introduction: the exact measurement of the root canal length is of great importance in root canal therapy. although, determination of the root canal length through radiography is the most common method, recently electronic apex locators are being used to determine working length and decrease the number of radiographs. the purpose of this study was to compare the accuracy of an electronic apex l...

There is a diversity of modalities available for the imaging of soft tissue and skeletal sarcomas. However, conventional radiography remains the first line imaging modality in the diagnostic work-up, as it provides superior spatial resolution for the evaluation of bone trabecular detail. This article focuses on the advanced imaging modalities of computer tomography, magnetic resonance imaging, ...

A 36-year-old woman presented with lower extremity paralysis. Her past medical history included gout. Conventional radiography and MR imaging revealed bone erosion and soft tissue lesions of the thoracic spine. Fluorodeoxyglucose-positron-emission tomographic (FDG-PET) images revealed hypermetabolic lesions of the thoracic spine. A CT-guided biopsy was diagnostic for inflammatory tophaceous gou...

introduction: evidence-based education has been introduced to dentistry as a new educational tool. however, its effectiveness should be evaluated in different educational topics. the aim of this study was to compare the effects of evidence-based and conventional education on radiography assessment before endodontic treatment. methods: in this semi-experimental study 75 senior dental students of...

BACKGROUND Radiography plays an important role in the detection of interproximal caries. OBJECTIVES The aim of the present study was to determine diagnostic accuracy of chargecoupled devices (CCD), Photo Stimulable Phosphor (PSP) and film radiography in detecting non-cavitated caries. PATIENTS AND METHODS Seventy-two non-cavitated approximal surfaces of extracted human posterior teeth were ...

The only sign of chronic apical periodontitis is periapical lesions that are seen in radiographs. Lesions are visible when the inflammation reaches cortical plates. Lesions located in cancellous bone, cannot be easily seen in radiography. Developing computerized technology in radiography, which has numerous advantages and its show up devices in the market, encourage the clinicians to take advan...

The shoulder is one of the most complex joints in the human body and, as such, presents an evaluation and diagnostic challenge. The first steps in its evaluation are obtaining an accurate history and physical examination and evaluating conventional radiography. The use of other imaging modalities (eg, ultrasound, magnetic resonance imaging and computed tomography) should be based on the type of...

Muhammed Alshamari (2016): Low-dose computed tomography of the abdomen and lumbar spine. Örebro Studies in Medicine 137. Radiography is a common radiologic investigation despite abundant evidence of its limited diagnostic value. On the other hand, computed tomography (CT) has a high diagnostic value and is widely considered to be among the most important advances in medicine. However, CT expose...

background: healing of critical-sized defects (csds) is one of the major challenges facing orthopedic surgeons. to assess the bone healing process usually plain radiography is used. serial radiography results in certain side effects and recent findings are indicating the early detection of bone healing via ultrasonography. objectives: the purpose of current study is to compare the diagnostic ac...
