CT and histopathologic characteristics of lung adenocarcinoma with pure ground-glass nodules 10 mm or less in diameter.

Objective: To evaluate CT and histopathologic features of lung adenocarcinoma with pure ground-glass nodule (pGGN) ≤10 mm in diameter.

Methods: CT appearances of 148 patients (150 lesions) who underwent curative resection of lung adenocarcinoma with pGGN ≤10 mm (25 atypical adenomatous hyperplasias, 42 adenocarcinoma in situs, 38 minimally invasive adenocarcinomas, and 45 invasive pulmonary adenocarcinomas) were analyzed for lesion size, density, bubble-like sign, air bronchogram, vessel changes, margin, and tumour-lung interface. CT characteristics were compared among different histopathologic subtypes.

Value of Baseline Clinical and CT Characteristics for Predicting the Progression of Persistent Pure Ground-glass Nodule 10 mm or Less in Diameter.

Objective To explore the risk factors of the progression of persistent pure ground-glass nodule (pGGN) and make the risk stratification for pGGN 10 mm or less in diameter. Methods From June 2008 to April 2015,100 patients (108 lesions) with persistent pGGN≤10 mm in diameter were included in this study. Patients were followed up at least 1 year using thin-section computed tomography (CT).

Correlations between pathologic subtypes/immunohistochemical implication and CT characteristics of lung adenocarcinoma ≤ 1 cm with ground-glass opacity.

Objective: To discuss the correlation of pathologic subtypes and immunohistochemical implication with CT features of lung adenocarcinoma 1 cm or less in diameter with focal ground-glass opacity (fGGO).

Methods: CT appearances of 59 patients who underwent curative resection of lung adenocarcinoma ≤ 1 cm with fGGO were analyzed in terms of lesion location, size, density, shape (round, oval, polygonal, irregular), margin (smooth, lobular, spiculated, lobular and spiculated), bubble-like sign, air bronchogram, pleural tag, and tumor-lung interface. Histopathologic subtypes were classified according to International Association for the Study of Lung Cancer/ American Thoracic Society/European Respiratory Society classification of lung adenocarcinoma.

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.

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.

[Association of myocardial bridge of the left anterior descending coronary artery with coronary atherosclerotic stenosis in the segment proximal to the site of bridge].

Objective: To investigate whether myocardial bridging (MB) is independently associated with coronary atherosclerosis proximal to MB in the left anterior descending coronary artery (LAD) identified by computed tomographic coronary angiography (CCTA).

Methods: From March 2011 to December 2012, patients (n=9 862) with suspected coronary disease underwent CCTA using dual-source CT scanner. The baseline clinical characteristics (age, gender, smoking history, presence of hypertension, dyslipidemia, diabetes mellitus, family history of heart attack, and body mass index) and the results of CCTA were reviewed.

MR imaging of the spine at 3.0T with T2-weighted IDEAL fast recovery fast spin-echo technique.

Objective: To compare the iterative decomposition of water and fat with echo asymmetry and the least-squares estimation (IDEAL) method with a fat-saturated T2-weighted (T2W) fast recovery fast spin-echo (FRFSE) imaging of the spine.

Materials And Methods: Images acquired at 3.0 Tesla (T) in 35 patients with different spine lesions using fat-saturated T2W FRFSE imaging were compared with T2W IDEAL FRFSE images.

[Analysis of liver function index and clinical characters in 122 patients with acute hepatitis E virus coinfection with other hepatitis virus].

Objective: To compare the liver function index and clinical characters in 122 patients with acute hepatitis E virus overlapping with other infection.

Methods: The liver function index and clinical characters of 122 patients with acute hepatitis E virus overlapping infection and 40 patients with acute hepatitis E were retrospectively analyzed.

Results: No significant differences of ALT, AST, TBIL, DBIL were found between acute hepatitis E groups and overlapping infection hepatitis A or hepatitis B (P > 0.

[Study on the overall anatomical features and clinical value of lumbar nerve root, plexus and branches in CT reconstruction].

Objective: To identify the overall anatomical characteristics and the clinical value of the lumbar nerves under CT multiplanar reconstruction.

Methods: Fifty normal subjects and 30 patients with LN diseases (51 sides) were selected, including 10 patients with lumber intervertebral disk hernia, eight patients with spinal stenosis, 5 patients with spondylolisthesis, 1 patient with tethered cord syndrome, 1 patient with lumbar scoliosis, and 5 patients with spinal trauma The 16-slice helical CT (Light Speed, GE Company) was used for scanning the lumbar vertebra with multiplanar reconstruction in Workstation (ADW4.1) with UNIX System in DICOM format.
