Ventilation/perfusion (V/Q) scans are valuable for diagnosing pulmonary embolism (PE). For patients with intermediate or low V/Q scan likelihoods, further investigation or clinical correlation is crucial, especially if chest x-rays are abnormal.

Area of Science:

  • Radiology
  • Nuclear Medicine
  • Diagnostic Imaging

Background:

  • Pulmonary embolism (PE) diagnosis relies on various imaging modalities.
  • Ventilation/perfusion (V/Q) scintigraphy is a key tool in evaluating suspected PE.
  • Interpreting V/Q scan results requires careful consideration of likelihood ratios and clinical context.

Purpose of the Study:

  • To assess the diagnostic utility of V/Q imaging in suspected pulmonary embolism.
  • To determine optimal imaging strategies based on V/Q scan likelihood ratios and patient characteristics.
  • To evaluate the role of CT angiography as an alternative in specific patient subgroups.

Main Methods:

  • Retrospective analysis of V/Q scan results in patients with suspected PE.
  • Categorization of V/Q scans into normal, low, intermediate, and high likelihood ratios.

  • Comparison of diagnostic yield between V/Q scintigraphy and CT angiography in patients with parenchymal chest x-ray abnormalities.

    • Main Results:

    • Normal V/Q scans effectively exclude PE.
    • High likelihood V/Q scans are diagnostic for PE, but uncommon.
    • Intermediate and low likelihood V/Q scans necessitate further clinical evaluation or alternative imaging.
    • CT angiography may be preferred over V/Q scintigraphy for patients with intermediate likelihood and abnormal chest x-rays.

    Conclusions:

    • V/Q imaging is a useful diagnostic tool for PE, particularly for excluding the diagnosis.
    • A nuanced approach is required for interpreting intermediate and low likelihood V/Q scans.
    • CT angiography offers an alternative strategy for specific patient populations to enhance diagnostic utility.
