Abstract:
The diagnosis of cancer-associated stroke can be challenging, particularly when occult malignancy is not detected by standard evaluations. We report two patients with anticoagulation-resistant recurrent cryptogenic stroke in whom 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) successfully identified the underlying cancer after conventional tests were inconclusive. These cases highlight the value of FDG-PET/CT in uncovering malignancy-related stroke mechanisms and emphasize its role the timely diagnosis of cancer and targeted treatment in patients with cryptogenic stroke, as well as features suggestive of occult malignancy.

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...
