The retention indices of 201Tl-SPECT in brain tumors.
OBJECTIVE The aim of this study was to assess the utility of 201Tl SPECT in the differential diagnosis of intracranial tumors and to determine the relationship between 201Tl uptake and histological types. METHODS Thirty-eight patients (19 males and 19 females) with thirty-eight brain tumors were evaluated with 201Tl-SPECT. The early and delayed 201Tl uptake ratio was calculated, and the reten...
متن کاملCharacterization of cartilaginous tumors with 201Tl scintigraphy.
UNLABELLED Histological diagnosis and grading of cartilaginous tumors are closely correlated with patient prognosis; consequently, they are essential elements. We attempted to clarify the characteristics of 201Tl uptake in various histological types of cartilaginous tumors and to assess its clinical value. METHODS Twenty-two cases with histologically proven cartilaginous tumors (3 enchondroma...
متن کاملAccuracy of exercise 201Tl myocardial scintigraphy in asymptomatic young men.
BACKGROUND Little is known about the diagnostic usefulness of 201Tl scintigraphy for detecting asymptomatic coronary artery disease in apparently healthy men. We thus evaluated planar 201Tl exercise myocardial scintigraphy in 845 asymptomatic male military aircrew undergoing coronary arteriography because of abnormal noninvasive tests suggesting possible myocardial ischemia. METHODS AND RESUL...
متن کاملComputerized Addenbrooke’s Cognitive Examination for Neurocognitive Monitoring of Children with Benign and Malignant Brain Cerebellar Tumor
Background: Brain tumors in the cerebellum site, especially in the cranial nuclei, are most commonly associated with cognitive impairment in children, but the differences in dimensions of cognitive impairments in pediatric benign and malignant tumors are rarely studied. Meanwhile, cognitive impairments in this area are required to be widely studied. This study aimed at using Computerized Addenb...
متن کاملDiagnosis of brain tumor using PNN neural networks
Cells grow and then need a very neat method to create new cells that work properly to maintain the health of the body. When the ability to control the growth of the cells is lost, they are unconsidered and often divided without order. Exemplified cells form a tissue mass called the tumor. In fact, brain tumors are abnormal and uncontrolled cell proliferations. Segmentation methods are used in b...
