VARIASI SLICE COLLIMATION PADA PROTOKOL PEMERIKSAAN MSCT ABDOMEN TERHADAP NILAI DOSE LENGTH PRODUCT (DLP) DAN IMAGE NOISE : STUDI PADA WATER PHANTOM
- Bagikan:
Has conducted research in Radiology Instalation of K.R.M.T.
Wongsonegoro Hospital Semarang by using water phantom and MSCT Philips
Brilliance CT 16 Slice, in the MSCT abdominal protocols with variations slice
collimation 4 x 0.75 mm, 4 x 1.5 mm, 16 x 0,75 mm and 16 x 1.5 mm to see the
value of dose length product (DLP) and image noise. The purpose of this
research is to know differences in the value of dose length product (DLP) and
image noise in the variation of slice collimation, knowing the value of dose length
product (DLP) and image noise minimum value by displaying the image of the
abdominal MSCT optimal.
Quantitative research with an experimental approach. The data taken
from the results of scanning the water phantom using MSCT abdominal protocol
in 4 variations of slice collimation with each variation done 3 times scanning to
get the value of DLP and image noise. Then the value of DLP value is recorded
and measured results of MSCT image noise by utilizing the image region of
interest (ROI). Data analysis was performed using a different test. Statistical test
the value of DLP with descriptive test and image noise with ANOVA Repeated
methods as well as to see the lowest score of the DLP and image noise with the
mean rank.
The results showed that there was a differences in the value of DLP and
image noise in the variation of slice collimation, to the value of DLP lowest average
as 143,2 mGy.cm on a slice collimation 16 x 1.5 mm, for low noise image also on
the slice collimation of 16 x 1 , 5 mm. Image noise shows the p-value of 0.562,
which means p-value > 0.05 so that Ho refused and Ha is received, there are
differences in image noise on variations slice collimation, Results showed that the
mean rank of the lowest average for a value that is equal to 143.2 mGy.cm DLP
and to image noise is 3.637 HU on slice collimation of 16 x 1.5 mm slice
collimation so that variation is the right choice.
