Significats de image artifact en anglès

In the present study, one PET maximum intensity projection image artifact was corrected by employing the method of retro-reconstruction.

FLAIR images had more image artifacts, but the image interpretation was not influenced.

Image artifacts were analyzed and compared using Wilcoxon paired signed rank-test.

Conclusion: Image artifacts are common and can lead to incorrect interpretations of OCT angiography images.

The qualitative evaluation was performed as a multireader analysis concerning lesion detection, lesion delineation and image artifacts.

Respiratory ordered phase encoding is often employed in MRI studies to reduce image artifacts due to breathing motion.

Results: Results show that both body contour and CT numbers are altered by image artifacts in eFOV reconstruction.

Purpose: To describe image artifacts of optical coherence tomography (OCT) angiography and their underlying causative mechanisms.

The techniques were compared in image quality (vessel delineation, image artifacts, and noise) and image reconstruction error.

However, the assessment of complex blood flow patterns with conventional gradient echo flow sequences suffer from severe image artifacts.

Super-resolution microscopy depends on steps that can contribute to the formation of image artifacts, leading to misinterpretation of biological information.

Conclusion: This study demonstrates the feasibility of a wideband pulse sequence for cardiac T1 mapping without significant image artifacts induced by ICD.

Conclusions: Overall, the amplitude-binning algorithm for 4DCT reconstruction reduced the severity of tumor distortion and image artifacts compared to the phase-binning algorithm.

Those image artifacts may potentially affect the accuracy of tumor target delineation or the shape representation of surrounding nontarget tissues and organs.

Breathing-induced bulk motion of the myocardium during data acquisition may cause severe image artifacts in coronary magnetic resonance angiography (MRA).

However, image artifacts caused by cardiac motion, the ablation electrode, and radiofrequency ablation currently pose a challenge to MRI thermography in the heart.
