OBJECTIVE To report clinical and radiographic graft incorporation capability of bovine freeze-dried bone grafts. METHODS Twenty five patients were enrolled. The mean follow-up was eight years. Grafts were purified and freeze-dried. Clinical analysis was based on the score of Merle d'Aubigné and Postel and an established score criteria for radiographic bone incorporation was used for radiograp...

Real-time digital radiography is an important developmental tendency for radiographic inspection and diagnosis technique, and enhancement of image is the key to improve resolution and sensitivity of radiographic inspection. In this paper, the algorithm and character of Rank-Order filter is discussed with great emphasis. Rank-Order filter is one of nonlinear filter, All the methods are used to p...

Kidney size may be altered in renal diseases, and the detection of kidney size alteration has diagnostic and prognostic values. We hypothesized that radiographic kidney size, the kidney length to the second lumbar vertebra (L2) length ratio, in normal Miniature Schnauzer dogs may be overestimated due to their shorter vertebral length. This study was conducted to evaluate radiographic and ultras...

UNLABELLED Radiographic arthrography and bone scintigraphy are common diagnostic procedures used for evaluating total hip prostheses. In this study, both techniques are combined, and nuclear contrast imaging (nuclear arthrography) is added. The efficacy of the procedures is evaluated. METHODS After intravenous injection of 99mTc-methylene diphosphonate (MDP), standard radiographic arthrograph...

Digital radiographic systems are gaining widespread use in many clinical applications. Digital radiographic detectors vary dramatically with respect to the technologies that they use and the particular implementation. Their performance thus varies from system to system. It is often necessary to characterize the performance of a digital radiographic or mammographic detector for optimization, des...

BACKGROUND AND PURPOSE The discrepancy between symptoms and radiographic severity of knee osteoarthritis (OA) is well described. However, little is known about whether radiographic severity is predictive of the clinical result of nonoperative treatment. We investigated whether radiographic severity and treatment type were associated with improvements in pain after nonoperative treatment of pati...

PURPOSE X-ray exposure should be clinically justified and each exposure should be expected to give patients benefits. Since dental radiographic examination is one of the most frequent radiological procedures, radiation hazard becomes an important public health concern. The purpose of this study was to investigate the attitude of Korean dentists about radiation safety and use of criteria for sel...

OBJECTIVE To determine the effect of femur positioning on radiographic assessment of completeness of excision after femoral head and neck excision (FHNE) in medium to large breed dogs. SAMPLE POPULATION 10 femurs from canine cadavers (body weight > 20 kg). PROCEDURE Complete FHNE was performed on 5 canine femurs. Excision consisting of inadequate removal of the medial distal aspect of the f...
