Neuroradiology 2

Question 1

Appreciate these points about CT scans:

Pros:

• Axial acquisition with 3D/multiplanar reconstruction
• Excellent bony details/spatial resolution
• Fast
• Compatible with emergency/ICU equipment

Cons:

• Poor soft tissue detail/contrast resolution
• Multiplanar/3D reconstruction but no direct multiplanar acquisition
• Radiation

Question 2

What are the pros and cons of MRI scans ?

Answer 2

Pros:

• Excellent contrast/soft tissue resolution
• Excellent depiction of anatomy
• Marrow and cord pathologies
• Multiplanar capability

Cons:

• Less bony detail
• Less spatial resolution
• Not compatible with pacemakers and many implants
• Not compatible with most ICU/emergency equipments
• Not as quick as CT; Patient cooperation required
