Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED II) Clinical Trials References presented on Clinical Trials Search is not intended to be a substitute for proven healthcare advice, trips or professional assistance by using a real medical. We aren't mDs. Always confer with your physician about Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED II) conditions. Clinical Trials Search.org is a website devoted to listing clinical research studies in human subjects. Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED II) Clinical research trials and Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED II) medical trials take place in hundreds of localities across the U.S.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually evaluate the effectualness of new does drugs. The purpose of the studies / projects is to solve specific human health questions. Clinical trials are a popular way for physicians, government agencies, and private sector companies to discover treatments for all sorts of conditions, such as Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED II). Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED II) Clinical Trials and other clinical trials permit volunteers to access healthcare treatment choices before they are available to the general public. Some times the subjects recieve professional assistance for without cost, and every now and again they are compensated for their time. Sometimes there is a cost for a Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED II) clinical trial. Subjects often receive the most expert healthcare possible for their Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED II) condition. Risks are a reality, nevertheless, and could include additional or frequent dr. calls, healthcare dangers (perhaps life-jeopardising), and/or the treatment being ineffective. Trials are federally governed with stern guidelines to protect clinical trials subjects.

Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED II)
For Condition: Lung Diseases,Venous Thromboembolism,Pulmonary Embolism
Status: Recruiting
Sponsor(s): National Heart, Lung, and Blood Institute (NHLBI) ,
Synopsis: To determine the value of contrast enhanced spiral computed tomography (spiral CT) for the diagnosis of acute pulmonary embolism (PE).
Details: BACKGROUND: Approximately 600,000 Americans sustain pulmonary embolism each year; one-third of these episodes are fatal. Unfortunately, pulmonary embolism is underdiagnosed and, therefore, under-treated. A substantial body of evidence suggests that the diagnosis of pulmonary embolism is not made in the majority of patients in whom it causes or contributes to death. In the main, there are two explanations for the failure to diagnose pulmonary embolism: pulmonary embolism may be clinically silent, and there is no definitive, noninvasive diagnostic test. Indeed, ventilation perfusion lung scans are nondiagnostic in the majority of patients with suspected acute pulmonary embolism. Pulmonary angiography may be used to establish a diagnosis in such patients, but it is underutilized because of a mortality risk around 1 percent. Recently, relatively small studies have suggested that contrast enhanced spiral computed tomography (CT) scanning is a useful diagnostic test for pulmonary embolism, with sensitivity as high as 80 percent and specificity as high as 95 percent. Spiral CT is widely available and much less invasive than pulmonary angiography. If spiral CT could be established as a useful diagnostic test, pulmonary embolism would be diagnosed more effectively and more patients would receive proper treatment. DESIGN NARRATIVE: The study evaluates the role of spiral CT scan in the diagnosis of PE by comparison with a composite reference test, including pulmonary angiography, V/Q lung scan in patients without prior PE and compression ultrasound of the lower extremities in patients with no prior deep venous thrombosis (DVT).
