BACKGROUND. The 2019 WHO classification of digestive system tumors separates neuroendocrine neoplasms (NENs) into (NETs) and carcinomas (NECs), which are considered to represent pathologically distinct entities warranting different management approaches. Dual-layer spectral-detector CT (DLCT) may aid their differentiation through specific material decomposition. OBJECTIVE. purpose this study was assess the utility quantitative metrics derived from DLCT for pancreatic NET NEC. METHODS. This...
To explore the optimal energy level of dual-layer spectral detector computed tomography (DLCT) images pancreatic neuroendocrine neoplasms (pNENs) and investigate value in their detection.This retrospective analysis included 134 pNEN patients with 136 lesions; they underwent contrast-enhanced DLCT scanning histopathological confirmation pNENs. Virtual monoenergetic (VMI) 40-100 keV, iodine concentration map (IC map), Z-effective atomic number (Zeff conventional were analysed. The was obtained...
Patients with chronic pancreatitis often have irreversible pancreatic insufficiency before a clinical diagnosis. Pancreatic cancer is fatal malignant tumor in the advanced stages. having high risk of diseases must be screened early to obtain better outcomes using new imaging modalities. Therefore, this study aimed investigate reproducibility tomoelastography measurements for assessing stiffness and fluidity variance among healthy volunteers.Forty-seven volunteers were prospectively enrolled...
<title>Abstract</title> Background The mechanical properties of pancreatic diseases provide new insight for diagnosis and differentiation. Tomoelastography, a multifrequency MR elastography technique, provides high-resolution maps shear wave speed (<italic>c</italic> in m/s) phase angle (<italic>φ</italic> rad) evaluating stiffness fluidity. We explore the diagnostic performances fluidity quantified using tomoelastography differentiating between non-functional neuroendocrine neoplasms...
This prospective study enrolled patients with pathologically confirmed solid pseudopapillary tumors (SPNs) and pancreatic neuroendocrine (pNENs) who underwent preoperative tomoelastography examinations at our hospital. Sixty-four were included (18 SPNs; 46 pNENs). SPNs showed significantly lower stiffness (P<0.001) fluidity (P=0.001) than pNENs. Both allowed distinguishing from AUCs 0.899 for stiffness, 0.760 fluidity. Tomoelastography is a novel multi-frequency MRE technique that can...
