A Knowledge-Based Artificial Neural Network for Pulmonary Embolism Diagnosis: Development and Conceptual Aspects
This paper presents the framework and aspects of the development effort for a knowledge-based artificial neural network for diagnosis of pulmonary embolism. The knowledge-based artificial neural network architecture is instantiated and initialized through the modified Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED) criteria, which represent the preeminent collective experient...
متن کاملClinical characteristics of patients with acute pulmonary embolism.
A mong 117 patients with pulmonary embolism (PE) and no prior cardiac or pulmonary disease who participated in the National Heart, Lung, and Blood Institute Prospective Investigation of Puhnonary Embolism Diagnosis (PIOPED) study, combinations of clinical characteristics were identified that were present in nearly all in whom the diagnosis of PE was made.’ We now assess these as well as additio...
متن کاملDiagnostic pathways in acute pulmonary embolism: recommendations of the PIOPED II investigators.
PURPOSE To formulate comprehensive recommendations for the diagnostic approach to patients with suspected pulmonary embolism, based on randomized trials. METHODS Diagnostic management recommendations were formulated based on results of the Prospective Investigation of Pulmonary Embolism Diagnosis II (PIOPED II) and outcome studies. RESULTS The PIOPED II investigators recommend stratificatio...
متن کاملSensitivity and specificity of perfusion scintigraphy combined with chest radiography for acute pulmonary embolism in PIOPED II.
UNLABELLED We used the archived Prospective Investigation of Pulmonary Embolism Diagnosis II (PIOPED II) data and images to test the hypothesis that reading perfusion scans with chest radiographs but without ventilation scans, and categorizing the perfusion scan as "pulmonary embolism (PE) present" or "PE absent," can result in clinically useful sensitivity and specificity in most patients. M...
متن کاملNeural network in the clinical diagnosis of acute pulmonary embolism.
The purpose of this investigation was to test the hypothesis that computer-based pattern recognition can accurately assess the likelihood of acute pulmonary embolism (PE) based on readily obtainable clinical characteristics. Data were obtained from 1,213 patients who participated in the collaborative study of the Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED). Characteristic...
