A comparison of smooth and sharp kernel CT reconstructions in the detection of unilateral sacral fractures.

Objective: The goal of this study is to determine whether smooth kernel reconstructions are more sensitive than sharp kernel ones for the detection of sacral stress fractures (SF) using MRI as the reference standard.

Materials And Methods: This retrospective study included 100 subjects in whom CT and MR of the pelvis were performed for a clinical suspicion of SF from January 2014 to May 2020 in our institution. MR was used as the reference standard for the presence of SF.

Artificial ascites using the guidewire technique during microwave ablation in the liver dome: technique and analysis of fluid repartition.

Purpose: To describe the guidewire technique to perform hydrodistension and create artificial ascites during liver microwave ablation (MWA) of tumors located in the hepatic dome and evaluate the effectiveness of repartition of peritoneal fluid along segments VII and VIII with this technique.

Materials And Methods: A retrospective review of all 18 consecutive patients who benefited from MWA combined with hydrodistension causing artificial ascites performed with the guidewire technique was conducted. The technique involves inserting a 20G spinal needle in the liver parenchyma and catheterizing the peritoneum with a 0.
