MRI is better for ________; CT is better for ________

MRI is better for ________; CT is better for ________

• A. MRI: Bone; CT: Soft tissues
• B. MRI: Soft tissues; CT: Bone
• C. MRI: Blood vessels; CT: Nerves
• D. MRI: Organs; CT: Muscles

Answer: (B)

MRI excels at soft-tissue contrast because it uses the magnetic properties of hydrogen and different pulse sequences to distinguish tissues like brain structures, muscles, ligaments, and edema. This makes it the go-to choice when the goal is to evaluate soft tissues and their pathology. CT, by contrast, uses X-ray attenuation and provides very high spatial resolution for dense structures. Bone attenuates X-rays strongly, so cortical bone and fracture lines are depicted with great clarity and detail on CT, making it ideal for evaluating bone anatomy and injuries. Because bone signal on MRI is limited and cortex can appear dark, MRI isn’t the best for bone detail, while CT isn’t as good as MRI for soft-tissue differentiation. This is why the pairing is MRI for soft tissues and CT for bone.
