Abstract:

The exemplary embodiments of this invention relate at least in part to a method, apparatus and system to characterize white matter, such as for detecting a presence of a white matter impairment. An exemplary method to characterize white matter includes identifying at least one tract of interest (TOI) in the brain of a subject of interest, the tract of interest having a set of streamtubes representing white matter fibers; determining a set of quantitative tractography metrics associated with the tract of interest, the set of quantitative tractography metrics having a plurality of members; and comparing at least one member of the determined set of quantitative tractography metrics to a corresponding member of a reference set of quantitative tractography metrics, or comparison of one TOI in a single subject or group of subjects and other TOI in the same subject(s).

Abstract:

Devices for performing fine-needle aspiration of tissue and methods of using the same are disclosed. The device includes a syringe including a fiber optic probe, a plunger, and a needle and a holder including a coupling mechanism, a first actuator, and a second actuator. The fiber optic probe is configured to move within a lumen of the needle and is guided into the needle by a fiber optic channel. The plunger is configured to create a vacuum in the needle.
