Focal Nodular Hyperplasia After Treatment With Oxaliplatin: A Multiinstitutional Series of Cases Diagnosed at MRI.

Objective: Benign hepatic lesions may occur after chemotherapy treatment and may mimic metastases at imaging. We describe focal nodular hyperplasia (FNH) lesions diagnosed at MRI that occurred de novo after treatment with oxaliplatin.

Materials And Methods: This is a multiinstitutional case series.

Umbilical venous catheters placement evaluation on frontal radiogram: application of a simplified flow-chart for radiology residents.

Background: Umbilical Venous Catheter (UVC) are commonly used in neonatal period; they can be not correctly positioned and could be associated with complications. The purpose of this article is to suggest a flow-chart to evaluate the placement of UVC, testing it in young radiologists-in-training.

Method: We developed a simple flow-chart to asses, steps by step, UVC placement considering its course and tip location (ideally placed in the atriocaval junction).
