Abstract:
To assess the diagnostic value of ultrasonography in rectal carcinoma, the procedure was performed in 48 such cases. Stage was reliably established in the majority (95.8%) of patients. False--negative conclusion on the muscular layer integrity was made in one case and inflammatory infiltrate was misdiagnosed as cancer in another. Pararectal lymph nodes were visualized in 62% of patients whereas regional ones--in 5 (10.4%); their metastatic origin was confirmed with fine--needle aspiration biopsy and lymphography. Ultrasonic scintigraphy identified nodular lesions in the liver parenchyma in 10 cases; the malignant nature of those foci was verified in 90% by histo- and cytologic examination of samples obtained by fine--needle aspiration biopsy.

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.
