Interpretation of EEG, CT, and MRI Reports

Recognizing Common Artifacts in EEG Readings

Electroencephalography (EEG) is a vital tool in diagnosing neurological conditions. However, it is crucial to recognize and differentiate artifacts from genuine brain activity to avoid misinterpretation.

Common EEG Artifacts

• Electrode Artifacts: Poor electrode placement or loose contacts can result in abnormal readings.
• Physiological Artifacts: Signals from muscle movements, eye blinks, or cardiac activity may interfere with EEG recordings.
• Environmental Artifacts: External sources such as electrical interference from medical equipment can distort EEG results.

Methods to Reduce Artifacts

Minimizing artifacts involves proper electrode placement, patient preparation, and signal filtering techniques. Using artifact detection algorithms can also improve accuracy in EEG interpretations.

CT and MRI Correlation with EEG

Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) provide structural insights that complement EEG readings, especially in detecting abnormalities like lesions, tumors, or vascular anomalies.

Conclusion

Understanding common EEG artifacts is essential for accurate diagnosis. Correlating findings with imaging modalities such as CT and MRI ensures comprehensive neurological assessments.
