Liver and spleen imaging; with vascular flow
CPT4 code
Name of the Procedure:
Liver and Spleen Imaging; Vascular Flow (Technetium-99m Sulfur Colloid Scan, Hepatosplenic Scintigraphy)
Summary
A liver and spleen imaging procedure with vascular flow is a non-invasive diagnostic test that utilizes a small amount of radioactive material to visualize the liver and spleen. This test helps assess the size, shape, and function of these organs, as well as the blood flow within them.
Purpose
The procedure is used to diagnose and evaluate medical conditions such as liver disease, spleen disorders, and abnormal blood flow in these organs. The goal is to identify possible abnormalities, help in the staging of certain diseases, and guide further treatment planning.
Indications
- Chronic liver disease or cirrhosis
- Unexplained enlargement of the liver or spleen
- Detection of tumors or cysts
- Assessment of trauma to the liver or spleen
- Monitoring the effects of treatment for liver or spleen conditions
Preparation
- Patients may be required to fast for a few hours before the procedure.
- Relevant medical history, including allergies and current medications, should be discussed with the healthcare provider.
- No specific diagnostic tests are typically required beforehand.
Procedure Description
- The patient receives an intravenous (IV) injection of a radioactive tracer, typically technetium-99m sulfur colloid.
- The patient lies on a scanning table, and a gamma camera captures images of the liver and spleen.
- Images are taken from multiple angles to provide a detailed view.
- In some cases, a vascular flow study may be included, involving additional images to assess the blood flow.
Tools Used:
- Gamma camera
- IV for radioactive tracer administration
Anesthesia/Sedation:
- None required
Duration
The entire procedure usually takes about 1 to 2 hours.
Setting
The procedure is performed in a hospital's nuclear medicine department or an outpatient imaging center.
Personnel
- Nuclear medicine technologist
- Radiologist or nuclear medicine physician
Risks and Complications
- Allergic reactions to the radioactive tracer (rare)
- Slight risk of radiation exposure
- Bruising or discomfort at the injection site
Benefits
- Non-invasive and relatively quick
- Provides detailed images of liver and spleen function and structure
- Helps in early diagnosis and effective management of liver and spleen conditions
Recovery
- Most patients can resume normal activities immediately after the procedure.
- Drink plenty of fluids to help flush the radioactive material from the body.
- Follow-up appointments may be scheduled to discuss results with the healthcare provider.
Alternatives
- CT scan or MRI for detailed imaging without radiation exposure.
- Ultrasound for initial evaluation of liver and spleen size and structure.
- Blood tests to assess liver function.
Patient Experience
During the procedure, the patient may feel a slight prick from the IV insertion. The injection of the radioactive tracer is typically painless. Lying still during the imaging can be slightly uncomfortable, but most patients tolerate it well. After the procedure, normal activities can be resumed, with minimal to no pain or discomfort.
