    12. Validation of full-field optical coherence tomography in distinguishing malignant and benign tissue in resected pancreatic cancer specimens

      Validation of full-field optical coherence tomography in distinguishing malignant and benign tissue in resected pancreatic cancer specimens
      Background Pancreatic cancer is the fourth leading cause of cancer-related mortality in the United States. The minority of patients can undergo curative-intended surgical therapy due to progressive disease stage at time of diagnosis. Nonetheless, tumor involvement of surgical margins is seen in up to 70% of resections, being a strong negative prognostic factor. Real-time intraoperative imaging modalities may aid surgeons to obtain tumor-free resection margins. Full-field optical coherence tomography (FF-OCT ...

    13. Is quantitative coronary angiography reliable in assessing the late lumen loss of the everolimus eluting bioresorbable polylactide scaffold in comparison with the cobalt chromium metallic stent?

      Is quantitative coronary angiography reliable in assessing the late lumen loss of the everolimus eluting bioresorbable polylactide scaffold in comparison with the cobalt chromium metallic stent?
      Aims: Immediately after stent/scaffold implantation, quantitative coronary angiography (QCA) with respect to optical coherence tomography (OCT) more severely underestimates the lumen diameter (LD) in Absorb than in XIENCE. This OCT-QCA discrepancy has not been evaluated at long-term follow-up. The present study aimed to assess the accuracy of QCA with reference to OCT in Absorb as compared to XIENCE.
