DIAGNOSTIC IMAGING SERVICES

ODI offers a comprehensive range of diagnostic imaging services which reap various benefits for patients and physicians alike. Our on-site, high-tech ultrasound equipment and highly trained technicians provide an enhanced approach to diagnostics and medical management for quality care.

WHAT WE DO

There are various types of ultrasounds which can be conducted to monitor and evaluate patients’ health and wellbeing.

Ultrasound (also called sonography or ultrasonography) is a noninvasive diagnostic imaging test. It uses high-frequency sound waves to create real-time pictures or video of internal organs or other tissues, such as blood vessels. An ultrasound picture is called a sonogram. Ultrasound enables healthcare providers to “see” details of soft tissues inside the body without making any incisions.

OUR ULTRASOUNDS

Carotid Ultrasound

Carotid (kuh-ROT-id) ultrasound is a safe, painless procedure that uses sound waves to examine the blood flow through the carotid arteries. Your two carotid arteries are located on each side of your neck. They deliver blood from your heart to your brain. Carotid ultrasound tests for blocked or narrowed carotid arteries, which can increase the risk of stroke. The results can help your doctor determine a treatment to lower your stroke risk.

A carotid ultrasound is performed to test for narrowed carotid arteries, which increase the risk of stroke. Carotid arteries are usually narrowed by a buildup of plaque — made up of fat, cholesterol, calcium and other substances that circulate in the bloodstream. Early diagnosis and treatment of a narrowed carotid artery can decrease stroke risk.

Echo/Aorta Duplex

An echocardiogram uses sound waves to produce images of your heart. This common test allows your doctor to see your heart beating and pumping blood. Your doctor can use the images from an echocardiogram to identify heart disease.

Types of Echocardiograms:

Transthoracic echocardiogram

In this standard type of echocardiogram:
· A technician (sonographer) spreads gel on a device (transducer).
· The sonographer presses the transducer firmly against your skin, directly over your heart.
· The transducer records the sound wave echoes from your heart.
· A computer converts the echoes into moving images on a monitor.

If your lungs or ribs block the view, you may need a small amount of an enhancing agent injected through an intravenous (IV) line. The enhancing agent, which is generally safe and well tolerated, will make your heart's structures show up more clearly on a monitor.

Doppler echocardiogram

Sound waves change pitch when they bounce off blood cells moving through your heart and blood vessels. These changes (Doppler signals) can help your doctor measure the speed and direction of the blood flow in your heart.

Doppler techniques are generally used in transthoracic and transesophageal echocardiograms. Doppler techniques can also be used to check blood flow problems and blood pressure in the arteries of your heart — which traditional ultrasound might not detect. The blood flow shown on the monitor is colorized to help your doctor pinpoint any problems.

Abdominal Ultrasound

There are several types of ultrasound tests. Each uses a probe designed to image specific areas of the body. An abdominal ultrasound shows organs and other soft tissues (such as blood vessels) inside your abdomen (belly).

How does abdominal ultrasound work?

For an abdominal ultrasound test, a trained medical professional (sonographer) applies a special gel to your belly. The sonographer then moves the probe over the gel.

Sound waves from the probe go through your skin and bounce back from soft tissues (such as organs). Real-time (live) images show up on a computer screen nearby.

What body parts does an abdominal ultrasound evaluate?

Your provider orders ultrasound evaluation of specific areas of your abdomen. A right upper quadrant ultrasound examines three organs of the digestive system:
- Liver
- Pancreas
- Gallbladder

A complete abdominal ultrasound examines those three organs and adds the:

- Kidneys
- Spleen
- Bladder
- Abdominal blood vessels (such as the inferior vena cava and the aorta)

Renal Duplex

A kidney ultrasound (renal ultrasound) is an imaging test that allows your healthcare provider to look at your right and left kidney, as well as your bladder. The kidneys are the filtration system of your body. They filter the waste products out of your blood. The waste products then leave your body as urine.

Your healthcare provider may also need a "post-void" done with this exam. This requires you to come to the test with a full bladder so that the provider can get a volume of your bladder before and after you empty it.

What happens during the kidney ultrasound

During the kidney ultrasound, you will be asked to lie on a padded examining table. The provider performing the ultrasound will apply a warm, water-soluble gel to your skin over the area that's being examined. This gel won't harm your skin or stain your clothes. A probe is then gently applied against your skin. You may be asked to hold your breath several times or roll on your side during the test. Typically, the ultrasound will take about 20 to 30 minutes to complete

Pelvic Ultrasound

1. Male (Transabdominal)
2. Female (Transabdominal/Transvaginal)

A pelvic ultrasound looks at the organs in your pelvic area between your abdomen (belly) and legs. It may also look at your lower abdomen. The pelvic organs include:

- Bladder, which holds urine
- Fallopian tubes, which carry eggs between the ovaries and uterus
- Ovaries, organs that make and store eggs
- Prostate, a gland that helps with reproduction in men
- Rectum, the lower part of your intestines
- Uterus, also called the womb
- Vagina, the canal to the uterus.

There are different types of pelvic ultrasounds. Each looks at different organs or serves a particular purpose:

- Abdominal ultrasound, which examines organs from outside the belly
- Pregnancy ultrasound, which watches a baby’s growth in the uterus (womb)
- Rectal ultrasound, which examines the inside of the rectum. A special exam called a transrectal ultrasound looks at the prostate
- Transvaginal ultrasound, which examines the reproductive organs from inside the vagina.

Scrotal Ultrasound

Ultrasound imaging of the scrotum uses sound waves to produce pictures of a male's testicles and surrounding tissues. It is the primary method used to help evaluate disorders of the testicles, epididymis (tubes immediately next to the testicles that collect sperm) and scrotum. Ultrasound is safe, noninvasive, and does not use ionizing radiation.

Ultrasound imaging of the scrotum is the primary imaging method used to evaluate disorders of the testicles, epididymis (tubes immediately next to the testicles that collect sperm made by the testicle) and scrotum.

This study is typically used to:

- determine whether a mass in the scrotum felt by the patient or doctor is cystic or solid and its location
- diagnose results of trauma to the scrotal area
- diagnose causes of testicular pain or swelling such as inflammation or torsion
- evaluate the cause of infertility such as varicocele
- look for the location of undescended testis

Ultrasound also can be used to locate and evaluate masses (lumps or tumors) in the testicle or elsewhere in the scrotum. Collections of fluid and abnormalities of the blood vessels may appear as masses and can be assessed by ultrasound. Masses both outside and within the testicles may be benign or malignant and should be evaluated as soon as they are detected.

Venous with PPG

Ultrasound waves are high frequency sound waves that can render a visible image of solid structures due to their differences in tissue density and can determine blood flow using Doppler technology that reflects waves back from things in motion, such as red blood cells. This makes it ideal for non-invasive investigation into blood vessels, both arterial and venous.

Venous Ultrasound Diagnosis

A venous ultrasound test is painless, simple, and readily available. A transducer (ultrasound broadcaster and receiver) is placed on the area under surveillance and the reflected waves are computed digitally to construct an image. The venous ultrasound tests are important in that they offer many advantages.

Prevention of Venous Disease Using Ultrasound

Prevention of venous disease using ultrasound is based on two strategies:

1. Prevention of initial diseases by screening
2. Prevention of disease progression

Prevention of Initial Disease: Screening

Those at risk for venous disease such as venous stasis, venous insufficiency, and thrombosis and embolic potential can be identified via an in depth history and a thorough physical exam. As such, screening of patients at risk for the initial onset of venous disease is indicated in the following groups:

- Diabetics
- Smokers
- Obese patients
- Immobilized patients
- Patients with a family history of coagulation conditions
- Patients with a history of trauma to the extremities

Arterial with ABI

The ankle-brachial index test is a quick, noninvasive way to check for Peripheral Artery Disease (PAD). The disease occurs when narrowed arteries reduce the blood flow to your limbs. PAD can cause leg pain when walking and increases the risk of heart attack and stroke.

The ankle-brachial index test compares the blood pressure measured at your ankle with the blood pressure measured at your arm. A low ankle-brachial index number can indicate narrowing or blockage of the arteries in your legs.
