- Multiparametric MRI-based Interpretable Machine Learning Radiomics Model for Distinguishing Between Luminal and Non-luminal Tumors in Breast Cancer: A Multicenter Studyby Yi Zhou, Guihan Lin, Weiyue Chen, Yongjun Chen, Changsheng Shi, Zhiyi Peng, Ling Chen, Shibin Cai, Ying Pan, Minjiang Chen, Chenying Lu, Jiansong Ji, Shuzheng Chen on April 1, 2025 at 12:00 am
To construct and validate an interpretable machine learning (ML) radiomics model derived from multiparametric magnetic resonance imaging (MRI) images to differentiate between luminal and non-luminal breast cancer (BC) subtypes.
- Generating Synthetic T2*-Weighted Gradient Echo Images of the Knee with an Open-source Deep Learning Modelby Konstantinos Vrettos, Evangelia E. Vassalou, Grigoria Vamvakerou, Apostolos H. Karantanas, Michail E. Klontzas on April 1, 2025 at 12:00 am
Routine knee MRI protocols for 1.5 T and 3 T scanners, do not include T2*-w gradient echo (T2*W) images, which are useful in several clinical scenarios such as the assessment of cartilage, synovial blooming (deposition of hemosiderin), chondrocalcinosis and the evaluation of the physis in pediatric patients. Herein, we aimed to develop an open-source deep learning model that creates synthetic T2*W images of the knee using fat-suppressed intermediate-weighted images.
- Quantification of Intratumoral Heterogeneity Based on Habitat Analysis for Preoperative Assessment of Lymphovascular Invasion in Colorectal Cancerby Yexin Su, Hongyue Zhao, Zhehao Lyu, Peng Xu, Ziyue Zhang, Huiting Zhang, Mengjiao Wang, Lin Tian, Peng Fu on April 1, 2025 at 12:00 am
Preoperative knowledge of the status of lymphovascular invasion (LVI) status in colorectal cancer (CRC) patients can provide valuable information for choosing appropriate treatment strategies. This study aimed to explore the value of heterogeneity features derived from the habitat analysis of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET) images in predicting LVI.
- Evaluating CT Dose Variation Across Scanner Technologies: Implications for Compliance with New CMS CT Radiation Dose Measureby Madan M. Rehani, Maria T. Mataac, Xinhua Li on April 1, 2025 at 12:00 am
In 2025, the Centers for Medicare and Medicaid Services introduced a computed tomography (CT) dose measure for pay-for-performance programs. Hospitals employ diverse scanner fleets, but the impact of scanner technologies on dose benchmarking remains unclear. This study evaluates dose variation across scanner models and its benchmarking implications.
- The 2024 Association of Academic Radiologists and Industry Think Tank: Unmet Clinical Needs and Collaborative Resourcingby Kara Gaetke-Udager, Christopher Hess, Mary Mahoney, Jeffrey G. Jarvik, Pablo R. Ros on March 31, 2025 at 12:00 am
As in prior years (1–4), the Association of Academic Radiologists (AAR), formerly the Association of University Radiologists (AUR), convened a session at its annual meeting with leaders from both academic radiology and industry. For this eighth annual gathering on Tuesday, April 2, 2024, the event took the form of a think tank, focusing on the topics of unmet clinical needs in radiology and methods of collaborative resourcing. Participants included those in person at the meeting in Boston, MA, and others attending via Zoom (Zoom Video Communications, San Jose, CA).
