Purpose:
Emergency departments (EDs) worldwide face crowding, which negatively affects patient care. Diagnostic imaging plays a major role in management of ED patients and contributes to patients' length of stay at the ED. In this study, the impact of Lean-driven interventions on the imaging process at the ED was assessed.
Methods:
During a 6-month multimodal intervention period, Lean-driven interventions and a dedicated radiologist present at the ED were implemented during peak hours (12 a.m.-8 p.m.). Data concerning patient population, radiology department turnaround time (RDTT), radiology report time (RRT), and examination time (ET) for ED patients were compared with a control period of 6 months 1 year earlier.
Results:
RDTT, RRT, and ET were significantly shorter in the intervention period compared with those in the control period. Median RDTT was respectively 36 min (interquartile range (IQR) 24-56) and 70 min (IQR 39-127), RRT 11 min (IQR 6-21) and 37 min (IQR 15-88), and ET 22 min (IQR 14-35) and 23 min (14-38).
Conclusion:
Lean-driven interventions on the imaging process at the ED significantly reduced RDTT, RRT, and ET.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
