purpose: to record the mri features of primary central nervous system lymphoma (pcnsl) and compare these properties in monofocal and multifocal disease. methods: eleven cases of monofocal disease were compared to 9 cases of multifocal disease. all patients were examined by non-enhanced and contrast-enhanced mri. tumor location, signal intensity, enhancement characteristics, age distribution, pe...

the aim of this study was to reveal biometric peculiarities of new zealand white rabbit antebrachium (radius and ulna) by means of three-dimensional (3d) reconstruction of multidetector computed tomography (mdct) images. under general anesthesia, the antebrachiums of a total of sixteen rabbits of both sexes were scanned with a general diagnostic mdct. biometric measurements of the reconstructed...

conclusions our findings may be applied by manufacturers to design prostheses more compatible with asian populations. alterations to the shape of components should be considered to provide optimal coverage. patients and methods during 2013, 150 consecutive patients (96 males and 54 females) from the outpatient department of orthopedic surgery of rasoul akram hospital with knee ct scans were stu...

introduction: this study aims at examining the difference of pharyngeal airways in patients with different occlusion postures, hoping to im prove diagnostic methods and provide a stable treatment plan for orthodontic patients. materials and methods: the data were ga-thered through cbct radiographies of patients from a specialized center for radiology. in each occlusion group according to the pe...

introduction: panoramic view as a routine dental radiograph has an important role in diagnosis of other facial abnormalities accompanied with dento- alveolar structures. in this case presentation, we discuss this subject and also the efficacy of cone-beam computed tomography in localization of foreign body in complex anatomy of nasal cavity.

background percutaneous catheter drainage (pcd) and percutaneous needle aspiration (pna) have become the primary options for treating hepatic abscesses. thus far, various studies have examined the clinical data and computed tomography (ct) features for predicting pcd outcomes. objectives the goal was to compare ct features between hepatic abscesses classified based on strain and quantitative ou...

objectives : bone assessment is essential for diagnosis, treatment planning and prediction of prognosis of periodontal diseases. however, two-dimensional radiographic techniques have multiple limitations, mainly addressed by the introduction of three-dimensional imaging techniques such as cone beam computed tomography (cbct). this study aimed to assess the accuracy of cbct for detection of marg...

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...
