简要总结
The purpose of this study is to test the accuracy of using an imaging technique called breath-holding functional magnetic resonance imaging (BH fMRI) in addition to the standard imaging test described above. This study will allow the researchers to find out whether using BH fMRI in combination with the standard approach is the same as, better, or worse than the standard approach used alone.

入选标准
- •Health Volunteers
- •Volunteers between the ages of 18 and 80 years
- •Volunteers must be able to perform the language paradigms on cue while inside the scanner Patients
- •Patients between the ages of 18 and 80 years
- •Patients must be able to perform the language paradigms on cue while inside the scanner
- •Women of child bearing potential must have a negative pregnancy test prior to the study intervention (Serum or Urine)
- •Patients diagnosed with primary glial neoplasm, meningioma and metastasis (from prior histology) or must be suspected to have primary glial neoplasm, meningioma and metastasis on imaging (to be confirmed by post-operative histology).
- •Patient"s location of the tumor must involve the expected location of Broca"s area (left pars opercularis and/or pars triangularis), or the expected location of the primary motor area (the pre-central gyrus). This determination will be made on the basis of a pre-operative MRI by a fellowship-trained Neuroradiologist

研究组 & 干预措施
Functional Magnetic Resonance Imaging (fMRI)
The interventions for this study are non-invasive. For patients, routine pre-operative MRI that includes task based fMRI and perfusion data acquisition will be performed on a 3T scanner. Patients who participate in this study, will have approximately 5 minutes added to their scan time for the below described breath holding fMRI (BH fMRI) paradigm, which will be done for research purposes. For healthy volunteers, participation will involve having a high resolution anatomical MRI done with the same paradigms which patients will have, listed below. the total scanner time will be approximately 25 minutes, and the scan will not be billed to the healthy volunteer.

结局指标
主要结局
Number of patients that have false negative results
时间窗: 2 years
The primary objective is to examine if the false negative results of BOLD fMRI adjacent to brain tumors can be compensated for by measurements of BH-MRI and subsequent calibration of the BOLD response. We will have two sets of data: 1) the data obtained using routine techniques to analyze the BOLD fMRI data; and 2) the data obtained where the BOLD fMRI data was analyzed incorporating BH data. Every data point obtained in 1) will have a corresponding data point using 2), the BH MRI data, to adjust the BOLD fMRI analysis.
