Background: Neuroimaging is crucial in the diagnosis of Alzheimer's disease (AD). In recent years, artificial intelligence (AI) based neuroimaging technology has rapidly developed, providing new methods for accurate diagnosis of AD, but its performance differences still need to be systematically evaluated. Objective: To conduct a systematic review and meta-analysis comparing the diagnostic performance of AI-assisted fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG PET) and structural magnetic resonance imaging (sMRI) for AD. Methods: Databases including Web of Science, PubMed, and Embase were searched from inception to January 2025 to identify original studies developing or validating AI models for AD diagnosis using ¹⁸F-FDG PET or sMRI. Methodological quality was assessed using the Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis-Artificial Intelligence（TRIPOD-AI) checklist. A bivariate mixed-effects model was employed to calculate pooled sensitivity, specificity, and summary receiver operating characteristic curve area (SROC-AUC). Results: 38 studies were included, with 28 moderate-to-high-quality studies analyzed. Pooled SROC-AUC values were 0.94 (95% CI: 0.92–0.96) for sMRI and 0.96 (95% CI: 0.94–0.98) for ¹⁸F-FDG PET, demonstrating statistically significant intermodal differences (P=.02). Subgroup analyses revealed that in machine learning (ML), pooled SROC-AUCs were 0.89 (95% CI: 0.86–0.92) for sMRI and 0.95 (95% CI: 0.92–0.96) for ¹⁸F-FDG PET, while in deep learning (DL), these values were 0.96 (95% CI: 0.94–0.97) and 0.97 (95% CI: 0.96–0.99), respectively. Meta-regression identified heterogeneity arising from study quality stratification, algorithm types, and validation strategies. Conclusions: Both AI-assisted 18F-FDG PET and sMRI exhibit high diagnostic accuracy in AD, with 18F-FDG PET demonstrating superior overall diagnostic performance compared to sMRI.

Background: The global incidence of blindness has continued to increase, despite the enactment of a Global Eye Health Action Plan by the World Health Assembly. This can be attributed, in part to an aging population, but also to the limited diagnostic resources within lower- and middle-income countries (LMICs). The advent of generative artificial intelligence (#AI) (AI) within healthcare could pose a novel solution to combating the prevalence of blindness globally. Objective: The objectives of this study are to quantify the effect the addition of a complex prompt has on the diagnostic accuracy on a commercially available LLM, and to assess whether such LLMs are better or worse at diagnosing conditions that are more prevalent in LMICs. Methods: Ten clinical vignettes representing globally and LMIC-prevalent ophthalmological conditions were presented to GPT-4-0125-preview using simple and complex prompts. Diagnostic performance metrics, including sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV), were calculated. Statistical comparison between prompts was conducted using a Chi-Square Test of Independence. Results: The complex prompt achieved a higher diagnostic accuracy (90.1%) compared to the simple prompt (60.4%), with a statistically significant difference (χ² = 428.86; P < 0.01). Sensitivity, specificity, PPV, and NPV were consistently improved for most conditions with the complex prompt. The simple prompt struggled with LMIC-prevalent conditions, diagnosing only one of five accurately, while the complex prompt successfully diagnosed four of five. Conclusions: The study established that overall, the inclusion of a complex prompt positively affected the diagnostic accuracy of gpt-4-0125-preview, particularly for LMIC-prevalent conditions. This highlights the potential for LLMs, when appropriately tailored, to support clinicians in diverse healthcare settings. Future research should explore the generalisability of these findings across other models and specialties.
