Computed tomography, pelvis; without contrast material
CPT4 code
Name of the Procedure:
Computed tomography (CT) of the pelvis, without contrast material.
Summary
A CT scan of the pelvis uses X-rays to create detailed images of the pelvic area. This procedure is done without using a contrast material that enhances image clarity.
Purpose
The primary purpose is to diagnose issues in the pelvic region, such as injuries, tumors, infections, or other abnormalities. The goal is to provide clear, detailed images for accurate diagnosis and treatment planning.
Indications
- Persistent pelvic pain
- Unexplained pelvic masses
- Suspected fractures
- Abnormalities detected in previous imaging studies
- Pre- and post-surgical evaluations
- Assessment of pelvic organs
Preparation
- No fasting required if no contrast is used.
- Inform your doctor of all medications you're taking.
- Remove any metal objects that might interfere with imaging.
- Possibly change into a hospital gown for the procedure.
Procedure Description
- You will lie down on a motorized table.
- The table slides into a large, doughnut-shaped CT scanner.
- The technologist may use pillows or straps to help you remain still.
- The scanner rotates around your pelvis, taking multiple X-ray images from different angles.
- A computer assembles these images into detailed cross-sectional views.
Technologies used include the CT scanner and associated computer systems. No anesthesia or sedation is usually required.
Duration
The procedure typically takes about 10 to 20 minutes.
Setting
The procedure is performed in the radiology department of a hospital or an outpatient imaging center.
Personnel
- Radiologic technologists operate the CT scanner.
- Radiologists review and interpret the scans.
Risks and Complications
- Exposure to a low level of radiation, which is generally considered safe.
- Rare risk of needing additional scans if images are unclear.
- Mild discomfort from lying still during the scan.
Benefits
- Provides detailed images for accurate diagnosis.
- Non-invasive and quick.
- Can identify issues not visible through other imaging methods.
Recovery
- No specific recovery period; patients can usually resume normal activities immediately.
- Follow-up appointment to discuss scan results.
Alternatives
- MRI (Magnetic Resonance Imaging): No radiation but more expensive; better for soft tissue detail.
- Ultrasound: No radiation but less detailed images.
- X-rays: Less detailed and limited to specific views.
Patient Experience
- You may feel discomfort from holding a still position or from the hard table.
- No pain during the actual scanning process.
- Post-procedure, no significant discomfort or downtime expected.
