Computed tomography, abdomen; without contrast material
CPT4 code
Name of the Procedure:
Computed Tomography (CT) of the Abdomen; without Contrast Material
Summary
A CT scan of the abdomen without contrast material is an imaging procedure used to get detailed pictures of the abdominal organs and structures. It uses X-ray technology to create cross-sectional images.
Purpose
A CT scan of the abdomen helps diagnose conditions like infections, kidney stones, and liver diseases. It is also used to evaluate the extent of trauma or monitor an ongoing condition. The goal is to identify and assess abnormalities in the abdominal region.
Indications
- Persistent abdominal pain
- Unexplained weight loss
- Abdominal infections
- Kidney stones
- Liver or pancreatic abnormalities
- Trauma to the abdominal area
- Follow-up on previously identified conditions
Preparation
- No need for fasting or changes in medication unless otherwise directed by your doctor
- Wear comfortable, loose-fitting clothing
- Remove any metal objects, such as jewelry, as they can interfere with the imaging
- Inform your doctor if you are pregnant
Procedure Description
- The patient will lie on a motorized table that slides into the CT scanner.
- Straps and pillows may help maintain the correct position.
- The scanner will take a series of X-ray images from different angles as the table moves.
- The computer processes these images to generate detailed cross-sectional images of the abdomen.
- The technologist monitors the procedure from an adjacent room, where they can communicate with the patient.
Duration
The procedure typically takes about 10-30 minutes.
Setting
The procedure is usually performed in a radiology department at a hospital, outpatient clinic, or specialized imaging center.
Personnel
- Radiologist
- Radiologic Technologist
- Sometimes a nurse or technician for patient assistance
Risks and Complications
- Exposure to a small amount of radiation
- Rare allergic reactions, although contrast material is not used in this specific procedure
- Risk of missing certain conditions that only contrast material could highlight
Benefits
- Provides detailed images for accurate diagnosis
- Non-invasive and generally quick
- Helps in making informed decisions regarding further treatment
Recovery
- Generally, no recovery time is needed; patients can usually return to their normal activities immediately
- Follow any specific instructions provided by your healthcare provider
Alternatives
- Ultrasound: No radiation but might not be as detailed
- MRI: No radiation but can be more expensive and time-consuming
- X-ray: Limited details compared to CT
Patient Experience
Patients may feel a bit uncomfortable lying still during the procedure. There is no pain, and communication with the technologist is maintained throughout to ensure comfort and address any concerns.
