Abstract:
Retrospective and prospective chart review was conducted to study patient callbacks to the emergency department (ED) based on plain radiograph interpretation discrepancies between radiologists and emergency physicians before and after a continuous quality improvement (CQI) intervention. Patients who were called back to the ED because of radiograph interpretation discrepancies were retrospectively studied. These results were reviewed by a CQI team, which recommended greater communication and consultation. A prospective study was then performed. Before quality intervention, 0.7% of the patients were recalled; 0.4% required recall after quality assurance, a reduction of 42.9% (P = .0001). Emergency physicians in this study had a low percentage of patient recall due to discrepancies in radiologic interpretation. CQI further reduced this percentage. The proficiency of emergency physicians interpreting radiographs validates the current practice of emergency physicians rendering treatment based on their interpretations and supports the notion of emergency physicians billing for this service.

Radiological Investigation I: X-ray and CT
Radiological Investigation II: MRI and Ventilation Perfusion Scan
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...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
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...

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...
