Abstract: Focal cortical dysplasias are a common cause of refractory epilepsy. The findings on magnetic resonance imaging can be subtle, requiring optimal quality examination as well as extensive experience and dedica-tion from the neuroradiologist. Even under the best conditions, there are a considerable number of cases in which an injury cannot be identified. The sensitivity of its detection varies between 20 and 70%. The Morphometric Analysis Program (MAP), is a post-processing program of the magnetic resonance image whose objective is to increase the sensitivity in the detection of focal cortical dysplasia (CFD). This program works by comparing the shape, thickness and distribution of gray matter and white matter of a patient with a database of normal brains. As a result, MAP delivers 3 images that correspond to statistical volumetric maps called the union, extension and thickness map. This article discloses the operation of MAP in its different stages as well as its practical application, through some cases.","PeriodicalId":35339,"journal":{"name":"Revista Chilena de Radiologia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46836418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

COVID-19 is a viral disease produced by SARS-CoV-2 that was declared a global pandemic by the World Health Organization (WHO) on March 2020. The pandemic has caused a great impact in several medical disciplines, including radiology. Radiologists have a fundamental role in identifying characteristic imaging findings of the COVID-19 disease. The studies regarding extra pulmonary findings of COVID-19 are relatively new. These findings include cardiac, thoracic and abdominal manifestations as a result of the pro-thrombotic state produced by the virus. Unexpected extrapulmonary imaging findings of COVID-19 patients from two different institutions are presented. In addition, we conducted a literature review of extra pulmonary manifestations and complications of this disease. The aim of this study is to provide information for an early recognition and optimal management of these complications.","PeriodicalId":35339,"journal":{"name":"Revista Chilena de Radiologia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46501442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its main indication has been the study of acute cerebral infarction in order to determine ischemic penumbra susceptible to reperfusion therapy. However, there is evidence of its usefulness in other situations such as: hypo - hyperperfusion states, tumor grading in glial neoplasms, head trauma and others. The advanta-ges of CTP are its availability, speed and the possibility of performing it in conjunction with angiographic studies. However, it has disadvantages derived from the use of ionizing radiation and iodinated contrast agent.
