FIGURE 1 The uFPA concentration and V/Q scan results in 29 patients with suspected PE. The filled circles indicate patients with PE and the open circles indicate the patients in whom PE was excluded. The dotted line indicates a threshold level of 9.8 ng/ml. Patients are grouped into vertical columns in accordance with V/Q scan result (HP = “high probability of PE”; MP = “moderate probability of PE”; LP = “low probability of PE”; and NL = normal perfusion part of V/Q lung scan).
