Stone countertop workers at risk of silicosis

CT imaging shows that engineered stone countertop workers are at risk of developing the lung disease silicosis.

December 2, 2024

Contrast-enhanced chest CT shows upper predominant fibrosis/lung scarring (red oval), solid masses adjacent to a left-sided pneumothorax (yellow oval) and diffuse silicotic nodules (purple circle). This patient had a history of working in the countertop-cutting industry (15 years), smoking cigarettes (10 pack years), and active tuberculosis (treated 7 years prior and excluded at the time of this image with laboratory testing).

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.

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).

Radiologists can designate nonmass lesions on breast ultrasound

By Amerigo Allegretto

Breast radiologists achieved moderate to substantial interreader agreement for classifying nonmass lesions on ultrasound.

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.
