Abstract: Objective To explore the diagnostic value of pulmonary perfusion SPECT/CT for patients with lower-limb deep-vein thrombosis (DVT) who may have pulmonary embolism (PE) with different Wells scores. Methods The study included DVT patients (n=210) with suspected PE. According to the Wells scores recommended by the 2008 European Pulmonary Embolism Diagnosis Guideline, the patients were divided into the high risk group (score ≥ 7, n=89), moderate risk group (2≤ score <7, n=64) and low risk group (score < 2, n=57). The patients' pulmonary perfusion SPECT/CT images were retrospectively analyzed. The positive rates of the three groups were calculated. The data were analyzed with chi-square(χ2)test. Results The positive rate of the high, moderate and low risk group was 70.8% (63/89), 29.7% (19/64) and 10.5% (6/57), respectively. There were statistical differences among the groups (χ2 = 57.47, P<0.05). Conclusion When DVT patients suspected of PE are diagnosed to have high risk or moderate risk by Wells scores, pulmonary perfusion SPECT/CT imaging should be recommended to confirm whether pulmonary embolism exists.
