SPECT ventilation perfusion scanning with the addition of low‐dose CT for the investigation of suspected pulmonary embolism

Single‐photon emission computed tomography ( SPECT ) ventilation perfusion ( V/Q ) scanning with low‐dose computed tomography ( LDCT ) is an emerging imaging technique for investigation of suspected pulmonary embolism ( PE ). We aimed to estimate diagnostic utility of the combined technique using results from all patients referred in 2009 compared with final diagnosis and 6‐month follow‐up status. PE was diagnosed in 28 of 106 patients (26%),...
