In Utero Sonographic Findings of Giant Hepatic Hemangioma and Associated Perinatal Complications: A Report of Two Cases
We describe herein two patients with a giant hepatic hemangioma detected antenatally, both with perinatal complications. In Case 1, a fetal intra-abdominal mass, measuring 63 mm × 50 mm × 74 mm, was observed below the right lobe of the liver, and the presumptive antenatal diagnosis of hepatic hemangioma was made at 37 weeks of gestation. Antenatal imaging suggested an intratumoral hemorrhage, but postnatal clinical findings refuted this diagnosis. However, progressive thrombocytopenia and coagulopathy were noted just after birth, resulting in the diagnosis of Kasabach–Merritt syndrome. In Case 2, our ultrasound...

Ultrasonographic Features of Tuberculous Cervical Lymphadenitis
Publication date: September 2014 Source:Journal of Medical Ultrasound, Volume 22, Issue 3 Author(s): Chen-Han Chou , Tsung-Lin Yang , Cheng-Ping Wang Making an accurate diagnosis of tuberculous cervical lymphadenitis (TCL) has been a problem to clinicians because it is a versatile masquerader and is often confused with lymphomas or cervical metastases. Ultrasound (US) has advantages over other examination modalities in that it is noninvasive, inexpensive, time-saving, and able to guide procedures such as fine-needle aspiration and core-needle biopsy. It is increasingly being recognized as a primary tool for the eval...

Applications of Intraoperative Ultrasound in Epilepsy Surgery for Focal Cortical Dysplasia
In this report, we present a convenient tool to define the boundary of FCD and improve the surgical outcome. The safe and effective method of image guidance by intraoperative ultrasound was demonstrated, and is time-saving and of a high resolution. In the future, intraoperative ultrasound will be useful in defining subtle epileptogenic lesions, especially when the surgeons encounter FCDs. (Source: Journal of Medical Ultrasound)

Accuracy of Transvaginal Ultrasonography for Detecting Intrauterine Lesions at a Taiwan Medical Center: A Correlation with Ultrasound and Hysteroscopic Histopathology
Conclusion TVUS had a sensitivity of 72.9% for diagnosing focal lesions. An ET ≥ 8 mm had a lower sensitivity for diagnosing benign intrauterine focal lesions. In our retrospective study group, AUB was not a good predictor for diagnosing focal intrauterine lesions even after treating ET as a fixed variance. (Source: Journal of Medical Ultrasound)

Bone Tissue in Down Syndrome Patients Deteriorates Following Aging: A Study Based on Bone Ultrasound Analysis
Conclusion This study showed that BUA is sufficiently sensitive to highlight the bone degradation that occurs at the end of adolescence and in adulthood in individuals with DS. In addition, BUA and stabilometric performances were able to distinguish DS patients from controls in the two older age groups, indicating that bone tissue and postural control of DS patients deteriorate with aging.

Doppler Study of the Fetal Renal Artery in Oligohydramnios with Post-term Pregnancy
Conclusion In oligohydramnios in the context of post-term pregnancies, there is an increased resistance in the fetal renal vascular bed. The reduced FRABF suggests that increased arterial impedance is an important factor in the development of oligohydramnios. This study supports the idea of increased vascular resistance in the fetal renal bed in patients in post-term pregnancies. We think that fetal renal artery Doppler measurement should be part of a routine daily clinical obstetric practice in post-term pregnancies with oligohydramnios.

Investigating the Influence of the Physiological Environment on Quantitative Contrast-enhanced Ultrasound Imaging
Conclusion It has been re-established that as temperature increases from room temperature to body temperature, considerable signal is lost and attenuation and backscatter increase with temperature. Blood cells surrounding the bubbles do alter the attenuation; however, they do not have any effect on the backscatter by the bubbles. This result is different from previous studies, and therefore, more work must be done to validate these results in a more sophisticated experimental setup. Confinement of bubbles inside small vessels affects both attenuation and backscatter. Hence, while designing experiments, care must be taken a...

Hemodynamics of the Fetal Renal Artery in Cases of Isolated Oligohydramnios Between 35 Weeks' and 40 Weeks' Gestation
Conclusion Our study shows that isolated oligohydramnios is related to fetal hemodynamic changes in the fetal renal artery and the regulatory mechanisms of the vascular bed. (Source: Journal of Medical Ultrasound)
