Value of diffusion-weighted imaging combined with conventional magnetic resonance imaging in the diagnosis of thecomas and their differential diagnosis with adult granulosa cell tumors.

Value of diffusion-weighted imaging combined with conventional magnetic resonance imaging in the diagnosis of thecomas and their differential diagnosis with adult granulosa cell tumors. Acta Radiol. 2019 Feb 18;:284185119830280 Authors: Fang M, Dong J, Zhong Q, Fang X, Chen Y, Wang C, Yan H Abstract BACKGROUND: Magnetic resonance imaging (MRI) is a significant method of identifying ovarian tumors, when combined with certain functional imaging techniques that have been considered to be more accurate. PURPOSE: Our study aims to determine the value of diffusion-weighted imaging (DWI) combined with MRI in the diagnosis of thecomas and adult ovarian granulosa cell tumors (GCTs). MATERIAL AND METHODS: In total, this study included 10 patients with thecomas and nine with adult GCTs. We analyzed the clinical characteristics, conventional MRI, and apparent diffusion coefficient (ADC) values of two groups. The methods of statistical analysis were univariate analysis and the receiver operating characteristic curve. RESULTS: According to T2-weighted imaging of the solid region of the mass, 80% (8/10) of thecomas showed slightly hypointense or mixed signals, but all adult GCTs showed slightly hyperintense signals. The two groups exhibited statistically significant differences ( P

This study included 1249 consecutive patients undergoing either transcatheter aortic valve implantation (TAVI), Mitraclip, left atrial appendage occlusion (LAAO) or paravalvular leak closure (PVLC). Patients were divided into two cohorts based on the degree of probe manipulation required to guide the procedure and the risk of developing a TEE-related complication: low-risk (TAVI, n = 1037) and high-risk (Mitraclip, LAAO and PVLC, n = 212). Patients were further analyzed according to the occurrence of major and minor TEE-related complications.ResultsThe overall incidence of TEE-related complications was ...

In conclusion, we described, for the first time, a case series of nivolumab-induced adrenal insufficiency in patients with mRCC. Our findings may be useful for the accurate diagnosis and the prompt treatment of this condition. In addition, there is a possibility that adrenal insufficiency may be associated with a favorable response to nivolumab in patients with mRCC.

AbstractPurpose of reviewCardiac thrombus formation is a frequent complication of a variety of prevalent diseases. Embolism of cardiac thrombus has the potential to result in significant morbidity and mortality from cerebrovascular and peripheral vascular events.Recent findingsEchocardiography is the most commonly used imaging modality for diagnosing intracardiac thrombus. However, technological advances in computed tomography and magnetic resonance imaging have allowed newer noninvasive modalities to evolve into robust tools for the clinical evaluation of patients suspected of disease.SummaryComplimentary use of these ima...

AbstractPurposeTo retrospectively compare the accuracy of interpretation of initial cervical computerized tomography (CCT) by a non-pediatric radiologist (NPR) versus a pediatric radiologist (PR).MethodsIRB approval and consent waiver were granted to review all injured children from 2010 to 2014 in the trauma registry with CT and magnetic resonance imaging (MRI) of the cervical spine. Patients with negative CCT who subsequently had positive MRI from a single institution comprised the study group. Patients with negative CCT and MRI, matched by age, gender, and severity scores, comprised the control group. The CCTs from both...
