Purpose To evaluate the feasibility and practical utility of abdominal lead placement as an alternative for precodium in ECG gated cardiac CT. To estimate the environmental and financial benefits of this novel technique in comparison with the traditional method.
Read more Methods and materials All patients who underwent ECG (Electrocardiogram) gated cardiac CT (computed tomography) were inluded in the study. This cohort included a broad spectrum of clinical indications, such as CT coronary angiography (CTCA), aortography, coronary artery calcium scoring, and complex multi-regional angiographic assessments, including triple rule-out CT (TRO-CT). The study specifically excluded pediatric patients and young adults (<18 years) The study was performed over a period of 6 months. Instead of the traditional ECG lead placement over the precordium, they were placed over the abdomen....
Read more Results A total of 8,432 ECG-gated studies were conducted utilizing this novel approach Among these cases, only eight instances (0.09%) necessitated a transition from abdominal to conventional chest ECG lead placement due to erratic or unreliable signal acquisition A comprehensive retrospective analysis was conducted to determine potential contributory factors, including patient-specific anatomical and physiological variations, body mass index, presence of arrhythmias, and signal acquisition inconsistencies. However, no definitive patterns or shared characteristics were discerned among these cases, suggesting that the abdominal ECG lead placement...
Read more Conclusion Sustainability in radiology encompasses the implementation of environmentally conscious practices that minimize ecological impact while ensuring optimal diagnostic accuracy, patient care, and resource utilization In the context of modern healthcare systems, the integration of sustainable methodologies is of paramount importance. As part of our institutional commitment to eco-friendly imaging protocols, we adopted an innovative electrocardiogram (ECG) lead placement technique for ECG-gated computed tomography (CT) studies, wherein leads were positioned on the anterior abdominal wall instead of the conventional precordial region This study...
