An audit of ventilation and perfusion SPECT reporting for the diagnosis of pulmonary embolism in a tertiary cardiothoracic centre

The aim of the study was to identify reporting patterns of ventilation and perfusion single‐photon emission computed tomography (V/Q SPECT) scans done in our department over 3 months in 2016. Factors impacting on reporting and patient groups that would most benefit from the addition of low‐dose computed tomography (CT) to V/Q SPECT were analysed. Among 178 patients, 173 (97.2%) had a definitive (positive/negative) report and 2.8% had an equivocal report. As the majority of the equivocal reports were seen in patients aged ≥70 years, we believe that addition of low‐dose CT with V/Q SPECT to this patient group will reduce the non‐diagnostic rate.
