Normal size of endometrium in mm
Endometrial thickness is a commonly measured parameter on routine gynecological ultrasound and MRI. The appearance, as well as the thickness of the endometrium, will depend on whether the patient is of reproductive age or postmenopausal and, if of reproductive age, at what point in the menstrual cycle they are examined.
Radiographic features
Ultrasound
The endometrium should be measured in the long axis or sagittal plane, ideally on transvaginal scanning, with the entirety of the endometrial lining through to the endocervical canal in view 10.
The measurement is of the thickest echogenic area from one basal endometrial interface across the endometrial canal to the other basal surface. Care should be taken not to include hypoechoic myometrium or intrauterine fluid in this measurement.
The normal endometrium changes in appearance as well as in thickness throughout the menstrual cycle:
in the menstrual and early proliferative phase it is a thin, brightly echogenic stripe comprising of the basal layer; minimal fluid can be appreciated endovaginally within the endomet
