This review covers current and emerging imaging techniques for diagnosing pancreatic diseases. Advanced methods like multidetector CT and endoscopic ultrasound offer superior accuracy for pancreatic cancer staging and pancreatitis assessment.

Area of Science:

  • Radiology and Medical Imaging
  • Gastroenterology
  • Oncology

Background:

  • Pancreatic diseases, including cancer and pancreatitis, require accurate diagnosis and staging.
  • Current imaging modalities have limitations in fully characterizing pancreatic lesions and disease severity.

Purpose of the Study:

  • To review current imaging modalities for pancreatic diseases.
  • To discuss the future role of emerging technologies in pancreatic disease management.

Main Methods:

  • Review of current literature on imaging techniques for pancreatic adenocarcinoma, acute pancreatitis, and chronic pancreatitis.
  • Discussion of multidetector row spiral computed tomography (MDCT), positron emission tomography (PET), echo-enhanced ultrasound (EUS), endoscopic ultrasound with fine needle aspiration (EUS-FNA), computed tomography severity index (CTSI), endoscopic retrograde cholangiopancreatography (ERCP), magnetic resonance cholangiopancreatography (MRCP), and secretin-stimulated imaging.

Main Results:

  • MDCT is superior to conventional CT for pancreatic adenocarcinoma detection and staging.
  • PET-CT fusion may enhance pancreatic cancer staging accuracy.
  • EUS-FNA is highly accurate for diagnosing and staging nonmetastatic pancreatic cancer.
  • Modified CTSI correlates better with outcomes in acute pancreatitis.
  • ERCP remains the gold standard for chronic pancreatitis morphology, with MRCP as a noninvasive alternative.
  • EUS can detect early chronic pancreatitis.
  • Secretin-stimulated imaging may assess exocrine function noninvasively.

Conclusions:

  • Advanced imaging techniques significantly improve the diagnosis, staging, and management of pancreatic diseases.
  • Emerging technologies hold promise for more accurate and less invasive pancreatic disease assessment.
