Scum can also easily remember MRI signal changes for cerebral hemorrhage!
For neurologists, mentioning changes in MRI signals for cerebral hemorrhages is a really bald problem.
As we all know, there are 5 stages of cerebral hemorrhage, and different stages are manifested in the signals on mri's T1WI and T2WI, one moment is T1 low signal T2 high signal, one moment is T1 high signal T2 low signal, one moment both are high, one moment both are low... It's completely confusing!!!
At this time, neurologists who are often the masters of learning will come out and explain:
"If you understand, you remember!"
"Because the hyperacute phase is intracellular oxygenation of hemoglobin, so T1 is low signal, T2 is high signal!"
"The acute phase becomes deoxyhemoglobin, so T2 becomes a low signal!"
Best......
However, as scum, we just want to know how to remember such a complicated thing!
In order to solve this need, scum representatives around the world have balded themselves and tried their best to help us who are also scum to remember this important point.
For example, make a table:
Another example, draw a diagram:
Even, do a poem:
“
I Bleed
I The
Bleed Die
Bleed Bleed
The
”
Among them, I is the intermediate signal, B is the high signal (Bright), D is the low signal (Dark), and a poem represents the MRI signal change in different periods.
However, many scum said: also! be! remember! No! live! yes!
Don't worry, today's play is coming, just one gesture is needed to easily remember the MRI signal changes during the 5 periods of cerebral hemorrhage:
What does this mean?
Don't worry, make this gesture with your hands first. Starting from the little finger, count the thumbs, representing 5 periods of cerebral hemorrhage:
Little Finger—Ultraacute Phase
Ring finger - acute phase
Middle finger – early subacute phase
Index finger - late subacute phase
Thumb – chronic phase
An outstretched finger indicates a high signal, and a curled finger indicates a low signal or equal signal. The left hand represents the T1 signal and the right hand represents the T2 signal. Looking at it this way, it is not clear at a glance
For example, the hyperacute phase, the first period, look at the little thumb:
The little thumb of the left hand is curled up, and the little thumb of the right hand is spread, which means that the left T1 signal is a low signal or equal signal, and the right hand T2 signal is a high signal.
Looking at the acute phase, which is the second period, look at the ring finger:
The ring fingers of both hands are curled up, which means that both the T1 and T2 signals are low signals.
Early subacute, the 3rd period, look at the middle finger:
The middle finger of the left hand is extended and the right finger is curled up, which means that the left T1 signal is a high signal and the right hand T2 signal is a low signal.
In the late subacute phase, the 4th period, look at the index finger:
The index fingers of both hands are extended, which means that both the T1 and T2 signals are high signals.
Finally, the chronic phase, the 5th period, look at the thumb:
Both thumbs are curled up,
This means that both T1 and T2 signals are low signals.
How, isn't it simple?
what? Can't remember the gestures?
Come and go, the left hand is the scissor hand of "Yah":
The right hand is the rocker of "Medicine Chek":
Or it can also be understood as the orchid of Guanyin Niangniang:
How, such an analysis,
Isn't it much easier to remember?
Of course, if you have a better way,
Welcome to leave us a message and share it with the scum of the crowd.
Everyone hugged together and went to the peak of life!
