BACKGROUND Spiral fractures of the tibia are virtually homogeneous with regard to their pathomorphism. The differences that are seen concern the level of fracture of the fibula, and, to a lesser extent, the level of fracture of the tibia, the length of fracture cleft, and limb shortening following the trauma. While conventional radiographs provide sufficient information about the pathomorphism ...

background: conventional tomography used for evaluation of the small areas of the jaws provides acceptable information. it has some advantages of availability, less radiation dose and costin comparison to computed tomography (ct) and cone beam ct. double emulsion film usuallyused for taking tomograms requires less exposure than single emulsion film; on the other hand,the latter provides more sh...

C-shaped configuration in the upper maillary first molar is an extremely rare appearance (0.12%). This case reports management of the tooth with such a configuration as well as depiction of its internal morpholgy and external morphology through spiral computed tomography and dentascan in the contralateral tooth with similar morphology. After careful clinical observation and confirmation through...

Spiral computed tomography pulmonary angiography is increasingly used in the non-invasive investigation of patients with suspected pulmonary embolism. This review will focus on current techniques and indications with an explanation of the computed tomography signs of pulmonary embolism, possible pitfalls in interpretation and limitations of the technique.

Objective: Multislice computed tomography is an emerging technology with the potential for non-invasive coronary investigation. The aim of this study was to evaluate the feasibility and limitations of multislice computed tomography in the detection of coronary artery disease. Patients and Methods: Multislice computed tomography was performed in symptomatic patients with atypical chest pain and ...
