Abstract:
Carcinoid is a subtype of neuroendocrine tumor, a rare group of tumors that are known to express somatostatin receptor 2. Ga-DOTATATE is a somatostatin analog that is specific for somatostatin receptor 2 and therefore allows visualization of neuroendocrine tumors. We present 2 cases of primary multifocal small bowel carcinoid evaluated using Ga-DOTATATE PET/CT, along with contrast-enhanced CT corollary findings. Given the increased sensitivity of Ga-DOTATATE PET/CT compared with CT and In-octreotide scintigraphy, we expect multifocal carcinoid to become increasingly recognized.

Irritable Bowel Syndrome (IBS) is classified into subtypes based on the predominant bowel habits as determined by the Bristol Stool Form Scale (BSFS). The subtypes are:
01:17Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
