Philips EBW工作站操作示範:困難心臟血管疾病


講者:蔡依橙 醫師

        多切面電腦斷層的資料量大,用過去的工作流程,無法將儀器的威力最大化。許多疑難雜症,只有在工作站旁才能找到答案。例如:評估主動脈瓣的開合狀況,需要親手找到最佳平面。尋找冠狀動脈慢性完全阻塞的側枝循環,需要自訂最佳成像方式反覆搜索。

        我們將現場示範三個由Philips Brilliance 40, 64, iCT掃描的案例,展示其優異的原始影像品質,並分享工作站判讀流程。


Case 1: Kawasaki disease

M/18Y, Kawasaki disease during infancy, for follow up
Scanner: Philips Brilliance 40
Diagnosis: Kawasaki disease with calcification, thrombus over LCA & CTO over RCA
Best Phase: 70%
Interpretation points:
1. LCA calcification and thrombus
2. RCA CTO and vasa vasorum collateral
3. Wall motion
Case 2: ALCAPA

F/6Y, Echo: Kawasaki disease and Swiss cheese VSD, for MDCT
Scanner: Philips Brilliance iCT
Diagnosis: ALCAPA (Anomalous left coronary artery from pulmonary artery)
Best Phase: 50%
Interpretation points:
1. Diagnosing ALCAPA
2. Understanding the hemodynamic and effect to myocardium
3. 4D motion
Case 3: Neonatal cardiac CT 

F/2day, Echo: R/O COA, for MDCT
Scanner: Philips Brilliance 64 (132bpm)
Diagnosis: Coarctation syndrome with coarctation, SVAS, VSD and ASD (not clear)
Best phase: 40%, coronary seen in many phases
Interpretation points:
1. Coarctation, SVAS, VSD and ASD
2. Large PDA
3. Coronary arteries
