The absorption spectra of the GAFCHROMIC XR type R radiochromic film measured with reflectance spectroscopy have been investigated in order to analyze the dosimetry characteristics of the film. Like the XR type T film, this film features two peaks in its absorption spectrum, approximately at 676 and 618 nm, whose intensities increase with increasing absorbed dose. When the main absorption peak ...

OBJECTIVE The objective of the present study was to evaluate radiographic changes of the temporomandibular joint (TMJ) in patients with juvenile systemic lupus erythematosus (JSLE) and a control group. PATIENTS AND METHODS Panoramic radiographies of the TMJ of 26 JSLE patients and 28 healthy individuals were evaluated. Multislice computed tomography (MCT) was performed on those patients who p...

ABSTRACT Ritscher-Schinzel Syndrome (RSS) is a clinically variable, autosomal recessive disorder, involving cardiac, cerebellar and craniofacial abnormalities. Numerous reports describe hand changes in RSS patients; however, a detailed characterization of the hands has not previously been performed. OBJECTIVE The purpose of this study was to identify whether specific radiographic hand changes...

INTRODUCTION [corrected] Advanced bone maturation is a radiographic feature that might be encountered in a number of different forms of skeletal dysplasias such as Desbuquois dyspalsia, Larsen syndrome, the Reunion Island form of Larsen syndrome, diastrophic dysplasia, acrodysostosis, Catel-Manzke syndrome, a variant of metatropic dysplasia and Maroteaux-lamy syndrome. CASE PRESENTATION We re...

OBJECTIVE The spinal cord-injured patients begin to present a new configuration of forces on the joints. The hip joint is one of the most affected, because these patients generally use a wheelchair as a means of locomotion. Osteoarticular changes, such as heterotopic ossification, can be found in these patients, as evidenced by radiographic studies. This study aims to identify radiographic chan...

BACKGROUND AIMS Evaluation of: 1. early clinical and radiographic results of total hip arthroplasty (THA) through a standard lateral direct approach, 2. early clinical and radiographic results of THA through a minimal lateral approach, 3. comparison of the results of THA in these two groups. MATERIAL AND METHODS 120 THAs (60 cementless and 60 cemented) done in 120 patients due to degenerat...

Plain chest radiography plays a major role in the diagnosis and follow-up of pulmonary tuberculosis in childhood. The aim of our study was to investigate the distribution of characteristic chest radiographic findings at diagnosis in children with pulmonary tuberculosis. The age of the patients and the type and localization of radiographic changes at admission were retrospectively analyzed. We r...

INTRODUCTION Bisphosphonates inhibit bone resorption by interfering with the action of osteoclasts. Among the adverse effects, sclerotic lines observed in the metaphysis of long bones have been described as the main imaging finding in pediatric patients. OBJECTIVE To evaluate the frequency of radiographic changes caused by alendronate in children and adolescents with low bone density or calci...

OBJECTIVE To (1) evaluate radiographic changes associated with osteoarthrosis (OA) before and after tibial tuberosity advancement (TTA) and (2) determine if these changes are indicative of limb function as determined by kinetic gait analysis. STUDY DESIGN Prospective clinical study. ANIMALS Dogs (n=35) with cranial cruciate ligament (CCL) deficient stifles (38). METHODS Variables recorded...

The Hilbert polynomial can be defined axiomatically as a group homomorphism on the Grothendieck group K(X) of a projective variety X, satisfying certain properties. The Chern polynomial can be similarly defined. We therefore define these rather abstract notions to try and find a nice description of this relationship. Introduction Let X = P be a complex projective variety over an algebraically c...
