"After parturition, the uterus nearly regains its usual size, weighing about 42 g. Its cavity is larger than in the pre-pregnancy state, its vessels are tortuous, and its muscular layers are more defined. The external orifice is more marked, and its edges present one or more fissures."
"type 1: thick or thin sub-endometrial enhancement, most commonly found in pre-menopausal women"
"type 2: diffuse myometrial enhancement, found in both pre and post-menopausal women"
"type 3: faint diffuse myometrial enhancement, exclusively found in post-menopausal women"
"There is some physiologic variability to the myometrial zonal appearance. The junctional zone is less distinct pre-menarche and during pregnancy 4. In the postmenopausal patient, the outer myometrium is thinner and of lower signal due to reduced fluid content and therefore approximates the junctional zone, with poor delineation of the margin in some patients."
"In the fetus, the uterus is contained in the abdominal cavity, projecting beyond the superior aperture of the pelvis. The cervix is considerably larger than the body."
"At puberty, the uterus is pyriform in shape and weighs from 14-17 g. It has descended into the pelvis, the fundus being just below the level of the superior aperture of this cavity. The palmate folds are distinct and extend to the upper part of the cavity of the organ."
"During menstruation, the uterus is enlarged, more vascular, and its surfaces rounder; the external orifice is rounded, its labia are swollen, and the lining membrane of the body thickened, softer, and of a darker colour."
"During pregnancy, the uterus becomes enormously enlarged, and by the eighth month, it reaches the epigastric region. The increase in size is partly due to the growth of pre-existing muscles and partly to the development of new fibres."

"In old age, the uterus becomes atrophied and paler and denser in texture; a more distinct constriction separates the body and cervix. The internal orifice is frequently, and the external orifice is occasionally obliterated, while the lips almost entirely disappear."

"The normal uterus lies between the bladder and rectum and myometrial attenuation is between 30-50 HU depending on age and hormonal influences. The endometrial complex is relatively hypoattenuating to myometrium and this difference persists following IV contrast medium injection. The myometrium typically enhances earlier and more intensely 2. The enhancement pattern is variable 7:"
"The transabdominal US allows evaluation of the size and position of the uterus in the pelvic cavity. The transvaginal US allows the internal structure of the uterus to be examined 2."

"The uterine length is measured in the midsagittal plane from the outer serosal surface of the fundus to the external cervical os. The uterine height (AP) is measured in the midsagittal plane anteroposteriorly from outer to outer serosal surfaces. The uterine width is measured in the transverse plane. The uterine body length is measured in the midsagittal plane from the fundal outer serosal surface to the internal os. The uterine cervix length is measured in the midsagittal plane from the internal os to the external os."
"On contrasted MRI study, myometrium shows homogenous hyperintensity on arterial and venous phases. Meanwhile, endometrium enhances slowly and is more hypointense when compared to myometrium 7."

"These variable enhancement patterns could be due to differences in age, parity and menstrual status. The basal layer of endometrium adjacent to the myometrium could contribute to thin sub-endometrial enhancement. Thick sub-endometrial enhancement could be due to the junctional zone. Meanwhile, diffuse myometrial enhancement could be due to the density of smooth muscles and blood vessels in the myometrium that affects the uptake of contrast 7."
