Uses and Limitations of Abdominal Ultrasound, Vascular Ultrasound and Sonohysterography

What exactly is abdominal Ultrasound?

A list of the organs and diseases that are suitable for examination using abdominal ultrasound is long. Abdominal ultrasounds employ the transducer probe that has a larger footprint and lower frequencies to penetrate deeper and create images of huge structures and tissue areas. After the gel is placed on the probe, it is placed directly on the abdomen. Although the scan can be uncomfortable and could require the patient be able to empty their bladder, it’s not painful. Abdominal ultrasounds are in many instances the most preferred method of diagnosis because it’s fairly safe, efficient and non-invasive.Ayrıntılı Ultrason Ankara

Anomaly Limitations Ultrasound

However abdominal sonography scans create less-than-high-resolution images, with a low clarity. They also aren’t great in revealing organs that are air-filled or which are obscured from the intestinal tract, that has air. In those instances the use of the use of an MRI, CT scan or barium test could be the best diagnostic tools. Another drawback is that patients with large quantities of tissues that sound waves have to be able to pass are more difficult to detect as the sound waves are weaker the greater amount of tissues they have to penetrate on path to abdominal structures deep.Renkli Doppler

What is Vascular Ultrasound?

Vascular Ultrasound is used to examine the arteries, veins, and blood flow throughout the body. Vascular sonographers use ultrasound to identify plaques embolisms, blood clots blockages, and other similar issues. Vascular sonography can identify deep venous thrombosis. This refers to the existence of blood clots within the major veins of the leg or arm. It helps doctors determine whether patients are candidates for angioplasty or other procedures prior to undergoing the procedures. Following arterial bypass surgery, or other medical procedures the use of vascular ultrasound for follow-up evaluation, and sometimes right within the operating area. Additionally, this type of ultrasound is able to detect an aneurysm that has grown in size or an artery and enable the thorough examination of varicose veins.

Children’s vascular ultrasound images can assist medical practitioners in successfully inserting needles and catheters into the smaller blood vessels of children, thereby reducing the chance of bleeding and massive clot formation. They also assist medical professionals determine the artery-to-vein connection when there are birth defects in the blood vessels.

Vascular Ultrasound: Limitations

Vascular sonography is limited in its capability to capture images of blood vessels that are located in the body’s deepest parts or smaller vessels at any area. It is possible that a CT scan MRI and other special test could be required for obtaining clear images of these vessels. Another drawback is that ultrasound waves could be prevented from entering into areas in which atherosclerosis has led to calcification within the arteries. In some instances ultrasound cannot identify a vessel with a slight obstruction as one which is completely blocked. Additionally the procedure requires an ultrasound technologist as well as an interpreter doctor with specific knowledge and certification in the field of vascular ultrasound.

What exactly is Sonohysterography?

Sonohysterography is also known as hysterosonography, or saline infusion sonography, is one type of pelvic ultrasound that involves scanning the inside of the uterus of a woman using an transvaginal probe that is inserted into the vagina. To get images of the ultrasound area the baseline scan is followed by a uterus scan. The inside of the uterus is infected with sterile saline and scans are rescanned. The saline fluid expands the uterus and exposes the lining of the endometrial sac to allow it to be properly examined. This procedure is utilized to determine vaginal bleeding abnormalities that is caused by polyps, fibroids or scarring, endometrial atrophy tumors or lesions and congenital disorders.

Sonohysterography can also be helpful in determining the root problems with pelvic or pelvic organs, such as infertility, and multiple miscarriages. When air and saline are injected together it allows the study of air bubbles inside the fallopian tubes, which can aid in identifying abnormalities in these structures. Ultrasound is also used to investigate blood-related issues like clots, blood supply in tumors , the pelvic aneurysms and pelvic varicose veins.

Restrictions of Sonohysterography

Sonohysterography can’t be performed in women suffering from chronic pelvic inflammation. It is not recommended during pregnancy. The procedure is generally done one week after menstrual cycle to limit the risk of infection, and also because it’s the most appropriate time of the menstrual cycle to evaluate the uterine lining or the endometrium. It is not easy to perform on women suffering from cervical narrowing or stenosis. There is also the possibility of the procedure might not stretch the uterus enough to obtain clear images. This could happen if fibroids or uterine scarring have caused damage to a part of the uterine cavity.
