“…A particular concern in performing imaging using ionizing radiation on pregnant patients or breastfeeding lies in the potential risk to the fetus is exposed 17 . However, we must also take into account whether the mother's medical condition is life-threatening and the exam will help in its survival and in this case the fetus will also have a direct benefit 18 .…”

Review Article IRJOP (2018) 1:3 The influence of radiation x germ cell and embryonic fetal development Objective: In this article the effects generated by ionizing radiation are discussed more precisely by X-rays, in the cells of gametic line and in embryonic/fetal development, when there exposition without proper protection for this type of energy. Methodology: The method used for preparation of this work was the literature review of scientific papers, theses and magazines found in the databases already available. Results and Discussion: Based on the literature review carried potential risks were analyzed and importance of radiation protection, in addition to their negligence consequences.

“…Symptomatic patients with bifascicular block and advanced AVB have been treated with temporary or permanent pacemakers during pregnancy. Advanced AVB was found in 0.02% of a series of 92000 pregnancies 3,4 . It may be diagnosed in asymptomatic patients by means of the findings of an electrocardiogram required for other reasons, or it may manifest with clinical complaints such as dyspnea, presyncope and syncope.…”

“…Radiation exposure represents a relevant factor to be taken into consideration in abdominal CT studies. Although there is no defined value for maximum radiation dose to which a patient could be exposed, and there is a consensus that this patient should receive the dose required for the diagnosis, it would be desirable that this dose was as lowest as possible (32) . The dose utilized for each phase of multislice abdominal CT is about 12 to 20 mSv (33) .…”

OBJECTIVE: To determine the role of the unenhanced phase of abdominal computed tomography in patients without a definite diagnosis or undergoing tumor staging. MATERIALS AND METHODS: A prospective and transversal study was developed with 100 consecutive patients submitted to unenhanced and contrastenhanced abdominal computed tomography. Two observers evaluated all the computed tomography images in the contrast-enhanced phase (first analysis) and, later, in the unenhanced phase (second analysis) in an attempt to establish the primary and secondary diagnoses as a function of the clinical indication for the study. The frequency of changes in the diagnoses resulting from a combined analysis of the images in the pre-and post-contrast phases was evaluated. Cases with changes in the diagnosis were reviewed by clinical specialists for determining possible changes in the therapeutic approach. RESULTS: Primary and secondary diagnoses were changed in respectively 1 and 18 cases (p = 1.000; p = 0.143) as follows: steatosis, adrenal nodules, nephrolithiasis, renal cysts and hepatic calcification. In the cases where the unenhanced phase changed the diagnosis, the specialists changed the therapeutic approach in 14 of the 19 patients (73%) (p = 0.038). CONCLUSION: No significant change was observed in the primary or secondary diagnosis as a result of the findings in the unenhanced phase. However, changes in secondary diagnoses affected the therapeutic approach adopted by the specialists. Keywords: Computed tomography; Contrast media; Abdomen.OBJETIVO: Determinar o valor agregado da fase sem meio de contraste da tomografia computadorizada do abdome em pacientes sem diagnóstico determinado ou em estadiamento tumoral. MATERIAIS E MÉTODOS: Estudo prospectivo e transversal em 100 pacientes consecutivos submetidos a tomografia computadorizada abdominal sem e com meio de contraste intravenoso. Dois examinadores avaliaram todos os exames, procurando estabelecer, através da fase com meio de contraste intravenoso (primeira análise) e posteriormente através da fase sem contraste (segunda análise), o diagnóstico principal e os secundários em função da indicação clínica do exame. Mediu-se a freqüência de mudança diagnóstica decorrente da análise combinada das fases pré-e pós-contraste intravenoso. Casos que tiveram mudança diagnóstica foram avaliados por especialistas clínicos para determinar se implicaria mudanças de conduta. RESULTADOS: Diagnósticos principal e secundário foram modificados em 1 e 18 casos, respectivamente (p = 1,000; p = 0,143). Os diagnósticos modificados foram: esteatose, definição de nódulo em adrenal, nefrolitíase, classificação de cistos renais e calcificação hepática. Nos casos em que a fase sem contraste modificou o diagnóstico, os especialistas mudaram sua conduta em 14/19 (73%) dos pacientes (p = 0,038). CONCLUSÃO: A fase sem contraste não modificou significativamente o diagnóstico principal ou secundário. Porém, as mudanças nos diagnós-ticos secundários influenciaram na conduta adotada pelos especialistas. Unite...
