Small-bowel obstruction from adhesive bands and matted adhesions: CT differentiation.
The purpose of this study was to evaluate the CT findings that can help to differentiate small-bowel obstruction (SBO) due to adhesive bands from SBO caused by matted adhesions. ⋯ CT is useful for differentiating SBO caused by adhesive bands from SBO due to matted adhesions.

ReviewCT diagnosis of acute mesenteric ischemia from various causes.
Acute mesenteric ischemia can be caused by various conditions such as arterial occlusion, venous occlusion, strangulating obstruction, and hypoperfusion associated with nonocclusive vascular disease, and the CT findings vary widely depending on the cause and underlying pathophysiology. The aim of this article is to review the CT appearances of acute mesenteric ischemia in various conditions. ⋯ Recognition of characteristic CT appearances and the variations associated with each cause may help in the accurate interpretation of CT in the diagnosis of mesenteric ischemia.

Sonography of patients with hemiplegic shoulder pain after stroke: correlation with motor recovery stage.
This study was performed to clarify the cause of shoulder pain using sonography and to evaluate the relationship between the sonographic findings and the motor recovery stages in stroke patients with hemiplegic shoulder pain. ⋯ The cause of shoulder pain was variable and there was no correlation between the stages of motor recovery and the grades of sonographic findings in patients with hemiplegic shoulder pain.

Comparative StudyComparison of indirect isotropic MR arthrography and conventional MR arthrography of labral lesions and rotator cuff tears: a prospective study.
The purpose of our study was to prospectively compare the diagnostic accuracy of 3D isotropic indirect MR arthrography with conventional sequences of indirect MR arthrography for the diagnosis of labral and rotator cuff lesions on a 3-T MR unit. ⋯ Three-dimensional isotropic MR arthrography sequences with multiplanar reconstruction can provide a similar capability for the diagnosis of labral and rotator cuff lesions as conventional MR arthrography sequences but in a shorter imaging time.

Carotid artery abnormalities and leukoaraiosis in elderly patients: evaluation with MDCT.
Several studies have shown that leukoaraiosis is a clinically relevant condition. Patients with leukoaraiosis have a negative prognosis in terms of death, stroke, and myocardial infarction. The aim of this study was to evaluate whether the presence and severity of leukoaraiosis correlate with degree of carotid stenosis and the presence of specific types of plaque (fatty, mixed, calcified) in a group of elderly patients with clinical indications for MDCT. ⋯ The results of this study showed a statistically significant correlation between the presence and severity of leukoaraiosis and degree of carotid stenosis. A trend toward increased risk of development of leukoaraiosis in carotids with fatty plaques also was observed. The data confirmed that the development of leukoaraiosis is strongly correlated with age.
