[wptab name=’Ultrasound Study’]
What is an Ultrasound?
An ultrasound is the use of sound waves to obtain a medical image or picture of various organs, tissues, vessels, tendons, and joints in the body. It is a painless and safe procedure.
Ultrasounds produce very precise images of your tissues (heart, blood vessels, uterus, bladder, etc.) and reveals internal motion such as heart beat and blood flow. It can detect diseased or damaged tissues, locate abnormal growths, and identify a wide variety of changes in conditions, which enables your doctor to make a quick and accurate diagnostic.
An ultrasound is sometimes used in therapeutic applications for soft tissue injuries. It is also helpful in pre-natal care to determine age, sex, and growth characteristics of the unborn child.
What Will the Ultrasound Exam be Like?
The individual that will be performing the ultrasound study on you is known as a sonographer. This technologist is highly skilled, educated and works under close supervision with a radiologist. The radiologist is a physician who specializes in the study of various imaged tests such as x-ray, ultrasound, mammography, CT, MRI, and nuclear medicine. The radiologist will monitor the exam as it progresses to assure that the most accurate results are obtained from your examination.
The technologist will assist you on the examination table. At this time, an oil transmission gel will be applied to the area of your body that will be examined. A transducer will be moved slowly over the body part been imaged. The transducer sends a signal to an on-board computer, which processes the data and produces the ultrasound image. It is from this image that the diagnostic is made.
You won’t feel a thing except for the slight pressure and movement of the transducer over the part of the body being imaged. It is important that you remain still and relaxed during the procedure. The ultrasound images will appear on a monitor similar to a TV screen and are recorded either on paper or film for a detail study.
How Long Will the Exam Take?
Probably about 30 to 60 minutes, depending upon the study being performed. You may be required to drink water to enhance the quality of the picture (sound travels better through water) and this could lengthen the time of the exam.
How will I Learn the Results?
The results will be made available to you from your designated health care provider, practitioner, or radiologist depending upon who was your initial contact.
- Avoid wearing jewelry.
- Follow all instructions received prior to the examination.
- Avoid soft drinks before exam. Carbonated drinks develop bubbles that may interfere with the image.
- Be sure to ask any questions relating to your examination.
Echocardiogram with Doppler
An echocardiogram (also called an echo) is a type of ultrasound test that uses high-pitched sound waves that are sent through a device called a transducer. The device picks up echoes of the sound waves as they bounce off the different parts of your heart. These echoes are turned into moving images of your heart that can be seen on a video screen and analyzed.
Doppler echocardiogram. This test is used to look at how blood flows through the heart chambers, heart valves, and blood vessels. The movement of the blood reflects sound waves to a transducer. The ultrasound computer then measures the direction and speed of the blood flowing through your heart and blood vessels.
Tissue Doppler w/color flow
[wptab name=’Breast Ultrasound’]
Mammography is an early detection tool for breast cancer that is known to reduce deaths due to breast cancer. Even so, mammograms do not detect all breast cancers. Some breast lesions and abnormalities are not visible or are difficult to interpret on mammograms. Many studies have shown that ultrasound and magnetic resonance imaging (MRI) can help supplement mammography by detecting breast cancers that may not be visible with mammography.
During a breast ultrasound examination the sonographer or physician performing the test may use Doppler techniques to evaluate blood flow or lack of flow in any breast mass. In some cases this may provide additional information as to the cause of the mass.
Breast Ultrasound Images
[wptab name=’Prostate Ultrasound’]
Prostate ultrasound, also called transrectal ultrasound, provides images of a man’s prostate gland and surrounding tissue. During the procedure a sound wave emitting device, known as a TRUS probe, is inserted into the rectum. For this, an ultrasound gel is applied to the probe which is covered in a sheath. It emits sound waves that bounce off various organs including the prostate. From the reflected sound waves, an image of the prostate is created. This procedure can detect irregularities missed by other procedures. It also reveals the size of the prostate.
[wptab name=’Renovascular Ultrasound’]
A vascular ultrasound provides pictures of the body’s veins and arteries. A Doppler ultrasound study is usually part of a vascular ultrasound examination. Doppler ultrasound is a special ultrasound technique that evaluates blood flow through a blood vessel, including the body’s major arteries and veins in the abdomen, arms, legs and neck.
Color Doppler ultrasound (CDUS) is an effective imaging technique for the diagnosis of renal vascular diseases. It is already the modality of choice for the detection of acute renal vein thrombosis and nonocclusive intrarenal vascular disorders including iatrogenic arteriovenous fistula and false aneurysm, particularly in patients with impaired renal function that precludes the use of iodinated contrast agents.
Using Duplex/color Doppler sonography is an excellent means of evaluating renal artery disease, which is not an infrequent cause of hypertension and end-stage renal disease. It has high sensitivity and specificity, when compared with contrast-enhanced angiography, in the diagnosis of RA stenosis on the basis of Doppler samples obtained from extrarenal arteries (using measurements of peak systolic velocity [PSV] and renal-aortic ratio).
Renovascular Ultrasound Images
[wptab name=’Vascular Ultrasound’]
A vascular ultrasound is a noninvasive ultrasound method (also called a duplex study) used to examine the circulation in the blood vessels in different areas around the body.
Vascular ultrasound can be used to evaluate veins or arteries in nearly any part of the body, including blood vessels in the neck, abdomen, arms and legs. Non- invasive means the procedure does not require the use of needles or anesthesia. Unlike other imaging tests, ultrasound does not require radiation or contrast dye.
During a vascular ultrasound study, sound waves are transmitted through the tissues of the area being examined. These sound waves reflect off of blood cells moving within the blood vessels, and return to the ultrasound machine. The sound waves are recorded and displayed on a computer screen to make an image of the blood vessel. The speed of the sound waves returning to the ultrasound machine allow for calculation of the speed of blood flow in the vessel.
Sonography is a useful way of evaluating the body’s circulatory system. Vascular ultrasound is performed to:
- Help monitor the blood flow to organs and tissues throughout the body.
- Locate and identify blockages (stenosis) and abnormalities like plaque or emboli and help plan for their effective treatment.
- Detect blood clots (deep venous thrombosis (dvt) in the major veins of the legs or arms.
- Determine whether a patient is a good candidate for a procedure such as angioplasty.
- Evaluate the success of procedures that graft or bypass blood vessels.
- Determine if there is an enlarged artery (aneurysm).
- Determine the source and severity of varicose veins.
- In children, ultrasound is used to:
- Aid in the placement of a needle or catheter into a vein or artery to help avoid complications such as bleeding.
- Evaluate a connection between an artery and a vein which can be seen in congenital vascular malformations (arteriovenous malformations or fistula) and in dialysis fistula.

OB/GYN – Transabdominal & Transvaginal Ultrasound
OB/GYN sonography is a method of obtaining images of internal organs by sending sound waves into the body. The reflected sound waves are returned as echoes. These sound waves are then recorded and displayed as a real-time visual image. OB (obstetric) sonography refers to the use of ultrasound to visualize and determine the condition of a pregnant woman and her fetus.
An OB sonogram is one of the more well-known uses of sonography: examining the fetus of a pregnant woman. Ultrasound scan is considered to be a safe, non-invasive, accurate and cost-effective investigation in the fetus. It has progressively become an indispensable obstetric tool and plays an important role in the care of every pregnant woman.
A GYN sonogram evaluates organs found within the female pelvic region. A GYN sonogram can help identify ovarian cysts, uterine fibroids, as well as ovarian or uterine masses. A pelvic sonogram can be done transabdominal and transvaginal/endovaginal. Transvaginal ultrasound is performed very much like a gynecologic exam and involves the insertion of the transducer into the vagina. A transvaginal ultrasound is usually performed to view the endometrium or the lining of the uterus, including its thickness and ovaries.
[wptab name=’Pediatrics Ultrasound’]
An ultrasound is a picture taken with sound waves of the tissues and organs inside your child’s body. The procedure is noninvasive, meaning it will not hurt the child. Ultrasounds give doctors important information about certain areas inside your child’s body that they cannot learn from a physical examination. The length of time needed to do each ultrasound varies depending on the kind of ultrasound that has been ordered for your child.
A Doppler ultrasound study may be part of a child’s abdominal ultrasound examination. Doppler ultrasound is a special ultrasound technique that evaluates blood flow through a blood vessel, including the body’s major arteries and veins in the abdomen, arms, legs and neck.
Abdominal ultrasound images can be used to help diagnose appendicitis in children, appendicitis is the most common reason for emergency abdominal surgery. An abdominal ultrasound imaging is performed to evaluate the:
The Parent’s Role During the Test
We welcome your help and support during this test. Two parents or guardians are invited to join your child in the examination room. Other adults and children must wait in the waiting room. The ultrasound technologist will show you where to sit or stand in the examination room during the test. Please follow the instructions of the medical staff performing the test.
- The most important role of a parent during the test is to help your child stay calm and relaxed. The best way to help your child stay calm is for you to stay calm.
- It is important that your child remains still when the ultrasound pictures are being taken.
- We encourage you to talk to your child and hold his or her hand.
- Please do not distract the medical team or interrupt the test in any way.
- We welcome your questions, but please ask them either before or after the test.
What will my child experience during and after the procedure?
Ultrasound examinations are painless, fast and easily tolerated by most patients. Your child will lie on his or her back on an examining table. The radiologist or sonographer will spread warm gel on the skin, then press and move the transducer firmly against the abdomen, moving it back and forth until the desired images are captured. There may be minimal discomfort from pressure as the transducer is pressed against the area being examined.
[wptab name=’Pediatric Echocardiography’]
An echocardiogram is a test that uses high-frequency sound waves (ultrasound) to create an image of the heart’s internal anatomy. Pediatric echocardiography is mainly used for the detection of congenital heart defects in children. It is also used for the evaluation of murmurs and is an essential tool to evaluate the effectiveness of medical therapy and surgical treatments. Three-dimensional echocardiography is often combined with Doppler ultrasound and color Doppler ultrasound to provide a more comprehensive evaluation of the heart. Echocardiography is the use of ultrasound to examine and measure the structure and functioning of the heart.
About 40,000 children are born with a heart defect each year. Most of these children can benefit from surgery even if the defect is severe. When surgery is necessary, many medical treatments are available to help the heart work properly.
The two types of heart disease in children are “congenital” and “acquired.” Congenital heart disease (also known as a congenital heart defect) is present at birth. Some defects in this category are patent ductus arteriosis, atrial septal defects and ventricular septal defects. Acquired heart disease, which develops sometime during childhood, includes diseases such as Kawasaki disease, Rheumatic Heart Disease (RHD), and infective endocarditis.
Cardiovascular Diagnostic Image offers pediatric echocardiography servicers for children under age eighteen, both inpatient and outpatient. A routine pediatric echo can be expected to take an hour, but special circumstances could require longer. Echocardiography is useful for assessing cardiac anatomy and function, including sources of murmur, or whether breathing issues are cardiac related.
