Purpose: This study aimed to elucidate the factors that affect the dynamics of blood D-dimer in ovarian hyperstimulation syndrome (OHSS).

Methods: We retrospectively reviewed medical records from two hospitals and extracted data obtained during assisted reproductive technology and OHSS treatment. Blood D-dimer levels during hospitalization were plotted against body weight.

Purpose: To determine the feasibility of texture analysis of apparent diffusion coefficient (ADC) maps and to assess the performance of texture analysis and ADC to predict histologic grade, parametrial invasion, lymph node metastasis, International Federation of Gynecology and Obstetrics (FIGO) stage, recurrence, and recurrence-free survival (RFS) in patients with cervical carcinoma.

Materials And Methods: This retrospective study included 58 patients with cervical carcinoma who were examined with a 1.5-T MRI system and diffusion-weighted imaging with values of 0 and 1000 sec/mm.

The subcutaneous transplantation of microencapsulated islets has been extensively studied as a therapeutic approach for type I diabetes. However, due to the lower vascular density and strong inflammatory response in the subcutaneous area, there have been few reports of successfully normalized blood glucose levels. To address this issue, we developed mosaic-like aggregates comprised of mesenchymal stem cells (MSCs) and recombinant peptide pieces called MSC CellSaics, which provide a continuous release of angiogenic factors and anti-inflammatory cytokines.

Objective: The aim of the study was to assess non-Gaussian diffusion kurtosis imaging (DKI)'s usefulness as a noninvasive method to evaluate tumor invasion depth, histological grade, and lymph node metastasis in cervical carcinoma (CC) patients.

Methods: Twenty-two consecutive patients with histologically confirmed CC were examined by 1.5-T MRI and non-Gaussian DKI with 4 b values of 0, 500, 1000, and 2000 s/mm2.

The authors investigated the usefulness of diffusion-tensor imaging (DTI) for evaluating tumor invasion depth, histologic grade, and lymph node metastasis in patients with cervical carcinoma (CC). Fifteen consecutive patients with histologically confirmed CC underwent 1.5-T magnetic resonance imaging and DTI.

Purpose: To determine the feasibility of texture analysis (TA) of apparent diffusion coefficient (ADC) maps for predicting histologic grade (HG) and recurrence-free survival (RFS) in patients with endometrial carcinoma (EMC).

Materials And Methods: One hundred twenty-one patients with EMC were examined by using a 1.5-T MRI system and diffusion-weighted imaging (DWI) with values of 0 and 1000 sec/mm.

Purpose: In this study, we aimed to determine the usefulness of diffusion kurtosis imaging (DKI) as a noninvasive method for the evaluation of tumor invasion depth, histological grade, and lymph node metastasis in patients with endometrial carcinoma (EMC).

Materials And Methods: Our institutional review board approved this retrospective study and waived informed consent. In total, 24 patients suspected of having EMC were examined by a 1.

Background: Although the prognosis of endometrial carcinoma (EMC) patients strictly depends on tumor invasion depth and its histologic grade, accurate preoperative assessment of these prognostic factors is often difficult.

Purpose: To determine the usefulness of diffusion-tensor imaging (DTI) as a noninvasive method for evaluating tumor invasion depth and its histologic grade in patients with EMC.

Study Type: Prospective.

Objective: To evaluate the role of follow-up after curative treatment in endometrial carcinoma, we determined predictive factors for prolonged survival after recurrence.

Methods: We retrospectively studied patients with endometrioid endometrial carcinoma who had a follow-up appointment consisting of pelvic examination, vaginal cytology, imaging and CA-125 measurements and who developed recurrence. Possible prognostic factors were evaluated by univariate and multivariate analyses.
