Abstract

Backgroud: Brain MRI examination generally has a long scanning time because many protocols that must be used, one of them is DWI sequences, which are sequences that can provide pathological information on the brain. One way to reduce scan time is to use parallel imaging sensitivity encoding (SENSE) techniques. SENSE utilizing the spatial information RF coil phased array to reduce the acquisition time by reducing the number of sampling lines K space therefore produce quality and good spatial resolution, but its has the limitations, namely the reduction of SNR. The purpose of this research was to analyze in SNR on  the variations of SENSE value in MRI brain DWI axial slices.Methods: This research is a quantitative study with an experimental approach in 15 patients MRI Brain. Data was taken by calculating the SNR value for the region of interest (ROI) in cortex cerebri, basal ganglia, thalamus, pons and cerebellum, and then ROI in noise background. Data was analyzed through Repeated Measures Anova test by comparing the differences in SNR values obtained in MRI brain DWI axial between the use of various SENSE values, that are 2.0; 3.0 and 4.0.Results: MRI image of DWI axial brain sequence with variation of reduction factor 2.0; 3.0 and 4.0 cause different SNR values. The highest SNR is found in the variation of 2.0 and the lowest value is 4.0 but the scan time is fastest at the 4.0 variation This is because there is a reduction in the phase encoding line in the K-space on each image using SENSE and the higher the reduction factor, the higher the reduction factor. SNR will decrease.Conclusion: The higher the value of SENSE variations will decrease the SNR value but the scan time is faster.

Abstract

Faktor penyebab urolithiasis atau batu ginjal diantaranya faktor geografis dan iklim. Urolithiasis juga lebih banyak terjadi pada daerah yang bersuhu tinggi dan area yang gersang/ kering dibandingkan dengan tempat/ daerah yang beriklim sedang. Iklim tropis, tempat tinggal yang berdekatan dengan pantai, pegunungan, dapat menjadi faktor resiko tejadinya urolithiasis. Daerah Banteran, tergolong ke dalam kawasan yang sejuk karena posisinya yang berada di bawah dari gunung slamet. Letak geografis demikian menjadikan masyarakat banteran termasuk ke dalam masyarakat dengan faktor resiko cukup tinggi untuk terkena batu ginjal. Pengabdian bertujuan untuk meningkatkan pengetahuan tentang deteksi dini bahaya penyakit batu ginjal (urolithiasis) dan pengobatannya. Metode kegiatan pengabdian masyarakat ini dilakukan dengan cara penyuluhan dan ceramah terkait materi tentang urolithiasis kepada masyarakat target, kemudian evaluasi dilakukan dengan menggunakan kuesioner pre-test dan post-tset untuk mengetahui tingkat penambahan pengetahuan masyarakat terkait urolithiasis. Hasil pengabdian menunjukkan adanya peningkatan pengetahuan tentang deteksi dini bahaya penyakit batu ginjal (urolithiasis) dan pengobatannya. Masyarakat sangat diperlukan mengedepankan dan menerapkan PHBS dalam kehidupan sehari-hari agar terhindar dari beberapa macam penyakit seperti batu ginjal.

Abstract

Background: Clinical vertebral tuberculosis (TB) occurs outside the lungs affecting the spine. It generally infects the spine in the lower thoracic and upper lumbar spine. MRI examination is performed on clinical vertebral TB patients to determine the degree of stress and changes in bone elements in the early stages of the disease. This study aims to analyze the lumbar MRI examination procedure in cases of suspected TB pleural effusion. Methods: This research was qualitative with a case study approach. Data collection was carried out at the Radiology Unit of Premier Bintaro Hospital with the methods of observation, interviews, and documentation. Data processing and analysis were carried out descriptively. Results: Lumbar MRI examination with suspected TB pleural effusion at the Radiology Unit of Premier Bintaro Hospital was not specially prepared, the patient was examined first through the patient checklist to avoid metal materials entering the examination room. Examination using the Non-Contrast Lumbar MRI protocol included of sagittal and coronal T2, sagittal T1, sagittal Short Tau Inverse Recovery (STIR), Myelography, Axial T2, and Axial T1. The results of the examination provided sufficient diagnostic information to indicate a vertebral TB lesion. Conclusions: The procedure for examining lumbar MRI in TB cases with suspected pleural effusion at the Radiology Unit of Premier Bintaro Hospital did not require special preparation, the examination protocol used was to provide TB clinical diagnostic information, the addition of Gadolinium contrast media could be an alternative choice.
