Related Imaging Modalities
Combine with CT/MRI/US for complementary detail.
CT
CT scans use X-rays to create detailed cross-sectional images of the body. They are particularly useful for detecting bone fractures, tumors, and internal bleeding.
MRI
MRI uses powerful magnets and radio waves to produce detailed images of organs and soft tissues. Excellent for brain, spine, and joint imaging.
Ultrasound
Ultrasound uses sound waves to create real-time images. Commonly used for pregnancy monitoring and examining organs like the heart, liver, and kidneys.

Delayed Gastric Emptying Scan
Delayed movement of radiolabeled meal from stomach to small intestine. More than 60% of gastric contents retained at 2 hours (vs. normal <60% at 1 hour, <10% at 2 hours). Persistent gastric activity with delayed intestinal visualization.

Gastroparesis Scan
Markedly delayed gastric emptying with prolonged retention of radiolabeled meal. Severe cases show >85% retention at 2 hours and >30% retention at 4 hours. Stomach appears enlarged with minimal intestinal activity throughout the study.
Rapid Gastric Emptying Scan
Accelerated movement of radiolabeled meal from stomach to small intestine. More than 50% of gastric contents empty within 30 minutes (vs. normal 40-60% at 1 hour). Rapid decrease in gastric counts with early intestinal visualization.
