Diagnosis efficiency for pulmonary embolism using magnetic resonance imaging method: a meta-analysis

Area of Science:

• Radiology and Diagnostic Imaging
• Cardiovascular Diseases
• Pulmonary Medicine

Background:

• Pulmonary embolism (PE) is a frequent and potentially life-threatening condition often characterized by misdiagnosis.
• Accurate diagnostic tools are crucial for timely intervention and improved patient outcomes.

Purpose of the Study:

• To evaluate the diagnostic performance of magnetic resonance imaging (MRI) in assessing the resectability of pulmonary embolism (PE).
• To quantify the sensitivity and specificity of MRI for PE diagnosis through a meta-analysis.

Main Methods:

• A meta-analysis was conducted on five studies reporting sensitivity and specificity for MRI in PE diagnosis.
• Pooled sensitivity, specificity, likelihood ratios, and diagnostic odds ratio were calculated with 95% confidence intervals.
• Summary receiver operating characteristic (SROC) curve analysis was performed.

Main Results:

• The pooled sensitivity for MRI in PE diagnosis was 0.83 (95% CI: 0.78-0.88) with moderate heterogeneity (I²=62.8%).
• The pooled specificity was high at 0.99 (95% CI: 0.98-1.00) with no significant heterogeneity (I²=0.0%).
• The area under the SROC curve (AUC) was 0.9852, indicating excellent diagnostic accuracy.

Conclusions:

• Magnetic resonance imaging (MRI) exhibits high sensitivity and specificity for diagnosing pulmonary embolism (PE).
• MRI serves as a valuable and supportive tool in the clinical diagnosis of PE.
• The findings support the integration of MRI into diagnostic algorithms for PE.
