Intravascular blood pool

“Intravascular blood pool” does **not refer to a specific molecular target, receptor, protein, or therapeutic entity**. Instead, it is a descriptive term used in imaging science for the volume of blood contained within the vascular system (arteries, veins, capillaries), often as the compartment visualized during diagnostic procedures using blood pool (intravascular) imaging agents[2][3][6]. These agents (commonly contrast agents such as albumin-binding gadolinium complexes or liposomal iodinated agents) are designed to remain within the vascular space for a prolonged period, enhancing visualization of blood vessels and vascular abnormalities in MRI, CT, or other modalities[2][3][4][6]. "Intravascular blood pool" itself is therefore **not a molecular target, receptor, enzyme, or druggable entity**, but rather a physiological compartment or imaging concept. **Additional context:** - **Blood pool agents** are used in radiology to enhance imaging of the intravascular space and are not molecularly specific targets[2][3][6]. - Examples of such agents include gadofosveset (Ablavar), Ferumoxytol, Gadomer-17, and various PEGylated liposomal contrast agents[2][4][6]. - While research often discusses manipulation or measurement of the intravascular blood pool (e.g., observing blood vessel perfusion, microvascular permeability), the “intravascular blood pool” itself is the blood compartment, not the molecule or receptor being targeted[1][4][5]. - This term may be mistakenly submitted as a target, but it **does not correspond to a drug or therapeutic target** and thus should be flagged as incorrect in a drug-target database.
