Development and Evaluation of Magnetic Resonance Imaging Acquisition and Analysis Methods

Study Overview
=================
Brief Summary
-----------------
Magnetic resonance imaging (MRI) is a diagnostic imaging method with constant progress and improvement in the way the MRI images are obtained. Many of these advances involve changes to MRI software and hardware. The goal of this study is to find out the possible benefits of new MRI techniques. This will allow us to use the new MRI methods in research and patient care.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: MRI<br>Add-On Research Patients will include patients who are scheduled for a routine clinical MRI who meet the eligibility requirements for this protocol. Protocol participation will consist of an add-on research. MRI scan, which will be performed any point during of the routine clinical MRI scan. Volunteers will be subjects expressing interest in participation and who meet the eligibility requirements for this protocol. No contrast enhanced research MRIs including gadolinium-based or other contrast agents will be performed in volunteers. | Behavioral: MR Screening Questionnaire<br>* All participants will complete the MR Screening Questionnaire before the MRI exam. During the MRI exam, all participants will be observed through the window from the operator console. Verbal communication will be kept with the participant throughout the exam via a speaker system.<br>Device: Magnetic Resonance Imaging Acquisition and Analysis<br>* MRI Studies: The MRI scans will be performed on a 1.5T or 3T MRI scanner. Conventional MRI studies will be performed using the standard clinical sequences. The new research sequences will be performed.at any point during the clinical exam. Total imaging time for volunteers will be 30-45 minutes.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| feasibility of new MRI applications | This protocol will provide pilot data to determine the feasibility of development and optimization of new MRI acquisition and analysis method.including sequence development, optimization, and workflow and analysis/visualization tools. An investigator will view the conventional images, as well as the additional research sequences. The radiologist will then complete data forms for each image and quantitative values, as listed in the evaluation form will be recorded. After all images have been read, the radiologist will review the clinical images together with the research images, and determine whether the research sequences had any effect on their diagnostic confidence. | 5 years |
