A CT scan (computed tomography) uses rotating X-ray beams and computer processing to create detailed cross-sectional images of the body, which can be reconstructed into 3D models. MRI Associates uses 64-slice systems — the newest multi-detector scanners can image the entire body, head to toe, in less than 30 seconds.

What is CT used for?
CT is fast and detailed, which makes it the right tool when speed matters or when bone and acute findings are the question.
- Rapid trauma evaluation of the brain, chest, and abdomen
- Vascular assessment with contrast enhancement
- Tumor and mass evaluation
- Kidney stones and acute abdominal pain
- Image-guided interventional procedures such as biopsies and drainage placement
What happens during a CT scan?
You lie on a table that advances through the scanner in small increments. Modern spiral scanners complete most scans in minutes, and you may be asked to hold your breath briefly so the images are not blurred.
How do I prepare?
Fasting for 4 to 6 hours may be required if contrast is used. Oral contrast — barium sulfate or Gastrografin, sometimes mixed with apple juice — may be given beforehand. Remove metal jewelry; a gown is provided if needed. Normal eating and activity may resume immediately after a CT scan.
What equipment is used?
- Philips Ingenuity Elite — Head-to-toe detail in seconds at low dose.
