臨床以往實施肩部軸位攝影檢查(Shoulder axillary view)皆利用電腦放射攝影板CR(Computed Radiography Film, C.R.Film)完成此攝影姿勢。但C.R.Film仍需經過C.R.讀片機做讀取分析，使得影像完成時間拉長許多。近年由於數位放射攝影(Digital Radiography, D.R.)的產生，讓影像呈現時間可大幅縮短，目前許多醫院大多以D.R.系統為主要攝影器材，但D.R.系統多為固定式攝影儀器，所以無法運用在常規之肩部軸位攝影。肩部關節不適的病患，在攝影時，對於姿勢擺位的正確性及配合度經常因肩部過於疼痛，無法長時間如同傳統常規攝影姿勢完成攝影，使得肩部軸位攝影檢查的影像誤差率提高。本研究收集30位因肩部關節不適而做肩部軸位攝影檢查的病患，其中男性18人，女性12人，年齡17歲至86歲，平均年齡51.10±19.48歲，收集同一病患曾經使用不同肩部軸位攝影檢查方法完成之影像分為對照組及實驗組。對照組為常規的肩部軸位攝影檢查，實驗組為利用直立式攝影裝置(wall stand)實施肩部軸位攝影檢查。研究所得到的影像品質，對照組病患的影像分數±SD為4.07±0.83;實驗組病患的影像分數±SD為4.40±0.56，兩組結果發現確實有明顯的差異性(pValue<0.05)。利用直立式攝影裝置實施肩部軸位攝影檢查，因成像系統的改變、降低擺位時間及減少影像讀取時間，可以大幅提昇肩部軸位攝影檢查的影像品質。

We used to use computed radiography system to perform shoulder axillary view clinically. But it takes time for C.R. reader to analysis image from C.R. film. However, digital radiography system can reduce much more time in image processing than C.R. system. D.R. system becomes the most widely used radiography system in these days. Due to the wall stand in D.R. system is fixed, we are unable to perform shoulder axillary view in the routine way. In the past, the routine shoulder axillary view requires patient remaining in the same position for a short time. But most of patients with shoulder injury are not capable of keeping still because of the pain in shoulder. Image quality of shoulder axillary view was often unsatisfied due to the inaccuracy of patient positioning and patient motion. This study collected 30 patients who had shoulder axillary view performed both by C.R. system and by wall stand in D.R. system. There were 18 male, 12 female, with age ranging from 17 to 86 year-old (mean age 51.10±19.48 years old). The images were divided into control group and experimental group. Images of shoulder axillary view in the control group were performed in the routine way with C.R. system, while images were performed with wall stand in D.R. system in experimental group. The image quality of our study shows evident difference between these two groups (p<0.05) with control group scores SD 4.07±0.83 and experimental group scores SD 4.40±0.56. We can reduce performing time and imaging processing time by using wall stand in D.R. system to improve image quality in shoulder axillary view.
