Traumatic Vs. Pathological Achilles Tendon Ruptures: A Look Into The Importance Of The Collagen Matrix And The Preferred Method Of Repair, Kathleen M. Mclean

Honors Theses

The Achilles tendon is the largest, strongest, and thickest tendon in the human body. While it may be the strongest, the Achilles tendon is also among one of the most frequently ruptured. These lower limb injuries arise as a result of athletically induced trauma or pathologically and steroidal induced trauma. While the manner in which athletic ruptures occurs can be determined on a case to case basis through the use of clinical examination, ultrasonography, and magnetic resonance imaging (MRI), the method in which the injury should be treated remains controversial. The two main methods of repair include a conservative approach …

Sar Map Of Gel Phantom In A 64mhz Mri Birdcage By Fiber-Optic Thermometry And Fdtd Simulation, Chirag Mukesh Patel

Master's Theses

As implantable medical devices are being used more often to treat medical problems for which pharmaceuticals don’t suffice, it is important to understand their interactions with commonly used medical modalities. The interactions between medical implants and Magnetic Resonance Imaging machines have proven to be a risk for patients with implants.

Implanted medical devices with elongated metallic components can create harmful levels of local heating in a Magnetic Resonance Imaging (MRI) environment [1]. The heating of a biological medium under MRI is monitored via the Specific Absorption Rate (SAR). SAR, defined as power absorbed per unit mass (W/kg), can be calculated …

Investigations Of Anatomical Connectivity In The Internal Capsule Of Macaques With Diffusion Magnetic Resonance Imaging, Kyle Andrew Ignatius Taljan

ETD Archive

Understanding anatomical connectivity is crucial for improving outcomes of deep brain stimulation surgery. Tractography is a promising method for noninvasively investigating anatomical connectivity, but connections between subcortical regions have not been closely examined by this method. As many connections to subcortical regions converge at the internal capsule (IC), we investigate the connectivity through the IC to three subcortical nuclei (caudate, lentiform nucleus, and thalamus) in 6 macaques. We show that a statistical correction for a known distance-related artifact in tractography results in large changes in connectivity patterns. Our results suggest that care should be taken in using tractography to assess …
