Pulmonary hemorrhage after TTLB is common but rarely requires intervention. An enlarged mPAD at CT may not be a risk factor for higher-grade hemorrhage.

Summary Medical 3D printing is emerging as a clinically relevant imaging tool in directing preoperative and intraoperative planning in many surgical specialties and will therefore likely lead to interdisciplinary collaboration between engineers, radiologists, and surgeons. Data from standard imaging modalities such as CT, MRI, echocardiography and rotational angiography can be used to fabricate life-sized models of human anatomy and pathology, as well as patient-specific implants and surgical guides. Cardiovascular 3D printed models can improve diagnosis and allow for advanced pre-operative planning. The majority of applications reported involve congenital heart diseases, valvular and great vessels pathologies. Printed models are suitable for planning both surgical and minimally invasive procedures. Added value has been reported toward improving outcomes, minimizing peri-operative risk, and developing new procedures such as transcatheter mitral valve replacements. Similarly, thoracic surgeons are using 3D printing to assess invasion of vital structures by tumors and to assist in diagnosis and treatment of upper and lower airway diseases. Anatomic models enable surgeons to assimilate information more quickly than image review, choose the optimal surgical approach, and achieve surgery in a shorter time. Patient-specific 3D-printed implants are beginning to appear and may have significant impact on cosmetic and life-saving procedures in the future. In summary, cardiothoracic 3D printing is rapidly evolving and may be a potential game-changer for surgeons. The imager who is equipped with the tools to apply this new imaging science to cardiothoracic care is thus ideally positioned to innovate in this new emerging imaging modality.

Serial chest radiography sensitivity for detection of novel 2019 coronavirus infection approaches chest CT, suggesting utility of chest radiography as an adjunctive diagnostic tool for COVID-19 patients. ABBREVIATIONS AUC (area under the curve), ROC (receiver operating characteristic curve), COVID-19 (novel coronavirus 2019 infection), COVID-19+ (positive for novel coronavirus 2019 infection), COVID-19-(negative for novel coronavirus 2019 infection), GGO (ground-glass opacity), DA (diffuse airspace opacity), IA (interstitial and airspace opacities), FN (false negative)
