MRI Proton Density Fat Fraction as a Biomarker of Marrow Recovery Following Organ‐Sparing Total Marrow Irradiation in Sickle Cell Disease

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Noninvasive quantitative assessment of marrow recovery after curative therapies such as total marrow irradiation (TMI) and bone marrow transplantation (BMT) remain poorly defined, particularly in sickle cell disease (SCD). Purpose To evaluate MRI‐derived proton density fat fraction (PDFF) as a biomarker of marrow recovery following ...

Comparison of Continuous‐Time Random Walk and Fractional Order Calculus Diffusion Models for Preoperative Breast Lesion Characterization: Diagnosis, Biomarker Prediction and Molecular Subtyping

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Accurate preoperative characterization of breast lesions is important for individualized management. The conventional monoexponential (Mono) model has limited ability to capture the complex microstructure of lesions. Non‐Gaussian diffusion models, including continuous‐time random walk (CTRW) and fractional‐order calculus (FROC), may

Prognostic Value of Combined FDG PET and MRI Analysis of Cervical Cancer: A Systematic Review and Meta‐Analysis

Journal of Medical Radiation Sciences, EarlyView.
This systematic review and meta‐analysis synthesised FDG PET/MRWE biomarkers in cervical cancer, including a pooled analysis of the association between metabolic activity (SUV‐based metrics) and tumour diffusion characteristics (ADC measures). Prognostic evidence from the included studies was also analysed to identify PET‐ and MRI‐based parameters, as ...

Multiparametric MRI–based radiomic models for early prediction of response to neoadjuvant systemic therapy in triple-negative breast cancer

Scientific Reports
Triple-negative breast cancer (TNBC) is often treated with neoadjuvant systemic therapy (NAST). We investigated if radiomic models based on multiparametric Magnetic Resonance Imaging (MRI) obtained early during NAST predict pathologic complete response ...

Optimising hypoxia PET imaging and its applications in guiding targeted radiation therapy for non‐small cell lung cancer: a scoping review

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 106-118, March 2025.
This review article reports that quantification of hypoxic volumes using PET in the pre‐radiation therapy setting is of prognostic value and indicative of treatment response in non‐small cell lung cancer. Abstract Introduction Non‐small cell lung cancer (NSCLC) is the leading cause of cancer‐related death. Definitive treatment includes chemotherapy and
