Assessment of Diffusion and Perfusion01:17

Assessment of Diffusion and Perfusion

Understanding and evaluating diffusion and perfusion is critical in assessing a patient's respiratory and circulatory health. These processes play key roles in maintaining the body's internal environment, ensuring that tissues receive adequate oxygen while waste products are efficiently removed.
The Role of Diffusion in Respiration
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this principle...
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,...
Ischemic Stroke l: Introduction01:15

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.

Summary

Diffusion-weighted MRI (DWI) shows promise for detecting spinal cord infarction, a condition often missed by conventional MRI. This technique identified restricted diffusion in all tested patients, suggesting its utility in early diagnosis.

Area of Science:

  • Neurology
  • Radiology
  • Medical Imaging

Background:

  • Spinal cord infarction presents with acute paralysis and sensory loss, but conventional MRI is often normal.
  • Diffusion-weighted imaging (DWI) is effective for acute stroke detection in the brain.
  • Preliminary evidence suggests DWI may aid in diagnosing spinal infarction.

Purpose of the Study:

  • To evaluate the utility of DWI in diagnosing acute spinal cord ischemia.
  • To compare DWI findings with conventional MRI in spinal cord infarction cases.

Main Methods:

  • Six patients with suspected acute spinal cord ischemia underwent DWI using navigated, interleaved, multishot echo planar imaging (IEPI).
  • Imaging findings were analyzed and compared with existing literature.

Main Results:

  • All patients exhibited restricted diffusion on isotropic DWI images, indicated by low ADC values.
  • These findings suggest acute ischemic changes within the spinal cord.

Conclusions:

  • DWI appears to be a useful and feasible technique for detecting spinal infarction.
  • Combined with conventional MRI, DWI enhances diagnostic capabilities for spinal cord ischemia.
  • Further studies with larger cohorts are warranted to confirm DWI's role.
