A data‐driven algorithm to determine 1H‐MRS basis set composition

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Metabolite amplitude estimates derived from linear combination modeling of MR spectra depend on the precise list of constituent metabolite basis functions used (the “basis set”). The absence of clear consensus on the “ideal” composition or objective criteria to determine the suitability of a particular basis set contributes to the poor

Accelerated water residual removal in MRS: Exploring deep learning versus fitting‐based approaches

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Removing water residual signals from MRS spectra is crucial for accurate metabolite quantification. However, currently available algorithms are computationally intensive and time‐consuming, limiting their clinical applicability. This work aims to propose and validate two novel pipelines for fast water residual removal in MRS.

Real time intravascular ultrasound evaluation and stent selection for cerebral venous sinus stenosis associated with idiopathic intracranial hypertension

Scientific Reports
The value of intravascular ultrasound (IVUS) in the diagnosis and treatment of the venous system is not well established. Introducing a novel approach to utilizing IVUS to evaluate cerebral venous sinus (CVS) stenosis and select stent.

Diagnostic neuroradiology for the interventional neuroradiologist

World Journal of Radiology, 2013
In order to further improve the impact of the continuously evolving neurointerventional techniques, the interventional neuroradiologist needs to have at his disposal more powerful techniques to image the central nervous system. With the recent development of diagnostics techniques that are computed tomography and magnetic resonance based we are now ...

Motion‐robust T2∗$$ {\mathrm{T}}_2^{\ast } $$ quantification from low‐resolution gradient echo brain MRI with physics‐informed deep learning

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose T2∗$$ {\mathrm{T}}_2^{\ast } $$ quantification from gradient echo magnetic resonance imaging is particularly affected by subject motion due to its high sensitivity to magnetic field inhomogeneities, which are influenced by motion and might cause signal loss. Thus, motion correction is crucial to obtain high‐quality T2∗$$ {\mathrm{T}}_2^

Embolization of iatrogenic renal arteriovenous fistula – a case report

Journal of Ultrasonography, 2018
Renal artery pseudoaneurysms and arteriovenous fistulae most often occur as an iatrogenic complication. The article discusses a case of a patient diagnosed with an arteriovenous fistula and a pseudoaneurysm.
