Rads urged to standardize reporting of vertebral fractures
Imaging can play a critical role in identifying patients who could benefit from pharmaceutical treatments for osteoporosis. Unfortunately, almost half of vertebral fractures go undiagnosed, even though they're visible on radiographs. The authors of a recently published review in the AJR advocate adopting a standardized approach toward fracture reporting to address this issue.

An example of a typical BgRT plan: A) PET scan on diagnostic PET/CT and B) X1 PET-Linac for patient #15 with a PET avid rib metastasis with GTV size= 3.1 cc, PTV = GTV + 5mm, BTZ (biological tracking zone) = PTV + 5 mm, AC = 14.33 kBq/mL and NTS = 21.04. Red, magenta, and green contours represent GTV, PTV, and BTZ. C) Dose distribution and D) bounded-DVH of a BgRT plan are displayed for the same patient. The bounded Dose-Volume Histogram (DVH) models variations in BgRT delivery, encompassing fluctuation in target background signal variation, target localization and dose delivery uncertainties.

AI model detects achalasia on chest x-rays
By Will Morton
Currently, few noninvasive tests are available for diagnosing the swallowing condition.
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
By Amerigo Allegretto
An echogenic rind on breast ultrasound could spell malignancy for suspicious lesions.
September 17, 2025
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).
