The authors analyze the results of 50 computed angiographies made for osteosarcoma and Ewing's sarcoma. Better tolerated than conventional angiography computed angiography is also more sensitive in preoperative evaluation of effectiveness of neoadjuvant chemotherapy. Automatic subtraction, direct measuring of tumor size and vascularization density give to angiographic changes after chemotherapy the most predictive value. After conservative surgery or radiotherapy digital angiography provides most reliable local follow up.

Diagnostic accuracy of deep learning algorithm for detecting unruptured intracranial aneurysms in magnetic resonance angiography: a multicenter pivotal trial.

Introduction: Intracranial aneurysm rupture is associated with high mortality and disability rates. Early detection is crucial, but increasing diagnostic workloads place significant strain on radiologists. We evaluated the efficacy of a deep learning algorithm in detecting unruptured intracranial aneurysms (UIAs) using time-of-flight (TOF) magnetic resonance angiography (MRA).

Objective: Moyamoya angiopathy (MMA) is characterized by the plasticity to develop endogenous collateral blood vessels to compensate for progressive steno-occlusion of proximal intracranial arteries. Bypass surgery has been anecdotally reported to induce regression of these collateral vessels, but a detailed analysis of their natural history is lacking. Here, the authors characterize these collaterals after bypass surgery.

Objective: Brucellosis-induced aortic aneurysm (BIA), as a rare yet highly life-threatening type of infectious aortic aneurysm, currently lacks standardized treatment protocols. The primary objective of this study is to thoroughly evaluate the safety and efficacy of endovascular therapy using a combination of covered stents and drug irrigation techniques for the treatment of BIA. This endeavor aims to provide a scientific basis for the clinical management of this disease.

Commun Med (Lond)
March 2025
Department of Experimental Physics 5 (Biophysics), Julius-Maximilians University, Würzburg, Germany.
Background: Magnetic particle imaging (MPI) allows for radiation-free visualization of tracers without background signal. With the first human-sized interventional MPI scanner being recently developed, the aim of the present study was to test its performance for guiding of endovascular procedures in a realistic perfusion model.
Methods: Three fresh-frozen cadaveric legs were prepared to establish continuous circulation in the superficial femoral artery via introducer sheaths in the inguinal and infragenicular region.
MR-VWI concentric ring sign: a potential imaging feature of internal carotid artery pseudo occlusion and predictive value for successful recanalization.

Background: Predicting the success of endovascular recanalization in non-acute internal carotid artery occlusion (NICAO) remains a challenge.
Objective: To examine the hypothesis that the concentric ring sign observed on high-resolution magnetic resonance vessel wall imaging (MR-VWI) could serve as a potential imaging biomarker to improve the accuracy of predicting recanalization success and guide treatment decisions.
Methods: A retrospective analysis was conducted on patients with NICAO who underwent endovascular treatment at our institution between January 2020 and December 2023.
