Differential Expression of LncRNA MIAT and Its Clinical Significance in Intracranial Aneurysms
Increased expression of LncRNA MIAT is associated with an elevated risk of intracranial aneurysm rupture. ABSTRACT Purpose: Intracranial aneurysm (IA) is characterized by localized dilation or ballooning of a blood vessel in the brain with life‐threatening consequences.

ABSTRACT Vascular complications (VCs) associated with Transcatheter Aortic Valve Replacement (TAVR), particularly iliac artery rupture, pose significant challenges. We report a case of complete iliac artery disruption during TAVR. A combination of a covered stent and artificial blood vessel repair was employed to achieve revascularization of the iliac ...

Mixed one-bit compressive sensing with applications to overexposure correction for CT reconstruction [PDF]
When a measurement falls outside the quantization or measurable range, it becomes saturated and cannot be used in classical reconstruction methods. For example, in C-arm angiography systems, which provide projection radiography, fluoroscopy, digital subtraction angiography, and are widely used for medical diagnoses and interventions, the limited ...

Abstract Purpose To achieve ultra‐high temporal resolution non‐contrast 4D angiography with improved spatiotemporal fidelity. Methods Continuous data acquisition using 3D golden‐angle sampling following an arterial spin labeling preparation allows for flexibly reconstructing 4D dynamic angiograms at arbitrary temporal resolutions. However, k‐space data
