Latar Belakang : Salah satu penunjang diagnosis osteoarthritis adalah foto rontgen. Tetapi dengan keadaan geografis Indonesia dan jumlah spesialis radiologi yang tidak memadai, maka muncul gagasan penggunaan teleradiologi. Teleradiologi ini harus didukung oleh hasil pencitraan yang baik sehingga gambar yang dihasilkan tidak menimbulkan bias penafsiran. Tujuan : Mengetahui perbedaan kualitas gambar dan kesesuaian diagnosis antara film hard copy dengan soft copy hasil digitizer dan soft copy hasil kamera saku pada foto Osteoarthritis Genu. Metode dan Material : Penelitian observational pada 25 foto polos osteoarthritis genu. Data digital work station di print menggunakan laser printer menghasilkan hard copy yang kemudian didigitalisasi menggunakan digitizer dan kamera saku. Kualitas gambar hard copy dibandingkan dengan kualitas gambar soft copy hasil digitalisasi menggunakan digitizer dan kamera saku. Hasil : Kelompok kualitas citra hard copy memiliki rerata 7.76, standar deviasi 1.26, nilai minimum 6.00, nilai maximum 9.00 dengan uji Shapiro-Wilk 0.000. Kelompok kualitas gambar digitizer memiliki rerata 7.72, standar deviasi 1.27, nilai minimum 5.00, nilai maximum 9.00 dengan uji Shapiro-Wilk 0.002. Kelompok kualitas gambar kamera saku memiliki rerata 6.68, standar deviasi 1.67, nilai minimum 4.00, nilai maximum 9.00 dengan uji Shapiro-Wilk 0.026. Kelompok kesesuaian diagnosis hard copy memiliki rerata 4.76, standar deviasi 1.26, nilai minimum 3.00, nilai maximum 6.00 dengan uji Shapiro-Wilk 0.000. Kelompok kesesuaian diagnosis digitizer memiliki rerata 4.72, standar deviasi 1.27, nilai minimum 2.00, nilai maximum 6.00 dengan uji Shapiro-Wilk 0.002. Kelompom kesesuaian diagnosis kamera saku memiliki rerata 4.72, standar deviasi 1.27, nilai minimum 3.00, nilai maximum 6.00 dengan uji Shapiro-Wilk 0.000. Kesimpulan : Tidak terdapat perbedaan kualitas citra yang bermakna secara statistik antara hard copy dengan soft copy hasil digitalisasi dengan digitizer pada foto polos osteoarthritis genu. Terdapat perbedaan kualitas citra yang bermakna secara statistik antara hard copy dengan soft copy hasil digitalisasi dengan kamera saku pada foto polos osteoarthritis genu yaitu hard copy mempunyai kualitas citra yang lebih baik. Tidak terdapat perbedaan kesesuaian diagnosis yang bermakna secara statistik antara hard copy dengan soft copy hasil digitalisasi dengan digitizer maupun kamera saku pada foto polos osteoarthritis genu.

Background : One of the supporting diagnosis of osteoarthritis is the x-rays. But with Indonesia's geographical situation and the number of radiology specialists inadequate, it appears the idea of the use of teleradiology. Teleradiology must be supported by good imaging results so that the resulting image does not lead to biased interpretation. Objective : To determine differences in image quality and appropriateness of diagnosis between films with hard copy and soft copy of the digitizer soft copy of the pocket camera on the photo Genu Osteoarthritis. Methods and Materials : an observational study on 25 osteoarthritis genu plain. Digital data in the print work station using a laser printer to produce a hard copy which is then digitized using a digitizer and a pocket camera. The image quality compared to the hard copy soft copy image quality results using the digitizer digitizing and pocket cameras. Results : The group has a hard copy image quality mean 7.76, standard deviation 1:26, 6:00 minimum value, maximum value of 9:00 with the Shapiro - Wilk test of 0.000. Image quality digitizer group had a mean 7.72, standard deviation 1:27, 5:00 minimum value, maximum value of 9:00 with the Shapiro - Wilk test of 0.002. Group picture quality pocket camera has a mean of 6.68, standard deviation 1.67, minimum value of 4:00, 9:00 with the maximum value of the Shapiro - Wilk test of 0.026. Appropriateness of the diagnosis group had a mean hard copy 4.76, standard deviation 1:26, 3:00 minimum value, maximum value of 6:00 with the Shapiro - Wilk test of 0.000. Appropriateness of the diagnosis group had a mean 4.72 digitizer, standard deviation 1:27, 2:00 minimum value, maximum value of 6:00 with the Shapiro - Wilk test of 0.002. Kelompom suitability pocket camera diagnosis had a mean 4.72, standard deviation 1:27, 3:00 minimum value, maximum value of 6:00 with the Shapiro - Wilk test of 0.000. Conclusions : There was no difference in image quality between the statistically significant with a hard copy to soft copy digitizer digitizing results on plain radiography of osteoarthritis genu. There is a difference in image quality between the statistically significant with a hard copy to soft copy of digitizing results on plain pocket camera osteoarthritis genu ie hard copy has better image quality. There were no differences suitability diagnosis was statistically significant between the hard copy to soft copy of the digitizer or digitizing with a pocket camera in plain radiography of osteoarthritis genu.
