Abstract

Background : Patients with HNP cases have a bigger chance to do a movement during MRI examination, and it causes poor MRI image. Quick time of MRI examination is needed to produce an optimal image. The technique of parallel imaging is a technique that can increase the speed of MRI data acquisition by passing through several lines of phase encoding in k-space. The GRAPPA technique is one of the methods used to reconstruct data on MRI parallel imaging techniques with better overall image quality. The technique of parallel imaging has a special parameter called acceleration factor. Acceleration factor (R-factor) will affect scan time. The purpose of this research is to know the difference of diagnostic image characteristic which is resulted in applying acceleration factor 2, 3 and 4 in parallel imaging of GRAPPA method and know the optimal acceleration factor to obtain MRI image of lumbar HNP case.Methods : This research type is quantitative research with descriptive approach. The study was conducted by MRI Siemens 3 T in RSUD Dr. Soedono Madiun. The data were 30 MRI images of lumbar sagittal of HNP cases on T2WI FSE with acceleration factor 2, 3 and 4 GRAPPA methodsResult : The results of this study indicate that there are differences in diagnostic image characteristics in the application of acceleration factor 2 and 4, 3 and 4 with VGA test. Acceleration factor value optimal with VGC test known is acceleration factor 2 and 3Conclusion : Based on the result there was differencediagnostic image characteristics of MRI Lumbar in sagital plane Fast Spin Echo (FSE)sequence with variation acceleration factor 2, 3 and 4 parallel imaging GRAPPA methode in case Herniated Nucleus Pulposus (HN0). Optimal value of variation acceleration factor value for MRI Lumbar examination of Heniated Nucleus Pulposus (HNP) is 2 dan 3.

Abstract

Tumor is basically an uncontrolled growth of cancerous cells in any part of the body, whereas a brain tumor is an uncontrolled growth of cancerous cells in the brain. Useing of MRI in diagnose tumors can be done with various sequences. Contrast medium is needed to evince tumor enhancement, as well as sequences that support to produce tumor in post contrast, one of which uses a conventional sequence T1WI SE. This sequences often lose information in providing images in cases of brain tumors and generally more time consuming. FSPGR BRAVO is a 3D volumetric acquisition that captures thin section images with near isotropic or isotropic spatial resolution. This sequence displays anatomy, especially brain parenchymal anatomy, in fine detail. The type of research in this mini research is a qualitative study with an observational approach which aims to find out sequences that can optimize post-MRI images in contrast to brain tumor cases with a short time and get the right diagnosis. Convensional sequence of MRI TIWI SE can’t detection of lessions in cerebral cortex. FSPGR BRAVO in producing images in 3D format in one-time retrieval of one particular piece and able to display anatomy especially the anatomy of the brain parenchyma in fine detail. FSPGR BRAVO can be used to assist cause to be uprise the diagnosis of MRI brain tumor by displaying the anatomy of the brain parenchyma in more fine detail, without the need for extended time.
