All forms should be completed in advance of your appointment. Please follow the link below to access the CT Safety Form required for your upcoming appointment. If you are having a cardiac CT (CT of your heart), please complete the Cardiac CT Safety Form.
If you are having a Cardiovascular CT (CT of the heart), please complete the CT Cardiovascular Form in addition to the general form.
Please notify our staff when scheduling and checking in for your appointment if any of the following apply to you:
Arrive at the time of your appointment. Weill Cornell Imaging at NewYork-Presbyterian is limiting the number of patients in our offices at any one time. Patients who arrive early may be asked to return at the time they are scheduled.
Unless needed for physical assistance or to translate for you, visitors are not allowed to accompany patients into our practices. One parent may accompany a child.
If you are having a Cardiac CTA (Computed Tomography Angiography of your heart), click here to review the exam preparations or follow the link below.
Wearing the right clothing may eliminate the need for you to change into a gown prior to your exam. Suggestions for appropriate clothing include:
Depending on the type of exam you are having, you may need to fast before your exam or adjust the use of certain medications.
All of our imaging practices have procedures in place to ensure the safety of our patients and staff. These include:
All patients and visitors are clinically screened upon arrival including a temperature check.
Patient verification is an important part of your safety and you will be asked to verify your identification and your exam several times during your appointment. Our check-in staff will review your completed registration forms with you.
For many exams you will not have to change into a gown unless you are wearing something that contains metal (see guidelines above). Some exams do require that you are in a gown. You will be asked to remove and place your electronic devices, wallet, credit cards, metro card, watch, jewelry, belt, hairpins, eyeglasses, hearing aid, or any removable dental pieces into the provided lockers.
Some CT scans require the use of an iodinated contrast material, also known as "x-ray dye” which is injected through an intravenous (IV) line. If contrast is required, a skilled nurse or technologist will start this IV line in the arm or hand prior to the examination. The IV will be removed immediately after the exam.
Some CT scans of the abdomen and pelvis require oral contrast. If you are given oral contrast as part of your exam you will have to wait approximately 1 hour after drinking the contrast until the contrast has made it to the part of your bowel that it needs to be.
Before you enter the CT scanning room, a technologist will review the safety questionnaire with you. We understand that this may seem redundant but your safety is our first priority. Once the technologist is assured that it is safe to proceed, he or she will escort you into the scanning room and onto the CT table.
A CT or CAT scan is a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices) of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, organs, and blood vessels. CT scans are more detailed than standard x-rays.
In standard x-rays, an invisible beam of energy is aimed directly at the body part being studied. A plate behind the body part captures the variations of the energy beam after it passes through skin, bone, muscle, and other tissue. While much information can be obtained from a regular x-ray, a lot of detail about internal organs and other structures is not available.
During CT scans, the x-ray beam moves in a circle around the body as oppose to a straight line during a general x-ray. This allows many different views of the same organ or structure, and provides much greater detail. The x-ray information is sent to a computer that interprets the x-ray data and displays it in 2-dimensional form on a monitor. Additional advanced technology and computer software makes three-dimensional (3-D) images possible.
CT scans may be done with or without contrast. "Contrast" refers to a substance taken by mouth or injected into an intravenous (IV) line that causes the particular organ or tissue under study to be seen more clearly. Contrast examinations may require you to fast for a certain period of time before the procedure. Your physician will notify you of this prior to the procedure.
You will need to let your physician know if you have ever had a reaction to any contrast dye or if you are allergic to iodine. If you have any medical conditions or recent illnesses, inform your physician. If you are pregnant or think you may be pregnant, you should notify your physician and not proceed with the CT scan unless absolutely necessary.
