RESUMO
Medical imaging analysis depends on the reproducibility of complex computation. Linux containers enable the abstraction, installation, and configuration of environments so that software can be both distributed in self-contained images and used repeatably by tool consumers. While several initiatives in neuroimaging have adopted approaches for creating and sharing more reliable scientific methods and findings, Linux containers are not yet mainstream in clinical settings. We explore related technologies and their efficacy in this setting, highlight important shortcomings, demonstrate a simple use-case, and endorse the use of Linux containers for medical image analysis.

Valsalva retinopathy can present as a sudden, dramatic loss of central vision due to the premacular location of the resultant subhyaloid hemorrhage. Certain vascular conditions predispose to the condition and occasional reports exist of Valsalva retinopathy in pregnancy. The authors describe a case of Valsalva retinopathy in a pregnant patient in terms of the physical features present that led to making the decision to treat by Nd:YAG laser hyaloidotomy as opposed to conservative management. Spectral-domain optical coherence tomography (SD-OCT) was able to demonstrate the physical features of the lesion prior to, immediately after, and weeks after treatment, and showed not only the dispersion of hemorrhage into the vitreous cavity from the subhyaloid space, but also that the subhyaloid cavity dimensions were unchanged despite release of the hemorrhage. SD-OCT visualized the actual hyaloidotomy site and its subsequent closure, which has not previously been reported in the literature.

Human mirror mechanisms (MMs) respond during both performed and observed action and appear to underlie action goal recognition. We introduce a behavioral procedure for discovering and clarifying functional MM properties: blindfolded participants repeatedly move beans either toward or away from themselves to induce motor adaptation. Then, the bias for perceiving direction of ambiguous visual movement in depth is measured. Bias is affected by (a) number of beans moved, (b) movement direction, and (c) similarity of the visual stimulus to the hand used to move beans. This cross-modal adaptation pattern supports both the validity of human MMs and functionality of our testing instrument. We also discuss related work that extends the motor adaptation paradigm to investigate contributions of MMs to speech perception and language comprehension.
