Magnetic resonance. Principles and applications.

Area of Science:

• Radiology
• Medical Imaging
• Biochemistry

Background:

• Magnetic resonance (MR) is a noninvasive imaging modality offering multiplanar visualization and in vivo biochemical analysis.
• Currently, MR is most effectively applied to central nervous system (CNS) abnormalities, showing high sensitivity for intracranial pathology.

Purpose of the Study:

• To review the current applications and limitations of magnetic resonance imaging across various medical specialties.
• To identify areas where MR may replace or supplement existing imaging modalities and highlight future research directions.

Main Methods:

• Review of existing literature on magnetic resonance imaging applications.
• Comparative analysis of MR efficacy against other imaging modalities like CT and ultrasound in different anatomical regions.

Main Results:

• MR demonstrates high sensitivity for CNS and spinal conditions (e.g., Chiari malformation, tumors) and shows potential in mediastinal tumor staging and breast lesion evaluation.
• While promising for hepatic masses, cardiac conditions, and vascular imaging, MR requires improved specificity to supplant CT in abdominal and pelvic imaging.
• MR shows promise for diagnosing avascular necrosis and osteomyelitis, with in vivo MR spectroscopy offering unique metabolic insights.

Conclusions:

• Magnetic resonance imaging is a powerful tool, particularly for neurological and spinal evaluations, with expanding potential in other fields.
• Further research focusing on improving MR specificity and addressing technical limitations is crucial for its broader clinical adoption.
• In vivo MR spectroscopy represents a significant advancement, offering unprecedented metabolic information.
