Volumetric Enhancing Tumor Burden at CT to Predict Survival Outcomes in Patients with Neuroendocrine Liver Metastases after Intra-arterial Treatment.

Purpose To investigate whether liver enhancing tumor burden (LETB) assessed at contrast-enhanced CT indicates early response and helps predict survival outcomes in patients with multifocal neuroendocrine liver metastases (NELM) after intra-arterial treatment. Materials and Methods This retrospective study included patients with NELM who underwent intra-arterial treatment with transarterial embolization (TAE) or chemoembolization (TACE) between April 2006 and December 2018. Tumor response in treated NELM was evaluated by using the Response Evaluation Criteria in Solid Tumors (RECIST) and modified RECIST (mRECIST).

[Imaging of chronic pancreatitis].

Imaging of chronic pancreatitis. Chronic pancreatitis is a combination of imaging pattern: duct abnormalities, with irregularity, enlargement alternating with stenosis, of main pancreatic duct (beading) and enlargement of branch duct (more than 3 thin branch ducts visible); intra ductal or parenchymal calcifications; parenchymal atrophy, global or focal. When CT is typical, no more imaging is needed.

Preoperative CT scan helps to predict the occurrence of severe pancreatic fistula after pancreaticoduodenectomy.

Objective: To assess the influence of body fat distribution, estimated by a preoperative computed tomographic (CT) scan, on pancreatic fistula (PF) risk after pancreaticoduodenectomy (PD).

Background: Pancreatic fatty infiltration is a predictive factor of PF, but accurate preoperative assessment is challenging. We hypothesized that it could be associated with an increased visceral obesity and could be assessed preoperatively.
