Natural adaptation to femoral artery occlusion in animals by collateral growth restores only approximately 35% of adenosine-recruitable maximal conductance (C(max)) probably because initially elevated fluid shear stress (FSS) quickly normalizes. We tested the hypothesis whether this deficit can be mended artificially increasing FSS or anatomical restraints prevent complete restitution. chronically increased draining flow directly into venous system a side-to-side anastomosis between distal...
Acute Pulmonary Embolism to the Subsegmental Level: Diagnostic Accuracy of Three MRI Techniques Compared with 16-MDCTAlexander Kluge1, Wolfgang Luboldt2 and Georg Bachmann1Audio Available | Share
In a technical development study approved by the institutional ethics committee, feasibility of fast diffusion-weighted imaging as replacement for conventional magnetic resonance (MR) sequences (short inversion time recovery [STIR] and T1-weighted spin echo [SE]) positron emission tomography (PET)/computed (CT) in detection skeletal metastases from prostate cancer was evaluated. MR carbon 11 ((11)C) choline PET/CT data consecutive patients with bone were analyzed. Diffusion-weighted appears...
Investigating focal cerebral ischemia requires animal models that are relevant to human stroke. Complications and side effects common among these models. The present study describes potential pitfalls in 3 techniques for middle artery occlusion (MCAO) rats using magnetic resonance imaging (MRI) angiography (MRA).Rats were subjected temporary MCAO 90 minutes the suture technique (group I; n=10) or permanent II; macrosphere III; n=10). Clinical evaluation was performed after hours 24 hours....
Cardiac surgery carries a high risk of neurological complications; therefore, these patients would be an appropriate target population for neuroprotective strategies. In this study, we evaluated postoperative diffusion-weighted imaging (DWI) as potential surrogate marker brain embolism and its relationship to neurobiochemical markers injury.Of total 45 consecutive undergoing aortic valve replacement, 37 completed preoperative MRI. At the time MRI studies, serum S100beta neuron-specific...
The purpose of this study was to prospectively assess the feasibility and quality combined MRI examinations consisting thoracic for suspected pulmonary embolism (PE) MR venography deep vein thrombosis (DVT), diagnostic yield a examination detecting thromboembolism compared with each component alone, retrospectively concordance duplex sonography venography.Two hundred twenty-one consecutive patients (119 men, 102 women; mean age, 51 years; range, 31-86 years) PE were examined using...
Pulmonary vein stenosis (PVS) is a potential complication of pulmonary isolation (PVI) using radiofrequency energy. The aim our study was the evaluation severity and long-term outcome primary angioplasty with stenting for PVS.Twelve patients 15 PVS (greater than 70% stenosis) were prospectively evaluated. Primary dilation performed because clinical symptoms (10 patients) and/or lung perfusion scans showed significant defect (11 patients). Magnetic resonance imaging before, directly after,...
The long term goal of the CERN Experimental Physics Department R&D on monolithic sensors is development sub-100nm CMOS for high energy physics. first technology selected TPSCo 65nm imaging technology. A submission MLR1 included several small test chips with sensor and circuit prototypes transistor structures. One main questions to be addressed was how optimize in presence significant in-pixel circuitry. In this paper optimization described as well experimental results from run confirming its...
Abstract With the next upgrade of ALICE inner tracking system (ITS3) as its primary focus, a set small MAPS test structures have been developed in 65 nm TPSCo CMOS process. The CE-65 focuses on characterisation analogue charge collection properties this technology. latest iteration, CE-65v2, was produced different processes (Standard, with low-dose n-type blanket, and blanket gap between pixels), pixel pitches (15, 18, 22.5 µm) arrangements (square or staggered). comparatively large array...
This paper presents the design of a front-end circuit for monolithic active pixel sensors. The operates with sensor featuring small, low-capacitance (< 2 fF) collection electrode and is integrated in DPTS chip, proof-of-principle prototype 1.5 mm × including matrix 32 pixels pitch 15 μm. chip implemented 65 nm imaging technology from Tower Partners Semiconductor Co. foundry was developed framework EP-R&D program at CERN to explore this particle detection. has an area 42 μm <sup...
In the future LHC experiments, some data acquisition and trigger links will be based on Gbit/s optical fiber networks. this paper, a configurable radiation tolerant serializer (GOL) is presented that addresses high-energy physics experiments requirements. The device can operate in four different modes are combination of two transmission protocols rates (0.8 1.6 Gbit/s). ASIC may used as transmitter that, otherwise, use only commercial components. encoding schemes supported CIMT (G-Link)...
Abstract A series of monolithic active pixel sensor prototypes (APTS chips) were manufactured in the TPSCo 65 nm CMOS imaging process framework CERN-EP R&D on sensors and ALICE ITS3 upgrade project. Each APTS chip contains a 4 × matrix with fast analog outputs buffered to individual pads. To explore characteristics, various pitches (10 µm–25 µm), geometries reverse biasing schemes included. Prototypes are fully functional detailed characterization ongoing. The design will be presented...
Gbit/s data transmission links will be used in several LHC detectors trigger and acquisition systems. In these experiments, the transmitters subject to high radiation doses over lifetime of experiments. this work, a tolerant transmitter ASIC is described. The IC supports two standard protocols, G-link Gbit-Ethernet, sustains at both 800 Mbit/s 1.6 Gbit/s. was implemented mainstream 0.25 /spl mu/m CMOS technology employing layout practices.
