Morphologic-radiographic correlations of the pancreas

Area of Science:

• Gastroenterology and Hepatology
• Diagnostic Imaging
• Oncology

Background:

• Pancreatic diseases present diagnostic challenges due to the pancreas's anatomical location and proximity to major vasculature.
• While imaging can detect pancreatic neoplasms, effective treatment remains limited.
• Vascular invasion, indicated by neoplastic infiltration, often signifies nonresectable disease.

Purpose of the Study:

• To review current imaging modalities for pancreatic disease diagnosis.
• To highlight the efficacy of specific techniques in identifying pancreatic malignancies and vascular invasion.
• To discuss the role of angiography in diagnosing islet cell tumors.

Main Methods:

• Review of noninvasive and invasive imaging techniques for pancreatic disease.
• Evaluation of needle biopsy under fluoroscopic or echographic guidance for malignancy diagnosis.
• Assessment of angiography and selective pancreatic vein catheterization with hormone bioassays for islet cell tumors.

Main Results:

• Needle biopsy is emerging as a sensitive and specific method for diagnosing pancreatic malignancy.
• Angiography demonstrates high utility in diagnosing hypervascular islet cell tumors.
• Vascular invasion, often visualized through imaging, is a critical indicator of nonresectability.

Conclusions:

• Despite advances in imaging, treatment of pancreatic cancer remains a significant challenge.
• Needle biopsy and angiography represent valuable tools for diagnosing pancreatic neoplasms, particularly islet cell tumors.
• Accurate diagnosis through advanced imaging is crucial for determining treatment strategies and patient prognosis.
