Magnetic Resonance Imaging01:24

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Summary
This summary is machine-generated.

Spinal cord decompression sickness (DCS) involves both arterial and venous infarction, not just venous. Early symptoms and multiple spinal cord lesions indicate a poorer outcome in DCS patients.

Area of Science:

  • Neurology
  • Radiology
  • Hyperbaric Medicine

Background:

  • Spinal cord decompression sickness (DCS) is a rare but serious condition.
  • DCS can lead to spinal cord infarction, impacting neurological function.
  • This study examines seven DCS cases managed at a local hyperbaric facility.

Observation:

  • MRI revealed patchy T2W changes across multiple spinal cord levels.
  • Grey matter involvement, typical of arterial infarction, was observed in most patients.
  • Initial neurological assessment used the Frankel grading scale.

Findings:

  • Contrary to common belief, DCS appears to involve arterial infarction patterns.
  • Multiple spinal cord level involvement (>6) correlated with poor outcomes.
  • Rapid symptom onset (within 30 minutes of surfacing) predicted less symptom resolution.

Implications:

  • DCS likely results from a combination of arterial and venous infarction.
  • Early neurological symptom onset and extensive spinal cord lesions are indicators of a worse prognosis.
  • Findings emphasize the need for timely and comprehensive treatment for spinal cord DCS.
