PURCHASE DESCRIPTION

1. Statement of Need and Purpose: FMRIF wishes to procure a 32-channel radiofrequency (RF) head coil that will allow collection of data compatible with the multi-site Adolescent Brain Cognitive Development (ABCD) Study on General Electric’s (GE)

MR-750 3 Tesla MRI scanners operated by FMRIF. While FMRIF has the software to acquire the data from this protocol on its scanners, it lacks the hardware to allow a fully matched acquisition of these data. FMRIF now also possesses a multi-band, multi-echo capable Echo-Planar Imaging (EPI) sequence from GE. Testing confirms discussions at recent ISMRM meetings that while it is possible to acquire multi-band data with GE’s head coil, it is not recommended, as the geometry of that coil causes it to perform very poorly at higher multi-band factors (such as the factor of 6 used in the ABCD study). To fully utilize the potential of multi-band EPI sequences on FMRIF’s MR-750 scanners, it is imperative to have a coil with a more complex spatial arrangements of elements available for FMRIF’s MR-750 scanners, which will allow the usage of higher multi-band factors.

2. Background Information and Objective: FMRIF currently operates 5 MRI scanners that are used by researchers primarily in Intramural Research Programs at NIMH and

NINDS, but also other institutes at NIH, to conduct a variety of basic science and clinical research MRI scans, on healthy volunteers and patients. Keeping these scanners up to data with latest hardware and software is a core responsibility of FMRIF, so as to provide it users with the cutting-edge tools being used for research. As part of this mission, FMRIF seeks to procure hardware that will allow users to collect data that is fully matched to the ABCD protocol, and in doing so, allow the collection of Functional

MRI data with multi-band factors up to 6 along the Superior-to-Inferior (S-I, or head-foot) axis of a human subject.

3. Generic Name of Product: ABCD protocol compatible 32-channel MRI head coil for GE

MR-750 3T MRI Scanner.

4. Purchase Description: 32-channel MRI head coil for General Electric MR-750 3T MRI

Scanner.

5. Salient characteristics: Item must:

• Be hardware and software compatible with General Electric’s MR-750 3T MRI scanner hardware and software, including, but not limited to FMRI, ARC, ASSET, HyperBand, CUBE, and PROMO applications.

• Have full 510k clearance from the US Food and Drug Administration (FDA).

• Have at least 32 channels from which signal can be received from the subject or object being imaged.

Version 11-30-2016-1 FAR Part 11—Describing Agency Needs

• Be able to acquire data with slice-accelerated (multi-band, a.k.a. simultaneous multi-slice, a.k.a. SMS, a.k.a. HyperBand) factors greater than 2 along the head-to-foot

(superior-to-inferior) axis of a human subject.

• Provide compatibility with data acquisition for the ABCD protocol, allowing Functional

MRI (FMRI) data to be acquired with a SMS factor of 6, and Diffusion Tensor Imaging

(DTI) data to be acquired with a SMS factor of 3, along the head-to-foot (superior-to-inferior) axis of a human subject.

• Provide flexible patient mirror mounting options to allow visual stimulus delivery via either front- or rear- -mounted screens.
