Possibilities of Multiparametric Ultrasound Navigation in Biopsies of Neuroendocrine Neoplasia of the Pancreas.

Purpose : Improved biopsy results of neuroendocrine neoplasia of the pancreas and neuroendocrine neoplasia of the gastrointestinal tract of other locations under ultrasound navigation. Materials and methods : The study included 56 CT scans with intravenous contrast and clinical and laboratory methods of examining neuroendocrine neoplasia of the pancreas. The results of biopsies of neuroendocrine neoplasia of the pancreas were analyzed under ultrasound navigation in the usual B-mode and in the B-mode with complex methods for determining the elasticity of pancreatic tumors (elastometry and elastography), doppler imaging and improved visualization in B-mode. Conclusion : Additional ultrasound techniques allow us to provide qualitative and quantitative criteria for the tumor structure, which technically allows us to obtain a high-quality biopsy and avoid unnecessary biopsies.
