What is the M echo on ultrasound in gynecology? M echo during pregnancy, after childbirth, in menopause and brain

What does the m-echo indicator mean. Norms of the middle echo in gynecology. M-echo on the uzi of the head.

M-echo in gynecology is one of the objective indicators of the state of the endometrium, respectively, the woman's ability to become pregnant or havingshe has any health problems.
M-echo is determined during ultrasound examination of the uterine cavity. The doctor compares his thickness and structure with the existing physiological norms, indicating possible deviations from it.

What is the m echo on uzi in gynecology?

Endometrium is a functional mucous membrane of the uterine cavity that depends structurally from the menstrual cycle and its current phase, consisting of a basic and functional layer. This structure of blood vessels and glandular cells is formed under the influence of the action of female sex hormones.

IMPORTANT: The main function of the endometrium is to create conditions in the uterus that are favorable for implantation and fixation of a fertilized egg. After he participates in the formation of the placenta.

Endometrium.

M-echo determine the thickness of the endometrial layer of the uterus, and it changes in accordance with the days of the female cycle and is associated with a change in the hormonal level.

1. The onset of the cycle is called the proliferative or follicular phase when the mucosa grows
2. . In the middle of the cycle, the endometrium acquires the consistency of the sponge and becomes thicker under the action of progesterone
3. . If fertilization does not occur, the synthesis of estrogens and progesterone is inhibited, the functional endometrial layer is rejected

M - echo of the uterus: the norm by the days of the cycle

1. At the beginning of menstruation, the uterine cavity can expand to 5 mm. Heterogeneous hypoechoic or hypo-echogenic inclusions are fixed( these are blood clots).This phase usually lasts 3 or 4 days
2. During the proliferative phase, in the next 12 to 14 days, the endometrial size gradually increases. The increase is fixed at 0.1 mm daily. On ultrasound, the reduced echogenicity of the endometrium, its uniform structure is determined. Also, a bright hyperechoic band and a hypoechoic muscular layer of the uterus are determined, so the M-echo image is called a three-layer
3. . Then ovulation occurs, lasting from several minutes to several hours, on ultrasound it is elusive.
4. During the period of the period of the phase the echogenicity of the endometrium is increased, its echostructure is uniform. M-echo is 10-12 mm. It is five-layered because of the hyperechoic contour, visualized at the border of the mucous and muscular layers of the uterus
5. . The luteal phase often disappears the contour between the anterior and posterior walls of the endometrium. Echogenicity of the mucous layer increases, compared with the echogenicity of the muscle. M-echo increases, averaging 10 mm, maximum 15 mm

The m-echo index for ultrasound of the uterus varies depending on the phase of the menstrual cycle.

The thickness of the m-echo by the days of the cycle

The table shows the normal and allowable values ​​of the middle echo in women who have a standard 28-day cycle.

The middle echo on the days of the cycle.

IMPORTANT: If the cycle is longer, for example, 30 or 31 days, then some lag of the increase in the thickness of the endometrium is considered normal. If shorter, then, on the contrary, the m-echo grows faster

M-echo of the uterus in early pregnancy

If pregnancy occurs, the endometrium grows to a width of 20 mm or more.

IMPORTANT: Even if the fetal egg is not yet determined by ultrasound in the uterine cavity, by how the endometrium has grown, the gynecologist can determine the onset of the pregnancy

Unfortunately, this indicator can be present in pregnancy and the uterine and ectopic, because the sproutingThe endometrium is due to a sharp change in the hormonal level.
Also significantly increased the number of secretory cells and blood vessels, because in this early pregnancy period their function is similar to that of the placenta - to provide nutrition to the embryo.

M echo, norm for conception

For conception to occur, the M-echo should be 11-13 mm, this is enough for implantation.
This thickness is obtained by the endometrial layer by the 20th day of the cycle.

Implantation of the oocyte occurs at an endometrium thickness of 11-13 mm.

M echo after childbirth

After birth, the uterus continues to contract. A couple of days after birth, its size corresponds to the size of the uterus of an 18-week pregnancy, after 7 days - the correspondence of a 12-week pregnancy, by the sixth week it returns to its usual parameters.

M echo endometrium:

norm They are listed in the table:

Table 1.

Table 2.

M-echocardiosis: the norm during the menopause

The parameters of the middle echo of a woman in the menopause period differ from those established for women of childbearing age. This is associated with hormonal imbalance.
Ultrasound is determined by:

• highly echogenic endometrium
• its homogeneous structure
• even contours

With menopause up to 5 years, the mucous layer gradually thins down to 5 mm, then decreases to the point that it is not visualized at all.

IMPORTANT: A woman with an approaching menopause is recommended to undergo ultrasound about once every six months to prevent hyperplastic processes.

M-echo does not correspond to the phase of the loop: what is it?

Normal thickness of the endometrial layer means the possibility of the onset and development of pregnancy. It is recommended to carry out hormone therapy, because otherwise the pregnancy may not occur.

The increased thickness of m-echo means the need for further studies of the condition of a woman in order to avoid the development of pathological conditions.

M-echo of the head to the child, adult:

norm With the help of echoenceology, doctors examine the brain, determining its sensitivity to ultrasound. In children, this procedure is more informative, since they have a much thinner bones of the skull.
Echoenceology is performed in one-dimensional and two-dimensional modes.
Evaluating with the help of the M-echo how the middle structures of the brain are displaced, physicians determine the normal or asymmetric arrangement of the brain regions.
