ARDMS BREAST REGISTRY EXAMS WITH ACTUAL CORRECT QUESTIONS AND VERIFIED DETAILED ANSWERS ALREADY GRADED A+

ARDMS BREAST REGISTRY EXAMS WITH ACTUAL CORRECT QUESTIONS AND VERIFIED DETAILED ANSWERS ALREADY GRADED A+ Artifact - Correct Answer An echo feature present or absent in a sonographic image that does not correspond to the presence or absence of a real structure. Eg. enhancement or shadowing. Attenuation - Correct Answer The reduction of intensity (and amplitude) of a sound wave as it travels through a material. Attenuation is due to absorption, reflection, and scattering. Complex - Correct Answer A structure in the body that contains both cystic and solid components. Echogenic - Correct Answer A structure or medium that produces echoes. Edge Shadowing - Correct Answer Decreased echo amplitude distal to the edge of a structure. This artifact results from refraction of the sound beam. Enhancement - Correct Answer Increased echo amplitude returning from regions lying beyond an object that causes little or no attenuation of the sound beam (typically a cystic structure). This artifact results in a brighter than normal appearance.
