We sought to assess the long-term effect of ultrathin-strut (60 μm) BP-SES versus thin-strut (81 μm) DP-EES on long-term outcomes in patients undergoing percutaneous coronary revascularization for small vessel disease. (ox.ac.uk)

Background: Multi-vessel coronary artery disease (MV-CAD) is correlated with worse clinical outcomes compared with single-vessel CAD (SV-CAD). (bgu.ac.il)

A unifying feature between the phenomenon in large and small vessels seems to be an increase in vascular wall tension. (birmingham.ac.uk)
image matrix 2480 × 1920 pixels) and especially flat detector CT with pixel sizes of 308 μm × 308 μm (2 × 2 binning), using a reconstructed section thickness of 0.1 mm and high-contrast resolution of CT and 3D reconstructions, provide a new basis to display these small vessels on recent flat detector neuroangiography systems. (ajnr.org)

however, there is a lack of consistent presentation of the small branches of the basilar artery in the imaging literature. (ajnr.org)
Compared with 2D DSA images, 3D DSA reconstructions allow superior visualization of the small branches of the basilar artery. (ajnr.org)
No zone of basilar artery is free from important side branches. (ajnr.org)
4 We hypothesized that the 3D-rotation technique allows superior visualization of the small branches of the basilar artery than 2D DSA images do. (ajnr.org)

Early diagnosis and treatment of a narrowed carotid artery can decrease stroke risk. (mayoclinic.org)
Construct a 3D model of the carotid artery to improve the accuracy of a diagnosis. (mayoclinic.org)

3 mm, respectively) did not stratify according to vessel size and failed to specify the impact of ultrathin-strut thickness on long-term clinical outcomes compared with durable polymer everolimus-eluting stents (DP-EES). (ox.ac.uk)
CONCLUSIONS: We found no significant difference in clinical outcomes throughout 5 years between patients with small vessel disease treated with ultrathin-strut BP-SES versus thin-strut DP-EES. (ox.ac.uk)

Based on our observations [ paper ], vessel wall structures in routine MR Knee scans are visible and analyzable. (clatfd.cn)
