Computed tomographic (CT) gastrography, also called virtual gastroscopy (VG), is a non invasivenoninvasive procedure for the detection of gastric abnormalities.
Advantages
- rapid and
non invasivenoninvasive exam - offers information about local tumor invasion, lymph node and distant metastasis in cases of gastric cancer
Indications
- early detection of gastric carcinoma
- to examine gastric abnormalities, e.g. hiatus hernia, polyps and ulcers
- post
surgical-surgical assessment of the stomach
Technique
- patient preparation, fasting at least 8 hours before the exam
- bowel distension, optimal gastric distention is a fundamental prerequisite for CT gastrography data evaluation; collapsed gastric wall may mimic disease or obscure underlying pathology
- negative oral contrast medium with effervescent granules is effective for optimal gastric distension
Data acquisition and analysis
- CT scanning is ideally performed on a multi-detector computed tomography (MDCT) with a thin collimation
- data interpretation with the use of two-dimensional (2D) and three
dimensional-dimensional (3D) displays for proper evaluation
