Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.

(A) F-18 AlF-NOTA-BCP137 PET/CT images before and after immunotherapy for patient 1 and patient 2. (B) F-18 AlF-NOTA-BCP137 PET/CT and MR images of patient 3 (left panels) after one cycle of immunotherapy. PET images showed higher uptake by tumor and spleen, and PET result was evaluated as positive; therefore, the patient was considered to be responder to treatment and underwent surgical resection. Representative images of hematoxylin and eosin (HE) staining and multiplex immunofluorescence of CD8 and CD137 (right panels) in HCC tumor and adjacent normal tissues of patient 3 after surgery. Nuclei were stained with 4′,6-diamidino-2-phenylindole. Primary tumors are indicated by white arrows, and increased thyroid uptake is indicated by red arrow in PET images.
