Ultra-low dose CT safely diagnoses pneumonia in patients

A new study shows that denoised ultra-low dose CT scans can safely diagnose pneumonia in immunocompromised patients using only 2% of the radiation of standard CT scans. This method reduces radiation exposure while maintaining diagnostic accuracy. The study involved 54 patients who underwent both standard and ultra-low dose CT scans. A deep learning algorithm improved the image quality of the ultra-low dose scans, making it easier to identify nodules and reducing false positives. Researchers believe this technique could benefit other patient groups, such as young patients. Future studies with larger samples are planned to further validate these findings.
