Study for the Evaluation of the Feasibility of Applying Advanced MRI Scanning in Pediatric Clinical Practice

Study Overview
=================
Brief Summary
-----------------
The purpose of this research study is to evaluate the feasibility in conducting advanced MRI sequences in a pediatric clinical setting. The study will be observational in nature, and will only evaluate the studies of pediatric patients who have already been prescribed an advanced MRI for clinical neurological purposes. The only difference for the subject in participating in this study is that the data and information about their scan can be used and disclosed for research purposes, i.e. understanding if the time of the scan, patient comfort, and quality of the data are feasible. Standard MRI's have been extremely beneficial in the diagnosis and assessment of disease, injury, and anomalies throughout the body. Adding advanced MRI sequences to the arsenal of current standard MRI sequences, as well as analyzing the clinical significance of the data, may improve the benefits of MRI in the future. Within this scope, the study will be looking at the following factors: The total time of the scan, including: Patient arrival time/lateness Patient preparation time Time scanner is being occupied Patient compliance (is the patient continually stopping the study for breaks, fear, movement, etc.) Patient dropout rate, including: Change of mind Cost of study is too much Failure to finish the scan Usability of data, including: Movement artifact Patient requiring re-scan for any reason The scan will consist of two to five advanced MRI sequences that will average between 7-15 minutes each, in addition to a routine 5 minute standard MRI sequence. The variability in the number of advanced sequences depends on the prescription and patient history. All sequences are performed using a 1.5 Tesla Siemens MRI scanner at Westwood Open MRI, a 3 Tesla GE scanner at Tower Saint John's Imaging, or a 3 Tesla Siemens MRI scanner at Resolution Imaging. All scanners are FDA-approved.

Detailed Description
-----------------
An MPRAGE is a high quality anatomical image of the brain. This is used as an anatomical overlay, so that all data collected from the advanced sequences below can be correlated with the correct brain areas in three-dimensional space. Resting BOLD - BOLD stands for blood oxygen level dependent. This functional sequence allows for the viewing of the thinking brain at rest, and looks at brain areas that are functionally working together at the same time. The brain is in one of its most active states when it is at rest, and literature has shown that a few neurological illnesses such as OCD, depression, and pain have been associated with analyzing the data in this sequence. Arterial Spin Labeling (ASL) - ASL tracks the blood flow in the brain visually and gives a statistical value of how much blood is in each region in cc's per 100 grams of brain per second. Diffusion Tensor Imaging (DTI) - DTI tractography shows the different fiber tracts in the brain using a 3D model. Fiber tracts are the physical neural pathways that can show disruption or connection in communication between different areas of the brain. This is an effective technique when looking at traumatic brain injury. Magnetic Resonance Spectroscopy (MRS) - MRS measures the ratios of select chemical compounds in the brain in relation to each other. This has shown to be effective in analyzing memory loss, dementia, and Alzheimer's type disorders. Stimulated BOLD - The same sequence as the resting BOLD, except the brain is being scanned during the completion of a task, instead of rest. By specifying the task (visual, problem solving, language, etc.), the different areas of the brain working together to complete this task can be imaged. This is very effective for task-specific symptoms and deficits. The methods and procedures in this study are all under the observational category. MRI's are FDA approved and are non-experimental devices. The goal of this research is to assess the feasibility of the scan itself, so everything done with respect to the scan is considered observational in nature. If the subject drops out of the study, anything described in this protocol will still be able available to the subject as standard medical care. The observational procedures will involve recording data for the advanced MRI scans, and no information will be shared for research if the subject does not sign the consent form.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of subjects who successfully complete an fMRI scan | In order to assess scan feasibility, we will keep track of the total number of patients who sign the consent form and are able to complete the fMRI scan. | Through study completion, an average of 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Subject appointment time vs. subject arrival time | For each study subject, we will record the scheduled fMRI appointment time vs. the time that the subject arrives. | Through study completion, an average of 1 year | 
| Time it takes subject to get from checked-in to start of scan (in minutes) | For each study subject, we will record how long it takes to transition the subject from check-in to starting the fMRI scan. | Through study completion, an average of 1 year | 
| How long was the scanner unoccupied (in minutes) | We will record the length of time that the scanner is unoccupied in between scans. | Through study completion, an average of 1 year | 
| Number and type of sequences performed | For each study subject, we will record the number and type of sequences performed for the fMRI scan, e.g. MPRAGE, ASL, Resting BOLD, etc. | Through study completion, an average of 1 year |
