Types of Ultrasound

Ultrasound imaging, also called ultrasound scanning or ultrasound test cost in Delhi, involves exposing part of the body to high frequency acoustic waves to produce images of the inside of the body. Ultrasound exams do not use ionizing radiation (used in X-rays). Because ultrasound images are captured in real time, they can show the structure and movement of the internal organs of the body, as well as the blood that flows through the blood vessels.

Ultrasound imaging is a non-invasive medical examination that helps doctors diagnose and treat medical conditions.Pelvic ultrasound produces images of the structures and organs of the lower abdomen or pelvis.

There are three types of pelvic ultrasound:

• abdominal (transabdominal)

• vaginal (transvaginal, intravaginal) for women

• rectal (transrectal) for men

A Doppler ultrasound examination may be part of a pelvic ultrasound examination.

The Doppler ultrasound is a special ultrasound technique that evaluates blood as it flows through the blood vessels, including major arteries and veins of the body found in the abdomen, arms, legs and neck.

Some of the common uses of the procedure

In women, a pelvic or abdominal ultrasound examination can help identify:

• bladder

• ovaries

• uterus

• Fallopian tube

Pelvic ultrasound is also used to monitor the health and development of the embryo or fetus during pregnancy (see page Obstetric Ultrasound).

Ultrasound exams can help diagnose symptoms experienced by women such as:

• pelvic pain

• abnormal bleeding

• other menstrual problems and help identify:

• Palpable formations such as ovarian cysts and uterine fibroids

• ovarian or uterine cancers

A transvaginal ultrasound test cost in Delhi is usually done to look at the endometrium or the walls of the uterus, including its thickness and ovaries. Transvaginal ultrasound is also a good way to evaluate the muscular walls of the uterus, called myometrium. Sono-hysterography allows an in-depth investigation of the uterine cavity. Usually, these tests are done to detect:

• uterine abnormalities

• scars

• endometrial polyps

• fibroids

• cancer, especially in patients with abnormal uterine bleeding

Some doctors also use hysterosonography for patients who suffer from infertility. See the Hysterosonography page for more information.In men, a pelvic or abdominal ultrasound is used to evaluate:

• bladder

• seminal vesicles

• prostate

Transrectal ultrasound, a special study that is usually performed to visualize the prostate, involves inserting a specialized transducer into a man's rectum. See the Prostate Ultrasound page for more information.

In men and women, a pelvic ultrasound examination can help identify:

• kidney stones

• tumors

• other conditions of the bladder

Pelvic ultrasound is also used to guide procedures such as aspiration biopsies, in which needles are used to extract a sample of organ cells for laboratory testing.

Doppler ultrasound imaging can help the doctor see and evaluate:

• obstructions in blood flow (such as clots)

• narrowing of blood vessels (which can be caused by plaque )

• tumors or congenital malformations

Structural ultrasound should be performed from week 18 to week 23, to confirm the absence of congenital effects, this being the most important.

Amniocentesis is a study to obtain a sample of the fluid surrounding the fetus with different purposes. It is done after week 15, in women with higher risk of chromosomal abnormalities.

Ultrasound 3D and 4D.

The first trimester is performed endo-vaginally and from week 26 to 30, at this stage the baby's features are known.
