High-resolution diffusion MRI of rectal cancer ex vivo surgical specimens reveals post-treatment microstructural characteristics of tissue components

Abstract Advances in organ-preserving rectal cancer treatment require accurate restaging after neoadjuvant therapy (NAT). However, standard tools - endoscopy and T 2 -weighted pelvic MRI - struggle to differentiate residual tumour from normal tissue and treatment-induced changes, yielding high specificity but low sensi...

Cross-attention fusion of biparametric MRI sequences with demographic and clinical variables for patient-level classification of clinically significant prostate cancer

Abstract Accurate patient-level risk stratification of clinically significant prostate cancer (csPCa) on biparametric MRI remains challenging, as most existing approaches require costly lesion-level annotations or have not been evaluated in large temporally separated cohorts. We developed and validated a multimodal dee...
