Time Trend Analysis of PE Diagnosis With SPECT V/Q: a Single Institution Observational Study

Time Trend Analysis of Pulmonary Embolism Diagnosis With SPECT V/Q: a Single Institution Observational Study From 2011 to 2016

Following the implementation of SPECT V/Q imaging for PE diagnosis, the investigators previously conducted an observational study over the period 2011-2013 that showed the safety of a diagnostic management based on SPECT V/Q to rule out PE. However, PE prevalence was high (28%), which may seem a bit high as compared with other recent studies. The hypothesis was that the use of SPECT V/Q may be responsible for an overdiagnosis of PE, especially at the implementation phase of the test. The aim of this study was to perform a time trend analysis of the evolution over the years of PE diagnosis with SPECT V/Q.

Inclusion Criteria:

• Patients who underwent a SPECT V/Q scan performed for a suspected acute PE in the Nuclear Medicine Department of Brest University Hospital from April 2011 to December 2016

Exclusion Criteria:

• Patient under legal or judicial protection
• Patient opposed to the use of his medical data for research.
