Dear Digital X-Ray Insider,
More is always better, especially when it has to do with pixels, right?
That might not be the case with computed radiography (CR), at least according to a new study we're featuring this week as our Insider Exclusive. In the article, Korean researchers compare the performance of high-resolution computed radiography with conventional standard-resolution CR in a clinical environment.
The group's goal was to see whether the better technical specifications of high-resolution CR -- in particular a 4K image matrix and 100-micron pixel size -- resulted in better diagnostic accuracy for radiologists reading chest images. They had a panel of four radiologists read a series of studies that had been acquired with CR in both 4K and conventional 2K modes, and assessed their results based on three types of commonly encountered chest pathology.
We don't want to give away the ending, but suffice it to say you shouldn't feel bad if you're not routinely running your CR unit in high-resolution mode. Get the rest of the details by clicking here.

(A, B) Paired anteroposterior (AP) chest radiograph and dual-energy x-ray absorptiometry (DXA) report shows lumbar spine (L1 through L4) areal bone mineral density (BMD). The DXA report was reformatted for anonymization and improved readability. The patient had low BMD (Z score ≤ −2.0). (C) Model (chest radiography [CXR]–BMD) output shows the predicted raw BMD and Z score in comparison with the DXA reference standard, together with interpretability analyses using Shapley additive explanations (SHAP) and gradient-weighted class activation maps. The patient was classified as having low BMD, consistent with the reference standard.
