245. Technical Assessment of Brain SPECT Machine, SET-070

Preoperative assessment of meningioma aggressiveness by Thallium-201 brain SPECT

Introduction: Meningioma is usually a benign brain tumor, but sometimes with aggressive course. The aim of this study was to assess the ability of 201Tl Brain SPECT to differentiate the pathologic grade of meningioma preoperatively. Methods: Thirty lesions in 28 patients were evaluated in this study. Early (20 minutes) and late (3 hours) brain SPECT images were performed and early u...

Technical aspects of myocardial SPECT imaging.

Myocardial perfusion SPECT imaging accounts for well over 90% of all myocardial perfusion imaging performed in the United States today. Although clearly superior to the traditional planar technique in terms of image contrast and consequent diagnostic and prognostic yield, the SPECT approach also involves additional acquisition and processing steps. This article concisely describes the entire te...

6 . 245 : MULTIVARIABLE CONTROL SYSTEMS by A . Megretski Problem Set

Technical overview of brain SPECT imaging: improving acquisition and processing of data.

The purpose of this article is to give a basic understanding of imaging setup, postprocessing procedures, and anatomy for brain SPECT. After reading the article, the nuclear medicine professional should be able to describe the normal anatomy of the brain; the localization of radiopharmaceutical complexes within the brain; good techniques for image acquisition; and the concepts of filtered backp...
