MIRC clusters summary

RadLex and SNOMED CT terms	Cluster summary
•Right: RadLex descriptor =⇒ location descriptor =⇒ laterality •Thorax: Anatomical entity =⇒ material anatomical entity =⇒ anatomical structure =⇒ subdivision of cardinal body part =⇒ subdivision of body proper =⇒subdivision of trunk =⇒ subdivision of trunk proper •Congenital: RadLex descriptor =⇒disease origin descriptor •Heart: Anatomical entity =⇒ material anatomical entity =⇒ anatomical structure =⇒ Organ =⇒ cavitated organ =⇒ organ with cavitated organ parts •Present: RadLex descriptor =⇒ quantity descriptor •SNOMED CT: Heart, Right, Pulmonary, Left, Age	Focusing on anatomical structures of a body. Descriptors tell us about location of body parts (right or left), origin behind diseases, possible different diseases, and patient gender. Based on anatomical structure, location of disorder, and gender of patient, radiologists discuss conditions related to congenital heart, thorax, and aorta. Most of the teaching files within cluster no. 1 are about a female child with an abnormal structure of the heart, cases with enlarged heart, or problems related to blood vessels.
•Female: RadLex descriptor =⇒ patient descriptor =⇒ gender •Normal: RadLex descriptor =⇒ normality descriptor •Femur: Anatomical entity =⇒ material anatomical entity =⇒ anatomical structure =⇒ Organ =⇒ cavitated organ =⇒ organ with cavitated organ parts =⇒ bone organ =⇒ long bone •Possibly: RadLex descriptor =⇒ certainty descriptor •Dysplasia: clinical finding =⇒ pathophysiologic finding •SNOMED CT: Abnormal, Adequate, Infant, Congenital, Dysplasia	Female patients with a possibility of having dysplasia. Anatomical entities focus on femur and tissues related to different organs. Based on clinical finding, treatment is provided under procedure category. Most of the teaching cases are related to female patient with dysplasia—an abnormal growth of tissues.
•Possibly: RadLex descriptor =⇒ certainty descriptor •Present: RadLex descriptor =⇒ quantity descriptor •Right: RadLex descriptor =⇒ location descriptor =⇒ laterality •Normal: RadLex descriptor =⇒ normality descriptor •Set of bone organs: Anatomical entity =⇒ anatomical set =⇒ set of organs =⇒ set of bone organs •SNOMED CT: Normal, Fracture, Proximal, Old, Image	Anatomical entities related to bones. Based on RadLex descriptors, the presence of abnormality in bone tissues is discussed. Treatment is typically suggested under the procedure category. Most of the cases are related to complaint about bone diseases of female patients discussed with uncertainty in diagnosis
•Treatment: procedure •Neoplasm: clinical findings =⇒ pathophysiologic findings =⇒ proliferation •Possibly: RadLex descriptor =⇒ quantity descriptor •Present: RadLex descriptor =⇒ quantity descriptor •Right: RadLex descriptor =⇒ location descriptor =⇒ laterality •SNOMED CT: Lesion, Disease, Male, Skin, Old	Growth in lesion under imaging observation category. Based on clinical finding, neoplasm and infection are observed; treatment is discussed. Most of the teaching files with female patients and diseases are related to neoplasm, abnormal growth of tissues, and infection in body parts.
•Intestine: Anatomical entity =⇒ material anatomical entity =⇒ anatomical structure =⇒ subdivision of organ system =⇒ subdivision of alimentary system =⇒ subdivision of gastrointestinal system =⇒ subdivision of gut •Possibly: RadLex descriptor =⇒ quantity descriptor •Obstruction: clinical finding =⇒ pathophysiologic findings =⇒ mechanical disorder =⇒ flow disorder •Diagnosis: property •Proximal: RadLex descriptor =⇒ location descriptor •SNOMED CT: Abdominal, Obstruction, Proximal, Old, Patient	Clinical findings show mechanical disorder in body parts. Anatomical entities are related to abdominal organs such as the intestine, colon, and abdomen. Cases with findings of obstruction are observed in the colon body part.
•Possibly: RadLex descriptor =⇒ certainty descriptor •Right: RadLex descriptor =⇒ location descriptor =⇒ laterality •Present: RadLex descriptor =⇒ quantity descriptor •Treatment: procedure •Female: RadLex descriptor =⇒ patient descriptor =⇒ gender •SNOMED CT: Right, Lesion, Female, Old, Tissue	Both diagnosis and treatment are suggested based on clinical findings which are typically neoplasm. Patient gender is typically female.
