pancreas

Purpose and description

Enable an AI agent to recognise a pancreas, distinguish its structural and functional states, and identify what assessment or intervention may be appropriate given the evidence and authority available.

It can be Map pancreatic regions, ducts and neighbouring structures from documented observations.; Compare serial imaging and functional evidence while preserving method and timing differences.; Identify missing evidence needed to distinguish exocrine failure, endocrine dysfunction and structural disease.; Flag documented duct obstruction, tissue compromise or other concerning findings for qualified clinical review.; Assess whether proposed sampling, drainage, resection or graft monitoring has sufficient anatomical evidence and clinical authorization..

Distinguishing features

A typical native pancreas has a head associated with the duodenum and a body and tail extending toward the spleen; location alone is insufficient for ectopic tissue or a transplant.

Pancreatic tissue combines exocrine acinar and ductal components with endocrine islets; an individual sample may not capture all components.

Pancreatic ducts carry exocrine secretions toward the duodenum, distinguishing the organ from adjacent lymph nodes, spleen and adrenal tissue.

The pancreas produces digestive secretions and endocrine hormones, whereas the gallbladder stores bile; shared drainage relationships do not make them the same organ.

A mass near the pancreas requires evidence of pancreatic origin or continuity before it is treated as part of the organ.

Scope

+ Pancreatic identity, anatomical regions, variants and remaining organ extent

+ Pancreatic ducts and their connections to digestive drainage pathways

+ Exocrine secretion and evidence of effective digestive enzyme delivery

+ Endocrine tissue function and evidence of pancreatic hormone secretion

+ Local tissue changes, lesions and pancreatic complications

+ Pancreas-specific assessment, preservation and intervention constraints

- Whole-person diagnosis, treatment planning and consent

- Systemic glucose regulation and diabetes management beyond pancreatic contribution

- Liver, gallbladder and extra-pancreatic biliary tract structure and disease

- Duodenal and intestinal function beyond their interface with pancreatic drainage

- Detailed classification and staging of pancreatic tumours as disease entities

- Procedural equipment, surgical technique and transplant allocation systems

Characteristics

Host and organ context

Host organism; native organ, graft, remnant or isolated specimen Connects observations to the correct organ and determines which anatomical and functional expectations apply.

Anatomical extent

Head, uncinate process, neck, body and tail present, absent, altered or uncertain Distinguishes a complete organ from congenital variation, resection or incomplete observation.

Regional dimensions

Millimetres or millilitres, with region, imaging method and observation date Supports comparison over time without assuming one universal normal size.

Duct configuration and patency

Observed duct course and connections; patent, narrowed, obstructed, disrupted or uncertain; diameter in millimetres Determines whether pancreatic secretions have an intact drainage route.

Exocrine capacity

Preserved, impaired, unassessed or indeterminate, with supporting test and context Separates digestive secretory capacity from appearance and endocrine function.

Endocrine secretory capacity

Evidence of preserved, reduced or inappropriate secretion, or indeterminate status, by hormone and test context Avoids treating a systemic glucose result as a direct measurement of the entire pancreas.

Parenchymal condition

Observed oedema, atrophy, fibrosis, fatty replacement, calcification, necrosis or no detected abnormality Records tissue changes that may affect function, viability or intervention.

Focal abnormality

Linked lesion with region, size, solid or cystic appearance, duct relationship and evidential status Locates abnormalities without making an imaging description equivalent to a confirmed diagnosis.

Perfusion and vascular relationships

Observed perfusion and relationships to named vessels; preserved, compromised or uncertain Supports assessment of tissue viability and constraints on sampling or intervention.
