Backgroud: blurring artifact is an issue in axial cervical MRI using T2 Turbo Spin Echo (TSE) weighted Cartesian. T2W TSE BLADE is potential to substitute its shortcomings. This study aims to analyze the image quality and artifacts between T2W TSE Cartesian and T2W TSE BLADE on axial cervical MRI examination and to determine the better sequence in producing image quality.Methods: this is a quantitative research with descriptive approach. 7 volunteers were scanned for cervical axial examination with T2W TSE, T2W TSE Cartesian and T2W TSE Blade. Images were processed in MathlabTM. SNR of intervertebral disc, spinal cord and CSF were measured using ROI. Image resolution were find out from pixel spacing in DICOM info. Blurring artifact were analyzed by comparing the signal of blurred area to the background noise. Data were analyzed using descriptive statistics.Results: SNR of T2W TSE Cartesian and T2W TSE BLADE were 22,144 and 17,532 (intervertebral disc), 20,952 and 16,786 (spinal cord), and 16,717 and 12,883 (CSF) respectively. Image resolution (mean) were 0,391 pixel/mm (T2W TSE Cartesian) and 0,625 (T2W TSE BLADE). Blurring artifact were 8,161 (T2W TSE Cartesian) and 6,826 (T2W TSE Blade).Conclusion: T2W TSE Cartesian was superior in pixel intensity and SNR, while the blade technique was superior in terms of spatial resolution and artifacts reduction. Thus, it is recommended to be applied in clinical field if the SNR or image detail is the priority.

Background: In MR angiography examination of the brain, there are many clinical situations where radiologist want to optimal suppression of stasionary nuclei. So stasionary nuclei and flowing nuclei will produce a good contrast. One of the most commonly used method MR angiography of the brain is a 3D TOF because it can show the blood vessels by hyperintens with more hypointens of background. Parameters TR and flip angle is one of the parameters that will determine a stasionary nuclei experiencing suppression well and the flowing nuclei will still generate a signal that more hyperintens. The porpose of this study was to determine the influence of repetition time and flip angle of the anatomical information of 3D TOF MRA examination of the brain, and also to determine value the repetition time and flip angle best to display anatomical information of 3D TOF MRA examination of the brain. Methods: This research is an experimental approach to the pre-experimental research design and post-test only research design. This research was conducted in Bintaro Premier Hospital. The data in the form of 54 3D TOF MRA images brain of 6 volunteers with nine variations repetitions time and flip angle. Assessment anatomical information performed by the two respondents or reviewer. The data analysis is done by testing the influence is multiple linear regression to determine the value of repetition time and flip angle optimal use friedman mean rank test. Result: The result showed that there is the influence of repetition time and flip angle of the anatomical information on 3D TOF MRA examination of the brain with a significance level of p <0.001 (p <0.05). The repetition time 30 ms and flip angle 30o is and optimal value for anatomical information showing 3D TOF MRA examination of the brain. application of repetition time 30 ms and flip angle 30o can be properly saturate or suppression the stasionary nuclei so that is displays excellent contrast between the nuclei. Conclution: There are influence of repetition time and flip angle to the anatomical information on 3D TOF MRA examination of the brain with a significance level of p <0.001 (p <0.05). The repetition time 30 ms and a flip angle of 30o is an optimal value for anatomical information showing 3D TOF MRA examination of the brain.

Background: Aliasing artifacts often occur on MRI examinations Orbita sequence T1 SE Fat Saturation sagittal oblique slices. One way to eliminate aliasing artifacts is by setting Phase Oversampling (PO). The purpose of this study was to determine differences in anatomic information and image quality in the T1 SE sequence of oblique sagittal fat saturation slices with PO variations of orbital MRI examinations and to determine the value of PO variations that can produce optimal anatomic information and image quality in the sequences of T1 SE Fat Saturation slices sagittal oblique on Orbita MRI examination. Method: This type of research is quantitative research with an experimental approach. The research subject is Orbita MRI imagery. The research sample consisted of Orbita MRI images obtained from 10 volunteers. Data obtained from SNR and CNR measurements to obtain image quality data, then the image results were assessed by respondents using questionnaires to obtain anatomic information data. The data obtained were analyzed using different tests in the SPSS application. Results: The results showed that there were significant differences in the anatomy of the lens with aliasing artifact variations in PO 13%, while PO 52% and 91% had no aliasing artifacts. Optic nerve anatomy has a clear and well-defined image at PO 91% compared to PO 13% and 52%. Friedman test results on anatomic information on the anatomy of the Lens, superior Muscle rectus, and Optic nerve are significant with p-value <0.05, meaning there are differences in anatomic information with variations in PO. Friedman anatomy test results of Retro orbit, Muscle rectus inferior, and Vitreous are significant with p-value> 0.05, meaning there is no difference in anatomic information with variations in PO. Furthermore, the results of the study showed that there were differences in image quality (SNR and CNR) against PO variations with significance values (p <0.05). Conclusion : Based on the calculation of the mean rank Friedman test shows that the more the PO value increases, the quality (SNR and CNR values) increases. The PO 91% setting produces a more optimal image.

Background : Examination procedure of Magnetic resonance imaging (MRI) Brain Perfusion in patient with tumor disease at Radiology Department of National Brain Hospital used the MR Perfusion sequence with the Dynamic Susceptibility Contrast (DSC) method with the addition of Arterial Spin Labeling (ASL) method which was also used to determine CBF values. Nevertheless CBF values can also be obtained from the use of the DSC method. The application of these two roles in patient with tumor disease certainly has their respective roles in providing accurate information for the diagnosis. The purpose of this study was to determine the role of the application of MR perfusion with the Arterial Spin Labeling (ASL) method and the Dynamic Susceptibility Contrast (DSC) method for the diagnosis of patient with tumor disease at Radiology Department of National Brain Hospital. Methods :The type of this research is qualitative with case study approach. The data were collected from March – April 2019 at at Radiology Department of National Brain Hospital by using observation method, interview with radiology specialist doctor, sending doctor, FGD, and documentation. Data obtained from the study were analyzed by making the transcript then reduced in the form of categorization table and open coding, presented in quote form and then can be drawn conclusion. Result : Brain perfusion MRI examination procedures in tumor patients begin with examination preparation, preparation of tools and materials, carry out the examination using the MRI Brain protocol with contrast and without contrast. The use of contrast uses the Dynamic Susceptibility Contrast (DSC) method and non-contrast use using the Arterial Spin Labeling (ASL) method where both complement each other to inform perfusion parameter values. Conclusion : The conclution of this study indicate still needed the application of both MR perfusion methods, namely the ASL method and the DSC method. The ASL method will provide additional information in the form of absolute values of Cerebral Blood Flow that are not affected by permeability, besides that the DSC method is able to provide Cerebral Blood Volume values that are used as a parameter of Perfusion MR evaluation.
