The article by Gur et al. (1) in this issue of the Journal makes an important contribution to the literature on mammography screening in that it reports no difference in breast cancer detection and recall rates between mammograms read with computeraided detection and those interpreted by a single radiologist without computer-aided detection. Gur et al. present the recall rates and cancer detect...
Background and Aim: Chairside computer-aided design/computer-aided manufacturing (CAD/CAM) systems have become considerably more accurate, reliable, efficient, fast, and prevalent since 1985 when CEREC was introduced. The inceptive restorative material option for chairside CAD/CAM restorations was limited to ceramic blocks. Today, restorative material options have been multiplied and include me...
Introduction: In the lung cancers, a computer-aided detection system that is capable of detecting very small glands in high volume of CT images is very useful.This study provided a novelsystem for detection of pulmonary nodules in CT image. Methods: In a case-control study, CT scans of the chest of 20 patients referred to Yazd Social Security Hospital were examined. In the two-dimensional and ...

background: the aim of this study was to determine the microtensile bond strength (μtbs) of ceramic and composite computer aided design‑computer aided manufacturing (cad‑cam) blocks bonded to dentin using different adhesive strategies. materials and methods: in this in vitro study, 30 crowns of sound freshly extracted human molars were sectioned horizontally 3 mm above the cementoenamel junctio...
Background: Tinnitus known as a central nervous system disorder is correlated with specific oscillatory activities within auditory and non-auditory brain areas. Several studies in the past few years have revealed that in the most tinnitus cases, the response pattern of neurons in auditory system is changed due to auditory deafferentation, which leads to variation and disruption of the brain net...
Molecular modeling is a set of computational techniques for construction of 3D structure of a protein especially membrane bound proteins whose structures can not be elucidated using experimental techniques. These techniques has been applied in the study of membrane metalloproteases for comparing wild and mutated enzymes, docking inhibitors in the catalytic site and examination of binding pocket...
BACKGROUND AND PURPOSE MRA is widely accepted as a noninvasive diagnostic tool for the detection of intracranial aneurysms, but detection is still a challenging task with rather low detection rates. Our aim was to examine the performance of a computer-aided diagnosis algorithm for detecting intracranial aneurysms on MRA in a clinical setting. MATERIALS AND METHODS Aneurysm detectability was e...
