A Clinical Value of 3D Modeling in the Optimization of Paracentetic Approach to Retroperitoneal Masses Assisted by Ultrasonography

OBJECTIVE: To investigate the clinical value of 3D and 4D ultrasound monitoring for aspiration biopsy in the diagnosis of pancreatic, adrenal and lymph node masses. METHODS: 60 patients with retroperitoneal masses underwent fine needle aspiration biopsy. A total of 60 fineneedle aspiration biopsies were 3D US correlated after typical 'free-hand' US needle guidance. All cases were examined with a linear 3D US volume scanner (5–13 MHz, Voluson 530D, MedisonKretztechnik, Zipf, Austria). After coreneedle stroke or localization of fine needle, a 3D US data volume set was acquired and a multiplanar analysis performed. RESULTS: In all cases aspiration biopsy was successfully made without any serious complication. Final histology confirmed the results of the aspiration biopsy specimen. CONCLUSION: 3D US combined with 3D targeting technique is a reliable and objective tool demonstrating exact spatial positioning of core and fine needle during biopsy procedure. Authors suggest the criteria of choice of the optimal needle trajectory for the fine needle approach to the retroperitoneal masses.
