2 Cardiac Workflow
1. Prepare the patient.
2. Attach ECG electrodes to the patient.
3. Acquire a scout scan.
4. Acquire a heart localizer scan (recommended, but optional).
5. Acquire a manual bolus timing scan, or utilize the SmartPrep feature in the next step.
6. Acquire a contrast enhanced cardiac scan.
7. Create new images from cardiac scan data.
8. Review reconstructed images.
2.1 Prepare the patient
Follow these steps to prepare the patient for the cardiac exam.
2.1.1 Exam prep instructions
Advise the patient of the following:
•
Fast for four hours prior to the exam.
•
No caffeine 12 hours prior to the exam.
•
No cardiovascular exercise prior to the exam.
•
Thoroughly explain all phases of the scan before you start the exam to keep the patient as
calm as possible.
Administration of Beta Blockers and/or Sublingual Nitroglycern Spray can be used according to
your site's policy.
Please refer to the Society of Cardiovascular CT Guidelines at www.scct.org for more patient
preparation information.
2.1.2 Consent forms
If a consent form is required, review the form with the patient and get a signature.
2.1.3 Breathing instructions
Diagnostic cardiac images are dependent on the patient's heart rate during the data acquisition;
a calm patient keeps the heart rate steady with a repeatable rhythm. Therefore, breathing
instructions are critical for a successful cardiac scan.
Follow these breathing instruction guidelines:
•
Deliver the same instructions for each series starting with the scout scan.
•
Program cardiac breathing instructions with AutoVoice to deliver consistent breathing
instructions.
