Revista Brasileira de Ginecologia e Obstetrícia , 2001,
Abstract: Objetivo: verificar a acurácia do ultra-som transabdominal (USTA) em determinar as altera es fisiológicas e patológicas do volume uterino e comparar o volume do útero ao USTA e ultra-som transvaginal (USTV), procurando verificar a rela o dos métodos. Métodos: inicialmente foram revistos, retrospectivamente, 1186 exames ecográficos pélvicos (USTA e USTV), verificando-se as principais doen as e indica es para estes exames. A seguir, foram selecionados 480 USTA sem doen as uterinas e correlacionou-se o volume uterino com a idade e paridade. Finalmente, foi realizado estudo prospectivo comparando-se o volume uterino de 50 mulheres ao USTA e USTV. Para análise estatística utilizaram-se os testes t de Student e coeficientes de correla o de Spearman e Pearson. Resultados: correlacionando-se com a paridade, para P = 0 (n = 99) o volume foi de 44,4 cm3; para P = 1 (n = 72) o volume foi 58,5 cm3; para P = 2-3 (n = 137), o volume foi 75,8 cm3; para P = 4-5 (n = 56), 88 cm3 e para P = 6 ou mais (n = 26), 105 cm3, mostrando uma correla o positiva entre a paridade e o volume uterino. Com o coeficiente de correla o de Spearman obtiveram-se r = 0,59 e p = 0,001; o coeficiente de correla o de Pearson foi r = 0,55 e o mesmo p. N o houve varia es significantes do volume uterino ao USTA e USTV. Conclus es: o útero aumenta com a paridade e sofre altera es do seu volume com a idade, sendo essas modifica es detectadas ao USTA. Ambos os métodos (USTA e USTV) s o equivalentes na medida do volume uterino; entretanto, a reple o vesical ao USTA permite melhor avalia o do comprimento uterino.

Abstract: OBJETIVO: Analisar variáveis clínicas e ultra-sonográficas, como presen a ou ausência de barro biliar, espessura da parede e medida transversal da vesícula biliar, idade, paridade, presen a ou ausência de diabetes mellitus associadas a litíase vesicular assintomática, bem como determinar a sua prevalência em pacientes submetidas ao exame ultra-sonográfico. MATERAIS E MéTODOS: Foram analisadas, em estudo prospectivo, 265 pacientes do sexo feminino, atendidas na Escola de Ultra-sonografia e Reciclagem Médica de Ribeir o Preto, durante o período de janeiro a setembro de 2001. RESULTADOS: Evidenciou-se diferen a estatisticamente significativa relacionada à litíase da vesícula biliar e espessura da parede da vesícula biliar, barro biliar, diametro transverso da vesícula biliar, faixa etária, paridade, passando de 4,1% nas nulíparas para 39,1% nas multíparas e diabéticas. A prevalência de litíase na vesícula biliar em pacientes assintomáticas foi de 14,7%. CONCLUS O: A litíase vesicular assintomática em mulheres ocorre principalmente com o decorrer da idade e da paridade. Os achados ultra-sonográficos mais freqüentemente encontrados foram presen a de barro biliar e de espessamento da parede da vesícula biliar.

Abstract: purpose: to determine the accuracy of transabdominal ultrasound (taus) in revealing physiological and pathological changes in uterine volume, and to compare uterine volume detected by taus and by transvaginal ultrasound (tvus) in an attempt to determine the relationship between the two methods. methods: a total of 1,186 pelvic echographic examinations (taus and tvus) were first reviewed retrospectively in terms of the major diseases and indications for the examinations. a total of 480 taus examinations without uterine disease were then selected and uterine volume was correlated with age and parity. finally, a retrospective study was conducted to compare the uterine volume of 50 women obtained by taus and tvus. data were analyzed statistically by student's t-test and spearman and pearson correlation. results: correlating with parity, volume was 44.4 cm3 for p = 0 (n = 99), 58.5 cm3 for p = 1 (n = 72), 75.8 cm3 for p = 2-3 (n = 137), 88 cm3 for p = 4-5 (n = 56), and 105 cm3 for p = 6 or more (n = 26), showing a positive correlation between parity and uterine volume. calculation of spearman's correlation coefficient yielded r = 0.59 and p = 0.001 and calculation of pearson's correlation coefficient yielded r = 0.55 and the same p value. there were no significant differences between the uterine volumes detected by taus and tvus. conclusions: the volume increases with parity and changes with age, and these modifications are detected by taus. the two methods (taus and tvus) are equivalent in determining the uterine volume; however, when taus is used, bladder filling allows a better evaluation of the uterine length.

Abstract: the objective of the present review study was to present the principal applications of magnetic resonance imaging (mri) of the chest, including the description of new techniques. over the past decade, this method has evolved considerably because of the development of new equipment, including the simultaneous interconnection of phased-array multiple radiofrequency receiver coils and remote control of the table movement, in addition to faster techniques of image acquisition, such as parallel imaging and partial fourier acquisitions, as well as the introduction of new contrast agents. all of these advances have allowed mri to gain ground in the study of various pathologies of the chest, including lung diseases. currently, mri is considered the modality of choice for the evaluation of lesions in the mediastinum and in the chest wall, as well as of superior sulcus tumors. however, it can also facilitate the diagnosis of lung, pleural, and cardiac diseases, as well as of those related to the pulmonary vasculature. pulmonary mri angiography can be used in order to evaluate various pulmonary vascular diseases, and it has played an ever greater role in the study of thromboembolism. because cardiac mri allows morphological and functional assessment in the same test, it has also become part of the clinical routine in the evaluation of various cardiac diseases. finally, the role of mri has been extended to the identification and characterization of pulmonary nodules, the evaluation of airway diseases, and the characterization of pleural effusion.
