A survey on deep learning applied to medical images: from simple artificial neural networks to generative models.

Deep learning techniques, in particular generative models, have taken on great importance in medical image analysis. This paper surveys fundamental deep learning concepts related to medical image generation. It provides concise overviews of studies which use some of the latest state-of-the-art models from last years applied to medical images of different injured body areas or organs that have a disease associated with (e.

LDA filter: A Latent Dirichlet Allocation preprocess method for Weka.

This work presents an alternative method to represent documents based on LDA (Latent Dirichlet Allocation) and how it affects to classification algorithms, in comparison to common text representation. LDA assumes that each document deals with a set of predefined topics, which are distributions over an entire vocabulary. Our main objective is to use the probability of a document belonging to each topic to implement a new text representation model.

Herniation of the left atrial appendage through a congenital partial pericardial defect.

We present a case of herniation of the left atrial appendage through a congenital partial absence of the pericardium. The diagnosis was demonstrated by echocardiography and the surgical correction achieved with autologous pericardium.

Embolization of the systemic arteries of the lung.

Embolization of the systemic arteries of the lung (described by Remy and colleagues in 1973) is now a useful method for the treatment of hemoptysis or hemorrhagic lesions of the lung prior to surgical treatment, or for local treatment of hemoptysis when surgery is contraindicated or unnecessary. The technique is based on the anatomy of the different divisions of the systemic circulation (bronchial and extrabronchial), which for various physiologic reasons may develop hypervascularization. The results, complications, and contraindications of systemic embolization have previously been described and the technique is now commonly practiced.

[Contribution of digital venous angiography to the evaluation of arterial hypertension. Cost evaluation].

Concerning 100 intravenous digital subtraction angiographies (IV DSA) performed for the study of arterial hypertension, the results are discussed according to two different achievements: diagnostic and economic. One hundred patients have been examined after the intravenous (IV) injection of contrast material, seventy times in peripheral and thirty times in central venous system. Out of 94 examinations that could be interpreted, 10 revealed stenosis of renal arteries higher than 50 per cent, one revealed fibromuscular dysplasia.
