objective: the diagnosis of vertical root fracture (vrf) in endodontically treated teeth is a clinical challenge due to lack of specific clinical and radiographic signs. although radiographic evaluation such as cbct is helpful, intracanal posts can produce artifacts and may impair the quality of cbct scans. this study aimed to compare the diagnostic accuracy of different resolutions of cbct in ...

Introduction: The brain tumor is an abnormal growth of tissue in the brain, which is one of the most important challenges in neurology. Brain tumors have different types. Some brain tumors are benign and some brain tumors are cancerous and malignant. Glioblastoma Multiforme (GBM) is the most common and deadliest malignant brain tumor in adults. The average survival rate for peo...

In this paper energy method is used to calculate rotor response with loose rotating disk on it. System equation of motion is obtained based on energy method and Lagrange equation. Mathematical modeling of loose disk in a rotor bearing system has resulted in terms similar to unbalance and gyroscopic effect in the system equation of motion. The effect of loose disk axial position and orthotropic ...

conclusion we conclude that coronary calcium scoring provided useful information in the management of patients. in cacs less than 100, it has a npv of 87% in excluding significant stenosis in patients with the risk of cad but it does not have enough diagnostic accuracy for surely excluding coronary stenosis, so we should perform a combination of cacs and coronary ct angiography for patients. re...

10 In the past decades Machine Learning tools have been successfully used in 11 several medical diagnostic problems. While they often significantly out12 perform expert physicians (in terms of diagnostic accuracy, sensitivity, and 13 specificity), they are mostly not being used in practice. One reason for this 14 is that it is difficult to obtain an unbiased estimation of diagnose’s reliabil15 ...

In this paper, we explore the possibility to apply machine learning to make diagnostic predictions using discomfort drawings. A discomfort drawing is an intuitive way for patients to express discomfort and pain related symptoms. These drawings have proven to be an effective method to collect patient data and make diagnostic decisions in real-life practice. A dataset from real-world patient case...

Howell (1968) and Howell and Loy (1968) have described the 'fruit machine' method of diagnostic coding which, using a large computer, will code at the rate of 2,000 diagnoses a minute. More recently, the Medical Research Council's Computer Unit has undertaken reprogramming and extension of this 'fruit machine' method to enable coding to be carried out on a medium-sized machine, currently at the...
