In this study, a segmented element design using forced-current excitation and a switching circuit is presented. The design provides long FOV when desired and allows flexible FOV switching and power distribution without additional power amplifiers. Different element types and arrangements were explored and a segmented dipole design was chosen as the best design. The segmented dipole was implemented and tested on the bench and with a phantom on a 7T whole body scanner. The switchable mode dipole enabled a large FOV in the long mode and improved ${rm{B}}_{1}^{{rm + }}{rm{/ surd SAR}}_{{rm{max}}}$ efficiency in a smaller FOV in the short mode.

Sangani, Santosh Mathew NaliathA 44-year-old man presented with spontaneous massive hemothorax. Computed tomographic scan revealed thickened and nodular pleura with no evidence of lung tumor. The patient underwent right open total pleurectomy. Histopathologic and immunohistochemical studies of the pleura confirmed poorly differentiated sarcomatoid squamous cell carcinoma of the lung with metastasis to the pleura. The carcinoma was psuedomesothelimatous type because of its presentation as diffuse pleural thicken...

ConclusionsClassic tear-oriented surgical procedure is insufficient for optimal long-term surgical outcomes, mainly regarding aortic dilation. CAR without residual arch vessel tears leads to favorable aortic remodeling in the residual DTA and prevents MAAEs after AIAD repair.

Cox, Sunghee Kim, Michael S. Mulligan, Farhood FarjahBackgroundPrior studies suggest underutilization of invasive mediastinal staging for lung cancer. We hypothesized that The Society of Thoracic Surgeons General Thoracic Surgery Database (STS-GTSD) participants would have higher rates of invasive staging compared with previous reports.MethodsWe conducted a retrospective cohort study (2012 to 2016) of lung cancer patients stag...

The synthesized MoS2-CNF was characterized by scanning electron microscopy (SEM), Raman, X-Ray diffraction (XRD) and Electrochemical impedance technique (EIS). The electrochemical detection of vanillin was successfully conducted in 0.1 M Phosphate Buffer (pH 10) and showed a good linea...
