The role of ultrasound in central neuraxial blockade has been underappreciated, partly because of the relative efficacy of the landmark-guided technique and partly because of the perceived difficulty in imaging through the narrow acoustic windows produced by the bony framework of the spine. However, this also is the basis for the utility of ultrasound: an interlaminar window that permits passag...

Several groups have developed methods for registering an individual's 3D MRI by deforming a standard template. This achievement leads to many possibilities for segmentation and morphology that will impact nuclear medical research in areas such as activation and receptor studies. Accordingly, there is a need for methods that can assess the accuracy of intersubject registration. We have developed...

introduction: computed tomography (ct) is an imaging technique with gives us an opportunity to review cross sections of the body in live animals. in veterinary medicine although ct is mostly used for diagnostic purposes in small animals, but in recent years ct also has been used as a non invasive modality in non clinical studies. jebeer gazelle (gazella bennettii) is one of the species of the g...

BACKGROUND Central venous access is often necessary for the administration of fluids, blood products, and medications. Several approaches to supraclavicular subclavian venous access have been described. This study examines the effectiveness of central venous catheter placement utilizing an alternative set of anatomic landmarks for supraclavicular subclavian vein access. METHODS This was a two...

BACKGROUND Transoral robotic surgery (TORS) has facilitated organ-preserving surgery of the larynx. It has also presented a change in the surgical perspective. We performed cadaveric dissections using the robot to highlight the vascular and muscular anatomy of the supraglottic larynx. METHODS Cadaveric specimens underwent injection of their vasculature, and after injection a robotic surgical ...

Anatomic aberrations of the femur and tibia secondary to trauma, congenital defects, and prior surgery present challenges for the reconstructive knee surgeon because of an altered mechanical axis and distorted anatomic landmarks. Five patients with arthritis of the knee and extra-articular femoral and/or tibial deformity, retained hardware, or intramedullary (IM) implants underwent total knee a...

The application of whole-body scanners with a wide aperture cone to neuroradiology permits examination of the head in the sagittal plane. This method yields better definition of anatomic structures such as the inner and outer supra- and infratentorial cerebrospinal fluid spaces, the major vessels, and all structures of the posterior fossa close to the midline with negligible artifacts. By mono-...
