HeartFlow LogoImage of a CT machine

Starting in 2018, ZP has teamed up with HeartFlow to offer a noninvasive personalized cardiac test to diagnose Coronary Artery Disease (CAD). The combination of CT technology and the HeartFlow Analysis allows your doctor to easily detect blockages in your coronary arteries and lower your risk of heart attacks. ZP is one of the first radiological practices in the area to offer the HeartFlow Analysis.

Using results from your CT scan, HeartFlow creates a personalized, digital 3D model of your coronary arteries, and provides blood flow information. This information was previously only available through an invasive procedure. With trained specialists and powerful computer algorithms, the HeartFlow Analysis calculates how much coronary artery blockages limit your blood flow. Once the HeartFlow Analysis is complete, the results are sent to your physician.

Your doctor will order a Coronary CT scan to detect if blockages are present in the vessels supplying blood to your heart muscle. A Coronary CT scan creates detailed 3D images of the blood vessels in your heart. Patients who are at risk of having blockages in the arteries can benefit from a CT scan, such as those with a family history of heart disease. The Coronary CT scan is faster, less invasive and lower risk than an invasive catheterization.

Sometimes, the CT scan provides enough information to determine the next step in the patient’s treatment plan. Other times more information is needed.

If more information is needed after reviewing your CT scan results, you may be a candidate for the HeartFlow Analysis. Without requiring any additional appointments, this advanced technology helps identify which blockages are limiting blood flow to your heart.

First, the technologist ensures that you have no metal on your body and reviews your medical history with you. You are then asked to lie on the scanning table, moved into the center of the machine, and asked to stay as still as possible to ensure the clearest images.

Most exams last only a few minutes, depending on the body part. The CT scan is non-invasive, and the machine never touches your body. The technologist is available via intercom should the patient have any concerns during the exam.

You must remove all jewelry and any other metallic objects such as hearing aids, jeans with metal zippers, body piercings, and removable dental work. Wearing a sweatsuit with no metal may prevent you from having to change into a gown.

Additional prep CT with I.V. contrast

Have nothing to eat 1 hour prior to your exam time. You may drink clear liquids (example: water, ginger ale, apple juice). Keep hydrated before and after your exam.

If you have impaired kidney function, are diabetic, or are 70 years of age or older, we will perform an i-STAT creatinine level at the time of your exam to assess your kidney function. It is important to inform us if you are taking the medication hydroxyurea when making your appointment.

Additional prep CT with oral contrast

If you are receiving oral contrast, please pick up the contrast kit the day before your exam. If you are receiving Omnipaque oral contrast, refer to the Omnipaque oral contrast section below. If you are receiving Redi-CAT oral contrast, please ask your Zwanger-Pesiri representative for those specific instructions.

Omnipaque oral contrast prep for CT scan

Do not take if you have an iodine allergy.

Begin drinking the Omnipaque oral prep 1 hour and 40 minutes before your exam, preferably finishing 20 to 30 minutes before the exam time.

To prepare the contrast drink:

  1. Pour HALF the contents of the Ominpaque bottle into the 32 oz. cup that was given to you.
  2. Fill the cup with water up to approximately 1/2 inch from the top of the cup (approximately 30 oz).
  3. Stir well and drink.
  4. Discard the cup, contrast bottle and straw after use.

Coronary CT Angiography

A Coronary CTA is a radiological test that is used to create detailed three dimensional images of the blood vessels in your heart, coronary arteries, heart chambers, coronary arteries and pulmonary veins. Patients who are at risk of having blockages in the arteries can benefit from a CCTA scan, such as those with a family history of heart disease. A CCTA is faster, less invasive and lower risk than an invasive catheterization.

Cardiac Calcium Scoring

A calcium scoring is a non-invasive way to view your coronary arteries and it helps identify the location and extent of calcified plaque. Plaque can narrow arteries, reduce blood flow to the heart and increase the risk of a heart attack. A Calcium Scoring is usually performed during a CCTA exam.

Neurological CT

CT scans of the brain and spine can provide more detailed information about tissue and structures than standard X-rays of the head, and provide more information related to injuries and diseases of the brain and spine. CT scans are not used as often as MRI scans when looking at brain or spinal cord tumors, but they can be useful in some cases. CT scans show greater detail of the bone structures near the tumor.

Body CT

CT of the abdomen and pelvis is a diagnostic imaging test used to help detect diseases of the small bowel, colon, and other internal organs and is often used to determine the cause of unexplained pain. CT shows bones, organs, and soft tissues more clearly than standard X-rays. CT scans are often used to show a tumor’s shape, size, and location. They can even show the blood vessels that feed the tumor, without having to go through an invasive surgical procedure.

CT Enterography

CT enterography is a specialized imaging test that lets us see detailed pictures of your small intestine and other structures in the abdomen and pelvis. It can pinpoint inflammation, bleeding, and other problems. MR Enterography is often recommended for patients with Crohn's disease to determine its location, severity and unexpected complications, in order to guide effective treatment.

Musculoskeletal CT

CT provides unmatched detail for viewing disorders of the bones, joints, and soft tissues. It allows our musculoskeletal imaging experts to diagnose not only athletic injuries, but also a wide range of disorders.
