AI detects incidental lung nodules on chest x-rays
By Will Morton
AI based lesion-detection software used in daily practice can help identify clinically significant incidental lung nodules on chest x-rays
November 16, 2023
A true positive case in a 72-year-old male with a granuloma on chest x-ray after visiting the neurology outpatient clinic for memory disturbance. A small lung nodule was detected in the left-middle to lower lung field by AI software, with an abnormality score of 26%. Co-existing fibrosis was suspected in the apex of bilateral upper lungs, with an abnormality score of 76%. Image courtesy of Scientific Reports.

NIH highlights PET study in Parkinson’s disease
By Will Morton
The NIH has highlighted a study that shows cardiac PET scans can help identify people at risk for Parkinson’s disease.
November 9, 2023
Heart and brain PET scans from a study participant who developed Parkinson’s disease support a “body first” progression. The top pair of PET scan images show low F-18 dopamine-derived radioactivity in the heart (right, with N-13 ammonia PET scan on left). Later, brain scans showed a loss of dopamine-producing neurons and the individual developed symptoms of the disease. Image courtesy of the National Institutes of Health.
