UNLABELLED The aim of this study was to introduce a new quantification method for 153Sm-ethylenediaminetetramethylenephosphonate (EDTMP) and 186Re-(tin)1,1-hydroxyethylidene diphosphonate (HEDP) to separately measure bone uptake and soft-tissue retention of these radiopharmaceuticals. METHODS Studies were performed on 23 men and 6 women undergoing radionuclide therapy for palliation of bone p...

We developed a method for suppression of the contrast of ribs in chest radiographs by means of a massive training artificial neural network (MTANN). The MTANN is a trainable highly nonlinear filter that can be trained by using input chest radiographs and the corresponding teacher images. We used either the soft-tissue image or the bone image obtained by use of a dual-energy subtraction techniqu...

The purpose of this article is to describe the use of shortening and angulation to manage composite bone and soft tissue loss associated with combat-related type IIIB open tibia fractures. Four patients underwent placement of a software-driven circular fixator with acute shortening and angulation to manage composite bone and soft tissue loss. Frames were applied using the Rings First Method, an...

OBJECTIVES The purpose of this study was to determine buccal bone and soft tissue thicknesses and their correlation in the maxillary anterior region using cone beam computed tomography (CBCT). MATERIALS AND METHODS In this cross sectional study, 330 sound maxillary incisors in 60 patients with a mean age of 37.5 years were assessed by CBCT scans. For better visualization of soft tissue, patie...

introduction:the use of beta emitters is one of the effective methods for palliation of bone metastasis. the risk of normal tissue toxicity should be evaluated in the bone pain palliation treatment. methods: in this study, the monte carlo simulation code mcnpx was used for simulation a bone phantom model consisted of bone marrow, bone and soft tissue. specific absorbed fractions were calculated...

PURPOSE Surgery of irradiated tissue has an increased complication rate because of the development of hypovascular, hypocellular, and hypoxic tissue. This study was undertaken to perform histopathologic and histomorphometric analyses of irradiation tissue injury in bone and the surrounding soft tissues. MATERIAL AND METHODS The histopathologic findings of 40 human mandibular bones and the sur...
