Detectability of Al18F-NOTA-HER2-BCH PET for Nodal Metastases in Patients With HER2-Positive Breast Cancer.
Clin Nucl Med
January 2025
From the Key Laboratory of Carcinogenesis and Translational Research (Ministry of Education/Beijing), NMPA Key Laboratory for Research and Evaluation of Radiopharmaceuticals (National Medical Products Administration), Department of Nuclear Medicine; Peking University Cancer Hospital and Institute, Beijing, China.
Purpose: The aim of this study was to compare Al18F-NOTA-HER2-BCH and 18F-FDG for detecting nodal metastases in patients with HER2-positive breast cancer on PET/CT.
Patients And Methods: In this retrospective study, 62 participants with HER2-positive breast cancer underwent both Al18F-NOTA-HER2-BCH and 18F-FDG PET/CT. Participants were pathologically confirmed as HER2-positive (IHC 3+ or IHC 2+ with gene amplification on FISH).
Reference Values for Water-Specific T1, Intermuscular and Intramuscular Fat Content in Skeletal Muscle at 2.89 T.
J Magn Reson Imaging
January 2025
Department of Biomedical Engineering, University of Alberta, Edmonton, Alberta, Canada.
Background: MRI offers quantification of proton density fat fraction (PDFF) and tissue characteristics with T1 mapping. The influence of age, sex, and the potential confounding effects of fat on T1 values in skeletal muscle in healthy adults are insufficiently known.
Purpose: To determine the accuracy and repeatability of a saturation-recovery chemical-shift encoded multiparametric approach (SR-CSE) for quantification of T1 and muscle fat content, and establish normative values (age, sex) from a healthy cohort.
A Multi-Scale Computational Model of the Hepatic Circulation Applied to Predict the Portal Pressure After Transjugular Intrahepatic Portosystemic Shunt (TIPS).
Int J Numer Method Biomed Eng

Transjugular intrahepatic portosystemic shunt (TIPS) is a widely used surgery for portal hypertension. In clinical practice, the diameter of the stent forming a shunt is usually selected empirically, which will influence the postoperative portal pressure. Clinical studies found that inappropriate portal pressure after TIPS is responsible for poor prognosis; however, there is no scheme to predict postoperative portal pressure.

Introduction: The performance of a high quality esophagogastroduodenoscopy (EGD) is dependent on the mucosal cleanliness. Recently, the Polprep: Effective Assessment of Cleanliness in EGD (PEACE) scale was created to assess the degree of mucosal cleanliness during EGD. The aim of this study was to validate this scoring system in a cohort of international endoscopists.

Purpose: We aimed to determine fetal liver perfusion in PGDM and GDM pregnancies and to assess the relation of ductus venosus (DV) shunt fraction with adverse pregnancy outcomes.
Methods: We conducted a prospective longitudinal observational study including 188 pregnant women: group I-patients with pregestational DM (PGDM, n = 86), group II-patients with gestational DM (GDM, n = 44), group III-control (n = 58). The patients included in the study underwent ultrasound examination at 30-40 weeks of pregnancy.
