Summary
The diagnosis of pulmonary embolism may be difficult, because no reliable noninvasive imaging method is available. An accurate, noninvasive diagnostic modality is highly desirable. The purpose of this study was to evaluate the accuracy of magnetic resonance (MR) angiography in the noninvasive diagnosis of pulmonary embolism. Eighteen patients in whom the presence of pulmonary emboli was suspected underwent both conventional pulmonary angiography and MR angiography. The sensitivity and specificity of MR angiography to the level of lobar arteries were 100% and 85%, respectively, and to the level of segmental arteries, 94% and 78%, respectively. A single sectional image of MR angiography can depict thromboemboli in the proximal portion of the pulmonary arteries more definitively than conventional pulmonary angiography or a maximum-intensity-pixel projection image of MR angiography. MR angiography can reliably depict pulmonary thromboemboli down to the segmental level.
