Accuracy of core needle biopsy for the diagnosis of osteosarcoma: A retrospective analysis of 73 patients.

Purpose: The goals of this retrospective study were to evaluate the accuracy of core needle biopsy (CNB) for the diagnosis of osteosarcoma and to identify criteria that may predict failed CNB.

Materials And Methods: From 2002 to 2012, 73patients with a total of 73osteosarcomas underwent CNB. Patients demographics and procedure details were recorded, including tumor size, tumor characteristics (hemorrhagic or not, lytic, sclerotic [>50% bone condensation], or mixed), the type of anesthesia, the number of tissue samples, the size of the biopsy needle and pathology report.

Volumetric evaluation of fat resorption after breast lipofilling.

Introduction: The fat transfer or the lipofilling is a technique that had a major impact on the breast surgery results. We have been using this technique since 1998 as an adjuvant in breast reconstruction. The transferred fat is partially resorbed in the first three months after fat grafting.

[Comparison of 3T dacryo-MRI by instillation with dacryo-CT scan for evaluation of epiphora].

Objectives: Epiphora is frequently related to stenosis of the lacrimal drainage pathways. In the evaluation of stenosis, dacryo-CT scan remains the gold standard, despite the need for radiation and catheterization of the lacrimal passages. Evaluation by high field 3T MRI compared to the gold standard in the morphological study of the lacrimal passages and quantification of the stenosis is attractive considering the lack of radiation and non-invasive nature of the technique.
