PURPOSE A number of studies have demonstrated the importance of using surgical clips to define the tumour bed in breast boost radiotherapy. In the absence of such clips, other techniques suggested to improve boost location have included CT and ultrasound (US). Determination of the depth of the tumour bed is important in the selection of electron energy. This study was conducted to prospectively...
BACKGROUND The radiographic evaluation of the response to preoperative chemotherapy for bone and soft tissue sarcomas is based mostly on the change in primary tumor size before and after chemotherapy, as is done for many solid cancers. Its prognostic correlation, however, has hardly been validated. METHODS We conducted a retrospective validation study of the Japanese Orthopaedic Association (...
BACKGROUND This paper presents the long-term results of surgical treatment of intra-articular calcaneal fractures, including subjective evaluation, orthopaedic examination and radiographic evaluation. MATERIAL AND METHODS A total of 126 patients with 135 calcaneal fractures were treated surgically at the Department of Traumatology of the Military Medical Institute in Warsaw between 2008 and 2...
repeating x-ray radiographs, as a common problem in radiology units, represent additional, non-billable costs due to increased film, chemistry, and equipment use as well as increased personnel time. furthermore, patients receive additional radiation exposure from repetitions and must remain on the premises until the second exam is completed. compounding the overt negative financial impact on th...
introdouction: the aim of the present study was to investigate image magnification in digital panoramic radiography and assess the effect of anatomical sites on the magnification in both males and females. materials and methods: in this retrospective study, digital panoramic radiographs of 48 patients with 202 implants were investigated. implant diameter and length were measured on panoramic ra...
Background and Aim: Pulpotomy is one of the routine methods for pulp therapy of primary teeth. At present it is a fact that ideal agent for this has not been discovered. The aim of this study was to compare the clinical and radiographic success rates of electrosurgical pulpotomy versus formocresol pulpotomy in human primary molar teeth. Materials and Methods: In this clinical trial study, pulpo...
The Developmental Dysplasia of the Hip (DDH), also know as Congenital Dislocation of the Hip, is common in infants and children and may persist into adulthood. The radiographic interpretation is highly conditioned by appropriate patient positioning and image quality criteria. The main goal of this study is to demonstrate the value of radiographic evaluation of DDH. Through the retrospective ana...
For years, equine surgeons have found equine skull radiography to be a valuable tool in the diagnosis and management of dental disease. The excellent contrast between air, bone, soft tissue, and tooth substance make the head an ideal area for radiographic evaluation. Conventional or standard radiographic projections adequately image the reserve crown apices, lamina dura denta, alveolar space, a...
The prime purpose of this project was to develop and evaluate a method to digitally alter the dynamic range of digital radiographic images. This digital manipulation of the dynamic range can achieve alteration of the displayed contrast and brightness of the digital radiographic image, based on the underlying anatomy within the image. So-called anatomically shaped radiographic contrast-enhanceme...
background diagnosis and accuracy in determining the exact location, extent and configuration of bony defects of the jaw are of utmost importance to determine prognosis, treatment planning and long-term preservation of teeth. if relatively accurate diagnosis can be established by radiography, proper treatment planning prior to treatment procedures will be possible. objectives the aim of the pre...
