    Radiologist here. 👋🏻

    You are right it does not require contrast. The scan uses a special technique to reduce signal from tissue that isn’t moving so only things that are moving produce high signal and show up “bright.” Since blood is the only thing really moving in the brain - voila!






  • I have no evidence of this theory but I suspect that it is partly a result of careful manipulation.

    Many buttons/menus in iOS utilize the blue color for text or backgrounds that also is used when you message another iOS device. The result is that it feels congruent and natural within the color scheme of the operating system - if you are messaging an Apple device.

    The green color used for messages to non Apple devices is somewhat jarring in comparison and subtly (or subconsciously) gives you the impression that something is not right. Additionally the green that was chosen provides less contrast to the white text (relative to the darker blue & white). So reading the green bubbles is just a little more effort. These effects combine to a general sense of unpleasantness.

    I believe all of this is deliberate on Apple’s part and isn’t as simple as someone “caring” about colors but rather the situation being engineered to make them care.
