[Single-photon emission computed tomography for the assessment of ventricular perfusion and function].

Background: Single-photon emission computed tomography (SPECT) can be used as a non-invasive tool for the assessment of coronary perfusion.

Aim: To assess ventricular perfusion and function by SPECT in patients with single vessel coronary artery disease.

Material And Methods: Among patients with indications for a coronary artery angiography, those with significant lesions in one vessel, were selected for the study.

Could the [14C]urea breath test be proposed as a 'gold standard' for detection of Helicobacter pylori infection ?

Background: The urea breath test (UBT) with a microdose of [14C] is a non-invasive and simple method for the assessment of gastric infection by Helicobacter pylori. The aim of this study was to compare the [14C]UBT with invasive methods widely used for assessment of H. pylori gastric infection, including histology with hematoxylin-eosin staining, the gastric smear technique using Giemsa staining, and the biopsy urease test.

[Myocardial contraction and ventricular function in normal subjects evaluated with isotopic ventriculography and phase analysis].

Normal heart contraction was studied in 20 healthy subjects (14 males and 6 female, mean age 33 years). Rest radioventriculography and phase analysis were used. Ejection fraction was 66 +/- 7% for the LV and 53 +/- 7% for the RV (p < 0.

[Immunoscintigraphy in stomach neoplasms with anti-CEA BW 431/26 monoclonal antibodies marked with Tc 99 m].

A 57 year old female had a tubular gastric adenocarcinoma confirmed by endoscopy and radiologic studies. Echotomography of the abdomen revealed multiple adenopathies. Immunoscintigraphy with 99mTc labeled anti-CEA BW 431/26 monoclonal antibody was performed.
