Abstract

Background: Multi-Slice Computed Tomography (MSCT) is diagnostic radiology examination that take an advantage of computer to acquire data and reconstructing an Image from number of detector rows. Noise is one of the tremendous factors that affect the quality of CT Images. Nowadays, CT mAs auto setting, an automatic exposure device, resolves such the Noise problems in which maintains the quality of diagnostic Images for all parts of the body with a lowest possible dose. Since working devices based on the size of the patient's body attenuation automatically, reduction of radiation dose by 40% to 50% would be achieved. Yet, the larger patient’s body parts, the higher patient’s CTDIvol occurrence, which in turn affects on the Noise produced.  The purpose of this research is to define the difference in the value of Image Noise and dose whenever the MSCT procedure is employed with and without the auto mAs selection with regards to maintaining CTDIvol and Image Noise.Methods: This research was an experimental quantitative study with one shot case study and post-test only approaches. Data were collected on July 2016 in Radiology Unit of Prof. Dr. Margono Soekarjo Purwokerto Hospital. Noise values was measured on 20 mm region of interest (ROI) and the dose was calculated by the CTDIvol on the workstation monitor were collecting data from the head, thorax and abdomen water phantom of CT Images. Data was analyzed by SPSS 16 software using statistical tests of the paired t-test.Results: The results of this study statistically deemed significant as there were differences in Image Noise values such as head, thorax and abdomen water phantoms (value ρ - value 0.05). Similarly, figures about the CTDIvol comparison also showed different dose levels received by the phantoms when apply the CT procedures with and without auto mAs selection to the head, thorax and abdomen water phantoms (the head phantom: 50.69 mGy Vs. 60.28 mGy; the thoracic phantom: 3.88 mGy Vs. 7,98 mGy; and the abdomen phantom: 8.38 mGy Vs. 20.83 mGy respectively). Conclusion: There was a difference in production of the Image Noise and dose when apply the CT procedures with and without auto mAs selection to the head, thorax, and abdomen water phantoms. Lower dose tended to induce more Noise than higher dose, meanwhile patient’s dose leads to increase as well.

Abstract

Background : Intracerebral hemorrhage (ICH) is the brain parenchyma bleeding. The volume of intracerebral hemorrhage can affect mild to severe clinical symptoms due to increased intracranial pressure and it has a high risk of death. In addition, CT scan CTScan is a gold standard  on PIS examination. Methods : This was a quantitative research with experimental approach. There are two methods of volumetric hemorrhage calculation, namely automatic and manual method. Automatic Volume Method (SVE) is a volume calculation by computer software available on CT Scan tool with voxel calculation in HU value range. The manual method (Broderick) used is AXBXC/2 which is the multiplication of length (A), width (B) and height/thickness of bleeding slice (C) divided by 2. From the result, the volume differencewas tabulated and measured, then the normality and different test were done.Results : The sample consisted of 10 new bleeding patient data which then classified into small hemorrhage group, calculated volumes automatic(SVE) and manual(Broderick). volume calculations obtained different values of volume ranging from 0.37 cm³ to 10.01 cm³, the percentage ranged from 3% to 41%. The result showed a very significant difference value due to the different test Paired Samples T Test with significance value of 0.001 (p-Value 0.05). From the data, 8 patients with different percentage above 20%,with average 25% were PIS with irregular shape. And 2 patients with volume difference below 10% with average 6 % were Intracerebral Hemorrhage regular shape. Conclussions : There is a difference in the calculation of volumetric Intracerebral hemorrhage between the automatic volume method (SVE) and the manual method (Broderick). With a percentage average difference of average volume of 6% for regular shapes and 25% for irregular hemorrhage.

Abstract

Backgroud: 2D thick slab single shot fast spin echo (SSFSE) sequence in MRCP examination is a sequence of fast spin echo (FSE) which has a long turbo factor so that the time of acquisition in this sequence is longer than usual that will potentially cause image blurring. Parallel acquisition or SENSE technique is a technique used to reduce acquisition time and improve spatial resolution. The purpose of this study was to determine differences in anatomical information with and without parallel acquisition technique in 2D thick slab SSFSE sequences on MRCP examination.Methods: This research was an experimental study. This research was conducted by Philips 1.5 T MRI unit in dr. S Hardjolukito Yogyakarta Hospital. Data were 20 MRCP images from 10 normal volunteers with and without parallel acquisition technique on sequences of 2D thick slab SSFSE. Assessment of the images was conducted qualitatively in the form of respondents's assessment of the clearance of anatomical information includes the gallbladder, right hepatic duct, left hepatic duct, common bile duct, common hepatic duct, cystic duct, and the main pancreatic duct. Quantitative data analyzed by Cohen's Kappa test, cross tabulation, and Wilcoxon tests.Results: The result showed that there was a difference between the clearance of the overall anatomical information between 2D thick slab SSFSE sequences with and without parallel acquisition technique in MRCP with p = 0.000 (p-value 0.05), based on the mean rank obtained sequences of 2D thick slab SSFSE SENSE (14.50) better than the 2D thick slab SSFSE (0.00). Analysis of each anatomy showed significant differences in all organs except the gallbladder p = 0.059, p = left hepatic duct and the common bile duct 0.059 with p = 0.08.Conclusion: Parallel acquisition technique (SENSE) was well used because it has a faster acquisition time without decreasing image resolution.
