Methods: We retrospectively collected 399 infertile women who underwent HyCoSy by the same sonographer. These patients were divided into two groups according to the way how the assistants connected the syringe to the uterus radiography catheter to inject the contrast agent.
Objective: This study is aimed at identifying stemness-related genes in pancreatic ductal adenocarcinoma (PDAC).
Methods: The RNA-seq data of PADC patients were downloaded from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx) databases. The mRNA expression-based stemness index (mRNAsi) and epigenetically regulated mRNAsi (EREG-mRNAsi) of PADC patients were evaluated.
Article Synopsis
- The study examines how half-brain delineation can help predict radiation damage in the temporal lobes of patients with nasopharyngeal carcinoma (NPC) undergoing intensity-modulated radiotherapy (IMRT).
- A retrospective analysis of 220 NPC cases showed significant differences in radiation doses received by the temporal lobes compared to half-brains, with specific dosimetric parameters demonstrating varying degrees of prediction accuracy for temporal lobe injury (TLI).
- The findings suggest that using half-brain delineation simplifies the contouring process and provides reliable estimates for TLI risk, making it a practical approach for NPC patient treatment planning.
Aim: The study retrospectively analysed the accuracy of preoperative contrast-enhanced ultrasound (CEUS) in differenti-ating stage Ta-T1 or low-grade bladder cancer (BC) from stage T2 or high-grade bladder cancer.
Material And Methods: We systematically searched the literature indexed in PubMed, Embase, and the Cochrane Library for original diagnostic articles of bladder cancer. The diagnostic accuracy of CEUS was compared with cystoscopy and/or transurethral resection of bladder tumors (TURBT).
Background: Contrast-enhanced ultrasound (CEUS) is considered an attractive imaging technique to evaluate tumor microcirculation. However, the validity of CEUS for assessing laryngeal carcinoma is unclear.
Purpose: To compare the performance of CEUS with conventional US and contrast-enhanced computed tomography (CECT) in the diagnosis and preoperative T-staging of laryngeal carcinoma.
Objective: The aim of this study is to explore the potential pathogenesis of juvenile dermatomyositis by bioinformatics analysis of gene chips, which would screen the hub genes, identify potential biomarkers, and reveal the development mechanism of juvenile dermatomyositis.
Material And Methods: We retrieved juvenile dermatomyositis's original expression microarray data of message RNAs (mRNAs) and microRNAs (miRNAs) from NCBI's Gene Expression Omnibus database (GEO, http://www.ncbi.

Methods: Nude mice were divided into three groups according to experiments conducted at various times from tumor implantation (8 mice/group; group A: 4 weeks from implantation; group B:6 weeks from implantation; group C:8 weeks from implantation). CNE-2 cells were transplanted in 24 nude mice and CEUS evaluations of the tumors were performed at 4, 6 or 8 weeks from implantation.
Objective: The aim of this study was to investigate the characteristics of nasopharyngeal carcinoma (NPC) using contrast-enhanced ultrasonography (CEUS), including the enhancement patterns and the quantitative parameters.
Methods: Having been scanned using conventional ultrasonography (US) and CEUS, every case was confirmed to be NPC under endoscopic biopsy, and no case received any anti-tumor treatment before CEUS examinations. Tumor/node/metastasis stages were determined in accordance with 2002 AJCC 6th edition.
Objective: The aims of this study were to describe the relationship between the scanning planes and appearance of the upper airway on sonography and to demonstrate the reliability and reproducibility of sonographic measurements of the upper airway.
Methods: Airway sonoanatomy was recognized by comparing the airway images and the corresponding cadaver's anatomical specimens. Systemic sonographic examination of 267 healthy volunteers was conducted to obtain the sonographic measurement of airway lumen.
Sonography for diagnosis of benign and malignant tumors of the nose and paranasal sinuses.

September 2014
Objectives: The purpose of this study was to demonstrate the reliability of sonography for diagnosis of nose and paranasal sinus tumors.
Methods: Ninety-six consecutive patients with tumors underwent sonography and computed tomography (CT) before surgical treatment. Tumor detectability and imaging findings were evaluated independently and then compared with pathologic findings.
Objective: To compare the accuracy of ultrasonography (US) with the current clinical standard of endoscopy for a diagnosis of nasopharyngeal carcinoma (NPC).
Methods: A total of 150 patients suspected of having NPC underwent US and endoscopy. A diagnosis was obtained from an endoscopic biopsy collected from each suspected tumor and was compared with a biopsy obtained from a normal nasopharynx.
Objectives: The purpose of this study was to prospectively assess the accuracy of sonography versus magnetic resonance imaging (MRI) for a diagnosis of primary nasopharyngeal carcinoma.
Methods: A total of 150 patients suspected of having nasopharyngeal carcinoma underwent sonography and MRI. A diagnosis was obtained from an endoscopic biopsy that was collected from the suspected tumor or a normal nasopharynx.
Objective: To compare the accuracy of ultrasonography (US) with the current clinical standard of endoscopy for a diagnosis of nasopharyngeal carcinoma (NPC).
Methods: A total of 150 patients suspected of having NPC underwent US and endoscopy. A diagnosis was obtained from an endoscopic biopsy collected from each suspected tumor and was compared with a biopsy obtained from a normal nasopharynx.
Background: Contrast-enhanced ultrasound (CEUS) is a non-invasive method for the assessment of breast lesions. The accuracy of CEUS in diagnosing of breast cancer has never been systematically assessed.
