Keywords: Ultrasound, Real-time endosonography, Tissue elastography, Pancreas, Neuroendocrine tumors Introduction: the Smaller the Lesion, the Better the Prognosis Symptomatic pancreatic ductal adenocarcinoma (PDAC), which is the most commonly diagnosed solid malignant tumor of the pancreas, is generally diagnosed at a late stage with or ...

2025年1月23日 · pancreatic adenocarcinoma: On ultrasound examination, it often presents as an irregular hypoechoic mass with poorly-defined margins and possible invasion of nearby structures. pancreatic neuroendocrine tumors (PNETs): They may present on ultrasound as solid lesions with varying degrees of echogenicity

2022年8月12日 · Tumors in other parts of the pancreas won’t be visible with an abdominal ultrasound. But endoscope ultrasounds can better detect these tumors. Tumors will appear as masses on endoscopic images.

2023年7月26日 · CT scan: A CT scan uses data from X-rays to produce detailed images of the pancreas. A CT scan can also show if the cancer has spread to organs or lymph nodes near the pancreas. MRI: MRI scans use ...

2024年12月17日 · Focused ultrasound is a rapidly evolving, noninvasive therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with pancreatic tumors. This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the body without damaging surrounding normal tissue.

2019年8月16日 · Introduction Advances and widespread use of various diagnostic imaging modalities have dramatically improved our ability to visualize and diagnose pancreatic diseases. In particular, ultrasonography in pancreatic diseases plays an important role from screening to diagnosis as a simple and safe examination method. Methods The basic scanning method of transabdominal pancreatic ultrasonography ...

2016年4月1日 · Currently, ultrasound (US), computed tomography (CT) and Magnetic Resonance imaging (MRI) represent the mainstay in the evaluation of pancreatic solid and cystic tumors affecting pancreas in 80–85% and 10–15% of the cases respectively [1], [2].Integration of US, CT or MR imaging is essential for an accurate assessment of pancreatic parenchyma, ducts and adjacent soft tissues in order to ...

US is a noninvasive imaging modality that remains the first diagnostic test when pancreatic cancer is suspected. However, the sensitivity and specificity of transabdominal ultrasound for pancreatic cancer range from 75% to 89%, and 90% to 99%, respectively . The sub-optimal performance stems from several factors, including operator experience ...

2025年1月18日 · The objective is to develop and validate intratumoral and peritumoral ultrasomics models utilizing endoscopic ultrasonography (EUS) to predict pathological grading in pancreatic neuroendocrine tumors (PNETs). Eighty-one patients, including 51 with grade 1 PNETs and 30 with grade 2/3 PNETs, were included in this retrospective study after confirmation through pathological examination.

In patients with solid pancreatic lesions (SPLs), the differential diagnosis must be evaluated to determine whether radical surgery, pancreatic parenchyma-saving strategies, or follow-up is indicated. ... ultrasonography and elastography facilitate the further characteriza … Modern ultrasound imaging of pancreatic tumors Ultrasonography. 2020 ...
