Radiologists frequently recommended additional imaging examinations (RAI) in inpatient CT and US scans, particularly for chest CT. Radiologists' experience level inversely impacted RAI rates, suggesting a need for further investigation.
Area of Science:
- Radiology
- Medical Imaging
- Health Services Research
Background:
- Radiologists' additional recommended imaging examinations (RAI) are common in inpatient settings.
- Understanding factors influencing RAI is crucial for optimizing diagnostic pathways.
Purpose of the Study:
- To quantify the rate of RAI in hospital inpatients undergoing CT and US.
- To investigate the impact of clinical variables on RAI rates.
Main Methods:
- Retrospective analysis of 1996 inpatient CT and US examinations.
- Manual extraction of RAI data from radiology reports.
- Inclusion of radiologist experience, patient demographics, and clinical information.
Main Results:
- 34% of examinations included RAI.
- Chest CT, PET-CT, abdominal CT, and abdominal MRI were most frequent for RAI.
- RAI rates were inversely correlated with radiologists' years of experience.
- Pneumonia follow-up showed high RAI for lung nodules.
Conclusions:
- A significant percentage of inpatient CT and US reports included RAI.
- Radiologists' experience is a key factor influencing RAI.
- Further research is needed to validate findings and assess clinical actionability of RAI.

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...

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...
