Two-Dimensional LF-NMR Spectroscopy for Graphene Oxide-Based Magnetic Relaxation Switching (GO-MRS) Biosensing: Feature Analysis and Predictive Modeling for Acetamiprid Detection.

The feasibility of using two-dimensional low-field nuclear magnetic resonance (2D LF-NMR) for detecting acetamiprid (ACE) residues was investigated based on a graphene oxide-based magnetic relaxation switching (GO-MRS) biosensor. Feature extraction and original spectral data analysis strategies were proposed for - spectral signal analysis. Then Pearson correlation, principal component regression, and partial least-squares regression were employed to develop the prediction model for ACE residues.

Accuracy of Preoperative Contrast-enhanced Cone Beam Breast CT in Assessment of Residual Tumor after Neoadjuvant Chemotherapy: A Comparative Study with Breast MRI.

Rationale And Objectives: To compare the accuracy of preoperative contrast-enhanced cone beam breast CT (CE-CBBCT) and MRI in assessment of residual tumor after neoadjuvant chemotherapy (NAC).

Materials And Methods: Residual tumor assessments in 91 female patients were performed on preoperative CE-CBBCT and MRI images after NAC. The agreements of tumor size between imaging and pathology were tested by Intraclass Correlation Coefficient (ICC).

Comparison of background parenchymal enhancement (BPE) on contrast-enhanced cone-beam breast CT (CE-CBBCT) and breast MRI.

Objectives: To compare the background parenchymal enhancement (BPE) levels on contrast-enhanced cone-beam breast CT (CE-CBBCT) and MRI, evaluate inter-reader reliability, and analyze the relationship between clinical factors and BPE level on CE-CBBCT.

Methods: In this retrospective study, patients who underwent both CE-CBBCT and MRI were analyzed. BPE levels on CE-CBBCT and MRI were assessed by five specialists independently in random fashion, with a wash-out period of 4 weeks.
