Summary
Optimizing chest computed tomography (CT) protocols significantly reduced radiation dose in COVID-19 pneumonia patients. A simple educational intervention and clinical audit proved effective for dose optimization.
Area of Science:
- Radiology
- Medical Imaging
- Radiation Safety
Background:
- Chest computed tomography (CT) is vital for diagnosing and managing COVID-19 pneumonia.
- Increased CT use raises concerns about overuse, protocol standardization, and radiation exposure.
Purpose of the Study:
- To develop and implement an optimized chest CT protocol.
- To reduce radiation dose in adult patients with suspected or confirmed COVID-19 infection.
Main Methods:
- A clinical audit was employed in a rural Indian tertiary care hospital.
- An optimized chest CT protocol was implemented, followed by pre- and post-intervention audits.
- Radiation dosimetry data and scan parameters were analyzed before and after the intervention.
Main Results:
- The optimized protocol was clinically adequate with good inter-rater reliability.
- Radiation dose, measured by CTDI-vol and DLP, significantly decreased across audit cycles (P < 0.001).
- Compliance improved after reinforcement, demonstrating the effectiveness of the educational intervention.
Conclusions:
- Clinical audit effectively provided feedback for optimizing chest CT radiation doses.
- A straightforward educational intervention successfully achieved radiation dose optimization for COVID-19 patients.

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (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...
