    Area of Science:

    • Pulmonology
    • Radiology
    • Diagnostic Imaging

    Background:

    • Pulmonary embolism (PE) is a frequent and potentially life-threatening condition.
    • Accurate diagnosis of PE using noninvasive methods remains a clinical challenge.
    • Early and correct diagnosis is crucial for effective patient management.

    Purpose of the Study:

    • To discuss the diagnostic utility of ventilation-perfusion (V/Q) scans in suspected pulmonary embolism.
    • To review the roles of both standard and emerging imaging modalities for PE evaluation.
    • To provide an overview of current diagnostic strategies for pulmonary embolism.

    Main Methods:

    • Review of existing literature on diagnostic imaging for pulmonary embolism.
    • Discussion of ventilation-perfusion (V/Q) scintigraphy principles and interpretation.
    • Evaluation of the performance of various noninvasive imaging techniques.

    Main Results:

    • Ventilation-perfusion (V/Q) scans are a key tool in diagnosing pulmonary embolism.
    • The diagnostic accuracy of V/Q scans can be limited in certain patient populations.
    • Newer imaging modalities offer complementary or alternative diagnostic pathways.

    Conclusions:

    • Accurate diagnosis of pulmonary embolism requires careful consideration of clinical probability and imaging findings.
    • Ventilation-perfusion (V/Q) scanning remains an important, though not universally definitive, diagnostic test.
    • The integration of multiple imaging modalities enhances the diagnostic capability for pulmonary embolism.
