Marathon training does not have long-term negative effects on heart

December 10, 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).

Phase I trial reveals the potential of a new PSMA-PET tracer

December 9, 2025

Images depict a 50-year-old woman with a lesion detected during screening ultrasound. (A) Transverse and (B) longitudinal images reveal a 0.5-cm hypoechoic lesion (arrow) in the left breast. (C) Transverse color Doppler ultrasound image does not show an increase in vascularity. Two readers classified the lesion as a mass, whereas two others categorized it as a nonmass lesion, leading to its designation as a controversial nonmass lesion. Ultrasound-guided core needle biopsy and subsequent pathologic examination confirmed a nonproliferative breast change.

Phase I trial reveals the potential of a new PSMA-PET tracer

The radiotracer detected more lesions in men with metastatic disease than F-18 piflufolastat.

Radiologists can designate nonmass lesions on breast ultrasound
