Abstract
PURPOSE: The purpose of this study was to examine the effects of using an ultrasound phantom (ECHOZY) and a volume navigation system (Vnavi) in abdominal ultrasonography training for young residents. METHODS: Nine third-year residents underwent abdominal ultrasonography training: controls, comprising five residents; and the ECHOZY + Vnavi group, comprising four residents. Residents were trained in abdominal ultrasound examinations using both educational videos and hands-on clinical training. The ECHOZY + Vnavi group also received training using an ultrasound phantom and volume navigation system. The time needed for abdominal ultrasound examination was calculated at 4 months (early), 8 months (middle), and 12 months (late) after starting training. The ability of each resident to visualize 20 abdominal structures on normal patients was also evaluated retrospectively. RESULTS: In the early period, the ECHOZY + Vnavi group needed significantly longer to complete examinations than controls (545 ± 125 s versus 392 ± 81 s, p < 0.01), but showed significantly better ability scores (17.5 ± 0.6 versus 13.4 ± 1.1, p < 0.05). Both these differences disappeared by the middle period (338 ± 107 s versus 259 ± 130 s and 17.8 ± 0.5 versus 16.0 ± 0.7). CONCLUSION: In spite of longer examination times, training residents in abdominal ultrasonography using an ultrasound phantom and volume navigation system may be useful in the early period.
