Magnetic resonance (MR) imaging effectively identifies thoracic disk herniation, comparable to CT myelography. However, precise localization can be challenging due to low signal intensity in some cases.

Area of Science:

  • Radiology
  • Neurosurgery
  • Spinal Imaging

Background:

  • Thoracic disk herniation is a rare condition.
  • Accurate diagnosis is crucial for effective treatment.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of magnetic resonance (MR) imaging for thoracic disk herniation.
  • To compare MR imaging findings with conventional methods like plain and computed tomography (CT) myelography and surgical confirmation.

Main Methods:

  • Retrospective analysis of MR images from patients with suspected thoracic disk herniation.
  • Independent interpretation of MR images.
  • Comparison with plain myelography, CT myelography, and surgical findings.

Main Results:

Related Experiment Videos

  • Sixteen cases of thoracic disk herniation were confirmed.
  • MR imaging, using sagittal T1 and T2 weighted, and axial T1 weighted sequences, demonstrated diagnostic equivalence to CT myelography.
  • In two cases, herniation was inferred from spinal cord mass effect due to low disk signal intensity.
  • Accurate level localization using body coil MR images was achieved in 6 of 13 patients.

Conclusions:

  • MR imaging is a valuable tool for diagnosing thoracic disk herniation.
  • CT myelography and MR imaging show comparable diagnostic performance.
  • Challenges in precise level localization may arise from low signal intensity of the herniated disk.
