11 By contrast, a positive impact of very low-dose radiation has been reported on distal femur cancellous bone in C57BL/6J adult mice who were exposed to collimated head-only iron-ion 56Fe dose with a collimator interposed between the beam and the animals, resulting in a 0.04 Gy ...
Feasibility of Low Volume of High-Concentration Iodinated Contrast Medium With 70 kVp Tube Voltage on High-Pitch Dual-Source Computed Tomography Angiography in Children With Congenital Heart Diseasecongenital heart diseasedual-source CTcontrast medium...
In this work, we present our laboratory X-ray Talbot- Lau interferometry setup operating at 40 kVp and describe how we achieve the high sensitivity yet unrivalled by any other laboratory X-ray phase-contrast technique. We provide the angular sensitivity expressed via the minimum resolvable ...
Figure 1. Radiographic image of a high contrast, resolution target taken at 77 kVp, 2.5 mAs. Initial signal level equals 3.4 Me. In Figure 1 we show a radiographic image of a high contrast, resolution target, taken at a 2.5 mAs, 77 kVp dose which produces approximately 3.4 Me of charge...
Radiation was delivered using a Philips RT-250 200 kVp X-ray unit (Philips, MA, USA) (12.5 mA; half-value layer, 1.0 mm Cu) at a dose rate of 140 cGy/min. The whole brain was locally irradiated with a single dose of 60 Gy. After irradiation, the rats were returned to their ...
In this study, an inter-fraction organ deformation simulation framework for the locally advanced cervical cancer (LACC), which considers the anatomical fle
It will also review the three most commonly used types of dual-energy images: “workhorse” 120kVp surrogate images (including blended polychromatic and 70 keV monochromatic), high contrast images (e.g., low energy monochromatic and iodine material decomposition images), and virtual unenhanced ...
A previously developed algorithm was used to determine CAC scores on the low-dose, non-ECG-triggered, attenuation correction CT (LDACT) images acquired during MPI34. Scans were acquired with 120 kVp on a hybrid scanner (Biograph CT Flow 64-Slice scanner, Siemens Healthcare, Knowxville, Tennes...
Isocitrate dehydrogenase 2 (IDH2) is an NADP+-dependent enzyme that catalyzes the oxidative decarboxylation of isocitrate to α-ketoglutarate in the mitochondrial matrix, and is critical for the production of NADPH to limit the accumulation of mitochondr
