Vaping case study offers guidance for radiologists
The case study of a 24-year-old man with lung damage from vaping provides hints to radiologists on what to look for in patients who present with characteristic symptoms and a history of electronic cigarette use, according to a special report published October 31 in Radiology: Cardiothoracic Imaging.

New MRI contrast material promises earlier liver diagnosis
A new gadolinium-based contrast material could form the basis for submillimeter detection of tumors on MRI scans and provide a warning of early-stage liver disease sooner than conventional MRI contrast agents, according to findings from an animal study released October 29 in Nature Communications.

'Light' cigarettes don't reduce lung cancer mortality
If you're a smoker and want to cut your chances of dying from cancer by smoking a "light" brand of cigarette, think again. Researchers found no difference in lung cancer mortality between those who smoked light cigarettes and those who puffed regular smokes, according to a study published on October 21 in JAMA Internal Medicine.

Do CT lung screening rules overlook first responders?
Current guidelines covering who is eligible for CT lung cancer screening do not take into account the hazards encountered by occupational exposure to environmental toxins, such as those encountered by first responders. That's according to research presented October 11 at the North American Conference on Lung Cancer in Chicago.

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.

September 18, 2025
Saliency maps using Grad-CAM++ (E and H) show the model’s point of interest in chest radiographs (C and F) of patients with achalasia. The model’s point of interest is highlighted with red, yellow, and green. In both the upper and lower panels (E and H), the point of interest is located in a region around the upper esophagus that corresponds to an air esophagogram and/or air-fluid level in the esophagus in the barium esophagogram (D and G).

Echogenic rind on breast ultrasound holds diagnostic significance

Diagnostic transverse ultrasound image of the left breast in a 64-year-old woman shows irregular hypoechoic nonparallel mass with indistinct margins corresponding to palpable finding, assessed as BI-RADS category 4. Both readers assessed mass as having associated echogenic rind with complete circumferential extent (arrowheads). Ultrasound-guided biopsy of mass yielded diagnosis of invasive ductal carcinoma (intermediate grade, luminal A molecular subtype, no lymphovascular invasion).
