Services - Dual Source CT
A computed tomography (CT) scanner explores almost every structure inside the body in a non-invasive way. A dual-source CT scanner uses two X-ray sources for high-definition images with unprecedented speed, exposing patients to less radiation.
- If your study requires the use of intravenous (IV) contrast:
- Your last meal should be no less than four hours before the study.
- A recent creatinine level of no more than six weeks is required for patients with one of the following: age 60 or older, hypertension, diabetes, or existing renal condition.
- The American College of Radiology (ACR) protocol requires a pre-medication regime for patients with a history of allergies to any IV contrast.
- A good hydration regime the day before the study as well as the day of the contrast media injection is highly recommended.
- Patients with compromised renal function usually do not inject iodine-based contrast unless a dialysis session is planned to avoid problems related to intravascular volume.
- Diabetic patients taking Metformin with GFR under 30 or with a known acute renal injury who will undergo a CT scan with intravenous contrast: Metformin should be stopped at the time of the CT and subsequently for 48 hours. After the referring physician or nephrologist verifies that renal function is normal, Metformin may be reinstituted under their supervision. Source: ACR Manual on Contrast Media, Version 10.3, 2017
