Preliminary study on the biocompatibility and osteoconductive properties of a new bovine bone graft

Actual. osteol; 13 (2), 2017
To prevent post-extraction resorption and preserve the integrity of the alveolar ridges, the placement of bone grafts at the time of extraction is recommended. Bovine bone grafts are biocompatibile and osteoconductive, allowing new bone apposition by osteoprogenitor cells. Although there are trademarks r...

PET/MRI: a novel hybrid imaging technique. Major clinical indications and preliminary experience in Brazil

Einstein (Säo Paulo); 15 (1), 2017
ABSTRACT In recent years, medical imaging with hybrid techniques has widely accepted and employed in clinical routine. PET/MRI offers significant advantages, including excellent contrast and resolution and reduced ionizing radiation, as compared to well-established PET/CT. Therefore, PET/MRI is a promisi...

Sonographic scoring of solid thyroid nodules: effects of nodule size and suspicious cervical lymph node

Abstract Introduction Ultrasound is the most frequently used imaging method to evaluate thyroid nodules. Sonographic characteristics of thyroid nodules which are concerning for malignancy are important to define the need for fine needle aspiration biopsy or open surgery. Objective To evaluate malignanc...

Targeting personalized medicine in a non-Hodgkin lymphoma patient with 18F-FDG and 18F-choline PET/CT

Summary Early diagnosis and staging of non-Hodgkin lymphoma (NHL) is essential for therapeutic strategy decision. Positron emission tomography/computed tomography (PET/CT) with fluordeoxyglucose (FDG), a glucose analogue, labeled with fluor-18 (18F-FDG) has been used to evaluate staging, therapy response...
