Name of the Procedure:

Common Name: Low Osmolar Contrast Material Technical Term: Low Osmolar Contrast Agent, 300-399 mg/ml iodine concentration (HCPCS Code: Q9967)

Summary

This medical procedure involves the administration of a low osmolar contrast material, containing 300-399 mg/ml of iodine concentration, used in imaging studies to enhance visibility of bodily structures and improve diagnostic accuracy.

Purpose

The contrast material is primarily used in various imaging tests such as CT scans, angiography, and other radiological procedures to:

• Improve the clarity of images.
• Help in diagnosing and evaluating medical conditions like blood vessel diseases, gastrointestinal disorders, and tumors.

Indications

• Symptoms like unexplained pain, swelling, or abnormal blood test results warrant deeper diagnostic imaging.
• Conditions such as heart disease, blood vessel abnormalities, or gastrointestinal issues where enhanced imaging is required.
• Pre-surgical planning where detailed images of structures are necessary.

Preparation

• Patients might be instructed to fast for a few hours before the procedure.
• Certain medications may need adjustment or temporary discontinuation based on doctor’s instructions.
• Pre-procedure tests might include kidney function tests to ensure it’s safe to use contrast material.

Procedure Description

1. Patient is placed in the appropriate position for the imaging study.
2. An intravenous (IV) line is inserted to administer the contrast material.
3. The contrast agent is injected through the IV line.
4. Imaging scans are conducted, with the contrast material helping to highlight specific areas.
5. The IV is removed once the imaging is complete.

Tools and Technology:

• IV line and contrast material syringe.
• Imaging machine like a CT scanner.

Anesthesia or Sedation:

• Typically, no anesthesia required, but sedation might be used in some cases where the patient has anxiety or difficulty remaining still.

Duration

The administration of the contrast material takes a few minutes, while the entire imaging procedure may take anywhere from 15 minutes to an hour.

Setting

The procedure is performed in settings equipped with imaging facilities such as:

• Hospital radiology departments.
• Outpatient imaging centers.
• Surgical centers with advanced diagnostic capabilities.

Personnel

• Radiologist to interpret images.
• Radiologic technologist or nurse to administer the contrast and run the imaging equipment.
• Anesthesiologist if sedation is required.

Risks and Complications

Common Risks:

• Mild allergic reactions like itching or rash.
• Temporary warming sensation or metallic taste during injection.

Rare Risks:

• Severe allergic reactions (anaphylaxis).
• Kidney impairment, particularly in patients with pre-existing kidney issues.

Management:

• Immediate medical attention for severe allergic reactions.
• Hydration and monitoring for kidney function post-procedure.

Benefits

• Enhanced imaging detail leading to more accurate diagnosis.
• Non-invasive with relatively quick recovery.

Realization Time:

• Diagnostic insights are available almost immediately post-scan review by the radiologist.

Recovery

• Patients can usually resume normal activities shortly after the procedure.
• Increased fluid intake may be recommended to help flush out the contrast material.
• Follow-up appointments are generally based on imaging results and ongoing care needs.

Alternatives

• Non-contrast imaging studies (usually less detailed).

• Other imaging modalities like MRI or ultrasound.

  Pros and Cons:

• Non-contrast studies pose fewer risks but may be less informative.
• MRI doesn’t use iodine but may not be suitable for all patients due to claustrophobia or metal implants.

Patient Experience

• During the procedure: Mild discomfort from the IV insertion and brief warming sensation during contrast administration.
• After the procedure: Minimal to no pain, with potential for mild side-effects like headache or nausea, managed through hydration and rest.
