Comparative Study
Correlation between simultaneous scintigraphic and ultrasonographic measurement of gastric emptying in patients with type 1 diabetes mellitus.
To compare scintigraphic measurements of total stomach emptying of a semisolid meal with ultrasonographic measurements of changes in antral area as estimates of antral emptying in type 1 diabetic patients. ⋯ The use of standardized real-time ultrasonography to determine the gastric emptying rate of semisolid meals in diabetic patients, with the use of the change in gastric antral cross-sectional area in a single section of the stomach 15 and 90 minutes postprandially, offers a valid method for clinical practice.

To report our experience in the assessment of splenic trauma with contrast-coded sonography and a second-generation contrast medium. ⋯ Contrast-enhanced sonography is a promising tool in the assessment of splenic trauma. In institutions where sonography is used as the initial procedure, this technique may increase its effectiveness.

The value of transthoracic sonography in diffuse parenchymal lung disease is not established. This prospective study was conducted to analyze pleural and parenchymal alterations in patients with diffuse parenchymal lung disease by transthoracic sonography and to compare the results with the findings of a control group. ⋯ Diffuse parenchymal lung disease should be considered if multiple comet tail artifacts distributed over the whole surface of the lung together with a thickened and irregular, fragmented pleural line are visible. Transthoracic sonography may reflect the distribution of pleural involvement and may show subpleural alterations.

To evaluate the feasibility of sonographically guided antegrade common femoral artery puncture and superficial femoral artery access. ⋯ Sonographically guided antegrade common femoral artery puncture and selective cannulation of the superficial femoral artery are feasible and safe. They may be used as adjunctive modalities in difficult cases of common femoral artery access.
