Magnetic resonance imaging vs. computed tomography: advantages and disadvantages

Area of Science:

• Radiology and Medical Imaging
• Neurology

Background:

• Magnetic resonance imaging (MRI) and computed tomography (CT) are key diagnostic imaging modalities.
• Demyelinating diseases and traumatic injuries require accurate detection of central nervous system lesions.

Purpose of the Study:

• To compare the sensitivity of MRI and CT in detecting parenchymal lesions of the brain and spinal cord.
• To define the optimal roles for MRI and CT in neurological imaging.

Main Methods:

• Comparative analysis of imaging findings from MRI and CT scans.
• Review of clinical indications for head and spine imaging.

Main Results:

• MRI demonstrates higher sensitivity than CT for detecting parenchymal lesions in the brain and spinal cord.
• CT excels in visualizing bony abnormalities, intracranial hemorrhage, and spinal trauma.

Conclusions:

• MRI is the preferred screening examination for suspected demyelinating diseases.
• CT remains the primary choice for evaluating trauma, bony abnormalities, and suspected disc herniation, particularly in uncooperative patients.
