A CT-based radiomics nomogram for predicting early recurrence in patients with high-grade serous ovarian cancer.

Purpose: To develop and validate a radiomics nomogram for predicting early recurrence in high-grade serous ovarian cancer (HGSOC) patients.

Materials And Methods: From May 2008 to December 2019, 256 eligible HGSOC patients were enrolled and divided into training (n = 179) and test cohorts (n = 77) in a 7:3 ratio. A radiomics signature (Radscore) was selected by using recursive feature elimination based on a support vector machine (SVM-RFE) and building a radiomics model for recurrence prediction.

Accuracy of flow-void diameters on MR images in diagnosing uterine arteriovenous malformations in patients with pregnancy-related diseases.

To evaluate the "flow void" diameter in patients with pregnancy-related diseases with and without uterine AVMs and assess the diagnostic performance of unenhanced MRI for uterine AVMs. From May 2014 to April 2019, 79 patients with pregnancy-related diseases were included, including 36 with and 43 without uterine AVMs confirmed by DSA. On MRI, the diameter of the most prominent "flow void" (hereinafter referred to as fv-D) was measured and compared between patients with and without uterine AVMs.

The Development and Validation of a CT-Based Radiomics Nomogram to Preoperatively Predict Lymph Node Metastasis in High-Grade Serous Ovarian Cancer.

Purpose: To develop and validate a radiomics model for predicting preoperative lymph node (LN) metastasis in high-grade serous ovarian cancer (HGSOC).

Materials And Methods: From May 2008 to January 2018, a total of 256 eligible HGSOC patients who underwent tumor resection and LN dissection were divided into a training cohort (n=179) and a test cohort (n=77) in a 7:3 ratio. A Radiomics Model was developed based on a training cohort of 179 patients.

Ultrasound in diagnosis of intrascrotal metastasis of Wilms' tumor: first case report of a Chinese boy and review of the literature.

A 31-month-old boy with Wilms' tumor (WT), which primarily had originated from the left kidney, was treated with nephrectomy and adjuvant chemotherapy. 2 months after nephrectomy, a left scrotal mass was found at routine follow-up. High-frequency sonography examination revealed an enlarged left testis with a heterogeneous texture and a hypoechoic solid mass in the left scrotum.

[Bone mesenchymal stem cell transplantation for acute myocardial infarction: in vivo tracing with multi-modality molecular imaging].

Objective: To investigate the feasibility of tracking bone mesenchymal stem cell (BMSCs) dual- labeled with polyethylenimine 2k-superparamagnetic iron oxide (PEI2k-SPIO) and Luciferase transplantation for acute myocardial infarction in vivo by using magnetic resonance imaging (MRI) and fluorescence imaging.

Methods: BMSCs/Luciferase was incubated with culture medium containing PEI2k-SPIO for 24 h. Prussian-blue staining and MTT were used to assess the efficacy and safety of labeling with PEI2k-SPIO.

[MR imaging of polyethylenimine-superparamagnetic iron oxide nanoparticle labeled bone marrow mesenchymal stem cells in vitro].

Objective: To explore the optimal concentration of polyethylenimine-superparamagnetic iron oxide (PEI2k-SPIO) particles for labeling bone marrow mesenchymal stem cells (BMSCs) in vitro, then to demonstrate the imaging characteristics of the cells by 7.0-T MR scanner. The lowest cell quantity and the optimal cell quantity detected on MR was observed.

Diagnosis of Schistosomiasis japonica infection coincident with hepatocellular carcinoma by fine-needle aspiration.

Schistosomiasis japonica is not an endemic parasite in Taiwan. Previously, there have been no primarily infected cases reported with the exception of Chinese war veterans who had immigrated from Mainland China. We reported a 79-year-old patient who was diagnosed as having non-B, non-C liver cirrhosis complicated with a 1.
