CT evaluation of patients with hemoptysis and normal chest radiograph

Background and objectives: to study the diagnostic accuracy of Computed Tomography in evaluation of various etiologies of hemoptysis with normal chest radiographs. Methods: Two hundred patients with hemoptysis and normal chest radiograph were evaluated with computed tomography from the period of December 2008 to October 2009. The patients were categorized according to the primary etiology and s...

Computed tomography with normal chest radiograph in tuberculous infection.

Children with primary tuberculosis infection without disease must be identified and treated preventively to avoid an increase in the incidence of tuberculosis in children. However, the recognition of infected cases without disease is often difficult. In particular, minimal active disease may be present in many cases but unrecognised on chest radiography. Computed tomography was therefore perfor...

Estimating a Bounded Normal Mean Under the LINEX Loss Function

Let X be a random variable from a normal distribution with unknown mean θ and known variance σ2. In many practical situations, θ is known in advance to lie in an interval, say [−m,m], for some m > 0. As the usual estimator of θ, i.e., X under the LINEX loss function is inadmissible, finding some competitors for X becomes worthwhile. The only study in the literature considered the problem of min...
