IMAGING OF PULMONARY THROMBOEMBOLIC DISEASE

Recent developments in fast computed tomography (CT) scanning and magn etic resonance (MR) imaging techniques have enabled accurate, noninvas ive diagnosis of both acute and chronic thromboembolism, This chapter reviews the radiographic, CT, and MR imaging features of these disease s; discusses current thinking regarding the roles of these modalities in the diagnosis of pulmonary thromboembolic disease; and suggests a d iagnostic algorithm for incorporating fast CT scanning into the evalua tion of patients with suspected acute pulmonary emboli.
