Purpose: This paper aims to realize an analysis of available radio-imaging methods for outlining various forms of pulmonary embolism (acute or chronic) with highlights on the semiology and adequate medical indications. Methods: There are several types of radiological examinations used in the evaluation of pulmonary embolism such as perfusion scintigraphy V/Q, digital subtraction angiography, co...

introduction: various systems for intraoral digital radiography have been available as an alternative to film–based radiography. in consideration of several advantages of digital radiography such as less patient absorbed dose, manipulation of im age quality and elimination of processing, it has been extensively used in different fields of denti stry in recent years. the purpose of this study wa...

objective: diagnosis of vertical root fractures (vrfs) is critical in endodontics which most of the times occurs in endodontically treated teeth with root canal fillings such as gutta percha. despite cone beam computed tomography (cbct) has significantly enhanced image quality compared to digital radiography (dr) which aid the diagnosis, artifacts has remained as a problem in vrf detection . th...

Introduction: The study was undertaken to evaluate the practice of chest radiography using different digital imaging systems and its influence on dose and image quality.  Materials and Methods: The study was carried out in two hospitals from March 2016 to June 2016. Sixty ambulatory patients aged 21 to 60 years who were able to cooperate without difficulty and weighed between 60 to 80 kg were ...

Introduction: The aim of this study was to compare digital and conventional radiography in determining the working length of dilacerated canals.Methods: Thirty nine human extracted single-rooted teeth with root curvature more than 35 degrees were included in this study. After access preparation, a file was inserted into the canal and advanced until the file tip was visualized at the foramen. Wi...

objectives: this study aimed to assess the diagnostic value of conventional and digital radiography for detection of cavitated and non-cavitated proximal caries. materials and methods: fifty extracted human premolars and molars were mounted in a silicone block. charge-coupled device (ccd) and photostimulable phosphor plate (psp) receptors and intra-oral films were exposed with 60 and 70 kvp wit...
