Hepatitis is inflammation of the liver due to viral or alcohol infection. Hepatitis can cause death and the case always increases every year both in Indonesia and the world. The aim of this study is to describe and evaluate the management of examination such as patient preparation procedure, tool preparation, patient position, transducer placement, transducer used, and ultrasound image of hepatitis. This research was conducted by qualitative descriptive method. The population is all patients who perform liver ultrasound examination at RSUD Cengkareng Jakarta. The samples used were patients who performed liver ultrasound examination with clinical hepatitis. The number of samples used is 2 patients. After being analyzed and observed, ultrasonography is an accurate and accurate examination of the hepatitis case. Additional scripting techniques are sometimes required in certain cases to make the results more optimal. Based on this research, it can be expected that ultrasound modalities can be used as an appropriate supporting tool in establishing clinical hepatitis with accurate, fast, cheap and safe results.
Loopography examination technique is a radiological examination technique in lower digestive tract (colon) by inserting a positive contrast media into the colon through an artificial hole in abdominal area. This examination aims to evaluate the anatomy and physiology function from distal section of colon to anus with ca colon clinical. This research was conducted in radiology installation of Tangerang District General Hospital during November to December 2018, using a qualitative descriptive method with a literature study approach and interview. The results found that loopography examination in Tangerang District General Hospital did not require special preparation. The kind of contrast media used is a water-soluble contrast media such as iohexol with a ratio of 1: 3 mixed with NaCl. This loopography contrast media can be inserted through the clean stoma or anal. The routine projections performed for loopography examination in Tangerang District General Hospital are Plan photos of Abdomen, Antero Posterior (AP) and Lateral. But sometimes Oblique projection is also used as an addition if is less obvious anatomy due to overlap/superposition.
Latar Belakang: Pemeriksaan lumbosacral sering kali menghasilkan kualitas citra yang kurang optimal. histogram equalization merupakan tahapan memanipulasi data citra digital untuk meningkatkan kualitas citra yang dapat diimplementasikan pada citra digital radiografi lumbosacral.Tujuan: Mengevaluasi peningkatan kualitas citra digital radiografi lumbosacral dengan menggunakan histogram equalization.Metode: Jenis penelitian ini adalah kuantitatif dengan pendekatan eksperimental. Jumlah sampel terdiri dari 1 Kyouku’s anthropomorphic phantom yang dibagi menjadi citra lumbosacral proyeksi antero posterior (AP) dan lateral sebelum dan setelah direkonstruksi menggunakan histogram equalization. Kualitas citra dinilai dengan analisis grafik histogram, pengukuran nilai signal to noise ratio (SNR) merupakan parameter untuk menentukan kualitas citra radiografi, dan visual grading analysis (VGA) oleh 10 orang radiografer dianalisis dengan menggunakan Uji Wilcoxon Signed-Rank.Hasil: Hasil kualitas citra menunjukkan bahwa analisis grafik histogram memiliki visual kecerahan yang meningkat, grafik histogram terdistribusi merata, dan nilai SNR meningkat setelah direkonstruksi dengan metode histogram equalization. Hasil VGA dengan menggunakan uji wilcoxon Signed-Rank setelah direkonstruksi kembali dengan metode histogram equalization pada proyeksi AP menunjukkan nilai 0,005 dan proyeksi lateral 0,074 dengan p-value > 0,05.Kesimpulan: Terjadi peningkatan kualitas citra radiografi proyeksi AP dan lateral dengan menggunakan metode histogram equalization.
Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) is a cause of sudden cardiac death in otherwise healthy young adults. (ARVD/C) is an inherited cardiomyopathy characterized by life-threatening ventricular arrhythmias and slowly progressive ventricular dysfunction. To diagnose ARVC is indicated by the Task Force of ARVC criteria in 1994 and then revised in 2010 set by the WHO/ISFC. To identify clinical characteristics of ARVC using CMR. The design of this study was qualitative descriptive, which was done by the observational method using MRI 1.5 Tesla. The subject was an adult patient who did Cardiac MRI examination in National Cardiovascular Centre Harapan Kita in March 2018. The collected data were diagnostic images of CMR sequence. Then, it compared with the diagnostic criteria of ARVC which was indicated by Task Force. The result of this study of several ARVC diagnostic criteria in Cardiac MRI examination with T1 Black Blood sequence is clear and accurate in indicating the presence of fat infiltration, CINE sequence is clear in visualizing the dilatation in the right ventricle, wall motion abnormalities, accordion sign, bulging, and LGE clearly shows fibrosis. The detection of right ventricular enlargement, fatty infiltration, fibrosis, and wall motion abnormalities in CMR is useful in the diagnosis of ARVC.
This study discusses the effect of variations in exposure index or exposure index (EI) on subjective image quality assessment on lumbosacral radiographic examination. The method used in this research is descriptive quantitative which is done by filling out questionnaires and calculating the radiation output dose. Then to draw conclusions, perform a visual grading analysis (VGA) statistical test using the one-way ANOVA test. The results obtained by varying the EI for AP projections of 2.99 (overexposed), 2.79 (optimal), and 2.33 (underexposed) then for Lateral projections of 2.91 (overexposed), 2.76 (optimal), and 2.46 (underexposed). Furthermore, the dose calculation using the radiation output equation produces 3.158 mGy (overexposed), 0.78 mGy (optimal) and 0.57 mGy (underexposed) for the AP projection while for the lateral projection it produces a radiation dose of 3.61 mGy (overexposed), 1.52 mGy (optimal). , and 0.78 mGy (underexposed). Then to get a conclusion, VGA test was carried out using ANOVA testing, the data generated after performing ANOVA tests on AP and lateral projections showed results of 0.87 and 0.612. Based on the ANOVA results that have been carried out, it can be concluded that all respondents have the same assessment of the quality of the lumbosacral image subjectively or visually, there is no significant difference between each image but has a different EI value, but images with an overexposed EI value have a different image. better than the other two EI indicators.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
