Method to diagnose and measure vascular drainage insufficiency in the central nervous system

A technical system for identifying vascular drainage insufficiency in the central nervous system, the system comprising:

• a non-transitory computer readable medium for storing computer executable programmed modules;
• a processor communicatively coupled with the non-transitory computer readable medium for executing programmed modules stored therein;
• an image acquisition module stored in the non-transitory computer readable medium and configured to be executed by the processor to obtain functional magnetic resonance imaging (“fMRI”) data based on blood oxygen level dependence (“BOLD”);
• a hemodynamic response (“HDR”) module stored in the non-transitory computer readable medium and configured to be executed by the processor to convert the fMRI/BOLD data to HDR data, said HDR data comprising a graph of the BOLD over time;
• wherein the HDR module is further configured to be executed by the processor to analyze the HDR data and identify a negative trough in the HDR data to determine an abnormal HDR response and identify a vascular drainage insufficiency in the central nervous system based on said abnormal HDR response.

A computer implemented method for identifying vascular drainage insufficiency in the central nervous system, comprising:

• obtaining, using one or more processors, functional magnetic resonance imaging (“fMRI”) data based on blood oxygen level dependence (“BOLD”);
• converting, using the one or more processors, the fMRI/BOLD data to hemodynamic response (“HDR”) data comprising a graph of the BOLD over time;
• analyzing, using the one or more processors, the HDR data to determine an abnormal HDR response by identifying a negative trough in the HDR data;
• identifying, using the one or more processors, a vascular drainage insufficiency in the central nervous system based on said abnormal HDR response.

A non-transitory computer readable medium having stored thereon one or more sequences of instructions for causing one or more processors to perform the steps for identifying vascular drainage insufficiency in the central nervous system, the steps comprising:

• obtaining functional magnetic resonance imaging (“fMRI”) data based on blood oxygen level dependence (“BOLD”);
• converting the fMRI/BOLD data to hemodynamic response (“HDR”) data comprising a graph of the BOLD over time;
• analyzing the HDR data to determine an abnormal HDR response by identifying a negative trough in the HDR data;
• identifying a vascular drainage insufficiency in the central nervous system based on said abnormal HDR response.
