Use of Ultrasonic Parameters as Adjuvant Tool of Diagnosis and Monitoring of Bone Lesions

چکیده
Ultrasound parameters were proposed to characterize femur in vitro from rats. Six quantitative parameters (Apparent Integrated Ultrasonic Backscatter AIB, Frequency Slope of Apparent Backscatter – FSAB, Temporal Slope Apparent Backscatter TSAB, Integrated Reflection Coefficient IRC, Slope and Frequency Integrated Reflection FSIR and Temporal Slope Reflection Coefficient TSRC) were applied to the echo from the cortical and trabecular bone in twelve femur diaphyses in vitro from Wistar rats. The US signal is acquired from 5 previous chosen positions along the femur. The results showed that their values statistically belong to the same group. This is an indication that the proposed method (from acquisition protocol to parameter estimation) has potential to characterize bone tissue in animal models.

Differentiation of Cocaine-Induced Midline Destructive Lesions from ANCA-Associated Vasculitis
Introduction: Cocaine-induced midline destructive lesions (CIMDL) are complications of regular nasal cocaine inhalation. CIMDL can mimic systemic diseases with positive anti-neutrophil cytoplasmic antibodies (ANCA), such as granulomatosis with polyangiitis (GPA). Case Report: In this article, we describe the case of a young woman who presented with nasal perforation induced by cocaine, al...

Repeated bone marrow examination was found to be of value in assessing response to treatment in megaloblastic anemia. The objective of this study was monitoring the response of megaloblastics to treatment, concerning the location of neutrophilic myeloperoxidase and myeloperoxidase index (MPXI) and their variation in megaloblastic erythroid progeny. It is possible to follow up megaloblastic ...
