Study Notes
Types of Exams and Radiation
- Ultrasound and MRI do not emit radiation during their procedures.
3D Imaging and Views
- A minimum of two views at 90-degree angles is required to reconstruct a 3D image.
- The most commonly used combination for 3D image reconstruction includes two orthogonal views, such as axial and coronal.
X-Ray Imaging Appearance
- Tissues with high density appear white on X-ray imaging; this includes bones and metals.
- Air appears black in X-ray imaging due to its low density.
- Soft tissues appear as varying degrees of grey depending on their density.
Radiation Risks
- Pregnant women and children are at the most risk for radiation effects due to their developing cells and tissues.
Iodinated Contrast Media Considerations
- The patient's kidney function should be assessed before using iodinated contrast media to prevent potential kidney damage.
- Allergic reactions are a potential concern when using iodinated contrast media, including symptoms like hives or anaphylactic reactions.
Newer Contrast Media
- Most newer contrast media are designed to be less likely to cause allergic reactions and are often non-ionic, which enhances patient safety and comfort.
