Radiologist pays $7 million to settle federal fraud claims
A Florida radiologist has paid the U.S. government $7 million to settle allegations of healthcare fraud. The U.S. had charged the radiologist with defrauding federal healthcare programs by billing for CT scans that were never performed, paying other physicians for patient referrals, and ordering imaging exams that were medically unnecessary.

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.

Could AI scoring help with managing 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.

Ga-68 FZ-NR-1 PET/CT images and F-18 FDG PET/CT and PET/MRI images in representative nectin-4-positive TNBC patients. (A) PET/CT images and nectin-4 immunohistochemistry (IHC) staining of patient 1. Maximum-intensity projection (MIP) images and axial and coronal PET/CT images of Ga-68 FZ-NR-1 and F-18 FDG both showed high uptake in lung metastases (arrow). (B) PET/CT images and nectin-4 IHC staining of patient 2. MIP images and axial and coronal PET/CT images of Ga-68 FZ-NR-1 showed high uptake in recurrence of right breast cancer after surgery (arrow), and those of F-18 FDG PET/MRI showed high uptake.
