Latar belakang.Ultrasonografi doppler digunakan sebagai tambahan pada pemeriksaan USG abdomen untuk membantu membedakan fatty 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 RI arteri hepatica 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 RI arteri hepatika 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 dan telah melakukan pemeriksaan USG Doppler arteri hepatika. Besar sampel penelitian tiap kelompok kategorik minimal 19 sampel. Subyek penelitian diamati oleh seorang dokter spesialis radiologi dengan pengalaman lebih dari sepuluh tahun menginterpretasi hasil CT Scan. Dari hasil interpretasi dokter spesialis radiologi dilakukan uji kesesuaian fatty liver dan uji kesesuaian fatty liver CT-scan non-kontras dengan USG Doppler arteri hepatika menggunakan analisis statistik Chi Square. Hasil. Pada kelompok normal didapatkan sebanyak 9 (47,4%) didapatkan hasil USG Doppler RI arteri hepatika yang menurun, dan sebanyak 10 (52,6%) didapatkan hasil RI arteri hepatika normal. Sebanyak 10 (52,6%) subyek pada kelompok fatty liver memiliki RI arteri hepatika yang menurun dan 9 (47,4%) dengan hasil RI arteri hepatika normal. Dari analisis didapatkan nilai p = 0,746. Oleh karena p > 0,05 berarti perbedaan nilai RI arteri hepatika dengan interpretasi CT scan pada kasus fatty liver tidak signifikan, atau dengan kata lain terdapat kesesuaian antara nilai RI Kesimpulan. Terdapat kesesuaian interpretasi pada pemeriksaan USG Doppler RI arteri hepatika dan CT-Scan non kontras dalam penentuan fatty liver.

Background: Doppler ultrasound is used as a supplementary to abdominal ultrasound examination to aid in distinguishing between fatty liver and normal organs, because of spectral waveforms were obviously different between fatty liver patients and normal people. The purpose of this study was to determine the concordance of fatty liver interpretation between doppler ultrasonographic of hepatic artery and non-enhancement ct-scan. Material and methods:The study design was a non-experimental cross-sectional retrospective observational analytic study conducted at the Radiology Installation of Dr. Sardjito Hospital. The subjects of this study were patients who had examined non-enhanced abdominal CT scan and obtained fatty liver results and had examined Doppler ultrasonographic of the hepatic artery. Sampling method was non-random consecutive sampling. The sample size of each categorical group was 19 samples. The subjects of the study were observed by a radiologist with more than 10 years of experience interpreting CT scan and then compared to the findings of the Doppler ultrasonographic of hepatic artery. The data was analized by using Chi Square test. Results: In the normal group, there was decreasing of the Doppler resistant index (RI) of the hepatic artery in the amount of 9 (47,4%), and 10 (52,6%) were normal. A total of 10 (52.6%) subjects in the fatty liver group had a decreased of the Doppler resistant index (RI) of the hepatic artery and 9 (47.4%) were normal. It was obtained p value = 0.746 (p value > 0,05). It means there was no significant difference between the Doppler resistant index (RI) of the hepatic artery with interpretation of non-enhanced CT scan in patient with fatty liver, or in other words there was concordance between Doppler resistant index (RI) of the hepatic artery with interpretation of non-enhanced CT scan in the diagnosis fatty liver. Conclusion:There was concordance between Doppler resistant index (RI) of the hepatic artery with interpretation of non-enhanced CT scan in the diagnosis of fatty liver.
