Evaluation Comparison Image Quality of Breath Hold (SSTSE) and Respiratory Triggering (TSE) Technique to the Examination of Magnetic Cholangiopancreatography (MRCP)

Abstract

Background : Magnetic resonance cholangiopancreatography (MRCP) is MRI examination to visualize to visualize a disorder in part biliary or of the human bile. The artefact in the image MRCP is often happened due to the movement of respiratory system. Purpose : This study to compare the better image quality between Breath Hold (SSTSE) and Repiratory Triggering (TSE)techinques. Methods : This study used observational analytic study with prospective approach. 16 samples were examined with two techniques SSTSE and TSE respectively in order to get 3D MRCP image. The Signal to Noise Ratio (SNR) and Contrast to Noise Ratio (CNR) is measured to evaluate the image quality. Result: The SSTSE technique only has a higher SNR in gallbladder meanwhile the TSE technique has a higher SNR in pancreatic duct. The higher CNR is got using TSE technique. Conclusion : The TSE showed the higher SNR in pancreatic duct and the higher CNR is got with SSTSE technique. The recommendation technique for evaluating pancreatic duct is respiratory triggering.

Increased Myopia Prevalence in Youngsters as a Result of Online Learning

“…Indonesia has the highest prevalence of refractive errors among all eye diseases, with refractive defects affecting 25 % of the population, or over 55 million peoples (Suroiyah et al, 2017). North and South Sulawesi placed third in Indonesia with the greatest frequency of blindness, at 0.8 % population, according to the 2013 Basic Health Research (Riskesdas).…”

Synthesis of manganese nanoparticles of Oolong tea extract by sonication method for a natural oral contrast media on magnetic resonance cholangiopancreatography

“…Several studies to find the alternatives to natural negative oral contrast media in Magnetic Resonance Cholangiopancreatography (MRCP) examination have been carried out, in the form of liquid or juice, both in fruits and tea drinks, which contain a lot of manganese (Mn) (1). A study on fruits as an alternative to natural negative oral contrast media, and their Mn content is blueberry (3-4 mg/dL) (2,3), pineapple (0.276 mg/dL) (4,5), blackberries (2.93 mg/dL) (6), lemon or orange (0.2 mg/dL) (7), and black tea (0.44 mg/dL) (8).…”
