Training technique in AI helps preserve patient privacy
By Will Morton
The privacy of patient data in AI models trained on chest x-rays can be guaranteed – importantly, without significantly reducing the accuracy of models on large “real-world” data sets.

FAPI-PET/CT outperforms FDG-PET/CT in women with invasive breast cancer
By Will Morton
PET/CT imaging using gallium-68 FAPI radiotracer over F-18 FDG appears promising in women with invasive lobular carcinoma.

Maximum-intensity projection F-18 FDG-PET (left) and Ga-68 FAPI-PET (right) images of synchronous ILC. (A) A 42-year-old patient with multicentric primary lesions (encircled), regional (solid arrows), and distant inferior jugular lymph node (dashed arrows) seen on F-18 FDG-PET and subsequently confirmed on Ga-68 FAPI-PET, which also revealed additional malignant foci aligned with MRI. Some lesions exhibited high activity retention on Ga-68 FAPI-PET. (B) A 53-year-old patient showing no significant uptake on F-18 FDG-PET but synchronous bilateral lesions (arrows) on Ga-68 FAPI-PET, which also identified pathologic lymph nodes (encircled), resulting in upstaging.

Imaging surveillance suggested for radial scars found on DBT
By Amerigo Allegretto
Imaging surveillance may be the way to go for tracking radial scars without atypia found on screening DBT.
March 14, 2024
Images taken from a 40-year-old woman with calcifications detected on baseline screening mammography show (A) lateral and (B) craniocaudal magnification views for grouped pleomorphic calcifications in right breast (circles). Stereotac-tic-guided core-needle biopsy yielded radial scar without atypia. Subsequent surgical resection yielded radial scar (i.e., not upstaged). Image courtesy of ARRS.
Coronary angiography matches IVUS in guiding PCI stent implantation

AI flags rare humeral bone tumors on chest x-rays
By Will Morton
An AI algorithm can help identify rare tumors on upper arm bones in patients undergoing chest x-rays – findings not typically identified in daily reading practice.
March 13, 2024
The tumor localization/visualization results obtained by the proposed AI algorithm. Original chest x-ray images with a lesion (red circle = radiologists’ annotation of the lesion location) and AI's lesion localization result. These examples demonstrate that the proposed technique can successfully detect humeral tumors. Image and caption courtesy of Radiology: Artificial Intelligence.
