Abstract

Background: Magnetic Resonance Imaging (MRI) is a diagnostic imaging modality that can generate slices anatomy body multiplanar by contrast in a very good resolution. The results of the  of an MRI description is more accurate for diagnosing Carcinoma of the nasopharynx. On examination of of the neck MRI  with the case of carcinoma, after infusion of contrast Moeller and Reif (2003) suggested to use T1 TSE Coronal and axial sequence  and using the 4 mm slice thickness , but in Radiology instalation of  Ken Saras Hospital using  T1 and T1 TSE TSE Fat Saturation Coronal, sagittal and axial sequence as well as using slice thickness 2 mm in axial slices. The purpose of this research is to know the procedure of examination of of the neck MRI  in the case of Carcinoma of the nasopharynx, justifying  T1 Fat Saturation sequence after infusion media kontaras and reasons of  wearing slice thickness 2 mm in axial slices.Methods: This type of research is qualitative research with case studies approach. Data retrieval is done by  observation, documentation, interviews with two specialists in radiology, 2 radiografer and 1 doctor who send the patient.  The data obtained  analized  by using the table  categorisation and coding.Result: The results of the research showed that MRI examination procedure of the neck in the case of Carcinoma of nasopharynx in Radiology Installation of  Ken Saras hospital using  T1 TSE multi planar (coronal, sagittal and axial), T2 TSE multi planar and T2 TSE Fat Saturation multi planar sequences before infusion of contrast media,  T1 and T1 TSE TSE Fat Saturation multi planar sequences after infusion contrast and using the slice thickness 2 mm in axial slices. Addition sequence T1 TSE Fat Saturation after infusion of contrast aimed to clarify the limits of the tumor with surrounding tissue and image of  Lymphadenopathy.Conclusion: While using 2 mm slice thickness  in axial slices aims to show the abnormalities or nodules-small nodules on the nasopharynx and to see the expansion Stadium in the  surrounding area of the nasopharynx.

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

Background : MRCP is an examination used to evaluate the system billiary, pancreas and gall bladder with channel because of the possible presence of stones, tumors and other diseases. To diagnose the MRCP examination,one sequence in use is T2 weighted Turbo Field Echo Balance (T2W BTFE) which in its parameters No Sensitivity Enchoding (SENSE). The purpose of this study was to determine the Information analysis Anatomical differences with variation of Sensitivity Encoding (SENSE) on T2-weighted sequences BTFE the MRCP examination, And to investigate value Sensitivity Encoding (SENSE) optimal T2-weighted sequences BTFE the MRCP examination.Methods : The method of this research is experimental with approach quasi-experimental design with control. This research is done in Siloam Hospital Surabaya. MRCP image data in the form of axial 40 of the 10 patients with 4 variation of Sensitivity Encoding (SENSE), which are 1.4, 1.6, 1.8, and 2. Assessment of information image data done by 3 respondents. Analysing process done with Friedman test.Results : The results showed that there MRCP image information differences with variation in sensitivity encoding (SENSE) on T2-weighted sequences BTFE with a significance level of p value 0.001. Differences in image information occurs in liver, Gall Blader, Pancreas and CBD (Common Bile Duct). The use value Sensitivity Encoding (SENSE) on T2-weighted sequences for optimal BTFE MRCP is a 1.8 with a mean rank 3.85.Conclusion : The optimal use value Sensitivity Encoding (SENSE) on T2-weighted sequences for optimal BTFE MRCP is a 1.8.

Abstract

Backgroud: blurring artifact is an issue in axial cervical MRI using T2 Turbo Spin Echo (TSE) weighted Cartesian. T2W TSE BLADE is potential to substitute its shortcomings. This study aims to analyze the image quality and artifacts between T2W TSE Cartesian and T2W TSE BLADE on axial cervical MRI examination and to determine the better sequence in producing image quality.Methods: this is a quantitative research with descriptive approach. 7 volunteers were scanned for cervical axial examination with T2W TSE, T2W TSE Cartesian and T2W TSE Blade. Images were processed in MathlabTM. SNR of intervertebral disc, spinal cord and CSF were measured using ROI. Image resolution were find out from pixel spacing in DICOM info. Blurring artifact were analyzed by comparing the signal of blurred area to the background noise. Data were analyzed using descriptive statistics.Results: SNR of T2W TSE Cartesian and T2W TSE BLADE were 22,144 and 17,532 (intervertebral disc), 20,952 and 16,786 (spinal cord), and 16,717 and 12,883 (CSF) respectively. Image resolution (mean) were 0,391 pixel/mm (T2W TSE Cartesian) and 0,625 (T2W TSE BLADE). Blurring artifact were 8,161 (T2W TSE Cartesian) and 6,826 (T2W TSE Blade).Conclusion: T2W TSE Cartesian was superior in pixel intensity and SNR, while the blade technique was superior in terms of spatial resolution and artifacts reduction. Thus, it is recommended to be applied in clinical field if the SNR or image detail is the priority.
