This study presents a systematic literature review (SLR) of AI-driven medical imaging research focusing on classification-based models and explainability approaches in pneumonia detection. Using predefined inclusion criteria and PRISMA-guided screening, 95 studies were synthesized to identify dominant architectures, dataset trends, performance patterns, and persistent challenges. The analysis shows that convolutional neural networks (CNNs) and their variants remain the most frequently adopted models, accounting for the largest proportion of applications across x-ray, computed tomography scan (CT scan), and magnetic resonance imaging (MRI). Reported diagnostic performance across reviewed studies commonly exceeded 90% in accuracy and AUC, with models such as DeepMediX, XNet, Wavelet-CNN, and RadCLIP demonstrating strong predictive capability in their respective experimental settings. However, the review identifies significant gaps in explainability, clinical workflow integration, ethical compliance, and trust evaluation. Thus, this paper proposes a clinician-centric explainable artificial intelligence (CC-XAI) framework derived from literature synthesis. The framework integrates multilevel explainability, contextual clinical alignment, and human-in-the-loop feedback mechanisms to bridge the gap between black-box AI systems and real-world clinical practice. Rather than introducing a new predictive model, the framework provides a structured design blueprint for embedding explainability into medical imaging diagnostics. The findings highlight the continued dominance of deep learning in medical imaging while emphasizing the urgent need for clinician-oriented XAI frameworks to support transparency, trust, and responsible AI deployment in healthcare.</p>","PeriodicalId":47063,"journal":{"name":"International Journal of Biomedical Imaging","volume":"2026 ","pages":"6366492"},"PeriodicalIF":1.3,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13107166/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147785551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Computer-aided diagnosis provides significant support in this direction. This work introduces a new system called MF-BIMFs for computer-aided diagnosis that automatically analyzes digital mammograms to discover areas of interest in breast images and offers experts a second opinion. This system was based on the combination of two steps. The first step is the image preprocessing which was based on the bidimensional empirical mode decomposition (BEMD) of breast mammographic images, and their objective is to decompose the image into several BIMF modes and the residual, while the second step is the extraction of features and irregularity properties of the preprocessed images from the multifractal spectrum on each BIMF and the residual and to extract a better representation of each mode and provide details capable of differentiating the two healthy and cancerous states, using these properties as characteristic attributes to evaluate their performance in characterizing two conditions objectively. The rate of this classification is given by SVM. The experimental results indicate that the BIMF₁ mode provided the best classification rate, approximately 97.32%.
