The ability to visualize whole-brain vasculature is important for quantitative in vivo investigation of vascular malfunctions cerebral small vessel diseases, including cancer, stroke and neurodegeneration. Transverse relaxation-based ΔR2 ΔR2* MR angiography (MRA) provides improved vessel–tissue contrast animal deep brain with the aid intravascular agents; however, it susceptible orientation dependence, air–tissue interface artifacts size overestimation. Dual-mode MRA acquisition...
Abstract Background This study aimed to demonstrate the efficacy of erbium, chromium-doped:yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser-assisted nonsurgical periodontal therapy in periodontitis patients during 8 weeks healing. Methods A split-mouth, single-blinded, randomized controlled clinical trial was conducted on 12 diagnosed with stage III/IV had a minimum two teeth probing pocket depth (PPD) > 5 mm at least quadrants. Upon randomization, each quadrant assigned for...
Purpose: In PACS (Picture Archiving and Communications System) environment, the export of DICOM portable data for imaging (PDI) has been increased in accordance with demands patents referring to other hospitals. The PDI currently stored a CD (Compact Disk) causes problems retrieve archive occasionally environment destination hospital although it was created under obeying standards. Method Materials: validation toolkit developed verifying sets complying standard PS 3.3 improve compatibility...
Purpose: We quantitatively assessed the spatial resolution, contrast, and image uniformity of laser CCD film digitizers in PACS applications for our Hospital. Method Materials: The modulation transfer function(MTF) was measured by using created chessboard‐pattern test to obtain edge spread function(ESF) both horizontal vertical scanning direction. line function(LSF) obtained from ESF results. A step wedge order evaluate contrast characteristics. Optical densities(ODs) each step‐wedge region...
