During the 3 years were examined 258 patients with acute exacerbation of COPD (186 man and 72 females).
Pulmonary embolism was found in 46 patients (17,8%).
The examinations were produced on multislice CT Light Speed VCT-64 General Electric and Aquillion-320 Toshiba.
Patients received 80-150 mL of contrast material (iohexol,
iodixanol,
ioversol) an injection rate of 3,5-4,0 ml/sec.
The US-doppler scan,
perfusion scintigraphy,
Ehocardiography and D-dimer were fulfilled also.
