Osteoarthritis (OA) is a common degenerative musculoskeletal disease highly prevalent in aging societies worldwide. Traditionally, knee OA is diagnosed using conventional radiography. However, structural changes of articular cartilage or menisci cannot be directly evaluated using this method. On the other hand, ultrasound is a promising tool able to provide direct information on soft tissue deg...

conclusion dt-sfp can improve the detection of relatively early bone abnormalities in acetabular and proximal femur compared with conventional radiography. dt-sfp can also observe the abnormal impact between acetabular and proximal femur. patients and methods ninety-four consecutive patients with discomfort around the hip joint underwent dt-sfp and conventional radiography. the imaging features...

Introduction Radiation protection is an important safety issue for radiographers and patients. The aim of this study was to assess the observance of radiation protection regulations in radiology departments of Kermanshah University of Medical Sciences, Kermanshah, Iran. Materials and Methods In total, 48 radiographers and 8 radiography rooms were evaluated in three hospitals of Kermanshah, Iran...

Diagnostic imaging plays an important role in characterization of focal and diffuse hepatic diseases. Radiography and ultrasound (US) serve as first-line diagnostic imaging modalities of choice for the detection and characterization of hepatic diseases, however the majority of findings using these imaging tests are often non-specific. The identification of focal mass lesions in the liver using ...

OBJECTIVE To evaluate and compare the diagnostic efficiency of a digital radiographic system (RadioVisioGraphy -RVG-) in combination with a diagnostic assisting program (Logicon) with RVG in basic mode, magnification and conventional radiography (Kodak). STUDY DESIGN A study was made of 384 proximal surfaces corresponding to 192 posterior teeth. The diagnostic techniques employed comprised Ko...

OBJECTIVES This study sought to assess the diagnostic accuracy of cone beam computed tomography (CBCT) with different voxel sizes and intraoral digital radiography with photostimulable phosphor (PSP) plate for detection of periapical (PA) bone lesions. MATERIALS AND METHODS In this ex vivo diagnostic study, one-millimeter defects were created in the alveolar sockets of 15 bone blocks, each wi...

With our study we wanted to compare the diagnostic accuracy of conventional radiography (orthopanoramic and intraoral radiography) and Cone Beam CT (CBCT) for the diagnosis of periapical lesions on the posterior elements of the upper maxilla endodontically treated.The images were analyzed by a radiologist and an endodontist whose interpretation of radiological examinations is unique. Were exami...

Digital radiography has become the norm in U.S. hospitals. The ability to view images, postprocess, and transmit the images systemwide immediately are distinct advantages. Yet, these technical advances create challenges for the radiology community, including the need to re-educate the workforce and prevent unnecessary radiation exposure. This education process is even more important for those w...

Since the past few years, dental implants have gained popularity as best treatment option for missing teeth. Accurate diagnosis and planning plays a key role in successful implant placements. Radiography is most widely used method assessing quality quantity of bone site. Selection proper diagnostic imaging modality their adequate interpretation very important planning. With evolution different ...

In this meta-analysis we included 32 English-language articles published between January 1975 and June 2004 on the diagnostic performance of plain radiography, subtraction arthrography, nuclear arthrography and bone scintigraphy in detecting aseptic loosening of the femoral component, using criteria based on the Cochrane systematic review of screening and diagnostic tests. The mean sensitivity ...
