Operating beyond 3T: Is clinical use in reach?
VIENNA - The standard field strength of clinical MR units is still 1.5 tesla, but the past five years have seen a tremendous increase in the number of devices operating at 3.0 tesla. In addition, whole-body systems up to 9.4 tesla have become available in experimental settings and have already proved to be significantly beneficial in special purpose examinations.

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).

Question 4 from the Japan Diagnostic Radiology Board Examination 2024, representing a clinical scenario of a man in his 30s presented with transient dysphasia. The question asks to identify the most probable diagnosis from the following options: (a) glioblastoma, (b) hemangioblastoma, (c) metastatic brain tumor, (d) oligodendroglioma, and (e) primary central nervous system lymphoma (PCNSL). The correct answer is (d) oligodendroglioma. The figure also includes a summary of responses from four large language models, along with their legitimacy scores rated by diagnostic radiologists.
