Background: Dark-field radiography has been proven to be a promising tool for the assessment of various lung diseases.
Purpose: To evaluate the potential of dose reduction in dark-field chest radiography for the detection of the Coronavirus SARS-CoV-2 (COVID-19) pneumonia.
Materials And Methods: Patients aged at least 18 years with a medically indicated chest computed tomography scan (CT scan) were screened for participation in a prospective study between October 2018 and December 2020.
Artificial Intelligence (AI) is an emerging tool that could be leveraged to identify the effective conservation solutions demanded by the urgent biodiversity crisis. We present the results of our horizon scan of AI applications likely to significantly benefit biological conservation. An international panel of conservation scientists and AI experts identified 21 key ideas.

We explored the potential of dark-field imaging of bone microstructure to improve the assessment of bone strength in osteoporosis.
Methods: We prospectively examined 14 osteoporotic/osteopenic and 21 non-osteoporotic/osteopenic human cadaveric vertebrae (L2-L4) with a clinical dark-field radiography system, micro-computed tomography (CT), and spectral CT.
Purpose: Dysphagia is the inability or difficulty to swallow normally. Standard procedures for diagnosing the exact disease are, among others, X-ray videofluoroscopy, manometry and impedance examinations, usually performed consecutively. In order to gain more insights, ongoing research is aiming to collect these different modalities at the same time, with the goal to present them in a joint visualization.

- The study compares the effectiveness of 0.55 T MRI scanners to traditional 3.0 T MRIs in reducing metal artifacts around orthopedic implants.
- Results showed that metal artifacts were significantly smaller with the 0.55 T MRI, especially using the SEMAC sequence, and that it provided better visualization of anatomical structures.
- The authors conclude that the 0.55 T MRI offers substantial advantages, but further clinical research is needed to confirm its benefits for patients.
