Stomach cancers and gastrointestinal stromal tumors (GISTs) are serious conditions that affect the stomach and can lead to symptoms such as pain or weight loss. These tumors can be easily detected in MRI, as the method provides detailed images of the stomach wall and surrounding tissues. Stomach cancers often appear as irregular thickening of the stomach wall, while GISTs are visible as nodular structures. MRI helps determine the size and location of these tumors, enabling early diagnosis and targeted treatment.
