QuickMind MRI Clinical Evidence

ShareGAN generated synthetic amyloid-β PET from structural MRI using paired imaging from 1,009 participants across ADNI and three Chinese hospitals. Amyloid-status accuracy was 88.5% and 89.4% in two external test sets; the study explores support for selecting patients for confirmatory PET.

Evidence scope: Retrospective translational research. Synthetic PET is not a replacement for real amyloid PET or treatment eligibility assessment. This publication does not establish that MRI-to-PET synthesis is an available or approved Dr.Brain™ product module.

A study of 77 early-AD patients and 58 cognitively unimpaired participants combined Dr.Brain™ hippocampal measurements with VR eye-tracking assessment. The combined model had an AUC of 0.825, compared with 0.629 for hippocampal volume alone.

Evidence scope: Single-center, cross-sectional study with education imbalance. The combined model result is not a standalone product claim or proof of population-wide diagnostic performance.

An automated four-subtest Chinese neurocognitive battery was evaluated in 86 volunteers aged 51–82. Scores were compared with paper-based tests, and automated scoring showed correlations of 0.904–1.0 with manual scoring.

Evidence scope: A limited Chinese-language validation sample. Scoring agreement is not diagnostic sensitivity or a treatment effect. Equivalence to the marketed QuickMind or VECA configuration has not been established.

In the PUMCH dementia cohort, quantitative MRI of 111 patients with probable Alzheimer’s disease examined cortical volume, thickness and cognitive performance across mild, moderate and severe disease. Regional atrophy, especially in left temporoparietal and occipital areas, was associated with cognitive impairment.

Evidence scope: A cross-sectional cohort. Associations across severity groups do not establish longitudinal prediction, standalone diagnosis or treatment-response monitoring.

A retrospective comparison of 95 Alzheimer’s disease and 106 frontotemporal lobar degeneration cases integrated clinical, neuropsychological and neuroimaging findings. Dr.Brain™ volume and white-matter measurements contributed to the assessment of differing regional patterns.

Evidence scope: Retrospective, selected clinical groups. The study supports complementary differential assessment, without establishing a standalone Dr.Brain™ diagnostic classifier or population-screening accuracy.

Quantitative MRI compared 18 patients with type 2 diabetes and mild cognitive impairment, 18 with diabetes without MCI, and 18 healthy controls. Dr.Brain™ regional volumes were used to explore structural differences and classification features.

Evidence scope: A small, exploratory three-group study. Reported classification performance requires larger external validation and cannot be generalized to all patients with diabetes or cognitive symptoms.

This review describes MRI features and artificial-intelligence approaches for Alzheimer’s disease assessment, alongside the domestic and international software-approval landscape reported in 2022.

Evidence scope: Historical technical and regulatory context, not a clinical efficacy study or evidence of current approval in any market. Institutional affiliation does not imply regulatory endorsement of this website or product line.

A single patient with cognitive and behavioral changes underwent detailed neuropsychological assessment and multimodal imaging. The manuscript describes Dr.Brain™ regional-volume analysis as part of distinguishing frontal-variant Alzheimer’s disease from behavioral-variant frontotemporal dementia.

Evidence scope: A single illustrative case cannot establish diagnostic sensitivity, specificity or clinical efficacy. Quantitative MRI formed one part of a broader clinical and biomarker assessment.

Automated measurements were compared with manual measurements in 204 healthy MRI scans. A separate comparison of 34 Alzheimer’s disease cases and 34 controls examined 47 brain regions. The reported measurement agreement and regional-volume differences support further clinical investigation.

Evidence scope: A preliminary measurement study with a small disease-comparison cohort. Agreement with manual measurement is not diagnostic accuracy and does not establish longitudinal treatment benefit.

Across three Chinese MRI datasets, localized shape analysis identified hippocampal and amygdalar abnormalities associated with Alzheimer’s disease and mild cognitive impairment. Shape measures added information beyond whole-structure volume and correlated with cognitive scores.

Evidence scope: Research evidence for structural biomarkers; it does not establish the performance of every Dr.Brain™ module or current software version.

Deep-learning segmentation approaches were evaluated on two open MRI datasets, followed by regional white-matter hyperintensity analysis in 213 clinical cases with cerebral ischemia or lacunes. The study examines automated lesion delineation and anatomical localization.

Evidence scope: Algorithm and regional-imaging research, rather than a prospective clinical-outcome trial. Performance on these datasets does not establish equivalence to every current Dr.Brain™ software version.

High-resolution magnetic resonance spectroscopy examined postmortem frontal-cortex tissue from 11 Alzheimer’s disease cases and 11 controls. Metabolite differences, including glucose-related signals and APOE-associated patterns, were explored as a basis for further biomarker research.

Evidence scope: An ex vivo tissue study with a small sample. It does not validate a clinical screening test, quantitative MRI software or any marketed Dr.Brain™ module.

A review of MRI-based brain-age estimation and its potential as a research biomarker. It provides context for the brain-aging section of the English Brain Doctor report.

Evidence scope: Independent background literature. It does not validate the Dr.Brain™ brain-age model, provide a lifespan forecast, or supply an individual diagnostic threshold.
