Conventional imaging and biopsy may not adequately reflect whole-tumor biology because of spatial sampling limitations. Multiparametric magnetic resonance imaging (MRI), including dynamic contrast-enhanced MRI (DCE-MRI) and diffusion-weighted imaging (DWI), provides quantitative biomarkers related to tumor vascularity and cellularity. The aim of this study was to evaluate the association between quantitative DCE-MRI parameters and apparent diffusion coefficient (ADC) values across osteosarcoma subtypes and to explore their role in reflecting histopathologic heterogeneity.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Material and methods: &lt;/strong&gt;This retrospective exploratory study included 43 patients with histopathologically confirmed osteosarcoma who underwent pre-treatment 3.0-T MRI, including DCE-MRI and DWI, between January 2023 and February 2025. The cohort consisted of 17 osteoblastic, 9 fibroblastic, 6 chondroblastic, 5 giant cell-rich, 5 telangiectatic, and 1 extraskeletal osteosarcoma cases. Quantitative pharmacokinetic parameters (K&lt;sup&gt;trans&lt;/sup&gt;, K&lt;sub&gt;ep&lt;/sub&gt;, and V&lt;sub&gt;e&lt;/sub&gt;) were derived using the Tofts model, while ADC values were obtained from diffusion-weighted sequences. Inter-subtype differences were evaluated using the Kruskal-Wallis test and Dunn-Bonferroni post hoc analyses. Receiver operating characteristic (ROC) analysis and multivariable logistic regression were performed to assess diagnostic performance.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;K&lt;sup&gt;trans&lt;/sup&gt; demonstrated the strongest discriminatory performance across osteosarcoma subtypes (&lt;i&gt;H&lt;/i&gt; = 13.852, &lt;i&gt;p&lt;/i&gt; = 0.017), with significantly higher values observed in chondroblastic compared with telangiectatic tumors. ROC analysis demonstrated good diagnostic performance of K&lt;sup&gt;trans&lt;/sup&gt; in identifying osteoblastic (area under the curve [AUC] = 0.806, 95% confidence interval [CI]: 0.652-0.960, &lt;i&gt;p&lt;/i&gt; = 0.021) and chondroblastic (AUC = 0.775, 95% CI: 0.611-0.939, &lt;i&gt;p&lt;/i&gt; = 0.033) subtypes.
