Published ahead-of-print in JTI
Published ahead-of-print is a systematic review entitled “Diagnostic strategies incorporating computed tomography angiography for pulmonary embolism: a systematic review of cost-effective analyses” by Raymakers AJN and colleagues from the University of British Columbia. The authors performed a comprehensive search of mulitple databases for studies that included pulmonary embolism diagnosis and economic evaluation. Thirteen studies were identified and included in the systematic review. These studies, with the exception of one that focused exclusively on pregnant women, all used clinical risk assessment as part of the diagnostic algorithm, typically D-dimer or. The authors of this systematic review conclude that cost-effective analysis is useful for assessing potential algorithms for the diagnosis of pulmonary embolism. Furthermore, the authors suggest that future cost-effective analyses should include magnetic resonance angiography and potential for establishing alternative diagnoses in the diagnostic algorithm.
Also published ahead-of-print is the latest installment in the Signs in Cardiopulmonary Imaging series entitled “Ischemic Late Gadolinium Enhancement” by Chou and colleagues. An explanation of this sign and its differential diagnosis are provided.
Finally, Krausz and colleagues performed a retrospective study, “Retained fibrin sheaths: chest computed tomography findings and clinical associations”, on 147 adult patients who underwent chest CT after removal of a central venous catheter. The authors reported 20 (13.6%) retained fibrin sheaths of which 9 (45%) were calcified. Women and patients with venous occlusion were more likely to have retained fibrin sheath (p=0.0001 and p=0.0003, respectively).
