Related Imaging Modalities
Abdominal ultrasound or CT can help evaluate structural abnormalities of the stomach and rule out obstruction.
Ultrasound
Ultrasound uses sound waves to create real-time images. Commonly used for pregnancy monitoring and examining organs like the heart, liver, and kidneys.
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.

Delayed Gastric Emptying Scan: What It Shows, Cost & Prepara
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.
Diabetic Gastroparesis Gastric Emptying Scan: What It Shows,
Markedly delayed gastric emptying in diabetic patients, typically showing >60% retention at 2 hours and >10% retention at 4 hours. The stomach often appears dilated with retained radiolabeled meal. Minimal progression of activity into the small intestine throughout the 4-hour study period.
Post-Surgical Gastric Emptying Scan: What It Shows, Cost & P
Variable patterns depending on surgery type. Post-fundoplication may show delayed solid emptying with preserved liquid emptying. Post-bariatric surgery can show either delayed or rapid emptying. Post-vagotomy typically shows marked delay with dilated stomach. Key findings include retention >10% at 4 hours for delayed emptying or rapid early emptying for dumping syndrome.
Pediatric Gastric Emptying Scan: What It Shows, Cost & Prepa
In children, normal gastric emptying varies significantly with age. Infants have naturally slower emptying. By age 2-3 years, values approach adult norms. Delayed emptying shows >50-70% retention at 2 hours (age-adjusted). Key findings include failure of progressive emptying, retained gastric activity at 4 hours, and correlation with symptoms such as vomiting, regurgitation, and feeding difficulties.
Gastroparesis Scan: What It Shows, Cost & Preparation
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: What It Shows, Cost & Preparati
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.
