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

The Research of this study was to determine the relationship of slice thickness to Maximum Intensity Projection (MIP) reconstructive image information and determine the exact slice thickness to the MIP processing of MSCT examination of Abdominal Angiography. Type of research is quantitative with an experimental approach, using a sample of 6 patients. Each patient performed a MIP reconstruction of the abdominal artery that is truncus coeliacs artery, gastric artery, hepatic artery, splenic artery, superior mesenteric artery, inferior mesenteric artery, renal artery, and communis iliac artery with variations in slice thickness of 5, 10, 15, 20 and 25 mm. Correlation test results produce a P-value= 0.001 smaller than α= 0.05 so that Ho is rejected and Ha is accepted, which means there is a relationship between slice thickness with image information on the MIP processing of abdominal arteries. Correlation coefficient value obtained is 0.593 so that the relationship obtained is moderate. The negative relationship is that the smaller the slice thickness, the diagnostic information on the abdominal artery is clearer, the greater the slice thickness, the diagnostic information generated is increasingly unclear. MIP reconstruction of the abdominal artery can produce clear image information on 5 mm and 10 mm.

Abstract

Pengujian kolimator merupakan factor yang cukup penting dan menjadi salah satu dalam parameter pengujian pesawat sinar X utnuk mendapatkan perijinan dari bapeten. Akan tetapi dilapangan, hal ini menjadi sedikit terabaikan karena tidak berhubungan secara langsung dengan produksi sinar-X, oleh karena itu dilakukan kegiatan pengabdian masyarakat dalam bentuk pelatihan dan pendampingan pengujian sistem kolimator. Kegiatan ini bertujuan Untuk memberikan pelatihan bagi radiografer dalam memastikan kinerja sistem kolimator pada pesawat sinar X, dalam rangka upaya keselamatan radiasi pada unit pelayanan radiologi Rumah Sakit di Kota Semarang. Sasaran kegiatan ini adalah radiografer di Instalasi Radiologi pada Rumah Sakit di Kota Semarang. Kegiatan dikemas dalam bentuk kegiatan pelatihan dan pendampingan yang memungkinkan para peserta mempraktekan secara langsung, sehingga materi pengabmas diharapkan dapat lebih dipahami dan diterapkan di masing-masing pesawat radiologi oleh para peserta. Materi pelatihan meliputi penjelasan mengenai quality assurance dari pesawat sinar-X, khususnya system kolimator dan dilanjutkan dengan praktek pengujian secara langsung. Hasil akhir pengabmas adalah berupa buku petunjuk pengujian. Sebagai bentuk tindak lanjut dilakukan pendampingan bagi peserta untuk melakukan di tempat masing-masingsebagai bentuk dari upaya keselamatan radiasi.
