Bone Density

A bone density test determines if a patient has osteoporosis, a disease that causes bones to become more fragile and more likely to break. In the past, doctors could only detect osteoporosis after a patient broke a bone. By that time, however, your bones could be quite weak. A bone density test makes it possible to know your risk of breaking bones before the fact.

Cardiac Imaging: Echo and Stress Echo

Stress Echo

Stress Echocardiography is a procedure that determines how well your heart and blood vessels are working. During a stress echocardiography, you'll exercise on a treadmill or stationary bike while your doctor monitors your blood pressure and heart rhythm.

Preparation For Your Exam

Patients will be asked to not eat or drink anything 4 hours before the exam. We ask that patients refrain from smoking for 8 hours before the exam.


Echo Doppler is a cardiac ultrasound, which shows how the heartbeats and pumps blood. The Doppler analyzes the direction and velocity of the blood that flows through the heart. Cardiac ultrasound is not harmful in any way. This test tells the doctor how large the heart is, how well it is contracting, and how the valves are functioning.

Medical Diagnostic Services

CT Scan

Computerized tomography (CT scan) — also called CT — combines a series of images taken from different angles around your body and uses computer processing to create cross-sectional images (slices) of the bones, blood vessels, and soft tissues inside your body. A CT image provides more detailed information than a plain x-ray.

A CT scan visualizes nearly all parts of the body.

Preparations For All Patients

  • If patients are over 60 years old, or a diabetic patient and will be receiving an iodine injections, we MUST have a recent BUN/Creatinine level from the patient's physician’s office drawn within the past three months
  • Allergy preparation for iodine allergy (Seafood/Shellfish Allergy)
  • Consult your physician
  • Take 40 mg tablet of prednisone at bedtime the evening before your exam
  • Take 40 mg tablet of prednisone and 50 mg diphenhydramine (Benadryl) 2 hours prior to your appointment
  • You must have someone drive you home to and from the exam

Preparation For Diabetic Patients

Do not take any form of metformin the morning of your test (this includes Glucophage, Glucovance, Glumetza, Metaglip, Prandimet, Janumet, Avandamet, Fortamet, Riomet, etc.).

Patients may resume metformin 2 days (48 hours) after the exam. Experienced any renal issues in the past? Contact your physician.

Mammogram With 3D Technology

Mammography is an X-ray imaging of your breasts designed to detect tumors and other abnormalities. Mammography is used either for screening or for diagnostic purposes in evaluating a breast lump. 3D mammography is the newest technology available for mammograms. A 3D scan takes multiple images of your breast and allows the radiologist to detect smaller cancers.

Screening mammography is used to detect breast changes in women who have no signs, symptoms, or observable breast abnormalities. The goal is to detect cancer before clinical signs are noticeable. A screening mammogram consists of two mammogram images of each breast taken from different angles. During a mammogram, your breasts are compressed between two firm surfaces to spread out the breast tissue. Then, an X-ray captures black-and-white images of your breasts that a doctor uses to detect changes and cancer.

Nerve Testing

A nerve conduction study, also known as an EMG, uses surface electrodes — electrodes taped to the skin — to measure the speed and strength of signals traveling between two or more points. Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). An EMG uses tiny devices called electrodes to transmit or detect electrical signals. EMG results can reveal nerve dysfunction, muscle dysfunction, or problems with nerve-to-muscle signal transmission. After the EMG, patients may experience some temporary discomfort. If it persists, contact your primary care doctor.

Preparing For Your Exam

Take a shower or bath shortly before your exam to remove oils from your skin. Do not apply lotions or creams before the exam.

Envision Medical Group Ultrasound


  • Breast Ultrasound
  • Musculoskeletal Ultrasound
  • Vascular Doppler
  • Pelvic Ultrasound

An ultrasound is an imaging method that uses high-frequency sound waves to produce images of structures within your body. The images can provide valuable information for diagnosing and treating a variety of diseases and conditions. Diagnostic ultrasound is a safe procedure that uses low-power sound waves. There are no direct risks from a diagnostic ultrasound exam.

Doppler/Vascular Ultrasound

  • Arterial Doppler
  • Venous Doppler
  • Renal Flow Doppler
  • Carotid Doppler
  • Aorta Duplex

Doppler ultrasound is a noninvasive test to measure your blood flow and blood pressure by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells. A regular ultrasound uses sound waves to produce images, but can’t show blood flow.

A Doppler ultrasound can estimates how fast blood flows by measuring the rate of change in its pitch (frequency).


An X-ray is a quick, painless test producing images of the structures inside of the body, i.e. the bones.

X-ray beams pass through the body, but they absorb different amounts of the material depending on its density. Dense materials, such as bone and metal, show up as white on X-rays. The air in your lungs shows up as black. Fat and muscle appear as varying shades of gray.

For some types of X-ray tests, we may use a contrast medium — such as iodine or barium — to provide greater detail on the X-ray images.

Cardiac Monitors and Holter Monitors

A cardiac monitor is a device used to record the electrical activity of your heart (ECG). This device is about the size of a pager. It records your heart rate and rhythm. Cardiac monitors are available when you need long-term monitoring of symptoms that occur less than daily. You are able to take the monitor home and wear it for a designated period of time. This device helps doctors see how your heart reacts dung your normal day to day activities.

Home Sleep Studies

A home sleep apnea test is as it sounds. It is a sleep test the patient can take to their own home to determine if they have sleep apnea. The patient comes into the office to pick up equipment for their home sleep test. The office demonstrates how to perform the test, including how to use the machine and equipment properly. The patient goes home and performs the test. The data obtained is stored on the equipment and uploaded by the office the following day.

Home sleep tests provide patients with a convenient way to get the test done. Additionally, it allows the collection of important information on how patients sleep.
