Summary
Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) require advanced imaging. Dual-phase CT/MR and PET-CT are crucial for accurate detection, staging, and monitoring of these rare neoplasms.
Area of Science:
- Oncology
- Radiology
- Medical Imaging
Context:
- Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare and heterogeneous neoplasms, accounting for only 2% of gastrointestinal tumors.
- A variety of diagnostic imaging modalities are available for GEP-NETs, including ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography CT (PET-CT).
Purpose:
- To review the role and performance of various diagnostic imaging modalities in the detection, staging, and treatment monitoring of GEP-NETs.
- To highlight the strengths and weaknesses of different imaging techniques based on tumor location and type.
Summary:
- CT and MR enteroclysis show high sensitivity and specificity for detecting small bowel NETs.
- MRI demonstrates superior sensitivity for pancreatic NETs compared to CT.
- PET-CT is highly sensitive for detecting small primary tumors, while MRI excels in identifying liver metastases.
Impact:
- Diagnostic imaging is essential for precise tumor localization, metastasis identification, therapy planning, and treatment response evaluation.
- The selection of the optimal imaging modality depends on the specific characteristics of the GEP-NET.
- Dual-phase CT/MR imaging and whole-body staging with CT and PET-CT are recommended for comprehensive management of GEP-NETs.

813
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...

01:24Chronic Pancreatitis I: Introduction
897
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

The pancreas, a vital organ within the abdominal cavity, plays dual roles in the digestive and endocrine systems, collaborating with exocrine and endocrine cells to maintain optimal digestion and blood sugar levels.
Exocrine function is carried out by acinar cells, organized into clusters known as acini. These cells contribute to digestion by releasing substantial quantities of enzyme-rich, alkaline digestive juices.
Concurrently, the dispersed clusters of endocrine cells throughout the...

Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
