ABSTRACT
Objective To evaluate the effectiveness and safety of MRI-navigation system EMT-100 in assisting the performance of precise percutaneous puncture biopsy.Methods With the help of MRI-navigation system EMT-100,percutaneous puncture biopsy of thoracic and abdominal lesions was performed in 42 patients.The puncture success rate was used as the main index to evaluate the effectiveness of MRI-navigation system EMT-100.The success rate of puncture biopsy,the total time used for procedure,the average number of puncturing,the average number of scanning,and the incidence of complications were recorded.Results In the 42 patients,the success rates with single and twice puncturing were 86% (36/42) and 14% (6/42) respectively.The success rate of puncture biopsy was 100%.The mean time used for locating puncture site was (11.5±5.5) min;the average number of puncturing was (1.4±0.5) times,and the average number of scanningwas(4.2±0.8) times.Among the 32 patients with pulmonary lesions,bloody sputum occurred in 2 patients (6.2%) and small amount pneumothorax in one patient (3.1%),and no serious complications occurred in other patients.Conclusion In performing percutaneous puncture biopsy of thoracic and abdominal lesions,the use of MRI-navigation system is safe.This technique has certain advantages,such as accurate positioning,high puncture success rate,wide range of application,radiationless,etc.It can help precisely obtain the lesion tissue and get pathological diagnosis.Therefore,it is really a valuable guiding technology.(J Intervent Radiol,2017,26:263-265)
