“…Endovascular stent implantation has become a common method for the treatment of vascular diseases, but restenosis after stent implantation is becoming increasingly serious. 14 Therefore, precise imaging of the stented vessels and early identification of ISR is important in follow-up. With remarkable technological advances in recent years, DS-CTA has become an indispensable method for noninvasive evaluation of the coronary artery lumen in patients with ischemic heart diseases.…”

“…However, due to its rapid acquisition speed, high spatial and temporal resolution, and powerful image post-processing abilities, DS-CTA has been proven tremendously useful for examining the cardiovascular system with stent artifacts. 14 To the best of our knowledge, the new technique applied to the lower limb artery ISR has not been fully addressed, but cross-sectional viewing of diseased arterial segments was frequently required for visual assessment of the artery stent. Therefore, our aim was to explore the value of the DS-CTA for diagnosis of ISR after lower limb artery stenting.…”

Objectives This paper is aimed to explore the value of double source CT angiography (DS-CTA) for diagnosing in-stent restenosis in lower limb artery. Methods From January 2016 to October 2018, all patients with stent in lower limb artery in our hospital were investigated by both DS-CTA and digital subtraction angiography. We measured the minimum lumen diameter and the diameter of the proximal normal vessels under each stent placement. The in-stent restenosis is defined as restenosis when the lumen area decreased by more than 50%. Digital subtraction angiography was performed within 1 week after DS-CT scan. Relationship between DS-CTA and digital subtraction angiography for diagnosing in-stent restenosis in lower limb artery was analyzed. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of DS-CTA for diagnosis of in-stent restenosis were analyzed with digital subtraction angiography as the reference standard. A total of 68 stents were placed in 51 patients. Among these patients, 27 cases were diagnosed as in-stent restenosis, presenting as endovascular contrast agent bias or crescent filling defect with the lumen area reducing over 50%, 6 cases of which had no significant in-stent restenosis by digital subtraction angiography analysis. Furthermore, 12 cases were occlusion, in which there was no high density contrast agent in stents; the remaining 41 stents were unobstructed and the contrast agent was filled well, 8 cases of which had significant in-stent restenosis by digital subtraction angiography analysis. In addition, four stents were deformed or distorted. Statistical analysis demonstrated the concentrations of DS-CTA and digital subtraction angiography in diagnosing in-stent restenosis for lower limb artery were closely related, and the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of DS-CTA were 72.4%, 84.6%, 77.8%, 80.5%, and 79.4%, respectively. Conclusion DS-CTA has a potential reliability for diagnosis of in-stent restenosis in lower limb artery, which may be further improved to be used for clinical interventional treatment of vascular diseases.

“…Dual-source computed tomography angiography (DSCTA) equipment uses two X-ray tubes and detectors, which provide for advancement in temporal and spatial resolutions [ 74 , 75 ], thereby facilitating an additional reduction in artifact generation leading to significantly increased quality of cardiac imaging independent of heart rate [ 76 ].…”

“…Per-segment analysis of coronary artery disease (CAD) attains high SEN (94%) and SPE (97%) when the DSCTA method is employed [ 77 ]. Though this technique provides high resolution, both spatial and temporal, along with a marked reduction of the effects of motion and blooming artifacts [ 78 , 79 ], thicker strut slices and higher density stent metal have been more challenging to diagnose [ 74 ].…”

In-stent restenosis concerning the coronary artery refers to the blood clotting-caused re-narrowing of the blocked section of the artery, which is opened using a stent. The failure rate for stents is in the range of 10% to 15%, where they do not remain open, thereby leading to about 40% of the patients with stent implantations requiring repeat procedure within one year, despite increased risk factors and the administration of expensive medicines. Hence, today stent restenosis is a significant cause of deaths globally. Monitoring and treatment matter a lot when it comes to early diagnosis and treatment. A review of the present stent monitoring technology as well as the practical treatment for addressing stent restenosis was conducted. The problems and challenges associated with current stent monitoring technology were illustrated, along with its typical applications. Brief suggestions were given and the progress of stent implants was discussed. It was revealed that prime requisites are needed to achieve good quality implanted stent devices in terms of their size, reliability, etc. This review would positively prompt researchers to augment their efforts towards the expansion of healthcare systems. Lastly, the challenges and concerns associated with nurturing a healthcare system were deliberated with meaningful evaluations.

Extraction Method of Coronary Artery Blood Vessel Centerline in CT Coronary Angiography

et al. 2019

Aiming at the problem that the traditional coronary artery centerline extraction method is computationally intensive and requires a large number of manual interventions, a fully automatic coronary artery centerline tracking extraction method is proposed. First, adaptive adaptation of coronary vessels was performed based on different Fresenius norms designed for coronary scale. A multi-scale differential operator is constructed based on the vascular gray-scale distribution to establish a discriminant function, thereby obtaining the initial position and tracking direction of the seed point. Then, the new ridge point and tracking direction are optimally detected within the local arc length of the initial direction to ensure that the correct ridge position can still be obtained with large error interference. Finally, the pseudo vascular centerline is removed using the vascular topology feature detection method. The experimental results show that the method can accurately extract the blood vessel center line, direction vector and other information in the coronary angiography image without manual intervention, and can be used in the computer-assisted diagnosis and treatment process of clinical cardiovascular disease.
