Abstract: The present invention provides a method of determining whether a subject is suffering or at a risk of developing a peripheral arterial disease via Positron Emitting Tomography (PET) imaging technology. The method comprises administering a PET radionuclide into the subject via automated generation and/or infusion system, performing PET scan of the region of interest, automated assessment of the PET images, performing assessment and suggesting the most appropriate therapeutic and/or management options for the patients based on the severity score, provides an assessment of regional lower proximity perfusion and perfusion reserve, and/or regional and mean standardized uptake values (SUVs). More particularly, the method of image processing identifies the regional differences in SMP (Skeletal muscle perfusion) and SMPR (Skeletal muscle perfusion reserve) across calf muscles at rest and cuff-induced hyperemia.

Abstract: It has been discovered that iron-platinum ferromagnetic particles can be dispersed in a polymer and coated into or onto, or directly linked to or embedded on to, medical devices and magnetized. The magnetized devices are used to attract, capture, and/or retain magnetically labeled cells on the surface of the device in vivo. The magnetic particles have an iron/platinum core. Annealing the Fe/Pt particle is very important for introducing a L10 interior crystalline phase. The Fe:Pt molar ratio for creation of the crystal phase is important and a molar range of 1.2-3.0 Fe to Pt (molar precursors, i.e. starting compounds) is desired for magnetization. The magnetic force as a whole can be measured with a “Super Conducting Quantum Interference Device”, which is a sensitive magnetometer. The overall magnetic force is in the range from 0.1 to 2.0 Tesla.

Abstract: Multivalent CT or MR contrast agents and methods of making and using thereof are described herein. The agents contain a moiety, such as a polymer, that provides multivalent attachment of CT or MR contrast agents. Examples include, but are not limited to, multivalent linear polymers, branched polymers, or hyperbranched polymers, such as dendrimers, and combinations thereof. The dendrimer is functionalized with one or more high Z-elements, such as iodine. The high Z-elements can be covalently or non-covalently bound to the dendrimer. The dendrimers are confined in order to enhance CT contrast. In some embodiments, the moiety is confined by encapsulating the dendrimers in a material to form particles, such as nanoparticles. In other embodiments, the dendrimer is confined by conjugating the moiety to a material, such as a polymer, which forms a gel upon contact with bodily fluids.
