Description
This specialized radiology pipeline can;
-
extract radiology related entities,
-
assign assertion status to the extracted entities,
-
establish relations between the extracted entities from the clinical documents.
In this pipeline, five NER, one assertion and one relation extraction model were used to achive those tasks.
-
Clinical Entity Labels:
Imaging_Test,Imaging_Technique,ImagingFindings,OtherFindings,BodyPart,Direction,Test,Symptom,Disease_Syndrome_Disorder,Medical_Device,Procedure,Measurements,Units,Gender,Metastasis,Invasion,Route,Treatment,Drug,Form,Frequency,Dosage,Date,Test_Result -
Assertion Status Labels:
Confirmed,Suspected,Negative -
Relation Extraction Labels:
is_related,not_related
How to use
from sparknlp.pretrained import PretrainedPipeline
ner_pipeline = PretrainedPipeline("explain_clinical_doc_radiology", "en", "clinical/models")
result = ner_pipeline.annotate("""Bilateral breast ultrasound was subsequently performed, which demonstrated an ovoid mass measuring approximately 0.5 x 0.5 x 0.4 cm in diameter
located within the anteromedial aspect of the left shoulder. This mass demonstrates isoechoic echotexture to the adjacent muscle, with no evidence of internal color flow.
This may represent benign fibrous tissue or a lipoma.""")
