Objective: This study aimed to evaluate chest computed tomography (CT) angiography image quality using the contrast enhancement (CE)-boost technique compared with conventional images.
Methods: Forty patients who underwent contrast-enhanced chest CT were included. Combined CT angiography images of the iodinated image obtained from the subtraction of nonenhanced CT images and CT angiography images were used to generate CE-boost images. Computed tomography attenuation, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) for the right and left pulmonary arteries as the central and subsegmental arteries as peripheral vessels were assessed. Subjective image quality was rated on a 5-point scale by 2 radiologists. Image quality was assessed using a paired t test.
Results: Computed tomography attenuation in the main pulmonary artery was significantly higher for the CE-boost images (311.05 ± 91.94) than for the conventional images (221.25 ± 61.21, P < 0.001). Similarly, the CE-boost images resulted in significantly higher CT attenuation in the subsegmental arteries (right, 305.34 ± 90.13; left, 313.05 ± 97.21) than in the conventional images (right, 218.45 ± 63.16; left, 223.89 ± 74.27). The CE-boost technique demonstrated marked improvement in the visualization of the peripheral pulmonary artery without the administration of a higher iodine delivery rate. The mean SNR and CNR were also significantly higher in the central and peripheral vessels in the CE-boost images than in the conventional images (P < 0.001). In the subjective analysis, the image contrast and vascular contrast edge were significantly higher for the CE-boost images than for conventional images (P < 0.001).
Conclusions: The CE-boost technique increases not only the visualization of peripheral arteries by improving vascular attenuation but also the SNR and CNR.

Assessment of vascular invasion of pancreatic ductal adenocarcinoma based on CE-boost black blood CT technique.
Insights Imaging
December 2024
Department of Radiology, China-Japan Friendship Hospital, Beijing, China.
Article Synopsis
- This study investigates the effectiveness of two advanced imaging techniques, AiCE and AIDR 3D, combined with or without the black blood CT (BBCT) approach, for detecting vascular invasion in patients with nonmetastatic pancreatic ductal adenocarcinoma (PDAC).
- A total of 35 patients underwent contrast-enhanced abdominal CT scans, with images analyzed for quality and diagnostic performance by two observers, using metrics like Cohen's kappa and area under the curve (AUC) for evaluation.
- The findings indicate that the combination of AiCE and BBCT significantly improves image quality and diagnostic accuracy for detecting vascular invasion, demonstrating high sensitivity and specificity, which could influence treatment decisions for patients with PDAC.

Article Synopsis
- This study aimed to compare the effectiveness of a double contrast enhancement (CE)-boost technique versus traditional methods for improving vascular imaging in lower-extremity CT angiography.
- A total of 45 patients participated, and the double CE-boost technique was found to significantly reduce image noise and enhance CT attenuation values, resulting in clearer images.
- The results showed that double CE-boost images had superior quality, higher signal/noise ratios, and better subjective ratings compared to both conventional and single CE-boost images.

Article Synopsis
- - The study aimed to assess how the contrast-enhancement-boost (CE-boost) technique affects image quality in obese patients during computed tomography pulmonary angiography (CTPA) compared to two other methods: hybrid iterative reconstruction (HIR) and model-based iterative reconstruction (MBIR).
- - Conducted on 100 patients, the results indicated that CE-boost significantly improved visibility and CT values over HIR and MBIR in both obese and non-obese patients, with MBIR showing the least image noise.
- - Ultimately, CE-boost outperformed HIR regarding diagnostic confidence and vascular contrast, suggesting it is particularly effective for enhancing pulmonary artery imaging in obese individuals.
