Abstract

The anteroposterior (AP) projection of the Ossa Pedis examination technique in some hospitals typically uses a perpendicular 0° beam angle, while the theoretical approach uses a 10° cephalad beam angle. This study aims to compare variations in 0° and 10° cephalad beam angles and provide more informative anatomical information. The study used a quantitative experimental approach in the Radiology Laboratory of the Faculty of Vocational Studies, Baiturrahmah University, from June to August 2025. The study involved a population of 79 individuals and a sample size of 3 individuals. Data were collected through radiographic images and then assessed by 5 radiology specialists and 25 radiographers using a questionnaire with a 5-item Likert scale. Question 1 depicts the anatomy of the tarsal bones, Question 2 depicts the space between the metatarsals, Question 3 depicts the lower part of the metatarsals, Question 4 depicts the joint space between the medial cuneiform and the intermedial cuneiform, Question 5 depicts the joint space between the interphalangeal joint, metatarsophalangeal joint, and tarsometatarsal joint. Data processing using SPSS with the Wilcoxon test is presented in figures and tables. Based on the results, the 0° angle produced a lower average value of 17.64, while the 10° cephalad angle produced a more optimal image with a higher average value of 22.72. This image has the advantage of a more open joint space, a more defined metatarsal base, and clearer alignment of the foot bones due to reduced superposition. With a p-value of <0.005, it can be concluded that there are differences in the anatomical images in the anteroposterior (AP) projection pedis examination at 0° and 10° cephalad angles.

Abstract

Pemeriksaan vertebrae lumbosacral proyeksi lateral memerlukan posisi pasien yang tepat agar struktur anatomi dapat tervisualisasi secara optimal. Penggunaan wedge support berperan membantu penyelarasan tulang belakang sehingga mempengaruhi kualitas gambaran space intervertebralis, foramen intervertebralis, dan margin posterior vertebrae. Penelitian ini bertujuan untuk mengetahui perbedaan kualitas anatomi radiograf vertebrae lumbosacral proyeksi lateral pada penggunaan wedge support 5 cm, 8 cm, dan tanpa wedge support. Penelitian ini merupakan penelitian kuantitatif dengan desain eksperimen yang dilaksanakan pada bulan Oktober 2025 di Laboratorium Radiologi Universitas Baiturrahmah. Sampel penelitian berupa radiograf vertebrae lumbosacral proyeksi lateral dalam tiga kondisi pemeriksaan, yaitu menggunakan wedge support 5 cm, wedge support 8 cm, dan tanpa wedge support. Penilaian kualitas anatomi dilakukan oleh 30 responden yang terdiri dari 5 dokter spesialis radiologi dan 25 radiografer menggunakan kuesioner skala Likert. Data dianalisis menggunakan uji statistik Friedman. Hasil penelitian menunjukkan nilai rata-rata kualitas anatomi tertinggi pada penggunaan wedge support 5 cm sebesar 14,73, diikuti wedge support 8 cm sebesar 14,11, dan tanpa wedge support sebesar 13,16. Penggunaan wedge support 5 cm menghasilkan keterbukaan space intervertebralis dan foramen intervertebralis yang lebih merata serta superposisi margin posterior yang optimal. Uji Friedman menunjukkan perbedaan yang signifikan dengan p-value 0,001 (p < 0,05). Dapat disimpulkan bahwa penggunaan wedge support 5 cm merupakan pilihan paling optimal dalam menghasilkan gambaran anatomi vertebrae lumbosacral proyeksi lateral yang informatif.
