Evaluation of hepatic iron concentration heterogeneities using the MRI R2* mapping method.

Objective: To measure hepatic iron concentration (HIC) heterogeneities using a magnetic resonance R2* mapping method.

Patients And Methods: Ninety-four patients with suspected hepatic iron overload and 10 volunteers were included prospectively. A multi-echo R2* sequence with fat saturation and with three post-processing fitting methods (a single exponential decay model with or without truncation, SED and SEDt, and a constant offset model, COS) was compared to a signal intensity ratio method (SIR), considered as the reference.

Intra peritoneal abdominal fat area measured from computed tomography is an independent factor of severe acute pancreatitis.

Purpose: The purpose of this study was to search for a possible relationship between acute pancreatitis (AP) severity and visceral fat (VF) surface on contrast-enhanced computed tomography (CECT).

Material And Method: A total of 112 patients with AP who underwent CECT within 2 to 3 days after the beginning of AP were included. There were 68 mean and 44 women, with a mean age of 56.

Chart for renal tumor microwave ablation from human study.

Purpose: To define microwave ablation (MWA) charts according to time and power in human renal tumors and to compare them to the charts given by the HS AMICA manufacturer.

Materials And Methods: A total of 54 patients with 54 renal cancers who underwent MWA were included. There were 36 men and 18 women with a mean age of 72.
