The clinical value of transcranial color-coded duplex sonography (TCCS) in the evaluation of arteriovenous malformations (AVMs) has not yet been fully investigated. In this study, 54 intracranial AVMs confirmed by angiography were prospectively examined over 6 years. The purpose of the study was to describe their typical sonographic features and to define sensitivity for diagnosis with regard to the location of an AVM. ⋯ Transcranial color-coded duplex sonography is a valuable noninvasive method for the diagnosis and long-term follow-up of intracranial AVMs. Arteriovenous malformations located in the axial imaging plane can be more easily detected. Nevertheless, TCCS should not be used as a screening method.

Little has been reported on the relationship between left main coronary artery atherosclerosis and carotid ultrasonographic results. We evaluated the association between carotid and coronary atherosclerosis assessed by coronary intravascular ultrasonography (IVUS) in 45 patients. ⋯ The average of the maximum common carotid IMT was significantly correlated with left main coronary artery atherosclerosis evaluated by IVUS.

The purpose of this study was to describe the normal anatomy and abnormalities of the lumbar intervertebral disk with sonography in cadaveric specimens and to correlate the sonographic findings with pathologic findings. ⋯ High-resolution sonography is a simple imaging method that can show the normal lumbar intervertebral disk and degenerative changes in appropriate subjects. High-resolution sonography proves superior to conventional sonography for evaluation of the lumbar intervertebral disk.
