Correlation between C-reactive Protein and Morphology of Aortic Intramural Hematoma on CT Angiography.

To investigate the morphologic characteristics of intramural hematoma (IMH) on CT angiography (CTA), and evaluate the possible correlation of serum C-reactive protein (CRP) with morphologic characteristics of IMH. Forty-two patients who were initially diagnosed as IMH by aortic CTA and also had serum CRP examination on the same day of CTA were enrolled in this retrospective study, including 30 males and 12 females, with the mean age of 61 ± 14 years old. The volumetric CT data were retrospectively processed and analyzed on post-processing workstation.

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.

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.

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.

[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.
