Our cancer specialists have expertise in all types of gastrointestinal (GI) cancer, no matter how rare or complex. We offer advanced diagnostic options for catching these cancers early when they’re most treatable. As leaders in innovation and research, our GI cancer doctors bring you the most advanced treatments available today.

Our Enterography Service utilizes CT enterography to visualize the small intestine and other abdominal structures, aiding in the diagnosis and management of conditions such as Crohn's disease. We transform standard CT images into 3D models using 3D grayscale volume rendering and Maximum Intensity Projection (MIP) reconstructions. These techniques enhance the contrast between different tissue densities and structures, with grayscale for volume rendering and MIP highlighting the brightest pixels. This approach helps in clearly delineating intestinal structures and identifying pathologies.
For patients with suspected Crohn’s disease or similar conditions, our service focuses on visualization of the small bowel wall and mesentery. When abnormalities are detected, we use Curved Planar Reformation (CPR) and oblique/magnified grayscale reconstructions to provide targeted views of the affected areas. These additional views enable a focused examination, potentially assisting healthcare professionals in making more informed decisions about patient care.
Our 3D imaging service for the pancreas utilizes Volume Rendering (VR) and Curved Planar Reconstructions (CPR) to provide detailed views that may enhance diagnostic capabilities for various diseases. These images may aid in the detection of conditions such as pancreatitis and pancreatic cancer, particularly in their early, more treatable stages.
Volume Rendering highlights differences in the pancreas's soft tissue, making it possible to identify small tumors or areas of inflammation. By differentiating tissue densities, VR images help detect abnormalities that may indicate disease. Curved Planar Reconstructions, on the other hand, may be effective for examining the intricate network of vessels and ducts within the pancreas, such as the Common Bile Duct (CBD) and pancreatic duct. CPR straightens these structures on the screen, allowing for easier identification of blockages, narrowings, or other abnormalities.
Our Colon Service offers CT virtual colonoscopy, also known as CT colonography, using 3D imaging techniques to create a visual reconstruction of the colon. This service transforms 2D CT scan data into a 3D model, allowing for a non-invasive virtual fly-through examination of the colon's interior. This 3D visualization may be useful for the detection of polyps, tumors, or other abnormalities, providing a thorough assessment of the colon's health with greater accuracy and detail than traditional methods.
CT virtual colonoscopy serves as a less invasive alternative to traditional colonoscopy, potentially increasing patient compliance due to its non-intrusive nature. This method facilitates timely detection of colorectal conditions and contributes to better outcomes in colorectal health management by enabling early identification and treatment of issues.
The primary goal of this post-processing service is to enhance radiologists' ability to accurately assess the colon, providing either an initial review or a supplemental assessment of the dataset. Additionally, it ensures the documentation of study images on PACS, maintaining a detailed record for future reference and contributing to consistent and thorough patient care.
