A Case of Treatment With a Combination of Covered Stents and Artificial Blood Vessel for Iliac Artery Rupture During Transcatheter Aortic Valve Replacement

Clinical Case Reports, Volume 13, Issue 5, May 2025.
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]

arXiv, 2017
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 ...

Technique selection and technical developments for 2D dual‐energy subtraction angiography on an interventional C‐arm

Medical Physics, Volume 52, Issue 5, Page 3228-3242, May 2025.
Abstract Background Dual‐energy (DE) x‐ray image acquisition has the potential to provide material‐specific angiographic images in the interventional suite. This approach can be implemented with novel detector technologies, such as dual‐layer and photon‐counting detectors.

Ultra‐high temporal resolution 4D angiography using arterial spin labeling with subspace reconstruction

Magnetic Resonance in Medicine, Volume 93, Issue 5, Page 1924-1941, May 2025.
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
