Abstract
Radiomics is a discipline that involves studying medical images through their digital data. Using “artificial intelligence” algorithms, radiomics utilizes quantitative and high-throughput analysis of an image’s textural richness to obtain relevant information for clinicians, from diagnosis assistance to therapeutic guidance. Exploitation of these data could allow for a more detailed characterization of each phenotype, for each patient, making radiomics a new biomarker of interest, highly promising in the era of precision medicine. Moreover, radiomics is non-invasive, cost-effective, and easily reproducible in time. In the field of oncology, it performs an analysis of the entire tumor, which is impossible with a single biopsy but is essential for understanding the tumor’s heterogeneity and is known to be closely related to prognosis. However, current results are sometimes less accurate than expected and often require the addition of non-radiomics data to create a performing model. To highlight the strengths and weaknesses of this new technology, we take the example of hepatocellular carcinoma and show how radiomics could facilitate its diagnosis in difficult cases, predict certain histological features, and estimate treatment response, whether medical or surgical.

Abstract
Two patients with clinically mild congenital myopathies presented with chronic respiratory failure. Muscle weakness alone could not account for the respiratory insufficiency since static respiratory pressures were not markedly impaired, ventilation during exercise was normal, and daytime ventilation was normal if ventilatory assistance was provided at night. The ventilatory responses to inhaled carbon dioxide were very low, suggesting that impairment of the central nervous respiratory chemoreceptor contributed to hypoventilation. These patients and others described in the literature suggest that central depression of ventilation may occur more frequently than previously recognized in patients with muscular disorders. Patients with chronic respiratory failure due to central depression of respiratory drive can be effectively managed by assisted ventilation at night.
