4.3.1\ Method

The patient should void the urinary bladder. Probe is placed in the vagina, multi-plane scan is carried out from sagittal section to coronal section. Located at the uterus bilateralis.

4.3.2\ Section Structure

The corpus luteum is shown as round or oval in this plane and thick capsule wall and echoless or network echo inside. Sometimes there are floating echoes in the capsular space when the probe touches the cyst.

4.3.3\ Measuring Method and Normal

The size and echo of the corpus luteum vary largely, and the sonogram is even complex when there is bleeding in the capsular space, so it is easy to be confused with ovary tumor, so careful identification should be taken.

4.3.4\ The Clinical Application Value

The corpus luteum is a physiologic cyst. It could vanish by itself. If the ultrasound exam can give a clearly differential diagnosis to tumor, the corpus luteum does not need to be operated.
