Summary

[edit]
Description
English: Real-time Magnetic Resonance Imaging of a child swallowing pineapple juice. Pineapple juice contains an inherent concentration of paramagnetic manganese, which serves as an MRI contrast agent for T1-weighted images.
Українська: Магнітно-резонансна томографія в реальному часі, знята під час ковтання ананасового соку дитиною. Такий сік містить певну концентрацію парамагнітного марганцю, який служить контрастною речовиною та виглядає яскравим. Фоновий шум виникає внаслідок швидкого перемикання електромагнітів, які допомагають у процесі візуалізації, зокрема, кодуючи просторову інформацію.

Media of the day This file was selected as the media of the day for 07 May 2025. It was captioned as follows:
English: Real-time Magnetic Resonance Imaging of a child swallowing pineapple juice. Such juice contains an inherent concentration of paramagnetic manganese, which serves as a contrast agent and appears bright. The background noise results from the rapid switching of electromagnets that assist in the imaging process, particularly by encoding spatial information.
