A 5-MHz Doppler probe was utilized to identify the perforating septofasciocutaneous vessels on the plantar aspect of the right and left feet of 10 healthy subjects. Each audible perforator was marked, and each foot was photographed, scanned into a personal computer, and standardized to 8 inches high by 4 inches wide. All 20 feet were then stacked together to create a composite average of all markings. Loupe aided (2.5 x magnification) dissection of a latex cast of the perforating septofasciocutaneous vessels from a fresh frozen cadaveric foot revealed similar location and distribution as the composite average described above. The Doppler probe is capable of accurately identifying the septofasciocutaneous perforating vessels, thereby, creating a vascular map of the plantar aspect of the foot useful for precise planning of advancement flap coverage for full thickness defects. Two representative case examples are presented.

Objectives: This study aimed to evaluate with ultrasonography (US) the location of GPF, the course of the GPA, and to measure palatal fibromucosa thickness.
Materials And Methods: This in vivo experiment was conducted on a group of healthy, young Turkish subjects. Using the US, the localization of the GPF, its diameter and opening type, maximum flow velocity (Vmax) and collateral branches (CB) of the GPA, and the thickness of the palatine mucosa were evaluated.

Introduction: Ultra-high-field magnetic resonance (MR) systems (7 T and 9.4 T) offer the ability to probe human brain metabolism with enhanced precision. Here, we present the preliminary findings from 3D MR spectroscopic imaging (MRSI) of the human brain conducted with the world's first 10.

Methods: 12 purpose-bred cats were used.
Understanding the Measurement of Pressure Within the Spinal Cord to Optimize Spinal Cord Perfusion Pressure Using a Porcine Model of Spinal Cord Injury.

Recent studies have reported that monitoring spinal cord perfusion pressure (SCPP) using a pressure probe to measure "intraspinal pressure" (ISP) within the subdural space at the injury site may improve the hemodynamic management of acute spinal cord injury (SCI) patients. This study aimed to investigate, within a pig model of SCI, the relationship between the ISP measured within the subdural space and the "spinal cord pressure" (SCP) measured within the spinal cord itself. Specifically, we sought to characterize the changes to ISP and SCP over time, both rostral and caudal to the injury epicenter, and in relation to native spinal cord morphometry.
