This ligament was fenestrated with separate anterior and posterior fibers. The anterior fibers were more proximal, and the posterior fibers were more distal, attaching to the fibula in close proximity to the PITFL. Coronal images best depicted the course of the IOL.

Conclusion: Oblique imaging planes parallel to the long axis of the ligament better display the normal anatomy of the tibiofibular syndesmotic ligaments when compared with standard imaging planes. (C) RSNA, 2010″
“We report on the electro-optic and dielectric properties of optical switching devices

based on poly(3,4-ethylene dioxythiophene):polystyrene sulfonate (PEDOT:PSS) electrodes sandwiching a polymer-dispersed liquid crystal (PDLC) layer. We demonstrate that the frequency

dependence of the driving AC220 concentration electric field on the optical properties of these devices allows the fabrication of flexible bandpass light modulators. Selleck FK866 The (PEDOT:PSS) electrodes are characterized using UV-Vis, scanning electron microscopy, Raman, conductive atomic force microscopy, and linear four probe technique. The PEDOT:PSS/PDLC-based displays exhibit similar electro-optical performances to those of ITO-based devices. In addition, it can function as a bandpass light modulator. This behavior resulted from depolarization fields (Maxwell-Wagner-Sillars effects) occurring (i) at the polymer/LC interface (low frequency) and (ii) between nanometer-sized conductive PEDOT-rich domains and poorly conductive PSS-rich areas present in the bulk and at the surface of the electrode (high frequency).

“Purpose: To image cartilage- bone interfaces in naturally occurring and experimentally prepared human cartilage-bone specimens at 3 T by using ultrashort echo time (TE) (UTE) and conventional pulse sequences to (a) determine the appearance of the signal intensity patterns and (b) identify the structures contributing to signal intensity on the UTE MR images.

Materials and Methods: This study was exempted by the institutional review board, and informed consent was not required. Five

cadaveric ( mean age, 86 years +/- 4) patellae were imaged by using proton density-weighted fat-suppressed find more ( repetition time msec/TE msec, 2300/34), T1-weighted (700/10), and UTE (300/0.008, 6.6, with or without dual-inversion preparations at inversion time 1 = 135 msec and inversion time 2 = 95 msec) sequences. The UTE images were compared with proton density-weighted fat-suppressed and T1-weighted images and were evaluated by two radiologists. To identify the sources of signal on the UTE images, samples including specific combinations of tissues (uncalcified cartilage [UCC] only, calcified cartilage [CC] and subchondral bone [bone] [CC/bone], bone only; and UCC, CC, and bone [UCC/CC/bone]) were prepared and imaged by using the UTE sequence.
