Name of the Procedure:

Low Osmolar Contrast Material Administration
Medical Term: Low osmolar contrast material, 200-299 mg/ml iodine concentration, per ml (HCPCS Q9966)

Summary

Low osmolar contrast material is a type of dye used during imaging tests such as CT scans or MRIs. It helps to create clearer images of the inside of the body, aiding in the diagnosis of various medical conditions. This particular preparation has an iodine concentration of 200-299 mg/ml.

Purpose

This contrast material is used to enhance the visibility of organs, blood vessels, and tissues during imaging exams. It helps in diagnosing issues like tumors, blockages, or other abnormalities.

Indications

• Detecting tumors or cancer
• Investigating blood vessel abnormalities like aneurysms
• Diagnosing infections or inflammation
• Evaluating organ function and detecting damage
• Assessing the structure of blood vessels and digestive organs

Preparation

• Patients may need to fast for a few hours before the exam.
• Certain medications might need to be adjusted as per physician guidelines.
• Pre-procedure screening may include blood tests to check kidney function.

Procedure Description

1. The patient is positioned under the imaging device.
2. An intravenous (IV) line is inserted to administer the contrast material.
3. The contrast material is injected through the IV line, which travels through the bloodstream.
4. As the contrast circulates, images are taken by the imaging device.

Tools and Equipment:

• IV supplies
• Imaging machines (CT scan or MRI)

Anesthesia or Sedation:

• Not typically required. Sedation may be used for anxious patients or children.

Duration

The actual injection of the contrast material takes only a few minutes, but the entire imaging procedure may last 30 minutes to an hour.

Setting

This procedure is conducted in a hospital, outpatient imaging center, or specialized diagnostic facility.

Personnel

• Radiologist
• Radiologic technologists
• Nurses or medical assistants

Risks and Complications

• Allergic reactions to the contrast material
• Kidney function impairment in susceptible individuals
• Discomfort or pain at the injection site
• Rare risks include severe allergic reactions or anaphylaxis

Benefits

• Enhanced and more accurate imaging results
• Better diagnostic capability leading to more effective treatment plans
• Immediate visual evidence of abnormalities

Recovery

• Patients can usually resume normal activities immediately after the procedure.
• Drinking plenty of water is advised to help flush out the contrast material.
• Follow-up appointments may be scheduled to review the imaging results.

Alternatives

• Non-contrast imaging exams: lack the enhanced visibility provided by contrast material
• Ultrasound: a non-invasive option without contrast but less detailed for certain conditions
• Non-iodine based contrast agents: an option for patients with iodine allergies

Patient Experience

During the injection, patients might feel a warm sensation or a metallic taste. Post-procedure, any discomfort is typically mild and temporary. Pain management measures include over-the-counter pain relievers if needed, although discomfort is rare.
