A 23-year-old woman presents with complaints of right lower quadrant pain. During bimanual examination, an enlarged right ovary is suspected, and transvaginal sonography reveals this a simple ovarian cyst. What sonographic feature, demonstrated here, is characteristic of cysts?

++
++
++
++

a. Acoustic window

++
++

b. Acoustic shadowing

++
++

c. Acoustic enhancement

++
++

d. Tip of the iceberg sign

A 40-year-old woman presents with complaints of heavy menstrual bleeding. During examination, an irregularly contoured uterus is palpable, and transvaginal sonography demonstrates multiple leiomyomas. What sonographic feature, as demonstrated here, is characteristic of dense structures?

++
++
++
++

a. Acoustic window

++
++

b. Acoustic shadowing

++
++

c. Acoustic enhancement

++
++

d. Tip of the iceberg sign

++
++ ++
++
++

Which of the following is NOT a relative or absolute contraindication to transvaginal sonography?

++
++
++

a. Patient refusal

++
++

b. Imperforate hymen

++
++

c. Postpartum status

++
++

d. Strictured introitus

++
++ ++
++
++

Which of the following is NOT a characteristic of the Doppler technology illustrated below?

++
++
++
++

a. Scaling of color

++
++

b. Most sensitive to low-flow velocities

++
++

c. Directionality of blood flow with dual colors

++
++

d. Quantitative measurement of impedance to red blood cell velocity

++
++ ++
++
++

Power Doppler imaging differs from color Doppler mapping in which of the following ways?

++
++
++

a. Only power Doppler maps red blood cell motion.

++
++

b. Color Doppler is more sensitive to low-flow velocities.

++
++

c. Power Doppler gives no information regarding blood flow direction.

++
++

d. All of the above
