Which imaging modality is preferred for diagnosing a herniated disc?Question 37Select one:a.Ultrasoundb.CT scanc.MRId.X-ray

Breakdown the Problem

1. Identify the condition that needs to be diagnosed: herniated disc.
2. Evaluate the imaging modalities provided: Ultrasound, CT scan, MRI, and X-ray.
3. Determine the most effective imaging technique for diagnosing the condition based on medical standards.

Relevant Concepts

1. Herniated Disc: This condition occurs when the soft inner gel of the disc bulges out through a tear in the tougher exterior. It can often require imaging for diagnosis.
2. Imaging Modalities:
   • Ultrasound: Typically not used for spinal imaging.
   • CT Scan: Useful for viewing bone injuries but less effective for soft tissue.
   • MRI: Excellent for soft tissue contrast, particularly for spinal discs and nerves.
   • X-ray: Good for bone structure but does not show soft tissue issues well.

Analysis and Detail

1. Ultrasound: Limited usefulness in diagnosing spinal issues, particularly herniated discs.
2. CT Scan: Can provide some information about the bony structure but does not visualize soft tissues or discs well.
3. MRI: The gold standard for diagnosing a herniated disc, as it provides detailed images of soft tissues, including the discs and nerve roots.
4. X-ray: Primarily used to assess bony alignment and fractures; it does not visualize soft tissue.

Verify and Summarize

The MRI is widely recognized for its capability to provide detailed images of the spine and its soft tissues, making it the preferred modality for diagnosing a herniated disc.

Final Answer

c. MRI
