a 52-year-old post-menopausal female was admitted to the emergency room due to acute onset of abdominal pain in the right lower quadrant. there was no history of trauma of the abdomen. contrast-enhanced multi-detector computed tomography (mdct) of the abdomen and pelvis revealed a massive right retroperitoneal hematoma and contrast extravasation from a right ovarian artery aneurysm. digital sub...

objectives: new digital two-dimensional imaging systems are considered as an easily accessible modality for sinonasal evaluation. the aim of this study was to assess the diagnostic efficacy of digital waters’ and caldwell’s radiographic views for evaluation of sinonasal area. materials and methods: a total of 273 patients fulfilling the inclusion criteria were enrolled in this descriptive-analy...

Introduction: The measurement precision of jaw is important for surgery or installing implants. Preimplant radiographs are important part of clinical evaluations before implant surgery. For choosing location, we should consider the important anatomical structures like mental foramen, inferior alveolar canal, nasal cavity and maxillary sinus.It is important to know the measurement accuracy of ra...

Background and Aim: Cone beam computed tomography (CBCT) produces high-quality data in periodontal diagnosis and treatment planning. The aim of this study was to compare the accuracy of CBCT with intraoral digital and conventional radiography in the measurement of periodontal bone defects.  Methods and Materials: In this diagnostic research, two hundred and eighteen artificial osseous d...

  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 . ...

Radiologic procedures used to evaluate patients with suspected glomus tumor have included plain skull radiography, temporal bone tomography, computed tomography, and cerebral angiography. Of these, only angiography has proven reliable as a screening procedure for small glomus tympanicum and jugulare tumors. Digital subtraction angiography was used as the initial examination for suspected paraga...

statement of the problem in order to replace lost tooth of patients, we use dental implants which are common. therefore, accurate measuring of bone height and width before placing implants is necessary. the aim of this study is evaluating the accuracy of linear and spiral tomography in careful determination of implant site sizes in comparison with gold standard (cbct). material and methods this...
