Great moments in TV with medical images/scanners! #12

This week, I have a great video for you. In the last episode of Modern Family, Claire goes to the hospital to make a check-up cardiac angiography. I was surprised that she stayed in a hospital bed before and after the procedure, so I googled a bit about it. Then, I come across the best angiography video ever!

The scene was considered by the director to be the most disturbing one from the whole movie and the medical team there is a real one! However, the procedure is not a real one... (and it is a cerebral angiography).

Time-of-Flight PET vs. MRA

Every time I hear Time-of-Flight TOF, I get confused because it can actually mean TOF PET or TOF MRA. The two acronyms have the some words: Time Of Flight, but have different meanings. 

TOF PET - This PET technology means that the time difference between two photons detected as a coincidence will be used to estimate the actual place of positron annihilation.

TOF MRA - This Magnetic Resonance angiography technique means that a sequence with small time of repetition TR will be used to saturate the stationary nucleus, while the flowing nucleus with Time-Of-Flight will be maximal. 

Both techniques produce beautiful images:
