[Standardization of gastric emptying scintigraphy with egg white labeled with 99mTc-sulfur colloid].

Background: Gastric emptying scintigraphy has become the gold standard, by excellence, in gastric emptying studies. This method must be standardized for the correct interpretation of results. The ideal protocol must be performed with an egg sandwich or egg white poder, both labeled with 99mTc sulphur colloid.

[Usefulness of scintigraphy images with 111In-CYT-103 in the diagnosis of colonic and rectal recurrence].

Objective: To determine the effectiveness of radioimmunoscintigraphy (RIC) with 111In-CYT-103 in detecting the extension of malignant disease in patients surgically treated for colorectal adenocarcinoma under suspicion of recurrence in comparison to CT scan (computed tomography) and exploratory laparotomy.

Design: Prospective and observational study.

Material And Methods: A total of 26 patients under suspicion of recurrence, with a total of 31 lesions.
