Pulsatile Electrical Impedance Tomography for Diagnosis and Monitoring of Acute Pulmonary Embolism

NCT07724197 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 275

No results posted yet for this study

Summary

This multicenter observational diagnostic study aims to evaluate pulsatile electrical impedance tomography (EIT) for the diagnosis and monitoring of acute pulmonary embolism. The study includes a retrospective phase and a prospective phase. EIT-derived ventilation-perfusion matching index, dead-space ventilation index, and intrapulmonary shunt index will be compared with CT pulmonary angiography and relevant clinical indicators. The study is designed to assess whether EIT can provide a noninvasive, bedside, radiation-free method for pulmonary embolism diagnosis, risk stratification, and dynamic treatment monitoring.

Pulsatile Electrical Impedance Tomography

Pulsatile electrical impedance tomography will be used to obtain EIT-derived parameters, including the ventilation-perfusion matching index, dead-space ventilation index, and intrapulmonary shunt index. These parameters will be compared with CT pulmonary angiography and clinical indicators to evaluate the diagnostic performance, risk stratification value, and dynamic monitoring value of EIT in acute pulmonary embolism. This diagnostic assessment does not assign participants to treatment and does not alter routine clinical management.
