Brief Summary:
The aim of the study is to determine the diagnostic accuracy of 99mTc ThromboView® SPECT imaging for the detection of acute pulmonary embolism (PE) in patients for whom there is a moderate to high clinical suspicion for PE.

Intervention Details:
  • Other: ThromboView
    Radiopharmaceutical, single dose, of the diagnosis of venous thromboembolism

Primary Outcome Measures :
  1. Provide estimates of the sensitivity of 99mTc ThromboView® in subjects with confirmed PE, as determined by computed tomographic pulmonary angiography (CTPA) and the specificity of 99mTc ThromboView® in subjects with PE excluded by CTPA [ Time Frame: June 2008 ]

  2. Moderate to high pre-test probability of acute pulmonary embolism.
  3. Positive D-dimer.
  4. Onset of PE symptoms occurring within the last seven days.
  5. Aged 18 years or older.
  6. Women of childbearing potential must have a negative serum pregnancy test (β-hCG) result at the time of enrollment into the study. Both male and female participants must agree to use effective contraception for the first 30 days after administration of 99mTc ThromboView®.

Exclusion Criteria:

  7. Previous participation in the current study.
  8. Current enrollment in a clinical trial involving any other investigational agent.
  9. Subject is unsuitable for SPECT scanning at the study Investigator's discretion (e.g. residual detectable radioactivity within the lungs due to prior imaging studies or treatment, preceding planned administration of 99mTc ThromboView®).
  10. Inability to perform CTPA or 99mTc ThromboView imaging, for any reason.
  11. Renal dysfunction: calculated creatinine clearance < 30 mL/min.
  12. Hepatic dysfunction: serum transaminases ≥ 3 x upper limit of normal range.
  13. Hepatic dysfunction: subject has history of chronic or currently active liver disease.
  14. Current pregnancy or lactation or conception intended within three months of enrollment.
  15. Subject is unsuitable for the study at the study Investigator's discretion. -
