Background:
Prevention and treatment of peritoneal metastases from colon cancer is currently under a critical reevaluation. An expanded role of the radiologist in imaging the peritoneum and extrahepatic structures is crucial to progress in this endeavor.
Methods:
The critical role of radiology in the evaluation of a primary colon cancer and in diagnosis and assessment of recurrent colon cancer is evaluated.
Results:
For primary colon cancer the radiologist should forewarn the multidisciplinary team of patients whose malignancy is at high risk for peritoneal metastases and for local recurrence. In recurrent colon cancer a quantitative assessment of the concerning radiologic features are of help to select patients for reoperation.
Conclusion:
An improved primary surgical treatment strategy and more knowledgeable patient selection for reoperation can result from this information.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
