[Radiofrequency ablation for palliation of soft tissue tumor pain].

Purpose: To assess the efficacy of radiofrequency (RF) ablation for palliation of soft tissue tumor pain.

Materials And Methods: Retrospective study of 12 patients receiving palliative treatment for soft tissue tumors (5 primary tumors including 4 sarcomas and 1 PEComa and 7 metastatic tumors) with pain refractory to standard management. RF ablation was performed under CT or ultrasound guidance.

[Imaging of the intrahepatic biliary tree with thick slice MR cholangiography].

Purpose: To assess the value of single shot fast spin echo MR sequence (SS-FSE) in the evaluation of the normal and pathologic intrahepatic biliary tree.

Material And Methods: 418 consecutive patients (457 examinations) referred for clinical and/or biological suspicion of biliary obstruction underwent MR cholangiopancreatography (MRCP). All patients were imaged with a Signa 1.

[Computed tomography study of the sigmoid colon: discriminating diagnostic criteria and interobserver correlations].

Purpose: To assess the value of pericolonic findings at CT in the evaluation of the sigmoid colon.

Materials And Methods: A total of 210 CT examinations were retrospectively reviewed by 3 blinded radiologists. Data was analyzed to determine the interobserver correlation and the value of pericolonic and colonic wall findings in diagnosis of sigmoid colon pathology.
