Analysis of enhanced CT imaging signs and clinicopathological prognostic factors in hepatoid adenocarcinoma of stomach patients with radical surgery: a retrospective study.

Background: To investigate the association between CT signs and clinicopathological features and disease recurrence in patients with hepatoid adenocarcinoma of stomach (HAS).

Methods: Forty nine HAS patients undergoing radical surgery were retrospectively collected. Association between CT and clinicopathological features and disease recurrence was analyzed.

Feasibility study of low tube voltage (80 kVp) coronary CT angiography combined with contrast medium reduction using iterative model reconstruction (IMR) on standard BMI patients.

Objective: To investigate the feasibility of low-tube-voltage (80 kVp) coronary CT angiography (CCTA) combined with contrast medium (CM) reduction and iterative model reconstruction (IMR) on patients with standard body mass index compared with clinical routine protocol.

Methods: Retrospectively gated helical CCTA scans were acquired using a 256-slice multi-slice CT (Brilliance iCT; Philips Healthcare, Cleveland, OH) on 94 patients with standard body mass index (20-25 kg m(-2)) who were randomly assigned into 2 groups. The scan protocol for Group 1 was 100 kVp and 600 mAs with 70 ml CM at an injection rate of 4.

Correlation of creatine kinase with patency of stents using coronary computed tomography angiography.

Objective: To explore the potential correlation between creatine kinase and the long-term patency of coronary drug eluting stents.

Methods: The clinical data of 74 patients who had undergone coronary computed tomography angiography after drug eluting stents implantation were retrospecpectively analyzed. Based on the computed tomography angiography findings,these patients were divided into patency group and non-patency group.

CT characteristics and pathological implications of early stage (T1N0M0) lung adenocarcinoma with pure ground-glass opacity.

Objectives: To analyze the CT characteristics and pathological classification of early lung adenocarcinoma (T1N0M0) with pure ground-glass opacity (pGGO).

Methods: Ninety-four lesions with pGGO on CT in 88 patients with T1N0M0 lung adenocarcinoma were selected from January 2010 to December 2012. All lesions were confirmed by pathology.

Predictive value of apolipoprotein for coronary atherosclerosis in asymptomatic non-diabetic population.

Objective: To explore the potential correlation between apolipoprotein (Apo) levels and coronary atherosclerosis and investigate its predictive value for coronary artery lesions in asymptomatic population without diabetes.

Methods: We performed a retrospective analysis of data collected from 401 asymptomatic patients who took health check-ups. They were divided into atherosclerosis group (n=224)and control group (n=177) based on the outcome of CT angiography and blood biochemical findings.

Value of coronary computed tomography angiography in ruling out coronary artery disease before intermediate- and high-risk non-cardiac surgery.

Objective: To assess the value of preoperative coronary computed tomographic angiography (CCTA) in the detection of coronary artery disease (CAD) in patients planned to undergo non-cardiac surgery at intermediate or high risk to avoid unnecessary invasive coronary angiography (ICA).

Methods: The study protocol was approved by our institutional review board and informed consent was given. In this prospective study, 157 consecutive patients who underwent CCTA before undergoing non-cardiac surgery at intermediate or high risk was involved.

[Clinical value of double respiratory navigator-gated high-resolution black-blood coronary artery wall magnetic resonance imaging].

Objective: To explore the value of phase ordering with automatic window selection(PAWS)and simultaneous multiple volume(SMV)algorithm double respiratory navigator-gated two-dimensional(2DNAV)dual inversion recovery(DIR)fast spin echo(FSE)high-resolution black-blood coronary artery wall magnetic resonance imaging(MRI)and evaluate its advantages and limitations.

Methods: PAWS and SMV 2DNAV DIR FSE high-resolution black-blood MRI was performed in 21 healthy volunteers. The images were evaluated qualitatively by using four grades(grade 0can not evaluate;grade 1bad;grade 2good;grade 3perfect).

[Values of computed tomography angiogram in non-cardiac surgery planning and cardiac risk assessment of coronary atherosclerosis during perioperative period].

Objective: To explore the values of detecting coronary atherosclerosis by computed tomography angiogram (CTA) on non-cardiac surgery planning and cardiac risk assessment of coronary atherosclerosis during perioperative period.

Methods: A total of 89 patients with suspected coronary heart disease (CHD) scheduled for non-cardiac surgery underwent coronary CTA to evaluate luminal stenosis and calculate calcification score. There were 56 males and 33 females with a mean age of 65.

Diagnostic accuracy and its affecting factors of dual-source CT for assessment of coronary stents patency and in-stent restenosis.

Background: In-stent restenosis is a common complication after stent implantation. However, the assessment of stent lumen in computed tomography (CT) coronary angiography is limited by multiple factors. Our study aimed to evaluate the accuracy and the suspected affecting factors in diagnosing coronary in-stent restenosis by dual-source CT (DSCT) compared with coronary angiography.

[Volumetric measurement of pericardial and intrathoracic adipose tissues using coronary computed tomography angiography in patients with coronary heart disease].

Objective: To investigate the feasibility of volumetric measurement of pericardial adipose tissue (PAT) and intrathoracic adipose tissue (IAT) using coronary computed tomography angiography (CTA), and explore the characteristics of PAT and IAT distribution.

Methods: The CTA images of 109 patients (aged 59.1∓11.

Hemodynamics model of fluid-solid interaction in internal carotid artery aneurysms.

The objective of this study is to present a relatively simple method to reconstruct cerebral aneurysms as 3D numerical grids. The method accurately duplicates the geometry to provide computer simulations of the blood flow. Initial images were obtained by using CT angiography and 3D digital subtraction angiography in DICOM format.
