CT coronary fractional flow reserve based on artificial intelligence using different software: a repeatability study.

Objective: This study aims to assess the  consistency of various CT-FFR software, to determine the reliability of current CT-FFR software, and to measure relevant influence factors. The goal is to build a solid foundation of enhanced workflow and technical principles that will ultimately improve the accuracy of measurements of coronary blood flow reserve fractions. This improvement is critical for assessing the level of ischemia in patients with coronary heart disease.

Therapy response assessment of non-small cell lung cancer using dual-energy computed tomography iodine map.

Objective: To investigate feasibility of the quantitative parameters of dual-energy computed tomography (DECT) to assess therapy response in advanced non-small cell lung cancer (NSCLC) compared with the traditional enhanced CT parameters based on the Response Evaluation Criteria in Solid Tumors (RECIST) guidelines.

Methods: Forty-five patients with unresectable locally advanced NSCLC who underwent DECT before and after chemotherapy or concurrent chemoradiotherapy (cCRT) were prospectively enrolled. By comparing baseline studies with follow-up, patients were divided into two groups according to RECIST guidelines as follows: disease control (DC, including partial response and stable disease) and progressive disease (PD).

Molecular Traits and Functional Analysis of the CLAVATA3/Endosperm Surrounding Region-Related Small Signaling Peptides in Three Species of Genus.

The CLAVATA3/endosperm surrounding region-related (CLE) small peptides are a group of C-terminally encoded and post-translationally modified signal molecules involved in regulating the growth and development of various plants. However, the function and evolution of these peptides have so far remained elusive in cotton. In this study, 55, 56, and 86 genes were identified in the , and genomes, respectively, and all members were divided into seven groups.

Right atrial appendage aneurysm complicated with atrial septal defect: A rare case report.

Right atrial appendage aneurysms (RAAAs) are rare heart malformations, presenting as isolated anomalies or co-existing with other structural heart diseases. We describe a rare case of RAAA complicated with an atrial septal defect (ASD). The diagnosis was established using transthoracic echocardiography and confirmed using cardiac magnetic resonance imaging.

Assessment of Acute Pulmonary Embolism by Computer-Aided Technique: A Reliability Study.

BACKGROUND Acute pulmonary embolism is one of the most common cardiovascular diseases. Computer-aided technique is widely used in chest imaging, especially for assessing pulmonary embolism. The reliability and quantitative analyses of computer-aided technique are necessary.

Right coronary artery-right ventricular fistula complicated with infective endocarditis.

Coronary artery fistula (CAF) is a congenital disease in which a communication forms between one or more coronary arteries and a cardiac chamber or great vessel. We describe an infrequent case of right coronary artery (RCA) fistula into the right ventricle (RV) complicated by infective endocarditis in a child. The patient received echocardiography and contrast-enhanced multidetector computed tomography (MDCT).
