Intraoperative color Doppler during manual vacuum aspiration prevents retained products of conception

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To investigate whether intraoperative confirmation of the disappearance of uterine cavity blood flow using color Doppler during manual vacuum aspiration (MVA) for missed miscarriage reduces the occurrence of retained products of conception (RPOC). Methods We conducted a retrospective cohort study of 202 patients who underwent MVA for

Core‐shell structure induced surface reconstruction of PbS quantum dots toward high‐detectivity short‐wave infrared photodetectors

open access: yesInfoScience, EarlyView.
We present a core‐shell structure‐induced surface reconstruction treatment for PbS quantum dots (QDs). Highly detective photodetectors and imagers in the short‐wave infrared region are demonstrated based on the surface‐reconstructed QDs with reduced dark current density and improved QD stacking configuration, as shown by grazing‐incidence small‐angle X‐

Preliminary Study on the Value of Contrast‐Enhanced Ultrasound in Enhancing Early Vascular Architecture for the Differential Diagnosis of Benign and Malignant Endometrial Lesions

open access: yesJournal of Clinical Ultrasound, EarlyView.
This study aimed to analyze the microvascular morphology and distribution (i.e., early vascular architecture) of endometrial carcinoma lesions during the early enhancement phase using contrast‐enhanced ultrasound (CEUS). The results confirmed that quantitative parameters based on the early vascular architecture possess certain diagnostic efficacy for ...

A Comparative Study of Ultrasonography and CT Venography in the Diagnosis of Budd‐Chiari Syndrome

open access: yesJournal of Clinical Ultrasound, EarlyView.
Budd‐Chiari syndrome (BCS) is characterized by hepatic venous outflow obstruction from the hepatic veins to the junction of the inferior vena cava (IVC) and right atrium. Ultrasound (US) and CT venography (CTV) are used as imaging techniques for the diagnosis of BCS, and We compared the diagnostic efficacy of the two modalities. The results showed that
