A ground-truth region of interest made by an expert radiologist. A mark includes the region of interest and descriptions characterising the lesion.

Note that boolean attributes default to None, rather than False, to reduce misinterpretation when the source attribute has not been set by the Radiologist. Interpret as ‘no value’.

Parameters

• id (str) – An identifier for the annotation

• lesion_id (str) – An identifier for the lesion associated with this mark; unique within episode only. Corresponds to the LinkedNBSSLesionNumber field of the ImageDB JSON, which itself maps to the key of the lesion referenced by the NBSS JSON.

• boundingBox (BoundingBox) – 2D coordinates defining the lower-left (x1, y1) and upper-right (x2, y2) corners of the mark

• conspicuity (Conspicuity) – Enumeration indicating mark conspicuity

• architectural_distortion (Optional[bool]) – The mark highlights architectural distortion

• dystrophic_calcification (Optional[bool]) – The mark highlights dystrophic calcification

• fat_necrosis (Optional[bool]) – The mark highlights an area of fat necrosis

• focal_asymmetry (Optional[bool]) – Indicates focal asymmetry

• mass (Optional[bool]) – The marked lesion is a mass

• suspicious_calcifications (Optional[bool]) – Indicates a suspicious calcification cluster

• milk_of_calcium (Optional[bool]) – The mark highlights milk of calcium mammographic features

• other_benign_cluster (Optional[bool]) – The mark surrounds a benign calcification cluster not described by other parameters

• plasma_cell_mastitis (Optional[bool]) – The marked area indicates plasma-cell-mastitis

• benign_skin_feature (Optional[bool]) – The mark captures a benign skin lesion, calcified or other

• calcifications (Optional[bool]) – The marked area has calcifications

• suture_calcification (Optional[bool]) – The marked area indicates suture calcifications

• vascular_feature (Optional[bool]) – The marked area indicates vascular calcifications

• benign_classification (Optional[BenignClassification]) – Enumeration describing the benign feature

• mass_classification (Optional[MassClassification]) – Enumeration describing the mass border
