Study finds clinical niche for DR tomo in pulmonary lesions
Imaging researchers have long known that chest tomosynthesis is more sensitive than conventional x-ray for detecting malignant pulmonary lesions, while producing lower radiation dose than CT. Now, they are zeroing in on a precise role for this unique technology.

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.
