Canadians study changing approaches to suspected acute appendicitis
Sunday, November 27 | 12:05 p.m.-12:15 p.m. | SSA06-09 | Room N226As imaging for suspected appendicitis continues to evolve, researchers in Ontario, Canada, sent questionnaires to centers across the country to find out how they were handling these patients. Among the findings: Ultrasound is often the first choice for diagnosing younger patients.

FFR-CT is formidable in reducing unnecessary invasive angiography
Sunday, November 27 | 11:15 a.m.-11:25 a.m. | SSA04-04 | Room S504ABBelgian radiologists tested noninvasive fractional flow reserve CT (FFR-CT) to find out if it really reduced unnecessary invasive angiographies in chest pain patients undergoing coronary CT angiography. Their answer was yes, emphatically.

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.

December 9, 2025
Scans in a 73-year-old man with biochemically recurrent prostate cancer (prostate-specific antigen level of 0.5 ng/mL) who underwent PET/CT with 9.4 mCi of F-18 piflufolastat and a second PET/CT examination with 8.1 mCi of copper 61-NODAGA (1,4,7-triazacyclononane,1-glutaric acid-4,7-acetic acid)–prostate-specific membrane antigen for imaging and therapy (Cu-61 PSMA I&T) 24 days apart, with no intervening therapy. Maximum intensity projection (MIP) images obtained (A) 1 hour after F-18 piflufolastat administration and (B) 1, (C) 2, and (D) 4 hours after Cu-61 PSMA I&T administration are shown. Physiologic uptake is seen in the lacrimal glands, salivary glands, liver, spleen, kidneys, ureters, and bladder. Pathologic uptake in pelvic nodal metastases is labeled with arrows. The F-18 piflufolastat PET/CT MIP image reveals two avid pelvic nodal metastases (arrows). Cu-61 PSMA I&T PET/CT scans demonstrate three avid pelvic nodal metastases on 1-hour and 2-hour images (arrows); five avid pelvic nodal metastases were suspected on the 4-hour image (arrows).
