Evaluating age-and gender-related changes in brain volumes in normal adult using synthetic magnetic resonance imaging.

Objective: Normal aging is associated with brain volume change, and brain segmentation can be performed within an acceptable scan time using synthetic magnetic resonance imaging (MRI). This study aimed to investigate the brain volume changes in healthy adult according to age and gender, and provide age- and gender-specific reference values using synthetic MRI.

Methods: A total of 300 healthy adults (141 males, median age 48; 159 females, median age 50) were underwent synthetic MRI on 3.

Clinical Feasibility of Automated Brain Tissue and Myelin Volumetry of Normal Brian Using Synthetic Magnetic Resonance Imaging With Fast Imaging Protocol: A Single-Center Pilot Study.

Objective: This study aimed to investigate the clinical feasibility of synthetic magnetic resonance imaging (MRI) with fast imaging protocol for automated brain tissue and myelin volumetry in healthy volunteers at 3.0-T MRI.

Methods: Thirty-four healthy volunteers were scanned using synthetic MRI with 3 sets of scan parameters: groups Fast (FAS; 2 minutes, 29 seconds), Routine (ROU; 4 minutes, 7 seconds), and Research (RES; 7 minutes, 46 seconds).

Physical and Mechanical Properties of Novel Porous Ecological Concrete Based on Magnesium Phosphate Cement.

Ecological concrete could reduce the environment impacts of the tremendous construction of infrastructures due to its favorability to plant growth. Nonetheless, the alkalinity of the ecological concrete is usually too high when using ordinary Portland cement (OPC). To solve this problem, the magnesium ammonium phosphate cement (MPC) was used to prepare a novel porous ecological concrete instead of OPC.

Repeat hepatectomy for pediatric recurrent chemotherapy-resistant hepatoblastoma: a report of 18 cases.

Background And Aims: Repeat hepatectomy for adult recurrent hepatocellular carcinoma significantly prolongs the overall survival, but repeat hepatectomy for pediatric recurrent hepatoblastoma (HB) is rarely reported, and the outcomes are warranted to be investigated.

Methods: All patients between May 2015 and December 2020 with recurrent HB after intended surgical cure were retrospectively evaluated. Clinicopathologic features, surgical details and outcomes were analyzed during a median following-up of 24 months after repeat hepatectomy.

The effect of scan parameters on T1, T2 relaxation times measured with multi-dynamic multi-echo sequence: a phantom study.

Multi-Dynamic Multi-Echo (MDME) Sequence is a new method which can acquire various contrast-weighted images using quantitative relaxometric parameters measured from multicontrast images. The purpose of our study was to investigate the effect of scan parameters of MDME Sequence on measured T1, T2 values of phantoms at 3.0 T MRI scanner.
