Article Abstract
Recently vascular neurosurgery is on stage of comparing of different techniques for intracranial aneurisms treatment. Clinical and randomized studies provide with data that different drugs and techniques have neuroprotective effect, for example haemogenesis growth factors. To introduce any growth factors in practice the research proving the effectiveness of the drug must be carried out. Accurate and complete characteristics of treatment outcomes play the main role in all studies. Terms of outcomes assessment must be characterized and patients must be distributed in order of their condition. The article briefly reviews the problem of comparative assessment of different techniques for intracranial aneurisms treatment.

Article Synopsis
- * Despite initial treatment, he later experienced psychosis and tremors, with subsequent MRI revealing new lesions and positive anti-NMDAR antibodies, indicating an autoimmune response.
- * Prompt recognition and treatment of post-surgical inflammatory processes are crucial, as herpetic encephalitis can potentially trigger anti-NMDAR encephalitis, requiring immediate medical intervention.

This study aimed to employ a two-stage deep learning method to accurately detect small aneurysms (4-10 mm in size) in computed tomography angiography images.This study included 956 patients from 6 hospitals and a public dataset obtained with 6 CT scanners from different manufacturers. The proposed method consists of two components: a lightweight and fast head region selection (HRS) algorithm and an adaptive 3D nnU-Net network, which is used as the main architecture for segmenting aneurysms.

Background: Three-dimensional time-of-flight magnetic resonance angiography (TOF-MRA) is a largely adopted non-invasive technique for assessing cerebrovascular diseases. We aimed to optimize the 7-T TOF-MRA acquisition protocol, confirm that it outperforms conventional 3-T TOF-MRA, and compare 7-T TOF-MRA with digital subtraction angiography (DSA) in patients with different vascular pathologies.
Methods: Seven-tesla TOF-MRA sequences with different spatial resolutions acquired in four healthy subjects were compared with 3-T TOF-MRA for signal-to-noise and contrast-to-noise ratios as well as using a qualitative scale for vessel visibility and the quantitative Canny algorithm.

Q fever is an ubiquitous zoonosis caused by Coxiella burnetii, an intracellular bacterium that can produce acute or chronic infections in humans. These forms are characterized by different evolution, serological profile and treatment that must be very long to achieve a cure in chronic forms. However, the serological profile for diagnosis and the real value of serology for predicting outcome are controversial, and management dilemmas for many patients with Q fever infection are continuously emerging.
