PACS data-mining technique tackles CR dose creep
Looking for a way to deal with dose creep resulting from your digital x-ray systems? If you have a PACS, the solution to the problem might be as close as your data archive, according to a group from the University of Washington in Seattle. They implemented a software application that mines data from their PACS archive to help monitor computed radiography (CR) radiation dose, cutting the dose nearly in half for some applications.

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.

Two cases of pathologically confirmed intrahepatic cholangiocarcinomas in 68-year-old male patients. In both cases (A-H, case 1; I-P, case 2), CT scans (B, F, case 1; J, N, case 2) revealed intrahepatic bile duct dilation and suspected nodular lesions. While F-18 FDG PET/CT (A, C, D, case 1; I, K, L, case 2) failed to demonstrate abnormal tracer uptake (SUVmax 3.5, TBR 1.3 in Case 1; SUVmax 2.6, TBR 1.2 in Case 2), F-18 FAPI-04 PET/CT (E, G, H, case 1; M, O, P, case 2 ) showed positive uptake in the nodular lesions (SUVmax 9.7, TBR 3.5 in Case 1; SUVmax 9.6, TBR 3.3 in Case 2).

The number of all visible structures was fewer at an ambient light of 500 lux compared to both 25 and 75 lux. In addition, structure visibility was better with a gray wall color at all ambient light levels. Paired comparison between monitors showed better structure visibility on the high specification monitor for all condition.

Representative maximum-intensity projections of five patients (patients 3, 5, 7, 10, and 11) comparing Ga-68 NYM046 and F-18 FDG. Both tracers showed specific retention in bone and lymph node metastases (patients 10 and 11). Ga-68 NYM046 PET/CT outperformed F-18 FDG PET/CT in detecting primary tumors, lung metastases, and pleural metastases (patients 3, 5, 7, and 11).
