ideas don’t fit as a general outcome: compression isn’t typically described as producing no change or dispersing debris, and while poor technique can introduce artifacts, the intended effect of good compression is to enhance visualization, not worsen it.
