Risks and Benefits of Contrast Media
Risks and Benefits of Contrast Media
Contrast media can be risky, so weighing the potential benefits against the risks is crucial before using it.
Informed Consent for Contrast Media
Informed Consent for Contrast Media
In emergency situations, contrast media may be used without explicit informed consent because the benefits outweigh the immediate risks.
Low-Osmolality Contrast Media
Low-Osmolality Contrast Media
Low-osmolality contrast media has a lower concentration of dissolved particles than blood, reducing the likelihood of side effects.

Study Notes
Contrast-Assisted Examinations
- A preliminary consideration for both referring physicians and radiologists is the potential risks and benefits of contrast-assisted examinations.
Informed Consent
- Intravenous injection of contrast media may be exempted from informed consent requirements in certain situations, such as emergency cases or when the risk is minimal.
- The decision on whether intravenous injection of contrast media requires informed consent is influenced by factors such as the patient's medical history, the type of contrast media, and the potential risks.
Radiographic Iodinated Contrast Media
- The term 'low-osmolality' refers to contrast media with a lower osmolality than blood, which reduces the risk of adverse reactions.
Clinical Indication
- A valid clinical indication is essential for each contrast medium administration to ensure that the benefits outweigh the risks.
Side Effects and Pre-Existing Conditions
- When evaluating the likelihood of side effects from contrast-assisted examinations, radiologists should consider not only pre-existing conditions but also the patient's medical history, allergies, and medications.
Contrast Media Reactions
- Radiologists should be prepared for contrast media reactions, which can be severe and life-threatening.
- It is crucial to have an availability of appropriately trained personnel, equipment, and medications for contrast media reactions.
- Radiologists should be familiar with the emergency treatment of contrast media reactions to ensure prompt and effective management.
Quality Assurance and Quality Improvement
- An ongoing quality assurance and quality improvement program is recommended for radiologists and technologists to ensure that contrast media is used safely and effectively.
Approving and Performing Examinations
- A key element that should be in place prior to approving and performing examinations using contrast media is a valid clinical indication and a thorough evaluation of the patient's medical history and potential risks.
- Prior to approving and performing radiological examinations involving contrast media, radiologists should evaluate the patient's medical history, assess the potential risks and benefits, and ensure that the patient is informed and prepared for the examination.
