Hypopharyngeal perforation caused by intraoperative transesophageal echocardiography
Abstract Intraoperative transesophageal echocardiography (TEE) is an invaluable tool for cardiac surgical decision-making. TEE is considered reasonably noninvasive and safe, but insertion and manipulation of the TEE probe can lead to complications. Here, we report a patient with aortic stenosis who experienced TEE-associated hypopharyngeal perforation at the pyriform sinus complicated by esophageal trauma, pneumomediastinum and pneumoretroperitoneum. Based on this case, we suggest that rare complications be kept in mind when using TEE intraoperatively. (Source: Journal of Medical Ultrasonics)

Relationship of intraoperative ultrasound characteristics with pathological grades and Ki-67 proliferation index in intracranial gliomas
Conclusions IOUS is a very useful imaging technique not only in defining the borders but also in characterizing the tumoral tissue. The IOUS characteristics of the glial tumors were a valuable tool in differentiating the grades of the glial tumors and might have a relationship with the Ki-67 proliferation index. We think this theory requires further investigation in more detailed comparative studies with larger numbers of patients. (Source: Journal of Medical Ultrasonics)

Primary lymphoma of the spleen mimicking simple benign cysts: contrast-enhanced ultrasonography and other imaging findings
We report on a case of incidentally detected primary splenic lymphoma mimicking simple benign cysts on abdominal ultrasonography. On contrast-enhanced ultrasonography (CEUS), the lesions showed isoenhancement in the arterial phase with progressive washout and marked hypoenhancement in the parenchymal phase. This pattern enabled us to suspect the malignant nature of the disease, thus preventing a dangerous misdiagnosis. Accordingly, further characterization with other imaging studies (computed tomography, magnetic resonance imaging, and positron emission tomography) was pursued based on CEUS and taking into account the pati...

Three-dimensional high-definition flow in the diagnosis of placental lakes
Abstract Placental lakes are sonolucent areas often found in the normal placenta. Most of them are asymptomatic. They are sometimes related to placenta accreta or intrauterine fetal growth restriction, among other conditions. Although Doppler sonography is useful for evaluating noxious placental lakes, it is not easy to adapt Doppler studies to conventional two-dimensional color Doppler sonography because of the low-velocity blood flow and high vascularity in the placenta. Here, we demonstrate how three-dimensional high-definition imaging of flow provides a novel visual depiction of placental lakes, which helps s...

In vitro experiment using porcine artery for evaluation of ultrasonic measurement of arterial luminal surface profile
Abstract Introduction In early-stage atherosclerosis, the luminal surface of the arterial wall becomes rough because of detachment of endothelial cells and degeneration of the internal elastic layer. Therefore, it would be useful if minute luminal surface roughness of the carotid arterial wall, which occurs in the early stage of atherosclerosis, could be measured noninvasively with ultrasound. The injured luminal surface is believed to have roughness of a few hundred micrometers. However, in conventional ultrasonography, the axial resolution of a B-mode image depends on the ultrasonic wavel...
