Hepatic artery thrombosis after liver transplantation is a devastating event requiring emergency retransplantation in most patients. Early clinical signs are often nonspecific. Before duplex sonography (combined real-time and pulsed Doppler) capability was acquired in October 1984, 76% of all transplants in this institution referred for angiography with a clinical suspicion of hepatic artery th...

Traditionally, application of ultrasound imaging on vocal fold vibration has been limited by the frame rate of dynamic sonography. When the frame rate fs is lower than half of the vibration frequency, ambiguity in the vibration frequency evident from dynamic sonography occurs. This ambiguity is known as aliasing. We exploited the aliasing effect in dynamic 2D-mode sonography to capture the vibr...

BACKGROUND Upper abdominal sonography can help physicians to confirm the diagnosis of various hepatobiliary diseases. Teaching sonography skills to medical students is important because it may enhance their level of knowledge and overall development during their gastroenterology section rotation. Sonographic imaging is abstract and students can be easily confused when scanning the abdominal str...

OBJECTIVES We conducted a prospective blinded study to evaluate the costs, accuracy, risks, and benefits of 3-dimensional (3D) transvaginal sonography compared to hysterosalpingography. METHODS A total of 101 women aged 26 to 44 years with evidence of uterine anomalies were enrolled. All participants had routine hysterosalpingography as part of their infertility evaluation as well as 3D trans...

One-hundred-four patients with preoperative diagnoses of lumbar canal stenosis, disk herniation, or a combination of both were evaluated with intraoperative sonography with the intent of (1) describing the sonographic characteristics of herniated disks and distinguishing these from bulging anuli, epidural fat, scar tissue, and spondylolisthesis; (2) establishing criteria for adequate decompress...

Purpose: The purpose of this study was to examine the usefulness of abdominal sonography in the diagnosis of necrotizing enterocolitis (NEC). Methods: We reviewed the medical records of 51 neonates who were diagnosed with NEC in the neonatal intensive care unit at Yeouido St. Mary’s Hospital of the Catholic University in Korea between January 2008 and December 2012. The neonates under­ went abd...

The use of intraoperative sonography was analyzed in 24 patients with spinal dysraphism and syringohydromyelia in order to determine the role of real-time sonography in the surgical management of these patients. Specific diagnoses included tethered cord (nine), syringohydromyelia (seven), congenital tumor unassociated with a tethered cord (four), diastematomyelia (three), and occult sacral meni...

BACKGROUND Ultrasound has become a routine part of care for pregnant women in Uganda, being one of a range of techniques used in screening. However, it differs from most others because it allows women to view their babies. Routine obstetric sonography is now globally recognized as one of the ways through which maternal mortality can be reduced. This study aimed at finding out the knowledge, att...
