Difference in interpretation of computed tomography pulmonary angiography diagnosis of subsegmental thrombosis in patients with suspected pulmonary embolism

Risk profile and clinical outcome of symptomatic subsegmental acute pulmonary embolism

“…It has recently been demonstrated that significant differences in the interpretation of SSPE among radiologists could occur. 20 Although all CTPAs were assessed according to a prespecified protocol, it cannot be ruled out that some of our patients were misclassified as having SSPE; this, however, reflects the diagnostic process of SSPE in daily clinical practice. Second, our definition used for SSPE included both single and multiple SSPE.…”

Contrast enhanced pulmonary magnetic resonance angiography for pulmonary embolism: Building a successful program

“…Pena et al (43) and Donato et al (44), however, observed that patients with untreated isolated SSPE had no adverse events. It is likely that an individual patient's risk of a life threatening thromboembolic event is more closely related to the clot burden in the deep venous system, rather than the size of the initial PE.…”

Overdiagnosis of Pulmonary Embolism by Pulmonary CT Angiography

“…Despite this, however, reported interobserver agreement varies widely, especially in the diagnosis of subsegmental PE [12]. Wide variations in concordance between general and subspecialist radiologists have been reported (89-100%) [13,14], as well as between residents, fellows, and attending radiologists (87-93%) [15][16][17]. Although pulmonary CTA examinations are frequently interpreted by general radiologists in most centers, limited data exist on the interobserver agreement between general and subspecialist chest radiologists.…”
