The availability of computed radiography has opened the possibility of using reduced dosage for radiographs in clinical settings and reducing the retake rate. A prospective controlled study was carried out over a period of four months comparing conventional X-rays and computed radiography. The aim was to assess if computed radiography at 50% normal dosage would result in films of adequate quali...

Objective – Technological improvement is usually followed by comparisons between conventional and new. Those who work with radiographic assessment, such as cephalometric analysis for orthodontic diagnosis, have been living a new challenging and learning phase since the introduction of digital images. It is possible to obtain reproducible and clear images with digital radiography, but radiograph...

PURPOSE To compare the diagnostic accuracy of radiography, to radiography equivalent dose multidetector computed tomography (RED-MDCT) and to radiography equivalent dose cone beam computed tomography (RED-CBCT) for wrist fractures. METHODS As study subjects we obtained 10 cadaveric human hands from body donors. Distal radius, distal ulna and carpal bones (n = 100) were artificially fractured ...

INTRODUCTION Low fetuin-A and vitamin D and high monounsaturated fatty acid (MUFA) contents are associated with vascular calcification (VC) in dialysis patients. We aimed to demonstrate the difference in fetuin-A, vitamin D, MUFA, and VC on plain radiography between patients on hemodialysis and peritoneal dialysis (PD). MATERIALS AND METHODS We recruited 31 hemodialysis and 30 PD patients. We...

Percutaneous balloon kyphoplasty (PBKP) is generally performed under two-dimensional (2D) radiography guidance (lateral- and anteroposterior (A-P) views) using C-arm fluoroscopy. However, 2D images taken by single-plane or bi-plane fluoroscopy cannot provide information regarding axial views, particularly the Z axis. Lack of information regarding the Z axis prevents the creation of three-dimens...

Conventional radiography has been for decades the standard method of evaluation for cervical spine trauma patients. However, currently available helical multidetector CT scanners allow multiplanar reconstruction of images, leading to increased diagnostic accuracy. The purpose of this study was to determine the relative benefit/risk ratio between cervical spine CT and cervical spine radiography ...
