Comparative study between PET-CT simulation and CT for head and neck cancer treatment and their potential effect on the thyroid gland: a prospective comparative study
Oncology Imaging 1 min.
Radiotherapy (RT) plays a key role in multidisciplinary treatment of Head and neck cancers (HNCs). Over the past two decades, advances have improved RT's tumor control and toxicity profiles. Precise delineation of gross tumor volume and organs at risk using CT and PET-CT is crucial for safe and effective...
Artifact reduction and diagnostic value of monoenergetic reconstructions from split-filter and dual-layer spectral detector dual-energy CT in early gastric cancer with titanium clip localization
Oncology Imaging 5 min.
Metal artifacts in CT imaging often manifest as bright and dark streaks that obscure anatomical details, complicating clinical evaluations [1]. To mitigate artifacts introduced by metallic implants, several advancements are available, including hardware modifications, optimization of imaging protocols,...
[18F]AlF-NOTA-PCP2 PET/CT to Assess PD-L1 Status in Head and Neck Cancer: Head-to-Head Comparison With [18F]FDG PET/CT.
Oncology Imaging 1 min.
While PD-L1 expression heterogeneity limits the predictive value of localized biopsies, molecular imaging offers a dynamic alternative. We developed [18F]AlF-NOTA-PCP2, a hydrophilic PD-L1-targeted peptide tracer, and first evaluated its clinical utility in head and neck (HNC) cancer through a head-to-head...
Interpretable deep learning for multicenter gastric cancer T staging from CT images
Oncology Imaging 5 min.
Gastric cancer is a major global health burden and remains among the top causes of cancer-related deaths worldwide1. Despite advances, many patients still present with advanced disease due to limited early detection, complicating treatment2. Accurate preoperative T staging guides decisions from endoscopic...
