Abstract

Background: A bone scan or commonly referred to as bone print is nuclear medicine examination using a radioactive substance or radiopharmaceutical that is inserted into the body through intravenous injection which aims to help diagnose abnormalities that occur in the bone. This imaging procedure uses a radiopharmaceutical 99mTc-MDP (methylenediphosphonate) is the most commonly used radiopharmaceutical.Methods: The patient will be injected with this radiopharmaceutical at a dose of 15-20 mCi, through the vein in the hand. Imaging can be done as soon as the radiopharmaceutical is injected or after a while to wait for the radiopharmaceutical to be distributed and absorbed by the bone, about 3-5 hours later. Imaging is done by three-phase method, namely the first phase (Vascular phase), the second phase (Blood Pool phase), and the third phase (Total body phase) l.Results: The bone scan method is an efficient examination because in 1x the imaging can provide a complete picture from the head to the foot. Evaluation of results, under normal conditions the distribution of radioactivity in the bone appears symmetrical.Conclusion: In the process of bone metastasis, it can be seen that typical pathological radioactivity can be multiple (multiple hot spots). Malignant tumors can be distinguished from benign tumors by blood pool examination.

Abstract

Background: In the treatment process of patients covid-19 thorak photo action is done periodically every three days, the average length of hospitalization of covid patients in the isolation room at least 9 days and or up to the results of negatip swab tests and normal thorak photo images. The purpose of the study was to analyze the effect of hospitalization days and the frequency of action on the amount of radiation absorption dose received by Covid-19 patients in Covid-19 isolation rooms, as an evaluation material to improve aspects of occupational safety and health in the environment and society (patients).Methods: Design observational research with a cross-sectional approach. The population of all Covid-19 patients in isolation rooms at RSU Karsa Husada is 200 people. A sample of 200 respondents with probability sampling techniques. Independent variables are the length of hospitalization and frequency of thoracic photos. The dependent variable is the average dose of radiation absorption in the patient.Results: The results showed no long-standing effect of hospitalization on the average dose of radiation absorption in patients (p-value 0.030) and there was a effect on the frequency of thorax photos against the average dose of radiation absorption in patients (p-value 0.000).Conclusions: This research can be developed using more specific variables and with a larger population as well as more variation.

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

Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan kapasitas masyarakat dalam pengelolaan data kependudukan berbasis sistem informasi melalui program “Kampung Smart” di Kecamatan Tembalang, Kota Semarang. Masalah yang dihadapi adalah masih terbatasnya penggunaan teknologi informasi dalam mendukung kegiatan preventif berbasis data. Metode yang digunakan meliputi tahapan persiapan, pelatihan, implementasi sistem, serta evaluasi melalui survei dan diskusi kelompok terfokus (FGD). Hasil menunjukkan bahwa sistem informasi ini membantu mempercepat pencatatan dan pelaporan data warga, serta meningkatkan kesadaran masyarakat akan pentingnya kesehatan preventif. Tingkat kepuasan masyarakat mencapai 97,4%. Kegiatan ini membuktikan bahwa kolaborasi antara teknologi dan literasi masyarakat dapat mendorong transformasi digital pada level komunitas.
