Recently, the data of lymph node ultrasound were collected and analyzed, and the size of a single lymph node was judged by the distribution of lymph node size in the population.
Neck, axillary, and inguinal lymph nodes were analysed separately. None of these lymph nodes are tumours. I'll write them separately.
Ninety cervical lymph nodes were collected, obeying a normal distribution with an average long axis of 1792 millimeters (mm) with a standard deviation of 595mm, so that the mean plus 2 times the standard deviation: 1792+5.95x2=29.82mm。
Then according to statistical judgment, if the long axis of your neck lymph node is greater than 29At 82mm, the long axis of your neck lymph nodes is considered large.
This means that at this point your lymph nodes have a long-axis ratio of 975% of people are big.
Then say the short axis: the average length 671mm, standard deviation 212mm，6.71+2.12x2=10.95mm。
The short axis of the cervical lymph node if greater than 10At 95mm, it's big.
Approximately, if your neck lymph nodes are 30x11mm, your lymph nodes are statistically large.
than 975 And all of them shall have great lymph nodes.
At this time, you should pay attention to see if it is inflammation or other causes.
d'The Agostino & Pearson Test obeys a normal distribution.
If only one axis is considered large and the other axis is not large, it does not meet my analysis criteria here.
You need to analyze the specific problem on a case-by-case basis, or you need to consult a doctor.
In addition, my analysis method is only based on the size of the lymph node, and does not include other conditions such as the cortical medulla, border, and blood flow signal of the lymph node, and cannot be used to accurately judge the quality of the lymph node.
It's just a simple but crude way to judge.
It's a bit of a science, but it's not much, it's very rough, so it's just for reference.
In the end, it is still the same sentence: I wish everyone good health, and I wish the world no disease!
The results of the analysis of both axillary and inguinal lymph nodes are pasted below.
61 axillary lymph nodes, long axis: 1968+6.46x2=32.6mm；Minor axis 683+2.60x2=12.03mm。
That is to say the armpit here: lymph nodes 326x12.03mm is considered large.
36 inguinal lymph nodes, long axis: 2000+6.79x2=33.58mm；Minor axis 522+1.62x2=8.46mm。
That is to say the groin here: lymph nodes 3358x8.It's big at 46mm.
