A recent inquiry of whether a lumbar puncture can cause meningeal enhancement led us to the paper, “Frequency of Unexplained Meningeal Enhancement in the Brain After Lumbar Puncture,” by Mittl and Yousem (1). The conclusion that intracranial dural-arachnoidal enhancement after lumbar puncture is uncommon is not supported by the data that are presented. In their prospective study, they claim the...

We introduce EnhanceGAN, an adversarial learning based model that performs automatic image enhancement. Traditional image enhancement frameworks involve training separate models for automatic cropping or color enhancement in a fully-supervised manner, which requires expensive annotations in the form of image pairs. In contrast to these approaches, our proposed EnhanceGAN only requires weak supe...
