Statement of Problem: Computed tomography (CT) has proved to be the most precise method to evaluate the quantity of jaw bones.In recent years, patient dose which is much more greater in CT than conventional methods has attracted more attention, and has brought the idea of using the conventional method in more accurate ways or applying new methods with lower doses.Purpose:radiovisiography for pr...
Background and Aims: Conventional radiological equipments in our country are going to be converted to digital system using computed radiology (CR) technology. If we know the accuracy of digital panoramic radiography for detection of small defects in tooth, it will be useful in cases with difficulty for taking the intraoral radiographs. The aim of this study was to evaluate sensitivity and speci...
The goal of this study was to establish local diagnostic reference levels (LDRLs) for conventional radiography examinations in Sistan-Baluchestan province of Iran, using dose area product (DAP) measurements followed by a comparison with international dose levels. DAP factor evaluation was carried out at eight radiography rooms in six public and one private health-care centers. The study employe...

OBJECTIVE To investigate the clinical feasibility of dual energy subtraction (DES) imaging to improve the delineation of the vocal cord and diagnostic accuracy of vocal cord paralysis as compared with the anterior-posterior view of flat panel detector (FPD) neck radiography. MATERIALS AND METHODS For 122 consecutive patients who underwent both a flexible laryngoscopy and conventional/DES FPD ...
Increasingly, veterinarians are using medical imaging to diagnose their patients. There is a corresponding tendency towards replacing conventional film-screen systems with digital medical imaging systems, such as computed radiography (CR) and direct radiography (DR). With these systems, many veterinarians around the world are enjoying considerable benefits, including time savings and optimal im...
OBJECTIVE To compare magnetic resonance imaging (MRI), conventional radiography, and ultrasonography in identifying bone erosions in patients with juvenile idiopathic arthritis (JIA), and to determine the validity and reliability of an MRI scale in detecting and grading joint damage. METHODS In 26 JIA patients, the clinically more affected wrist was studied with MRI, radiography, and ultrason...
The approach to the differential diagnosis of rheumatic diseases using conventional radiography is systematic and module-oriented, which, with respect to future developments, forms the basis for computer-assisted diagnosis (CAD). The indications follow consensus-based referral criteria and attempts should be made to raise the evidence level of the recommendations. Investigation techniques have ...
