Embodiment 1
[0040] A contrast agent for magnetic resonance cholangiopancreatography, which is tea water with a manganese concentration of 5 mg / L.
[0041] The production method is as follows: pour 200ml of boiled water into a beaker containing 4g of Pu'er tea, shake it intermittently for 5 times, and after about 30 minutes, add the upper layer solution, which is tea.
[0042] Instructions: After 12 hours of fasting, the subjects took 200ml of the above-mentioned tea orally, at a rate of about 200ml / min, and checked after about 20 minutes.
[0043] The outline of pancreaticobiliary duct after MRCP scanning is more clearly delineated than conventional MRCP.
Embodiment 2
[0045] A contrast agent for magnetic resonance cholangiopancreatography, which is tea water with a manganese concentration of 12.04±0.2mg / L.
[0046] The production method is as follows: pour 300ml of boiled water into a beaker filled with 10g of Rizhao green tea, shake it intermittently for 3 times, and after about 20 minutes, add the upper solution, that is, tea.
[0047] Instructions: After 12 hours of fasting, the subject takes orally 300ml of the above-mentioned tea at a speed of about 300ml / min, and checks after about 10 minutes.
[0048] After MRCP scanning, the image is very clear Figure 4 .
Embodiment 3
[0050] A contrast agent for magnetic resonance cholangiopancreatography, which is tea water with a manganese concentration of 13 mg / L.
[0051] The production method is as follows: pour 400ml of boiled water into a beaker containing 16g of rose tea, shake it intermittently for 3 times, and after about 20 minutes, add the upper layer solution, which is tea.
[0052] Instructions: After 12 hours of fasting, the subject takes orally 400ml of the above-mentioned tea at a rate of about 300ml / min, and checks after about 10 minutes.
[0053] The image after MRCP scan is very clear.
