“…Future research will require higher-quality clinical case data and optimized experimental designs to further validate and supplement the existing conclusions. In-depth exploration of compressed sense technique parameters and other important diagnostic indicators is needed to provide stronger support for the diagnosis of vascular diseases in clinical practice [22].…”

In recent years, Compressed Sense technology has emerged as a promising image reconstruction method, demonstrating great potential in reducing data acquisition time and improving image quality. This study aims to explore the application of compressed sense technology in cerebral magnetic resonance angiography (MRA), compare it with conventional vascular imaging techniques, and evaluate its advantages in clinical practice. The study utilized a Philips Ingenia 3.0T magnetic resonance imaging (MRI) system and included a certain number of normal subjects and patients with cerebral vascular lesions. Both conventional vascular imaging techniques and compressed sense technology were employed for scanning, and the differences between the two methods in terms of image quality, acquisition time, and other aspects were compared. Image quality assessment indicators included overall image quality, blood vessel display clarity, and blood vessel contrast, among others. Additionally, the application of both techniques in specific clinical cases was analyzed. The results showed that, compared to conventional vascular imaging techniques, compressed sense technology significantly shortened the scanning time while ensuring image quality. In the detection of certain diseases such as cerebral aneurysms and ischemic cerebrovascular lesions, compressed sense technology not only effectively improved the clarity and contrast of blood vessel display but also made the detection process more convenient and accurate. Moreover, for patients with severe movement disorders or those who cannot tolerate long scanning times, compressed sense technology is a more suitable choice. In conclusion, compressed sense technology exhibits significant advantages in cerebral MRA. It demonstrates clear advantages over conventional vascular imaging techniques in terms of image quality, acquisition time, and other aspects, and it has high application value in the detection of specific diseases. We recommend the extensive application of compressed sense technology in clinical practice and further exploration of its application in other areas of MRI imaging.

“…The occurrence, development, and pathological changes of these vascular diseases are closely related to the geometrical morphology and microstructure of blood vessels. The aforementioned diseases also interact with the mechanical properties and hemodynamic characteristics of the vascular wall (Tang and Li, 2016;Tang and Li, 2018;Yanxia et al 2017). Therefore, systematically studying the geometrical morphology and mechanical properties of DTA is necessary for the clinical diagnosis and treatment of aortic disease.…”

2018)Circumferential variation in mechanical characteristics of porcine descendingAbstract: Arterial characterization of healthy descending thoracic aorta (DTA) is indispensable in determining stress distributions across wall thickness and different regions that may be responsible for aorta inhomogeneous dilation, rupture, and dissection when aneurysm occurs. Few studies have shown the inhomogeneity of DTA along the aorta tree considering changes in circumferential direction. The present study aims to clarify the circumferential regional characterization of DTA. Porcine DTA tissues were tested according to region and orientation using uniaxial tension.For axial test, results show that the difference in circumferential direction was mainly in collagen fiber modulus, where the anterior collagen fiber modulus was significantly lower than the posterior quadrant. For circumferential test, the difference in circumferential direction was mainly in the recruitment parameter, where the circumferential stiffness is significantly higher in the posterior region at physiological maximum stress. The proximal posterior quadrant and left quadrant showed significantly lower axial collagen fiber stiffness than the right and anterior quadrants, which may be a factor in aneurysm development. Furthermore, the constitutive parameters for similar detailed regions can be used by biomedical engineers to investigate improved therapies and thoroughly understand the initial stage of aneurysm development. The regional collagen fiber modulus can help improve our understanding of the mechanisms of arterial dilation and aortic dissection.
