On what day of the cycle do gynecological ultrasound of the uterus

Ultrasound examination allows you to obtain accurate information on the state of internal organs. This procedure is often performed to detect gynecological problems. However, the method is as informative only if it is carried out in a certain period of the menstrual cycle. Therefore, you should find out in advance which days are best to do pelvic ultrasound.

On what day of the cycle is better to do ultrasound

Ultrasound of the uterus do after 3-5 days after the menstrual period is completed. The optimal period is 7 day cycle. Doctors recommend to carry out research not later than 10 days from the start of the critical days.

The reasons for restrictions

Explanation of what makes ultrasound after a month, quite simple. During this period, the endometrium, blanketed the interior of the genitals, very thin. Accordingly, it is possible to carefully consider the condition of the uterus, determine the trend of a stock layer identify pathological changes.

In the second phase the endometrium grows substantially becomes excessively thick. Therefore, to detect cysts, fibroids and other tumors is problematic. They simply hide behind the mother layer.

Is it possible to do ultrasound before menstruation

Ultrasound before menstruation, as a rule, is not carried out. During this period, the study is not able to show the exact state of the reproductive system. However, sometimes resorting to unscheduled inspection. Then it is already taken into account is not the day of the cycle. Among the indications for its conduct distinguished:

• infertility;
• delay or absence of menstruation;
• irregular periods;
• beginning uterine bleeding;
• uncharacteristic vaginal discharge;
• strong pain in the lower abdomen;
• excessive increase in the size of genitals, identified during the inspection on the gynecological chair.

The optimal time of

The decision as to what day of the cycle to do ultrasound, the doctor takes on an individual basis. In many ways, the period of the procedure depends on the aim pursued.

To determine the ovulation

gynecological US considered the best way to determine the period of ovulationand. It is used for problems with fertilization, during the preparation for IVF and in the diagnosis of infertility. The procedure in this case is carried out several times. This is due to difficulties with the identification of the dominant follicle.

As a rule, the first time a study is carried out on 8-13 day cycle. At this point, the follicle size is 15 mm. The second time, ultrasound is performed on day 14-15. As a rule, with a stable cycle of ovulation during this period. follicle size in this case reaches 20 mm. After that marked his break and complete disappearance.

If you suspect a disease of the pelvic organs

Identify cysts and fibroids easier to just a few days after the critical days. However, ultrasound in gynecology are not always carried out in this period. For example, for suspected endometriosis procedure is performed twice. The first time it is prescribed for 5-7 hours since coming regulation. Retesting is recommended at 26-28 day cycle, just before the critical days.

To determine the condition of the ovaries and identify irregularities in their work, ultrasound do repeatedly:

• 5 day cycle. Can be measured to assess the reserves and morphology. Appendages still in a state of rest;
• 8-10 hours. At this time there is a late follicular phase;
• 14-16 days. The period witnessed early ovulatory phase;
• 22-24 hours. Study during the luteal phase.

Through an integrated approach possible to trace all stages of follicular development and corpus luteum. Due to this, exactly determine the chances of conception.

Holding ultrasound during menstruation

Strict contraindications for the procedure during the critical days there. However, routine screening is not assigned at this time. Due to the presence of blood in the genital organs inspection becomes much more complicated. Overview is limited. Accordingly, the procedure is not sufficiently informative.

To implement the US during the month resorting in case of emergency. it also shows in this period in the preparation of ECO. Thanks to its conduct can not determine how many follicles located in the ovaries.

What does the survey

The study can not determine:

• structure, size and position of the genitals, and the thickness of its walls;
• the number of follicles and their exact dimensions;
• growth of tumors in the ovaries and uterus.

Any deviation from the norm signal the presence of disturbances. Among the pathological features, which are revealed in the course of the ultrasound, is isolated:

• thickening of the fallopian tubes. It indicates the beginning of an increased risk of malignancy;
• oval or round objects. Most likely, this fibroids or cysts;
• a reduction in the size of genitals and increase appendages. As a rule, these changes indicate polycystic;
• change in echogenicity. Fixed in endometriosis and uterine fibroids.

Basic rules ultrasonic parameters

Special attention should be normal levels of study:

• genital organ is located in the central part of the pelvis, is closer to the front wall;
• a longitudinal scanning uterus pear-shaped, and transverse - ovoid;
• echogenicity genitals average. its inner homogeneous structure;
• ovary has an oval shape. It is noted the presence of inclusions within the body ehogenativnyh;
• endometrial depends on the phase of the cycle. Therefore, when drawing up the protocol required to indicate which is the period surveyed.

Thanks to an ultrasound can not identify a variety of violations of the female reproductive system. The main thing is to choose the date for the implementation of these procedures. Only under this condition, accurate information is received.
