How to record head of CT scan data into OMOP CDM?

[Vines (Wang Man)]

Hi,everyone,I’ve got a problem about how to store description of head CT and report of head CT into OMOP CDM.
1.For description of head CT,we’ve got for example:“Small patchy low-density shadows were observed in Prefrontal lobe and Anterior and posterior angles of bilateral lateral ventricles”.I could not find a suitable Concept id in the OMOP CDM.
2.For report of head CT into OMOP CDM,we’ve got for example:“demyelinating Changes in white matter”、“Mild cerebral atrophy in the left frontal lobe”.I could not find a suitable Concept id in the OMOP CDM too.
So my question is:Is there any Concept id for this kind of data?How can I find it? If not,how could I record them?
Thank you guys in advance.

As we nlped the report of Head CT scan,we’ve got three types of entities:“Orientation(Left,right,bilateral etc.)”、“Anatomical site(parietal lobes,occipital lobes,thalamus etc.)” and “Changes(Atrophy,infarction,widen etc.)”.
If I could find all of the entities’ Concept ID,then how can I store them,which means which field should I give them respectively?
However,if I could not find corresponding Concept ID,then how can I store them into OMOP CDM?

How can i store the discription and report of Head CT scan into CDM?

We have two kinds of data about Head CT scan: discription and report.Discription is about some changes in the brain, like" Low-density shadow in frontal lobe. the fourth ventricle enlarged". Report is about what kind of disease in the brain like “Maxillary sinusitis”、“Lacunar cerebral infarction in right basal ganglia”.We have already NLP the raw data into different entity like “orientation”、“position”、“visible”、“invisible”、“changes”、“the measure of changed area”、“CT value”. 1.Where should i s…

@Vines

Mild cerebral atrophy in the left frontal lobe

has 3 axes described above: Orientation , Anatomical site, Changes.
That can be fit into some Imaging extension table, seems it is exactly what @SCYou is working on.

Because I am wondering if anybody else have better idea.

Yea,you are right.But I have no idea how the things are going so far.
