Classification of Hematoma: Joint Learning of Semantic Segmentation and Classification [PDF]

open access: yesarXiv, 2021
Cerebral hematoma grows rapidly in 6-24 hours and misprediction of the growth can be fatal if it is not operated by a brain surgeon. There are two types of cerebral hematomas: one that grows rapidly and the other that does not grow rapidly. We are developing the technique of artificial intelligence to determine whether the CT image includes the ...

Diagnóstico etiológico del infarto cerebral en el hospital comarcal

open access: yesRevista de Neurología, 2003
INTRODUCTION: Cerebral infarction (CI) can be classified aetiologically in several different ways using explicit diagnostic criteria. However, the extent to which these diagnostic criteria are actually implemented in clinical practice is unknown. Aims.

Segmentation of TCD Cerebral Blood Flow Velocity Recordings [PDF]

open access: yesarXiv, 2018
A binary beat-by-beat classification algorithm for cerebral blood flow velocity (CBFV) recordings based on amplitude, spectral and morphological features is presented. The classification difference between 15 manually and algorithmically annotated CBFV records is around 5%.

Adversarial cycle-consistent synthesis of cerebral microbleeds for data augmentation [PDF]

open access: yesarXiv, 2021
We propose a novel framework for controllable pathological image synthesis for data augmentation. Inspired by CycleGAN, we perform cycle-consistent image-to-image translation between two domains: healthy and pathological. Guided by a semantic mask, an adversarially trained generator synthesizes pathology on a healthy image in the specified location. We

Flow 2.0 -a flexible, scalable, cross-platform post-processing software for realtime phase contrast sequences [PDF]

open access: yesarXiv, 2022
Flow 2.0 is an end-to-end easy-of-use software that allows us to quickly, robustly and accurately perform a batch process real-time phase contrast data and multivariate analysis of the effect of respiration on cerebral fluids circulation. Synopsis (99/100) Real-time phase contrast sequences (RT-PC) have potential value as a scientific and clinical tool

Diagnosis of CADASIL disease in normotensive and non-diabetics with lacunar infarct

open access: yesNeurología (English Edition), 2011
Background: CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) is characterized by recurrent cerebral ischemic episodes of the lacunar subtype usually without traditional vascular risk factors.

Increased blood pressure variability upon standing up improves reproducibility of cerebral autoregulation indices [PDF]

open access: yesarXiv, 2017
Dynamic cerebral autoregulation, that is the transient response of cerebral blood flow to changes in arterial blood pressure, is currently assessed using a variety of different time series methods and data collection protocols. In the continuing absence of a gold standard for the study of cerebral autoregulation it is unclear to what extent does the ...
