This paper presents a solution to satisfy the increasing requirements for secure medical image transmission and storage over public networks. The proposed scheme can simultaneously encrypt compress using compressive sensing (CS) pixel swapping based permutation approach. In CS phase, plain is compressed encrypted by chaos-based Bernoulli measurement matrix, which generated under control of introduced Chebyshev map. quantized measurements are then permutation-diffusion type chaotic cipher...
Nowadays, the increasing demand for telemedicine services has raised interest in real-time medical image protection literatures. In this paper, we evaluate security of an efficient and secure scheme recently proposed (Fu et al., 2013). It is found that can be successfully broken by launching chosen-plaintext attacks. Improvement subsequently developed promoting efficiency performance. Extensive analyses experimental results both indicate improved well address flaws advance speed performance...
Abstract Background and purpose Malignant brain edema (MBE) occurring after mechanical thrombectomy (MT) in acute ischemic stroke (AIS) could lead to severe disability mortality. We aimed investigate the incidence, predictors, clinical outcomes of MBE patients with AIS MT. Methods The imaging data 155 anterior circulation MT were studied. Standard non-contrast CT was used evaluate baseline characteristics at admission. Clinical measured using 90-day modified Rankin Scale (mRS) score. Based...
Abstract To predict massive cerebral infarction (MCI) occurrence after anterior circulation occlusion (ACO) by cASPECTS-CTA-CS (combined ASPECTS and CTA-CS). Of 185 patients with the ACO, their collateral scores from CT angiography (CTA) images in two groups (MCI non-MCI) were evaluated using Alberta Stroke Program Early Score (ASPECTS) score (CTA-CS) approaches. The was validated internally bootstrap sampling method 1000 repetitions compared to CTA-CS. Receiver-operating characteristic...
Adherent perinephric fat (APF) is evaluated preoperatively with the Mayo adhesive probability (MAP) scoring system using conventional single-form computed tomography (CT) images. An objective or quantitative indicator for predicting APF urgently needed clinical application.A total of 150 patients renal tumours who underwent laparoscopic partial nephrectomy (LPN) were retrospectively enrolled and divided into group (n=100) non-APF (n=50) according to surgical results. All a contrast-enhanced...
Adherent perinephric fat (APF) is evaluated preoperatively with the Mayo adhesive probability (MAP) scoring system using conventional single form computed tomography (CT) images. An objective or quantitative indicator for predicting APF urgently needed clinical application.Data obtained from 150 renal tumor patients partial nephrectomy (PN) were used in present study. Patients divided into two groups based on surgical results: an group (n=100) and a non-APF (n=50). All had contrast-enhanced...
The paper proposes a mathematical model about the relationship between curvature radius changes of interventricular septal configuration and pressure difference left right ventricular based on Young-Laplace model. method noninvasive detection is discussed. In this which can simulate deformation in differential designed produced. After scanning by CT, boundary extracted calculated. Software ANSYS used to septum verify experiment. Then ventricle was established Hooke's law combined with...
Objective To explore the feasibility of 100 KVP on liver tri-phase enhancement scan. Methods A total 60 patients whose BMI from 20 - 25 kg/m2 with suspected disease underwent enhanced CT scans divided into two groups randomly, and each group includes 30 cases. Low dose were scanned auto modulation tube current(peak current 600 mA). image raw data sets reconstructed ASIR composite at 50%. Normal 120 250 mA. FBP. Contrast medium injection rate volume personalized by patients' weight...
Abstract To predict massive cerebral infarction (MCI) occurrence after anterior circulation occlusion (ACO) by cASPECTS-CTA-CS (combined ASPECTS and CTA-CS). Of 112 patients with the ACO, their collateral scores from CT angiography (CTA) images in two groups (MCI non-MCI) were evaluated using Alberta Stroke Program Early Score (ASPECTS) score (CTA-CS) approaches. Receiver-operating characteristic curve (ROC), clinical impact (CIC), decision analysis (DCA) strategies used to assess...
Objective To investigate enhanced MRI and PET/CT value in the diagnosis pseudomyxoma peritonei(PMP)and distinguishing benign malignant. Methods A retrospective study was performed on 46 PMP patients who were admitted from January 2011 to June 2016.All received preoperative scans PET/CT.The of postoperative pathological or clinical comprehensive evaluation standard.To compare two methods PMP′s malignant. Results Among patients, 34 cases diagnosed with 12 non PMP.The sensitivity...
