Recommended Imaging Inclusion

Users of the imaging data are advised to choose inclusion criteria that are appropriate for their analyses. We provide a set of recommended inclusion criteria for each modality that take into account factors such as imaging QC, task performance, etc., and for convenience, we provide an instrument mri_y_qc_incl with modality-specific imaging inclusion flags based on those criteria.

Automated post-processing QC metrics were statistically characterized in association with manual QC variables from ABCD Release 3.0. The statistical association between manual and automated QC variables was used to guide the identification of automated QC variables that were predictive of manual QC scores. The pairwise analysis of manual-vs-auto QC scores lead to automated QC variable thresholds needed to identify anomalous scans with desired false alarm ratings. For the variables listed below, the thresholds are listed to achieve conservatively low false alarm ratings of 0.05%.

• sMRI T₂w registration to T₁w: < 10
• dMRI registration to T₁w: < 17
• dMRI Maximum dorsal cutoff score: < 47
• dMRI Maximum ventral cutoff score: < 54
• fMRI registration to T₁w: < 19
• fMRI Maximum dorsal cutoff score: < 65
• fMRI Maximum ventral cutoff score: < 60

Notes:

• All imaging series have been manually reviewed at the preprocessing stage (“raw”). Series failing raw QC do not get processed (e.g., iqc_t1_ok_ser is 0 or empty).
• For task fMRI, the average degrees of freedom is set at an arbitrary 200; this can be increased for a more restrictive selection criteria. For single runs, the required degrees of freedom are halved (i.e., dof > 100).

MRI Clinical Findings

T₁w and T₂w-weighted images, if available, were screened for incidental findings by a Board Certified Neuroradiologist. Any findings requiring clinical investigation were relayed to appropriate site personnel via the ABCD Coordinating Center (CC).

The most important measure is the Report Score (mrif_score):

• 0 = Image artifacts prevent radiology read
• 1 = No abnormal findings
• 2 = Normal anatomical variant of no clinical significance
• 3 = Consider clinical referral
• 4 = Consider immediate clinical referral

Although not included in the recommended inclusion criteria, users may, depending on their research question and analytical design, opt to exclude participants with mrif_score != 3 OR mrif_score !=4.

MRI post-processing quality control

Our manual quality control process involves manual examination of brain images from a subset of participant-events for each modality, with ratings for each dataset according to pre-defined quality criteria such as brain cutoff, residual distortion, or registration to T₁. Such measures are described above (see FreeSurfer QC, sMRI T₂w Post Processing QC, dMRI Post Processing QC, and fMRI Post Processing QC). Because an exhaustive manual review of every scan is not practical, we deploy statistical learning/AI guided sub-sampling methods where we generate automated metrics for an array of quality control issues (see Automated Post Processing QC) and sub-select participant-events to be sent for a given modality to manual review based on their quality measure scores. The automatic selection priority scores generally indicate how likely a dataset of a given type is to contain identifiable data quality issues such as a residual distortion or brain cutoff. ABCD Release 4.0 manual review post processing sampling categories included the following four primary groups:

Failed post-processing QC from ABCD Release 3.0: All participant-events that failed QC for a given modality in Release 3.0 were manually reviewed again after Release 4.0 processing, with the expectation that they would be likely candidates for failure, unless perhaps recovered due to improvements in the current Release 4.0 processing pipeline. These made up about 25-50% of manually reviewed participant-events.

Random selection of participant-events: Roughly 5% of the manually reviewed participant-events were chosen at random to account for possible biases and insensitivities of the automated measures that guide the sub-sampling selection process.

Statistical outliers: ROI summary vectors for all individual participant-events are used to deduce a statistical ensemble profile. Participant-events with the greatest “distance” to the ensemble are tagged as outliers and selected for manual review. The formal framework we used for defining the ensemble statistics and the “distance” measure between a scan and the ensemble is based on the Mahalanobis distance (see https://en.wikipedia.org/wiki/Mahalanobis_distance). Mahalanobis distance is a scalar measure of the distance between a point P, defined in a multi-dimensional vector space, and a distribution D. In our case, participant-events are sorted based on their Mahalanobis distances, and our manual review goal targeted the top 5% of that list. These made up ~20-25% of manually reviewed participant-events.

Classifier guided selections: Using the manual scoring of the above sets, namely the random samples, Release 3.0 failures, and Mahalanobis distance outliers, we collected a subset of manually labeled scan data. For each participant-event we generated a set of automated measures described below in Automated Post Processing QC (automated review). Using binarized (pass/fail) manual quality control (QC) labels associated with these measures, we constructed a Bayesian classifier (see https://en.wikipedia.org/wiki/Bayes_classifier) that calculates the probability of QC failure associated with different types of QC issues (e.g., bad registration or brain cutoff) for any given dataset. Participant-events are sorted based on their QC failure probabilities, and roughly the top 3-5% were selected for manual review for each modality, making up ~30-50% of manually reviewed participant-events.

Methods

Image processing and analysis methods corresponding to ABCD Release 2.0.1 are described in Hagler et al., 2019, Image processing and analysis methods for the Adolescent Brain Cognitive Development Study. Neuroimage, 202:116091 (doi: 10.1016/j.neuroimage.2019.116091). Changes to image processing and analysis methods in Release 3.0 and Release 4.0 are documented below.

Changes for ABCD 3.0

Post processing QC and inclusion criteria

As in ABCD Release 2.0.1, FreeSurfer cortical surface reconstructions were reviewed for all participant-events that successfully completed FreeSurfer processing. New for Release 3.0, we used a sampling approach for dMRI and fMRI, wherein approximately 20% of the dMRI/fMRI sessions were manually reviewed for postprocessing dMRI/fMRI QC. We selected participant-events for review based on random-sampling, Bayesian classifiers based on automated QC metrics, and multivariate outlier detection. Recommended inclusion criteria were updated to include manual post-processing QC, new automated post-processing QC metrics, and additional variables (e.g., E-Prime timing match to imaging series). Modality-specific imaging inclusion flags are included in a new NDA data structure, abcd_imgincl01.

Protocol compliance

The determination of protocol compliance for scans from GE scanners (reflected for example in elements iqc_sst_1_pc_score or iqc_sst_total_passpc in NDA data structure mriqcrp202) was changed to use the “ImagesInAcquistion” DICOM header attribute rather than the number of DICOM files. Imaging series with missing files, i.e., fewer files than the ImagesInAcquisition, are marked as incomplete. For Siemens and Philips scans, the same DICOM header field recording the number of images collected is not available, and so series with fewer files than expected for the given series type are marked as incomplete.

Changes for ABCD 4.0

MRI raw QC

The MRI raw QC NDA data structures mriqcp103 and mriqcp203 were updated to reflect a remapping of the names and abbreviations used to categorize MRI raw QC issues. This was done to remove redundancy in the categories used previously. Also, QC issue variables were removed where inappropriate for a given scan type, such as the dMRI-specific “fa” (fractional anisotropy map issues) for sMRI or fMRI (e.g., iqc_mid_fa_qc).

QC issue names	Previously used names
field of view (fov)	dorsal cutoff (dco)
	ventral cutoff (vco)
	wrap around (wr)
susceptibility artifact (sus)	distortion (dis)
	signal dropout (sd)
	signal inhomogeneity (si)
horizontal banding (hb)	slice
	horizontal banding (hb)
other	flag
	other

Post processing QC and inclusion criteria

We extended the sampling approach used in Release 3.0 to include FreeSurfer, dMRI, fMRI, and sMRI T₂w post-processing QC. Approximately 2-7% of all participant-events were manually reviewed for post-processing QC for each modality. We selected participant-events for review based on post-processing QC failure in Release 3.0, multivariate outlier detection, Bayesian classifiers based on automated QC metrics, and random-sampling (~5% of total selected for review). Multivariate outlier detection was implemented using Mahalanobis distance calculated from the tabulated data (ROI averages) for a given imaging modality. Recommended inclusion criteria were updated to include manual post-processing QC for T₂w. A new manual post-processing QC NDA data structures was created for sMRI T₂w: abcd_t2wqc01.

The following manual post-processing QC NDA data structures were renamed:

• freesqc01 to abcd_fsurfqc01
• dmriqc01 to abcd_dmriqc01
• fmriqc01 to abcd_fmriqc01

Changes to data dictionaries

    • changes to DataType and Size for some elements
