select each item in the left column and its match in the right column.
digital x - ray
safe three - dimensional imaging of soft internal anatomy
ct imaging
inexpensive three - dimensional imaging of hard internal anatomy
mri
inexpensive two - dimensional imaging of hard internal anatomy
ultrasound
inexpensive portable imaging of soft internal anatomy

Explanation:

• Digital X-ray: Uses ionizing radiation for 2D imaging of hard tissues (bones) and is relatively low-cost.
• CT imaging: Combines X-rays to create 3D images, effective for hard internal anatomy, and is more affordable than MRI.
• MRI: Uses magnetic fields for safe 3D imaging of soft tissues (e.g., brain, organs) without radiation.
• Ultrasound: Uses sound waves, is portable, inexpensive, and ideal for soft tissue imaging (e.g., fetus, organs).

Answer:

Digital X-ray: Inexpensive two-dimensional imaging of hard internal anatomy
CT imaging: Inexpensive three-dimensional imaging of hard internal anatomy
MRI: Safe three-dimensional imaging of soft internal anatomy
Ultrasound: Inexpensive portable imaging of soft internal anatomy
