  ABSTRACT   Background: While the benefits of Computed Tomography (CT) are well known in accurate diagnosis, those benefits are not risk free. CT is a device with higher patient dose in comparison with other conventional radiological procedures. Is the reduction of exposures by requiring optimization of CT procedures [a principle concern in radiological protection]? In this study, the radiatio...

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 ...

There is still considerable debate about the optimal diagnostic imaging modality for acute pulmonary embolism. If imaging is deemed necessary from an initial clinical evaluation such as d-dimer testing, options include nuclear medicine scanning, catheter pulmonary angiography, and spiral CT. In many institutions, spiral CT is becoming established as the first-line imaging test in daily clinical...

The study represents an evaluation of the ability of spiral and conventional computer tomography in the diagnoseof intraorbitar and intraocular foreign bodies. The study includes 19 patients, aged between 15 and 52 years, 10 men and 9 women, presenting intraocular or intraorbitar foreign bodies or as a result of an traumatic injuries, who addressed the Emergency Hospital N. Oblu Iasi, between S...

In this paper, the three-dimensional geometry of the human cochlea is modeled by the helico-spiral seashell model. The 3-D helico-spiral model, the generalized representation of the Archimedian spiral model, provides a framework for measuring cochlear features based on consistent estimation of model parameters. Nonlinear least square minimization based algorithms are developed for the identific...

The introduction of spiral technology to computed tomography (CT) scanners in the late 1980s has revolutionised the field ofCT. Spiral CT offers definite practical benefits over conventional scanners and has expanded the role of CT through the development of new scanning techniques. CT scanning now rivals magnetic resonance imaging in many areas of investigation, and for some situations is the ...

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.
