Abstract

Background : Examination of Thorax CT Scan in RSUD Dr.Moewardi is always conducted using bolus triggering technique, where delay of bolus triggering activation done to vary value between 5 - 10 second after contrast media administration using automatic injector with the reason to lessen radiation dose. Purpose of this research is to know influence of  bolus triggering activation delay to radiation dose as well as  to find out  maximal delay value of  bolus triggering activation delay which can be conducted at CT Scan Thorax examination.Methods : This research is experimental method. Data were collected from the observations and the direct examinations on the monitor screen using the CTDIvol dose calculation software. This research is carried out by recording the changes radiation dose value on CTDIvol by changing the value of  bolus triggering activation delay from 0, 2, 4,  6, 8, 10, 12 and 14 second. Data were analyzed using regression test.Results : The result shows that correlation between bolus triggering activation delay towards radiation dose with r = 0,970,  p value < 0,001 and R2 = 0,940. The meaning 94% radiation dose influenced by bolus triggering activation. Delay with regresi equation, Y  = 308,252 - 18,821 DT, showing each every increase of delay bolus triggering activation delay equal to 1 second  will influence to descend dose radiasi equal to 18,821 mGy.Conclusion : Maximum delay to activated bolus triggering is 17 second.

Abstract

Background : Field of view (FOV) is one of paramaters in MRI that is possibly adjusted by a radiographer. Many various adjusment of FOV that are using for lumbar MR Imaging. This study is to determine the effect of variations in the value of FOV to the image quality and anatomical information.Methods : This is a quasy experimental research. The study was conducted with 1.5 Tesla MRI. Data were collected from three volunteers with 5 variations of FOV (17cm, 22cm, 27cm, 32cm and 37cm) which is totally 15 images acquired.  Images were evaluated according to the objective evaluation of SNR and CNR  by a software in the MRI machine. Quntitative measurements of SNR were conducted on corpus vertebrae, discus intervertebralis, medulla spinalis, cerebrospinal fluid (CSF) and ligamentum flavum respectively. While CNR measurements were on CSF-corpus vertebra, CSF-discus intervertebralis, CSF-medulla spinalis, medulla spinalis-corpus vertebra, medulla spinalis-discus intervertebralis and corpus vertebra-discus intervertebralis. For conspicuity, overall image contrast and artifacts were evaluated qualitatively by three radiologists scoring on the paper sheet based on the image of corpus vertebrae, discus intervertebralis, medulla spinalis, cerebrospinal fluid, ligamentum flavum. Quantitative data of SNR and CNR value were analyzed using Linier Regression and Correlation Spearman test. While radiologists scoring were analyzed using Friedman test and cross tabulation.Results : The results showed that FOV variations affect the image qualities of T2WI FSE sagital lumbar MR Imaging. FOV variations are significantly corelate to the SNR of corpus vertebra, discus intervertebralis, medulla spinalis, CSF and ligamentum flavum. FOV variations are also significantly correlate to the CNR value  of CSF-corpus vertebra, CSF-discus intervertebralis, CSF-medulla spinalis, medulla spinalis-corpus vertebra and medulla spinalis-discus intervertebralis (p values 0,05) with positive correlation.  But there is  no correlation between FOV variations  and CNR  at the corpus vertebra-discus intervertebralis (p values = 0,109).Conclusion : Based on these results indicate that overall image and artifacts are relatively similar for all value of FOV variations.  Optimal values of FOV for T2WI FSE sagittal lumbar MR Imaging is a FOV of  27 cm.
