Cardiac Computed Tomography-Derived Left Atrial Strain and Volume in Pediatric Patients With Congenital Heart Disease: A Comparative Analysis With Transthoracic Echocardiography.

Purpose: This study aimed at exploring the feasibility and reproducibility of CCT for the measurement of Left Atrial (LA) strain and volume compared with transthoracic echocardiography (TTE) in pediatric patients with congenital heart disease (CHD).

Materials And Methods: The present study included 43 postoperative patients with CHD (7.39 ± 3.

Foot and ankle reconstruction using the lateral supramalleolar flap versus the anterolateral thigh flap in the elderly: A comparative study.

The purpose of this study was to compare the reconstructive outcomes of soft-tissue defects around the foot and ankle with anterolateral thigh (ALT) flap or lateral supramalleolar (LSM) flap and attempt to provide an optimal strategy for elderly patients. A retrospective review of all continuous patients with foot and ankle reconstruction using different flaps from October of 2010 and October of 2020 was performed. Based on the flap types, the patients were divided into two groups: ALT flap group (n = 50) and LSM flap group (n = 46).

Feasibility of Cardiac Computed Tomography for the Evaluation of Ventricular Function in Postoperative Children With Congenital Heart Disease: Comparison With Cardiac Magnetic Resonance Imaging.

Objective: We explored the feasibility of cardiac computed tomography (CCT) to evaluate postoperative ventricular function in children with congenital heart disease (CHD) and evaluated the accuracy and reproducibility of CCT using cardiac magnetic resonance (CMR) as a reference.

Methods: Thirty-two postoperative children with CHD (20 boys and 12 girls) who underwent CMR and CCT were enrolled. Left and right ventricular ejection fraction, end-diastolic volume, end-systolic volume, stroke volume, and cardiac index were measured using cardiac function analysis software.

Feasibility of using a non-sedation protocol for evaluation of neonatal congenital heart disease by using a 16-cm wide-detector computed tomography with a low radiation dose: preliminary experience from a single pediatric medical center.

The aim of this study is to explore the feasibility of using a non-sedation protocol for the evaluation of neonatal congenital heart disease by using 16-cm wide-detector CT with a low radiation dose. Thirty-four neonates (group 1) were enrolled to undergo cardiac CT without sedation between August 2018 and March 2019. The control group (group 2) comprising 20 inpatient neonates was sedated.

Diagnostic accuracy of multi-slice computed tomography in children with Abernethy malformation.

Background: Abernethy malformation is a rare congenital abnormality. Imaging examination is an important method for the diagnosis. The purpose of this study was to demonstrate manifestations of multi-slice computed tomography (MSCT) in Abernethy malformation and its diagnostic accuracy.

Multislice Computed Tomography Assessment of Tracheobronchial Patterns in Partial Anomalous Left Pulmonary Artery.

Objective: The aim of this study was to present relationship between partial anomalous left pulmonary artery (PALPA) and the tracheobronchial tree and patterns of the tracheobronchial tree assessed by multislice computed tomography (MSCT).

Methods: Nine patients were assessed by MSCT. The relationships between the tracheobronchial tree and PALPA and different tracheobronchial patterns, location of tracheobronchial stenosis, severity of stenosis, and associated cardiac defects were evaluated.

A prospective evaluation of contrast and radiation dose and image quality in cardiac CT in children with complex congenital heart disease using low-concentration iodinated contrast agent and low tube voltage and current.

Objective: To the assess image quality, contrast dose and radiation dose in cardiac CT in children with congenital heart disease (CHD) using low-concentration iodinated contrast agent and low tube voltage and current in comparison with standard dose protocol.

Methods: 110 patients with CHD were randomized to 1 of the 2 scan protocols: Group A (n = 45) with 120 mA tube current and contrast agent of 270 mgI/ml in concentration (Visipaque; GE Healthcare Ireland, Co., Cork, UK); and Group B (n = 65) with the conventional 160 mA and 370 mgI/ml concentration contrast (Iopamiro; Shanghai Bracco Sine Pharmaceutical Corp Ltd, Shanghai, China).

A prospective evaluation of the contrast, radiation dose and image quality of contrast-enhanced CT scans of paediatric abdomens using a low-concentration iodinated contrast agent and low tube voltage combined with 70% ASIR algorithm.

Purpose: To quantitatively and subjectively assess the image quality of and radiation dose for an abdominal enhanced computed tomography (CT) scan with a low tube voltage and a low concentration of iodinated contrast agent in children.

Methods: Forty-eight patients were randomised to one of the two following protocols: Group A (n=24, mean age 46.96±44.

Multi-slice computed tomography assessment of bronchial compression with absent pulmonary valve.

Background: Absent pulmonary valve is a rare cardiovascular anomaly that can result in profound tracheobronchial compression.

Objective: To demonstrate the advantage of multi-slice CT in diagnosing tracheobronchial compression, its severity as related to the adjacent dilated pulmonary arteries, and associated lung and cardiac lesions.

Materials And Methods: We included children with absent pulmonary valve who were reviewed by multi-slice CT during a 17-year period.
