X-ray computed tomography (CT) imaging can produce three-dimensional and high-resolution anatomical images without invasion, which is extremely useful for disease diagnosis in the clinic. However, its applications are still severely limited by the intrinsic drawbacks of contrast media (mainly iodinated water-soluble molecules), such as rapid clearance, serious toxicity, inefficient targetability and poor sensitivity. Due to their high biocompatibility, flexibility in preparation and modification and simplicity for drug loading, organic nanoparticles (NPs), including liposomes, nanoemulsions, micelles, polymersomes, dendrimers, polymer conjugates and polymeric particles, have demonstrated tremendous potential for use in the efficient delivery of iodinated contrast media (ICMs). Herein, we comprehensively summarized the strategies and applications of organic NPs, especially polymer-based NPs, for the delivery of ICMs in CT imaging. We mainly focused on the use of polymeric nanoplatforms to prolong circulation time, reduce toxicity and enhance the targetability of ICMs. The emergence of some new technologies, such as theragnostic NPs and multimodal imaging and their clinical translations, are also discussed.

Introduction: No standard quantitative imaging approach exists to evaluate volumetric changes in tissue perfusion in the lower extremities following medical treatment. In this study, we develop and apply a three-dimensional model of the foot for evaluation of regional changes in perfusion following revascularization in diabetic patients with non-healing foot ulcers. We hypothesize that SPECT/CT imaging will permit quantification of regional improvements in tissue perfusion in territories of the foot that contain non-healing ulcers, allowing for quantitative evaluation of revascularization procedures. Methods: Resting 99m Tc-tetrofosmin (dose 554.0 ± 26.6 MBq) SPECT/CT was performed on diabetic patients (n=5; 64 ± 15 yrs) before and 1-3 days after lower extremity angioplasty and/or stenting. The CT attenuation scans were used to define five regions of interest (ROIs) in the foot and for quantification of relative changes in regional perfusion with 99m Tc-tetrofosmin SPECT (Fig. 1A). Radiotracer uptake for each ROI was normalized to injected dose and ROI volume, and expressed as a percent change from baseline value. Results: SPECT/CT imaging demonstrated quantitative improvements in regional tissue perfusion in ROIs containing non-healing ulcers for 4 out of 5 patients following revascularization (Fig. 1B). The single patient demonstrating a negative response (11.7% decrease in perfusion) underwent eventual amputation. Conclusions: Early changes in tissue perfusion following revascularization can be non-invasively evaluated in specific vascular territories of the foot using SPECT/CT imaging and may be associated with wound healing and limb salvage outcomes.

Abstract The construction of quality model for outcome-based education (OBE) Education Mode is an important foundation to guarantee the effective implementation of OBE education reform. The quality model for OBE Education Mode is constructed by layers in this paper according to the reverse design characteristics of OBE Education Mode, which is centred on the students’ learning outcome quality, and in accordance with the closed-loop control requirements for quality. Based on the design of the quality monitoring mechanism, the achievement evaluation mechanism and the feedback and improvement mechanism, a three-dimensional, linked and whole-process quality model system is formed with daily monitoring as the means, the achievement evaluation as the core, the feedback of evaluation result as the focus and the continuous improvement as the goal. Finally, the suggestions are made at the level of implementation to further guarantee the operation effect of the quality model, and so as to offer the important assurance for overall promotion of OBE Education Mode reform.
