normal ovary ultrasound


normal ovary ultrasound
Technology
This test can be done abdominally, transvaginally, or both. And imaging the abdomen tend to give more room for display, but less detail, especially for structures deep in the pelvis and partly hidden by the pubic symphysis. If abdominal scan, a full bladder is a useful and transmits sound very well through the water. In this case, and the bladder as a full voice "window" in the tub. Full bladder also helps to raise the structures of the basin so that from behind the symphysis and the view. If the survey transvaginally, and the full bladder makes the examination more difficult it is to pay the uterus and ovaries and tubes away from the vaginal adapter.
While the implementation of the scan, you may use the vaginal probe as if it were your fingers investigation, and pressure on different structures to see whether the tender or fixed in place. Similarly, you may not use your other had abdominal pressure, and thus structures closer to the investigation vaginalis. This type of dynamic ultrasound scanning can provide information that might miss otherwise.
Ultrasound changes
When you perform this type of scan, and modify various settings of the equipment can have a significant impact on improving the image and clarified in detail.
* An increase in the higher frequency ultrasound will give the best resolution, but poorer depth of penetration. In patients suffering from obesity, and the penetration depth is very important and the decision may need to be somewhat sacrificed in order to see all the structures.
* To increase the gain (amplification) will feature more echoes that appear on the screen, especially at the lower end of the picture, but the results an increase in gain more artifacts. This will reduce the gains and clear up some of the artifacts (especially in the public fibrosis), but with some loss of signal, especially in the depth of the tissue.
* Coordination can be variety of distances. Set focus just below the structure of the deeper you want to see clearly.
* Field of view can be widened or narrowed. And narrower field of vision, and generally the more the image quality was within the field.
Normal uterus
Starting from conception through the development of the uterus in a long axis. You should see the endocervical canal linking the tape lining of the uterus.
Measurement of the uterus in three dimensions, a length, width and depth.
Sweep the uterus both height and presentation, and evaluation of myometrium from the presence of fibroids. Small masses in the cervical fibrosis and cysts Nabothian and not of clinical importance.
Lining of the uterus
Lining of the uterus, or "tape", which differs in texture and thickness with cycyle menopause.
Cervical abnormalities
Fibroid is the most common abnormalities seen uterus using ultrasound. These masses are the latest round in the myometrium or drop out of the myometrium.
Normal ovaries
Normal ovaries appear lateral to the uterus, and differ in their relative position within the basin. In this example, the ovary lies in the position just above the classic ships. In other cases, it may be too far from the ovaries of this site.
During the reproductive years, and the ovaries and usually easily identified by the presence of small ovarian follicles. As mentioned the menstrual cycle, and many of the ovarian follicles are recruited and grow to 8-12 mm in diameter. Then, one dominant follicle is usually selected continues to grow in the 2-4 mm / day, even up to about 25 mm (22-30). Then it releases the egg and the partial collapse, luteum formation of the court.
If there is any internal bleeding in the cavity of bag, and corpus luteum takes on the irregular ", a piece of bread on the World Wide Web" appearance that resolves quickly. This is known as bleeding corpus luteum bag and innocent, though it has a somewhat disturbing emergence of ultrasound.
At menopause, and ovarian follicles are no longer growing and the ovary may become difficult to identify.
Similar results can be seen between the long-term users of the pill by mouth, although the changes are generally not dramatic.
Ovarian Abnormalties
There are a large number of cases of ovarian abnormalities to be seen, including abscesses, and solid tumors, and endometriomas.
