Background: The imaging for vein vessels or Magnetic Resonance Venography (MRV) has own role and advantages on MRI examinations, specifically for evaluating intracranial blood vein circulation. MRV generally uses Phase Contrast (PC) method and  PC-MRV imaging, there is an  important parameter to be considered, its velocity encoding or VENC. VENC is selected before the examination and has to be adjusted  the anticipated blood flow velocity in the examined organs. The right selection of VENC will result in optimum intracranial vessels images and accurate diagnose. The aim of this study is to figure out if there is significant effect of VENC on anatomical information of brain MRV and to find out which VENC the best  intracranial veins demonstrates.Methods: This research was a quantitative study with quasi – experimental approach. Data were obtained from five healthy volunteers who were scanned by using a 3 Tesla MRI device in Radiology Department Siloam Lippo Village Hospitals. Each volunteer was scanned with five VENC variations: 10 cm/s, 15 cm/s, 20 cm/s, 25 cm/s, and 30 cm/s. The MRV images were assessed by two radiologist as the respondent. The Data were analyzed by simple linear regression test and Friedman test.Result: The results showed that there was significant effect of VENC on anatomical information of brain MRV, with significant value below 0,001 (p value 0,05). Mean rank on Friedman test showed that the best VENC to demonstrate intracranial veins was 25 cm/s.Conclution: There was a significant effect of VENC on anatomical information of brain MRV with the VENC of 25 cm/s gave the best image of intracranial veins in general.

Background: Magnetic Resonance Spectroscopy (MRS) is an advance examination of MRI which produces a spectra describes metabolic information of tissues. ROI setting was very important in producing the spectra with diagnostic value that called Full-Width at Half Maximum (FWHM). In clinical applications, Radiographers select several ROIs in obtaining FWHM values without any specific benchmark which in turn directly affects on the accuracy of staging brain tumor. This study aims to examine the FWHM profiles based on the ROI selections, and to determine the effect of selected ROIs to FWHM values.Methods: This research was a quantitative study with an experimental approach. Data were assessed by an expert Radiographer during a period of 30 days on June 2016 in Radiology Department of Siloam Kebon Jeruk Jakarta Hospital using a specific bottle phantom MRI 2000 ml. The phantom was scanned with 1.5 Tesla MRI scanner, wuth various selection of the ROIs sized 20 mm, 25 mm, 30 mm, 35 mm and 40 mm at the centre position, 12 o'clock position, 3 o'clock position, 6 o'clock position and 9 o'clock position. Data was analyzed using linier regression test of SPSS V.16 software. The confident interval of influence of the ROI size in producing FWHM values was 95%.Results: The results showed the optimum FWHM values, 12-20, produced from the ROI size of 20-30 mm at the centre position. Regression analysis showed significant result (p-value 0.05), which was null hypothesis was rejected. It can be concluded that the ROI size setting effected on the resulted  FWHM values. The smaller ROI size, FWHM value will decrease with higher homogeneity and vise versa.Conclusion: Optimum FWHM value was produced by ROI size of 20 – 30 mm at the centre position. There was influence of ROI size setting to FWHM value.

Introduction: Ultrasound screening for foetus congenital malformations is the mainstay in diagnosis and is commonly performed at 19-22 weeks gestation. Magnetic Resonance Imaging (MRI) is known as a problem solving tool which is used for answering a specific question. Both ultrasound and foetus MRI are highly sensitive and specific in diagnosis of congenital anomalies of the foetus with high agreement between both modalities. Aim: To determine the accuracy of Ultrasound Sonography (USG) and High Field 3 tesla MRI in diagnosis of different types of foetal Central Nervous System (CNS) and non CNS congenital abnormalities. Materials and Methods: A cross-sectional study was conducted in the Department of Radiodiagnosis at Agartala Government Medical College and GB Pant Hospital from June 2017 to May 2019. A total of 65 cases with ultrasound diagnosis of foetus abnormalities were examined by 3 Tesla MRI. MRI were performed within 15 days after USG detected anomalies. Statistical analysis was done using Chi-square test. Results: In cases with foetus anomalies high field MRI provided detailed findings leading to a more refined diagnosis. CNS anomalies were more as compared to other anomalies. Some of the antenatal findings were confirmed in some cases following termination of pregnancy and some were by postnatal examination. Among them chest anomalies was least common i.e., 1.5%. sensitivity of MRI was 88.13%, specificity was 66.66%, Positive Pressure Ventilation (PPV) was 96.29%, Negative Predictive Value (NPV) was 36.36% and USG sensitivity was 82.43%, specificity and 77.77%, PPV was 95.83%and NPV was 41.17%. Conclusion: High field MRI should be used as a second line of investigation in patients with foetus abnormalities diagnosed by ultrasound for confirmation of diagnosis and selecting the treatment protocol. In cases of fatal abnormalities, a confirmed diagnosis made before 20 weeks of pregnancy may help by terminating the pregnancy.

The government has issued a new normal policy with the aim that people can continue to live productively by changing their lifestyle so as to prevent the transmission of COVID-19. One of the measures to prevent and manage COVID-19 is to increase immunity. Online seminars are one of the most important health promotion methods and can be done in the new normal era. This study aims to determine the effect of online seminars on the knowledge and perceptions of the general public. This study used a quasi-experimental pre and post-test design. The sample in this study were all participants who attended online seminars and filled out the pretest and posttest questionnaires. Univariate data analysis shows that the majority of respondents have a mean age of 29.41 years, most of them are women (58.8%), and are students or have not worked (44.7%). Most of the respondents had a good level of initial knowledge about increasing immunity in the face of COVID-19 (68.4%) and a sufficient level of perception of the new normal (49.1%) before attending online seminars. The bivariate data analysis shows that there is a significant increase in knowledge about increasing immunity in the face of COVID-19 in the new normal before and after attending an online seminar with a p-value = 0.000 (p-value <0.05). Online seminars are the right way to promote health in increasing knowledge about immunity to deal with COVID-19 and perceptions of the new normal in ordinary people.

Various adolescent health problems in Indonesia are so complex, not only related to physical but also related to psychosocial aspects. When teenagers have to struggle to recognize the sides of themselves that are experiencing physical-psychic and social changes due to puberty, society instead tries to hide everything about sex and leave teenagers with question marks in their minds. The view that sex is taboo, makes teenagers reluctant to discuss reproductive health with others. The lack of accurate and correct information about reproductive health makes teenagers seek access and explore themselves. Health education for adolescents needs to be provided with the right methods and media. Audiovisual media is a learning tool or media that uses video or mobile display, this media is a modern learning among the community and effective for teenagers so that they can absorb the material provided to the maximum.This study aims to determine the influence of audiovisual media on increasing adolescent knowledge about reproductive health. This research is a quantitative study with quasi-experimental design one group without control, with a sample of 50 respondents. Respondents measured the rate ofyears before and after intervention, namely health education using audiovisual media.The results of the study: dependent t-test dependent statistical test on post-test knowledge about reproductive health increased by 6.46 to 8.06 with p value of 0.000 indicating the influence of audiovisual media provision on improving adolescent reproductive health knowledge.
