Single photon emission computed tomography in tuberculous meningitis

Single photon emission computed tomography in tuberculous meningitis.

INTRODUCTION Data on single photon emission computed tomography (SPECT) in tuberculous meningitis are lacking and prompted this study. SPECT findings in tuberculous meningitis are reported and correlated with clinical and radiological findings. PATIENTS AND METHODS Seventeen patients with tuberculous meningitis that was diagnosed on clinical, radiological, and laboratory criteria have been in...

Single Photon Emission Computed Tomography

Positron emission tomography and single photon emission computed tomography.

Neuroimaging techniques have had a dramatic impact on the evaluation and treatment of patients with epilepsy. In order to take full advantage of their potential, it is important to place them in clinical and electrophysiological context and to understand their technical limitations. Positron emission tomography with 18F-2-deoxyglucose and single photon emission computed tomography can provide v...

Image Optimization in Single Photon Emission Computed Tomography by Hardware Modifications with Monte Carlo Simulation

Introduction: In Single Photon Emission Computed Tomography (SPECT), the projection data used for image reconstruction are distorted by several factors, including attenuation and scattering of gamma rays, collimator structure, data acquisition method, organ motion, and washout of radiopharmaceuticals. All these make reconstruction of a quantitative SPECT image very difficult. Simulation of a SP...

Single photon emission computed tomography tracer.

Single photon emission computed tomography (SPECT) is the state-of-the-art imaging modality in nuclear medicine despite the fact that only a few new SPECT tracers have become available in the past 20 years. Critical for the future success of SPECT is the design of new and specific tracers for the detection, localization, and staging of a disease and for monitoring therapy. The utility of SPECT ...
