Chapter 42 - Doppler Evaluation

Which technique involves rotation of the transducer 90° to obtain coronal images?

What is the most anterior pelvic organ seen on sagittal ultrasound?

Which view best shows the long axis of the uterus?

The ________________ view best measures uterine length from fundus to cervix.

What does the internal os separate?

What scan plane is used when the transducer is rotated 90 degrees from sagittal?

Sonohysterography uses sterile saline to evaluate the endometrium.

Which muscle is hammock-shaped and seen inferior to the bladder?

What happens to the resistive index (RI) just before menstruation?

A filled bladder displaces bowel and acts as an acoustic window.

Endometrial thickness is measured from the interface of the ________________ layer.

Which view is best to identify Nabothian cysts?

What artifact is commonly seen posterior to the endometrium during the secretory phase?
