• Maintain a clean and organized work environment to promote patient comfort and safety.

7. Explain the principles of cross-sectional imaging techniques such as CT and MRI.

Cross-sectional imaging techniques provide detailed images of the body by capturing images at specific depths.

CT (Computed Tomography)

• Uses X-rays to create cross-sectional images of the body.
• Produces axial, sagittal, and coronal views.

MRI (Magnetic Resonance Imaging)

• Uses magnetic fields and radio waves to create cross-sectional images of the body.
• Produces images with high soft tissue contrast and can differentiate between different tissue types.

8. Describe the different types of contrast agents used in medical imaging and their applications.

Contrast agents are used to enhance the visibility of specific structures or tissues in medical imaging.

X-ray Contrast Agents

• Radiopaque agents (e.g., barium sulfate) – Used to opacify the gastrointestinal tract.
• Radiolucent agents (e.g., air) – Used to create negative contrast for visualizing structures like the lungs.

CT Contrast Agents

• Iodinated agents – Used to enhance blood vessels, organs, and tissues.

MRI Contrast Agents

• Gadolinium-based agents – Used to enhance blood flow and visualize soft tissues.

9. Explain the use of fluoroscopy in medical imaging.

Fluoroscopy is a real-time imaging technique that allows for the visualization of moving structures.

• Uses X-rays to produce a continuous stream of images.
• Applications: Upper GI series, barium enemas, fluoroscopic-guided procedures (e.g., biopsies).

10. Discuss the importance of continuing education and professional development in Radiological Technology.

Continuing education is crucial for Radiological Technicians to stay up-to-date with advancements in technology, safety standards, and patient care best practices.
