Prognostic value of computed tomography derived skeletal muscle mass index in lung cancer: A meta-analysis.

Background: The prognostic role of the skeletal muscle mass index (SMI) derived from computed tomography (CT) imaging been well verified in several types of cancers. However, whether the SMI could serve as a reliable and valuable predictor of long-term survival in lung cancer patients remains unclear.

Aim: To identify the prognostic value of the CT-derived SMI in lung cancer patients.

Prognostic value of ground glass opacity on computed tomography in pathological stage I pulmonary adenocarcinoma: A meta-analysis.

Background: The clinical role of ground glass opacity (GGO) on computed tomography (CT) in stage I pulmonary adenocarcinoma patients currently remains unclear.

Aim: To explore the prognostic value of GGO on CT in lung adenocarcinoma patients who were pathologically diagnosed with tumor-node-metastasis stage I.

Methods: A comprehensive and systematic search was conducted through the PubMed, EMBASE and Web of Science databases up to April 3, 2021.

[Application Value of CT Metal Artifact Correction Technology (MAC ) in CT Review after Total Hip Replacement].

Objective: To evaluate the application value of CT metal artifact correction technology (MAC ) in CT review after total hip replacement.

Methods: A total of 72 patients who underwent CT re-examination after total hip replacement from December 2018 to March 2020 were enrolled, and the original data were reconstructed by filter backup projection （FBP） and MAC. Select three identical levels in the two sets of reconstructed images and place the same ROI.

[Application Value of Motion-correction Phase Sensitive Inversion Recovery (MOCO-PSIR) to Evaluate Myocardial Fibrosis in Patients with Heart Failure Caused by Dilated Cardiomyopathy].

Objective: To study the application value of motion-correction phase sensitive inversion recovery (MOCO-PSIR) to evaluate myocardial fibrosis in the patients with heart failure caused by dilated cardiomyopathy (DCM).

Methods: A prospective study included 60 patients who underwent cardiac MRI enhanced scan from June 2017 to November 2018, including 38 patients who were clinically diagnosed with DCM and 22 patients in the normal control group. All patients were scanned with three late gadolinium enhancement (LGE) sequences: segmented-PSIR, single-shot-PSIR, MOCO-PSIR at the same time.

[Image quality adapted thoracic diameters in CT coronary artery imaging].

Objective: To evaluate the correlation between image quality and thoracic diameters, anteroposterior diameter (AP) and right-left diameter (RL) for the optimization of reducing radiation dose in coronary artery imaging with Dual-source CT.

Methods: 118 patients underwent CT coronary artery imaging (CTCA) were divided into two groups (A and B) according to body mass index (BMI). There were 58 patients in group A with BMI values > or = 25 kg/m2 and < 30 kg/m2; and 60 patients in group B with BMI values < 25 kg/m2.

[The value of split-bolus 2-phase with virtual non-enhanced scan in CT urography].

Objective: To investigate the value of split-bolus 2-phase with virtual non-enhanced scan in CT urography.

Methods: Eighty (80) patients with urinary obstruction were divided into two groups, group A was traditional CT urography scan, group B was split-bolus 2-phase with virtual non-enhanced scan. The scan sequence of group A included conventional scan first, then enhanced scan in arterial phase, parenchyma phase and excretion delayed phase after the injection of 100 mL contrast agent.
