This is a Small Business Sources Sought notice. This is NOT a solicitation for proposals, proposal abstracts, or quotations. The purpose of this notice is to obtain information regarding: (1) the availability and capability of qualified small business sources; (2) whether they are small businesses; HUBZone small businesses; service-disabled, veteran-owned small businesses; 8(a) small businesses; veteran-owned small businesses; woman-owned small businesses; or small disadvantaged businesses; (3) their size classification relative to the North American Industry Classification System (NAICS) code for the proposed acquisition. Your responses to the information requested will assist the Government in determining the appropriate acquisition method, including whether a set-aside is possible. An organization that is not considered a small business under the applicable NAICS code should not submit a response to this notice. This notice is issued to help determine the availability of qualified companies technically capable of meeting the Government requirement and to determine the method of acquisition. It is not to be construed as a commitment by the Government to issue a solicitation or ultimately award a contract. Responses will not be considered as proposals or quotes. No award will be made as a result of this notice. The Government will NOT be responsible for any costs incurred by the respondents to this notice. The purpose of this requirement is to obtain methodological and technical expertise in the processing of functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) as well as computed tomography (CT) images. These services will continue the established protocols and statistical approaches for the analysis of white matter correlates of alterations in functional connectivity as well as functional connectivity correlates of white matter alterations in the brain. In addition, this requirement will implement the image processing techniques developed during the prior period for the evaluation of body composition and bone morphometry in the abdomen and leg. The provision of these capabilities will facilitate the continued use of BLSA data in state-of-the-art imaging studies related to cognitive and motor function. The Contactor shall work in collaboration with BLSA investigators and study staff of the National Institute on Aging to provide image processing services as follows: For each type of brain imaging data the contractor shall retrieve data and co-register all image data into a common coordinate system. The Contractor will coordinate with the NIA to ensure that consistent common imaging reference spaces are used across projects. Apply image processing tools developed and validated under a prior contract. Define gray matter regions of interest. Targeted regions include the Hippocampus, Posterior Cingulate, Precuneus, and Medial Frontal cortex. DTI Pre-processing. The Contractor will perform and provide the Government with pre-processed image data, yielding fractional anisotropy (FA), mean diffusivity (MD), principal eigenvector (v1), and tensor (D) images for each subject. Define white matter tracts. The FA maps for each subject will be labeled with a white matter atlas (i.e., the Johns Hopkins Eve atlas). rs-fMRI Pre-processing. Pre-processing will yield functional connectivity maps for each gray matter and white matter region of interest. The Contractor shall use the defined gray matter regions of interest on structural data for rs-fMRI analysis. Region of Interest Analysis. The Contractor will generate and provide to the LBN, NIA a table of means and standard deviations of rs-fMRI, FA, and MD for all regions of interest. Implement mass-univariate temporal modeling. The Contractor shall work with the LBN/NIA team and their collaborators to implement temporal association inference models (e.g., causal ) to implement in current toolboxes. Characterize temporal inference in simulation. The Contractor shall perform data-driven simulations to verify that the inference method empirically performs according to theoretical predictions and is compatible with standard approaches for multiple comparisons corrections (e.g., false discovery rate [FDR]). Apply multi-modal temporal inference to BLSA 1.5T/3T cohort. The Contractor shall work with LBN investigators to execute structural-functional-covariate analysis in the form of a general linear model (GLM, voxelwise model of the form: ) where both the regressors and the regressands may be longitudinally sampled imaging variables. The temporal relationships between sequenced regressors and regressands will be assessed. Additional non-imaging data may be provided for each subject in the form of an Excel document. These will be run as additional regressors. Scanner calibration. The Contractor shall implement scanner calibration/correction, including modeling scanner changes as nuisance variables and using image preprocessing corrections. Apply image processing tools for BLSA MRI of the thigh, CT of the abdomen as well as CT of the leg. The Contractor shall perform segmentation and quantify regions of interest captured in the BLSA thigh MRI protocol including, but not limited to: subcutaneous fat, inter-muscular fat, and muscle. The Contractor shall perform segmentation and quantify regions of interest in images captured in the BLSA CT protocol including images of the abdomen, thigh, as well as the proximal, mid and distal tibia. Regions of interest include but are not limited to: Abdominal subcutaneous and visceral fat, Thigh subcutaneous fat, inter-muscular fat, muscle, and bone, Tibia subcutaneous fat, inter-muscular fat, muscle, and bone. The Contractor shall apply the image processing tools to both newly acquired images as well as the library of historical images to generate fully harmonized longitudinal thigh MRI and CT imaging data sets. Support method translation to NIA intramural researchers. The Contractor shall provide BLSA investigators and study staff with documentation of methods, including user manuals, and assist with installation and implementation of software as necessary. The Contractor shall document methodological contributions in the form of peer-reviewed publications. Copanies that believe they possess the capabilities to provide the required services should submit documentation of their ability to meet each of the project requirements to the Contracting Officer. The capability statement must specifically address each of the project requirements separately.
