Artificial Intelligence in Coronary Computed Tomography Angiography: From Anatomy to Prognosis

BioMed Research International, 2020
Cardiac computed tomography angiography (CCTA) is widely used as a diagnostic tool for evaluation of coronary artery disease (CAD). Despite the excellent capability to rule-out CAD, CCTA may overestimate the degree of stenosis; furthermore, CCTA analysis

In Situ Lipoprotein‐seeking Dye for in Vivo Real‐Time Imaging of Lipid Dysregulation Diseases

Advanced Science, EarlyView.
This study develops lipoprotein‐seeking NIR‐II dyes that specifically bind circulating lipoproteins. These dyes form ultra‐stable complexes with endogenous lipoprotein, enabling real‐time, high‐contrast imaging of fatty liver and atherosclerotic plaques. Tunable binding kinetics allow customized imaging windows.

Pneumatization of the sphenoid sinus, dorsum sellae and posterior clinoid processes in computed tomography [PDF]

, 2018
Purpose: Assessment of sphenoid sinus (SS), posterior clinoid process (PCP), and dorsum sellae (DS) pneumatisation is significant when planning surgical approaches both to intra- and extrasellar pathologies. The authors analysed pneumatisation of the SS,

Multimodal Optical Imaging and Modulation with Simultaneous Electrophysiology Through Smart Dura in Non‐Human Primates

Advanced Science, EarlyView.
This study demonstrates multimodal integration in non‐human primates, combining large‐scale, high‐density electrophysiology using Smart Dura with optical techniques such as multiphoton imaging (MPI), photothrombotic lesioning, optical coherence tomography angiography (OCTA), wide‐field intrinsic signal optical imaging (ISOI), and optogenetics.

Impact of incomplete ventricular coverage on diagnostic performance of myocardial perfusion imaging. [PDF]

, 2017
In the context of myocardial perfusion imaging (MPI) with cardiac magnetic resonance (CMR), there is ongoing debate on the merits of using technically complex acquisition methods to achieve whole-heart spatial coverage, rather than conventional 3-slice ...

Bio‐Inspired Micro‐Fin‐Assisted Multi‐Modal Vascular Intervention

Advanced Science, EarlyView.
A magnetic guidewire with a micro‐fin–integrated tip is introduced for multimodal cardiovascular navigation. The micro‐fins exploit fluid drag to augment magnetic torque, enabling bifurcation traversal at 15 mT, tolerating 45° misalignment, bidirectional crawling, and buckle self‐correction.
