Full-field digital screening mammograms in participants recalled by the consensus discussion after being flagged by artificial intelligence (AI) computer-aided detection (CAD) but not by either of the two radiologists. (A) Mammogram with AI CAD score of 73 for a 55-year-old woman diagnosed with grade 3 in situ cancer and T1 (9-mm) invasive cancer in the left breast and lymph node metastasis. (B) Mammogram with AI CAD score of 54 for a 49-year-old woman diagnosed with grade 2 in situ cancer and T1 (6-mm) invasive cancer in the right breast and without lymph node metastasis.

Lung Cancer

How can AI best help in LDCT lung cancer screening?

A commercially available AI-based tool appears effective as a prescreener in low-dose CT lung cancer screening.

Images of a 69-year-old man diagnosed with prostate cancer who had a history of endocrine therapy for two years. (a) The maximum intensity projection (MIP) image of F-18 FDG showed moderate radiotracer uptake in a thoracic vertebra. (e) The MIP image of Ga-68 DOTA-IBA demonstrated more lesions in the cervical vertebra and pelvis. (b) An osteoblastic lesion in the C3 vertebra right attachment (curved arrows) was negative on F-18 FDG (SUVmax = 2.0) and positive on Ga-68 DOTA-IBA (SUVmax = 8.7). (c) Another osteoblastic lesion in the T10 vertebra left side (arrowheads) was both positive on F-18 FDG (SUVmax = 5.2) and positive on Ga-68 DOTA-IBA (SUVmax = 35.0). (d) Osteoblastic lesions in bilateral ilium (dotted arrows and arrows) were negative on F-18 FDG (left: SUVmax = 1.4, right: SUVmax = 1.6) and positive on Ga-68 DOTA-IBA (left: SUVmax = 7.6, right: SUVmax = 8.7). Follow-up imaging three months later confirmed the presence of these bone metastases.

New theranostics PET tracer shows promise

Ultrasound images depict a 56-year-old man with obesity (body mass index, 42) and steatosis (MRI-PDFF, 10.4%), who underwent ultrasound attenuation coefficient (AC) measurement due to participation in the present study. The unit displays color-coded confidence map (left) and AC map (on right) in side-by-side manner. The confidence map indicates quality of acquired AC signals and is set like traffic lights: green indicates good quality acquisition, yellow indicates warning, and red indicates low quality. Areas with low quality are left blank on the AC map. The image shows multiple circular ROIs placed at depths below the liver capsule of 2, 2.5, 3, and 4 cm. All ROIs are 3.5 cm in size. The confidence map threshold is set at 20%. AC measurements (in units of dB/cm/MHz) were extracted from all ROIs (excluding voxels without assigned color on the AC map) and decrease with greater ROI depth.
