Myometrium shows intermediate signal intensity on T2-weighted images.
Placenta Percreta--placenta invades through the
myometrium upto the uterine serosa and may include invasion into other pelvic organs like bladder, round ligament, vagina and so on.
The significant (P<0.05) reduction was seen in the uterine histometry including epithelial height, endometrium thickness and its glands area, inner circular and outer longitudinal smooth muscle thickness of
myometrium in the diabetic rats.
The distance to the serosal surface was 2 mm and deep penetration to
myometrium was detected.
Heterotopic cartilage in the
myometrium is usually asymptomatic and an incidental finding, but may present with abnormal bleeding, infertility, subfertility and abortion.
The volumes of the total uterus, the total
myometrium and the endometrium with transvaginal ultrasonography were calculated using the Ellipsoid formula (volume=0.523x length x depth x width).
The IOD of GHR in the
myometrium, luminal epithelium, glandular epithelium, and whole uteri of weaning gilts showed significant linear (p<0.001) and quadratic (p<0.05) increases with an increasing level of ZEA (Table 4).
Human
myometrium was obtained (with institutional Research and Ethics Committee approval) from the upper margin of the lower uterine segment incision during Caesarean section.
Previous studies [11, 12] have proposed that undifferentiated cells are involved in myometrial pathologies, and also leiomyoma onset may be the result of impaired function, proliferation, and differentiation of undifferentiated cells inside the
myometrium that are under the effect of ovarian hormones [13,14].
It depends on wound healing that can be affected by various factors such as the method and tools used for uterine incision, unsuccessful hemostasis and closing of the myometrial defect [15], the extent of local tissue destruction, the potential formation of infection or hematoma within the
myometrium, gas pneumoperitoneum in laparoscopic procedures, and, finally, the individual characteristics of the healing process related to the production of growth factors or excess collagen deposition [6].
Sagittal and axial T1- and T2-weighted images demonstrated a gestational sac bulging through the
myometrium of the lower uterine segment in the region of Cesarean section scar (Figure 4).
Abnormal vasculature adjacent to the uterus on imaging may represent penetration of the placenta through the uterus or mere recruitment and enlargement of separate vessels beyond to enhance blood supply to the
myometrium. The guideline discusses magnetic resonance imaging findings and Doppler findings (grey scale, colour and three-dimensional power Doppler) that cast light on the extent of invasion.
