Introduction: Contrast computed tomography and magnetic resonance imaging are widely used due to its image quality and ability to study pancreatic and peripancreatic morphology. The understanding of the various subtypes of the disease and identification of possible complications requires a familiarity with the terminology, which allows effective communication between the different members of the multidisciplinary team. Aim: Demonstrate the terminology and parameters to identify the different classifications and findings of the disease based on the international consensus for acute pancreatitis ( Atlanta Classification 2012). Methods: Search and analysis of articles in the "CAPES Portal de Periódicos with headings "acute pancreatitis" and "Atlanta Review". Results: Were selected 23 articles containing radiological descriptions, management or statistical data related to pathology. Additional statistical data were obtained from Datasus and Population Census 2010. The radiological diagnostic criterion adopted was the Radiology American College system. The "acute pancreatitis - 2012 Rating: Review Atlanta classification and definitions for international consensus" tries to eliminate inconsistency and divergence from the determination of uniformity to the radiological findings, especially the terminology related to fluid collections. More broadly as "pancreatic abscess" and "phlegmon" went into disuse and the evolution of the collection of patient fluids can be described as "acute peripancreatic collections", "acute necrotic collections", "pseudocyst" and "necrosis pancreatic walled or isolated". Conclusion: Computed tomography and magnetic resonance represent the best techniques with sequential images available for diagnosis. Standardization of the terminology is critical and should improve the management of patients with multiple professionals care, risk stratification and adequate treatment.

Introduction: Among the screening tests for colorectal cancer, colonoscopy is currently considered the most sensitive and specific technique. However, computed tomography colonography (CTC), magnetic resonance imaging (MRI), and transrectal ultrasonography have gained significant ground in the clinical practice of pre-treatment, screening and, more recently, post-treatment and surgical evaluation. Objective: To demonstrate the high accuracy of CT and MRI for pre and postoperative colorectal cancer staging. Methods: Search and analysis of articles in Pubmed, Scielo, Capes Periodicals and American College of Radiology with headings “colorectal cancer” and “colonography”. Weew selected 30 articles that contained radiological descriptions, management or statistical data related to this type of neoplasia. The criteria for radiological diagnosis were the American College of Radiology. Results : The great majority of patients with this subgroup of neoplasia is submitted to surgical procedures with the objective of cure or relief, except those with clinical contraindication. CTC colonography is not the most commonly used technique for screening; however, it is widely used for treatment planning, assessment of the abdomen for local complications or presence of metastasis, and post-surgical evaluation. MRI colonography is an alternative diagnostic method to CT, recommended by the American Society of Gastrointestinal Endoscopy. Although there are still no major studies on the use of MRI for screening, the high resolution examination has now shown good results for the American Joint Committee on Cancer TNM classification. Conclusion: MRI and CT represent the best means for colorectal neoplasm staging. The use of these methods as screening tools becomes beneficial to decrease complications and discomfort related to colonoscopy.

InTRODUÇÃODisfagia é o principal sintoma das doenças do esôfago sendo a sua caracterização muito importante para o manejo destes pacientes 5 . Ela é representada pela dificuldade em deglutir o alimento ingerido no trajeto da orofaringe até o estômago, podendo estar associada a outros sintomas como: regurgitação, aspiração traqueobrônquica, dor retroesternal independente do esforço físico (relacionada ou não à alimentação), pirose, rouquidão, soluço e odinofagia. Esta entidade é queixa comum na prática clínica diária envolvendo várias especialidades na sua investigação 12,13 . MÉTODOFoi realizada revisão atualizada da literatura internacional através do Pubmed (www.pubmed.com) e nacional (www.lilacs.br) utilizando-se a seguinte palavra-chave: transtornos da deglutição, obtendo-se grande quantidade de artigos dos quais 18 foram aproveitados nesta revisão por conterem abordagem ampla e detalhada do tema.

RESUMO -Introdução -A disfagia é o principal sintoma das doenças do esôfago e é representada pela dificuldade em deglutir o alimento ingerido no trajeto da orofaringe até o estômago. Ela é queixa comum na prática clínica diária envolvendo várias especialidades na sua investigação. Métodos -Foi realizada revisão atualizada da literatura internacional através do Pubmed (www.pubmed.com) e nacional (www.lilacs.br) utilizando-se as seguintes palavras-chave: disfagia e transtornos da deglutição. A extensão do tema foi limitado aos seguintes enfoques: etiologia, diagnóstico e exames complementares mais aplicáveis à exploração propedêutica. Conclusão -Embora a literatura apresente bom entendimento do processo disfágico, no diagnóstico preciso de sua causa há freqüentemente necessidade de múltiplos exames complementares que associados fazem melhor entender o que acomete o paciente e orientará mais adequadamente a conduta a ser tomada DESCRITORES -Transtornos da deglutição. Esofagopatias. REVISÃO DA LITERATURA EtiologiaAs causas de disfagia dividem-se em dois grandes grupos: 1) as originadas de anormalidades do funcionamento da musculatura do esôfago, que é chamada de disfagia neuromuscular, e 2) as de causa mecânica com comprometimento da luz do órgão por lesões da sua própria parede ou por compressão extrínseca.Outra causa de disfagia, mas que não está relacionada às doenças do esôfago é a disfagia orofaríngea, que é sintoma inespecífico causado por grupo de enfermidades estruturais da orofaringe. O paciente manifesta dificuldade no trânsito dos alimentos desde a boca até o esôfago, ou seja, no início da fase involuntária da deglutição 16 . Esta entidade clínica tem grande importância quando associada às doenças cerebrovasculares devido ao risco de pneumonia aspirativa 6 . Pacientes submetidos à laringectomia que apresentam disfagia no pós-operatório, têm como principal causa pseudodivertículos criados em conseqüência da técnica cirúrgica empregada 14 .

For colloid goiter there is a positive and significant association between the two variables - marker index and optical density -, while for the papillary carcinoma, this is not proved. The quantitative analysis for caspase-3 demonstrates that apoptosis is larger in the papillary carcinoma of the thyroid than in colloid goiter.

Objectives To evaluate the diagnostic accuracy of chest CT for the diagnosis of COVID-19 associated with the clinical presentation and in relation to the PCR-RT. Sensitivity, specificity, positive predictive value and negative predictive value, gender, age group and degree of lung involvement will be evaluated. Methods We evaluated 1545 patients with chest CT, delineating the age range and degree of lung involvement, and 306 patients with chest CT and PCR-RT. Results Of the 1545 examinations, 53% were men and 47% were women, there was greater involvement in the 50-59 age group. In the pulmonary study, 55.05% were COVID-19. In the degree of lung involvement 37.70% were mild, 35.76% were moderate, and 26.54% were severe. In the distribution by age, there was a greater involvement between 50-59 years with 56% between moderate (27.6%) and severe (28.0%). Between tomography and PCR-RT, the sensitivity was 68.8%, specificity 59.5%, accuracy 91.3%, with prevalence 31.9%, positive predictive value 44.3% and negative predictive value 80.3%, in females, sensitivity 55.3%, positive predictive value 37.1%, negative predictive value 75.3%, in males, sensitivity 81.6%, positive predictive value 50, 6 and negative predictive value 86.6%.The sensitivities are different between the genders with p of 0.005 and specificity of 0.938, with age effect, starting at 45 years we have a p of 0.057 that decreases to 0.006 at 80 years for sensitivity and specificity. Conclusions The sensitivity and accuracy of CT scan in relation to PCR-RT was significant. Sensitivity increases with prevalence and in the older age group and in men.
