We detail a new near-infrared fluorescence (NIRF) catheter for 2-dimensional intravascular molecular imaging of plaque biology in vivo. The NIRF catheter can visualize key biological processes such as inflammation by reporting on the presence of plaque-avid activatable and targeted NIR fluorochromes. The catheter utilizes clinical engineering and power requirements and is targeted for application in human coronary arteries. The following research study describes a multimodal imaging strategy...

Analysis of rodent cerebrovascular anatomy plays an important role in experimental stroke research. In this context, intravascular perfusion with colored latex has been considered as a standard tool for several years. However, this technique implies distinct technical limitations, which undermine its reproducibility. Here, we describe a simple method to visualize cerebral vessels in a reproducible manner. Injection of a mixture of two commercially available carbon black inks through the left...
FAQs
The key mechanistic advantage of intravascular injection is that blood flow becomes the immediate transport pathway. Because the material enters the vascular system directly, its distribution is governed by circulation rather than by absorption from a separate administration site. This makes the technique useful for examining how substances reach organs and for studying delivery through the vasculature.
Accurate vessel placement and controlled dosing are central because the method depends on delivering a known amount into the intended blood vessel. A misplaced needle or catheter can undermine the intended vascular delivery, while imprecise dosing can make results difficult to interpret. These controls therefore support reproducible biological experiments and safer use.
Unlike administration at a separate tissue site, intravascular injection does not require the material to be absorbed from that location before entering circulation. It also avoids first crossing tissue barriers at the administration site. This distinction makes the technique particularly relevant when investigators need to examine circulation or direct vascular access.
Direct vascular entry supports pharmacokinetic studies by placing the administered material within the circulation from the outset. Investigators can use the approach to examine how injected substances are carried through the vascular system and delivered to organs. The same logic supports studies of tracers, drugs, and experimental compounds in biological systems.
A basic workflow includes selecting an accessible blood vessel, positioning a needle or catheter within that vessel, and administering the substance in a controlled amount. Accurate placement is essential before delivery, because the intended outcome depends on vascular access. After administration, blood flow carries the material through the circulation for study.
The source material identifies needles and catheters as the primary devices for accessing a vein or artery. The injected substance may be a drug, tracer, cell preparation, or experimental compound, depending on the biological question. Together, the access device and controlled dose determine how the material enters and travels through the vascular system.
Researchers use intravascular injection when they need to investigate circulation, organ delivery, pharmacokinetics, or vascular function. The approach can administer drugs, tracers, cells, and experimental compounds directly through the vascular system. Its value lies in connecting a controlled administration event with observations of how materials move through blood vessels and reach tissues.
Intravascular injection provides a way to introduce a defined substance into the vascular system while examining the resulting distribution through blood vessels. In biology, this supports studies of vascular function alongside circulation and organ delivery. Tracers, drugs, cells, or experimental compounds can serve as the administered materials used to investigate these processes.
