Latar belakang. Ultrasonografi doppler digunakan sebagai tambahan pada pemeriksaan USG abdomen untuk membantu membedakan steatotic liver dan organ normal, karena sangat terlihat perbedaan flow patterns antara pasien fatty liver dengan orang normal. Tujuan penelitian. Mengetahui kesesuaian fatty liver dari pemeriksaan CT scan abdomen non kontras dengan USG doppler vena porta. Bahan dan Cara. Metode penelitian ini menggunakan desain penelitian uji kesesuaian cross-sectional non eksperimental dengan pengambilan sampel data CT-scan non-kontras dan data USG Doppler Vena Porta yang dilakukan di Instalasi Radiologi RSUP Dr.Sardjito. Subyek penelitian ini adalah pasien yang telah dilakukan pemeriksaan CT scan abdomen non kontras dan didapatkan hasil fatty liver. Besar sampel penelitian tiap kelompok kategorik minimal 19 sampel. Subyek penelitian diamati oleh seorang dokter spesialis radiologi dengan pengalaman lebih dari lima tahun menginterpretasi hasil CT Scan dan USG doppler vena porta. Dari hasil interpretasi dokter spesialis radiologi dilakukan uji kesesuaian fatty liver dan uji kesesuaian fatty liver CT-scan non-kontras dengan USG doppler vena porta menggunakan analisis statistik Mc Nemars. Hasil. Pada kelompok normal tidak dijumpai hasil USG doppler vena porta dengan velositas menurun 0 (%). Sebanyak 17 (44.7%) subyek pada kelompok fatty liver memiliki velositas vena porta yang menurun dan 2 (5.3%) dengan hasil velositas vena porta normal. Dari analisis didapatkan nilai p = 0,000. Oleh karena p < 0,05 artinya ada hubungan antara velositas porta vena dengan hasil ct scan. Kesimpulan. Terdapat terdapat kesesuaian interpretasi pada pemeriksaan USG doppler vena porta dan CT-Scan non kontras dalam penentuan fatty liver.

Background. Doppler ultrasonography is used as an adjunct to abdominal ultrasound examination to help differentiate steatotic liver and normal organs, as there is a noticeable difference in flow patterns between fatty liver patients and normal people. Purpose. Knowing the suitability of fatty liver from non-contrast abdominal CT scan examination with portal vein doppler ultrasound. Methods and Material. The research method used non-experimental crosssectional suitability test, with non-contrast CT-scan and portal vein doppler ultrasound data sampling at Instalasi Radiologi RSUP Dr.Sardjito. The subjects of this study were patients who had performed non-contrast abdominal CT scan and obtained fatty liver results. The sample size of each group of at least 19 samples. The subjects of the study were observed by a radiologist with more than five years of experience in interpreting CT Scan and portal vein doppler ultrasound. From the interpretation of radiologist, a fatty liver suitability test was performed and a non-contrast fatty liver CT-suitability test with portal vein doppler ultrasound using statistical analysis of Mc Nemar's. Results. In the normal group there was no portal vein doppler ultrasound result with decreased velocity 0 (%). A total of 17 (44.7%) subjects in the fatty liver group had decreased portal vein velocity and 2 (5.3%) with normal portal vein velocity. From the analysis obtained p value = 0.000. Therefore p <0.05 means there is a link between the portal vein velocity with the results of a CT scan. Conclusions. There is an interpretive suitability on the portal vein doppler examination and non-contrast CT scan in the determination of fatty liver.
