Abstract:
OBJECTIVETo compare the diagnostic value of (99)Tc(m)-MAA pulmonary perfusion imaging with that of pulmonary angiography for pulmonary involvement in Takayasu's arteritis.
METHODSTwenty-one patients (19 women, 2 men), with diagnosed Takayasu's arteritis and underwent both (99)Tc(m)-MAA pulmonary perfusion imaging and pulmonary angiography, were retrospectively analyzed.
RESULTSOut of the 21 patients, pulmonary angiography detected 11 patients with pulmonary artery involvement whereas 13 patients were revealed perfusion defects by pulmonary perfusion imaging. The agreement of diagnosis by pulmonary perfusion imaging with that by pulmonary angiography existed in 19 patients (90.5%, Kappa = 0.81, P < 0.0001). There were 331 pulmonary segments consistently diagnosed by pulmonary perfusion imaging and pulmonary angiography in 378 pulmonary segments (87.5%, Kappa = 0.74, P < 0.0001).
CONCLUSIONSPulmonary perfusion imaging is highly accorded with pulmonary angiography in detecting the pulmonary involvement in Takayasu's arteritis. Therefore, pulmonary perfusion imaging could be used as a non-invasive screening test for the pulmonary artery involvement in Takayasu's arteritis.
