Cardiac MRI scan - heart beat in real time HD (by mushin111)


A human heart stripped of muscle, fat and connective tissues. Left behind, the complexity of the innumerable blood vessels that keep our hearts beating is something to behold.

Soon you will be able to grow your own heart, with your own stem cells.

Scientists Use 3-D Printer To Help Create Prototype Next-Gen Pacemaker

"This video shows a rabbit heart that has been kept beating outside of the body in a nutrient and oxygen-rich solution. The new cardiac device — a thin, stretchable membrane imprinted with a spider-web-like network of sensors and electrodes — is custom-designed to fit over the heart and contract and expand with it as it beats."


Happy Valentine’s Day! This image of a heart was sequenced by a Revolution* CT scanner, which can take a complete 3-D scan of a heart in one beat.

A decellularized “ghost” heart.

Decellularization is a chemical process by which the cells are removed, leaving behind the extra cellular matrix (ECM) composed of connective tissue. (Eg reticular fibers, etc.) It is done so that new cells that match a transpalntees DNA can be grown on this “ghost” such that there is a 100% match with the patient so no organ rejections can happen.

Cardiac CT.

I have gotten a chance to look at a number of CT scans; I swear these images never get old.
