AI Article Synopsis
- This study aimed to compare the accuracy of measuring the thoracic aorta in patients with aortic disease using two MRI techniques (ECG-MRA and P-MRA) against a CT scan (CTA).
- A total of 31 patients were assessed, with measurements taken by two independent readers across seven aortic segments, showing strong agreement overall, but weaker at the aortic annulus.
- While the MRI techniques provided similar accurate measurements to CTA, the image quality was generally lower for MRA, especially at the aortic root.
Article Abstract
Objective: The aim of this study was to evaluate agreement of measured thoracic aortic caliber in patients with aortic disease, using electrocardiographically-(ECG) and pulse-gated breath-hold noncontrast balanced steady-state free precession MRA (ECG-MRA, P-MRA) at 1.5 T, compared with ECG-gated computed tomographic angiography (CTA).
Methods: Thirty-one patients underwent ECG-MRA, P-MRA, and CTA. Two readers independently measured aortic caliber in 7 segments, with agreement between techniques and readers evaluated. Image quality was qualitatively assessed.
Results: There was overall excellent agreement among ECG-MRA, P-MRA, and CTA for measured aortic caliber (Lin's concordance correlation coefficient ≥0.94, all comparisons); however, lower concordance was noted at the annulus (Lin's concordance correlation coefficient <0.6) at segmental assessment. There was excellent interreader agreement for aortic caliber for all 3 techniques (intraclass correlation coefficient >0.94). Image quality was poorer for both MRA techniques compared with CTA, particularly at the aortic root.
Conclusions: Electrocardiographically-gated MRA and P-MRA at 1.5 T achieve comparable thoracic aortic measurements to gated CTA in clinical patients, despite inferior image quality.

Introduction: The global increase in cardiovascular diseases has resulted in an augmented development of artificial small-caliber vascular grafts used in bypass graft surgeries, such as coronary and distal artery bypass graft surgeries. However, no consensus exists regarding the best method for creating vascular grafts. Poly-ε-caprolactone (PCL) is a biocompatible and biodegradable material that has been widely studied as a scaffold for tissue regeneration, inclusive of vascular grafts.

Background: The purpose of this study was to compare CCTA images generated using HIR and IMR algorithm with the reference standard ICA, and to determine to what extend further improvements of IMR over HIR can be expected.
Methods: This retrospective study included 60 patients with low to intermediate CAD risk, who underwent coronary CTA (with HIR and IMR) and ICA. ICA was used as reference standard.

Currently, there is often a lack of suitable small-caliber graft vessels for treating cardiovascular diseases because of thrombosis and intimal hyperplasia. Tissue engineered vascular grafts (TEVGs) promise a potential solution to this issue. Acellular vascular matrix with good mechanical properties and biocompatibility is commonly used as a tissue engineered scaffold.

Objective: Percutaneous closure devices for arterial sheaths of sufficient caliber to deliver aortic endografts have a published success rate of 90% to 95%. Despite this, they are frequently avoided in patients with genetic aortopathy due to concern for high failure rates and increased complications in the setting of compromised tissue integrity. This study aims to compare rates of access site complications after large bore percutaneous access among patients with and without confirmed genetic aortopathy.

Background: Vascular transplantation is an effective treatment for severe vascular lesions. The design of the bioactive and mechanical properties of small-caliber vascular grafts is critical for their application in tissue engineering. In this study, we sought to develope a small-caliber vascular graft by electrospinning a mixture of a human acellular amniotic membrane (HAAM) and polycaprolactone (PCL).
