Background : Before conducting an MRI examination, there will be a positioning. One of the positions carried out is the placement of isocenter. Isocenter is a magnetic center point where each gradient will be centered at that midpoint (Brown and Semelka, 2010). Different isocenter placements can affect image quality (Caramanos et al, 2010). In practical experience in the Telogorejo Semarang SMC Hospital, the placement of the isocenter in the nation while in Dr. Soetomo and Premier Surabaya Hospital placed Isocenter in Glabella. To examine the effect of isocenter placement on image quality and MRI brain T1 fast spin echo anatomical image information in the nasion and glabella and determine the optimal isocenter placement between the nasion and glabella. Method : This type of research is quantitative with an experimental approach. This research was conducted at Telogorejo SMC Hospital Semarang. Data in the form of 16 MRI images of sagittal brain pieces of T1 Fast Spin Echo weighting on isocenter placement in the nasion and glabella of 8 volunteers. Testing is done using the SPSS program where the image quality is analyzed by linear regression test, while for anatomical image information is analyzed by the Wilcoxon test. Result : The results of this study indicate that there is an effect of isocenter placement on the quality of MRI brain images of T1 fast spin echo sagittal pieces as seen from p value SNR (0.039) and CNR (0.010) <0.05 and from SNR percentage effect of 16.85% while CNR of 5, 8%. in addition to the influence, there are also differences in the anatomical image information of the MRI brain T1 fast spin echo sagittal section which is seen from the p value generated is 0.001 <0.05. Conclusion : Judging from the mean rank per anatomy, isocenter placement in the nasion is optimal in providing information on the mesencephalon, medulla oblongata, and cerebral subarachnoid space.

Background : Chronic rhinosinusitis is defined as inflammation of the nose characterized by two or more symptoms, one of which should be either obstruction, facial pain pressure, reduction of smell for more than 12 weeks. Multiplanar reconstruction is a computer program that can create coronal, sagittal, and paraxial images from a stack of contiguous transverse axial scans. There are several parameters that support CT-Scan image quality, one of which is slice thickness. The slice thickness is an incision where the value chosen by the operator is in accordance with clinical requirements. The purpose of this research is to find out difference of image anatomic information in coronal ct scan paranasal sinuses with reformat slice thickness variations in chronic rhinosinusitis and the optimal reformat slice thickness. Method : This type of research is an experimental quantitative that was located in the Radiology Installation of dr. Moewardi Hospital Surakarta on March-May 2019. This research used 8 samples and 3 respondents, where slice thickness coronal was reformatted with variations 1 mm, 1,5 mm, 2 mm, 2,5 mm, and 3 mm. Anatomical criteria assessed were nasal septum deviation, mucosal thickening, and concha bullosa. In this research, Kappa test was conducted to determine the degree of allignment between respondents. Then analyzed by Friedman test to determine difference of image anatomic information in coronal ct scan paranasal sinuses with reformat slice thickness variations in chronic rhinosinusitis and to find out which the optimal reformat slice thickness by looking at the highest mean rank. Result : The results of this research showed a significant difference between the use reformat slice thickness variations to the anatomy criteria with p value < 0,05. Reformat slice thickness 1 mm seems very clear on nasal septum deviation, mucosal thickening, and concha bullosa, 1,5 mm and 2 mm seems very clear on nasal septum deviation and mucosal thickening, 2,5 mm seems very clear on nasal septum deviation, 3 mm seems very clear on nasal septum deviation and concha bullosa. Conclusion : Based on the result that there is a difference of image anatomic information in coronal CT-Scan paranasal sinuses in chronic rhinosinusitis with the most optimal reformat slice thickness is 1 mm.

Background: Brachytherapy is a radiation treatment by bringing radiation sources closer to the primary tumor which aims to provide additional therapeutic doses (booster) after external radiation administration so that the optimal dose will be achieved. In general brachytherapy uses closed radioactive sources namely Radium, Cobalt-60, Cesium- 137, and Iridium-192.Intracaviter technique is a type of brachytherapy technique in which the radiation source is placed in a hilt and inserted into a body organ that contains a tumor. to obtain the optimal dose distribution. Methods: The type of research used is qualitative research with a case study approach. The study was conducted by observation, documentation and interviews. The subjects of this study were one radiation oncology specialist, one medical physicist, one radiotherapy radiographer, and one radiotherapy nurse at the Radiotherapy Installation of Dr. Moewardi Hospital. Stages The data analysis in this study used the data analysis method which was done descriptively using interactive models. Results: The results showed that the management of radiotherapy in cervical cancer patients at Radiotherapy Hospital Dr. The procedure consists of several procedures, namely the control of a specialist oncologist of radiation after external radiation, supporting examinations (check vital signs, laboratory, ECG, and chest X-ray), undergoing hospitalization a day before irradiation of brachytherapy, spinal anesthesia before applying the applicator, applying an applicator, simulating the position of the applicator with AP and Lateral x-ray projections, calculating the dose (2 x 850 cGy) and irradiation time in the TPS (Treatment Planning System) room based on the Manchester system dose distribution, and irradiation in the brachytherapy room. Conclusion: Management of brachytherapy consists of several procedures, namely the control of radiation oncology specialists, supporting examinations, undergoing hospitalization the day before exposure, spinal anesthesia, applying applicators, simulating applicator positions, calculating doses and exposure time in the TPS (Treatment Planning System) ) based on the Manchester system dose distribution, and carried out irradiation in the brachytherapy room. The reason for using three Co-60 sources in one fraction of brachytherapy irradiation is because it can shorten the irradiation time and minimize the time error arising when the source moves. Evaluation of Co-60 brachytherapy patients in cervical cancer cases can be estimated in the form of tumor response, in patients experiencing total response and not experiencing side effects such as cystitis or progitis.

Background :The cervical vertebrae consist of seven vertebral bones separated by intervertebral discs and connected by complex ligamentous tissue. Examination of cervical vertebrae includes Axial, Lateral, RPO and LPO AP projections. Axial AP projections are carried out with15-200 cephalad angles. At PKU Muhammadiyah Hospital Gamping vertebrae radiographic examination cervical AP projection was done without cornering this case there was a difference with the theory so the author wanted to know more about the examination procedure. Methods :This type of research is qualitative research with a case study approach. This research was conducted at the Radiology Installation of PKU MuhammadiyahGamping Hospital and was carried out in March - May 2018. This research was carried out by observation, documentation, radiogarfer interviews and radiology doctors.Results :The results of the study found that cervical vertebrae radiographic examination procedures in trauma cases used two projections, namely AP and Lateral projections. On vertebrae examination cervical projection of AP is done without cornering. The reason for not being cornered is because the radiograph has revealed the corpus, intervertebral disc, spinousprocesus. Cervical vertebrae examination with trauma cases requires further action. In the Radiology Installation PKU Muhammadiyah Hospital, Gamping, was assisted by the delivery of aerocom pneumatic tube system files, in its role this tool was very helpful if the sending doctor wanted to immediately find out the radiographic results of the patient with the trauma case.
