Ultrasound
Can ultrasound benefit from the rest of radiology?
In part II of his two-part series on improving the clinical practice of ultrasound, Dr. Lars Thorelius from University Hospital in Linköping, Sweden, describes how his department has applied a radiological attitude and workflow to the modality, involving standardized scanning and full documentation, and the positive effects that have resulted.

Ultrasound -- with liberty and justice for whom?
AuntMinnie.com presents a critique of ultrasound in clinical practice by Dr. Lars Thorelius, a radiologist at Linköping University Hospital in Sweden. Thorelius charges that ultrasound's increasingly minor role is a result of poor management and training, rather than any shortcomings in the modality.

What prompts radiology department cancellations of imaging orders?
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).

Imaging linked to blood cancers in children and adolescents
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).
