Screening For Intermediate And Severe Forms Of Thalassaemia In Discarded Red Blood Cells: Optimization And Feasibility, maryanne tan 2011 University of Malaya

Screening For Intermediate And Severe Forms Of Thalassaemia In Discarded Red Blood Cells: Optimization And Feasibility, Maryanne Tan

Mary Anne Tan Jin Ai

Detection and quantification of Hb subtypes of human blood is integral to presumptive identification of thalassaemias. It has been used in neonatal screening of thalassaemia and Hb variants. The use of discarded red blood cells following processing of the cord blood for stem cells provides readily available diagnostic material for thalassaemia screening. In this study, we determined the range of Hb subtypes in 195 consecutive cord blood samples collected for cord blood banking. The `cord blood samples’ analysed were those of the remaining red blood cells after the cord blood was processed for stem cell storage. Quantification of Hb subtypes ...

In-Vivo Ct Dosimetry During Virtual Colonoscopy, Jonathon W. Mueller 2011 The University of Texas Graduate School of Biomedical Sciences at Houston

In-Vivo Ct Dosimetry During Virtual Colonoscopy, Jonathon W. Mueller

UT GSBS Dissertations and Theses (Open Access)

Virtual colonoscopy (VC) is a minimally invasive means for identifying colorectal polyps and colorectal lesions by insufflating a patient’s bowel, applying contrast agent via rectal catheter, and performing multi-detector computed tomography (MDCT) scans. The technique is recommended for colonic health screening by the American Cancer Society but not funded by the Centers for Medicare and Medicaid Services (CMS) partially because of potential risks from radiation exposure. To date, no in‐vivo organ dose measurements have been performed for MDCT scans; thus, the accuracy of any current dose estimates is currently unknown.

In this study, two TLDs were affixed to ...


The Use Of Motion Analysis Technology As An Alternative Means Of Assessing Spinal Deformity In Patients With Adolescent Idiopathic Scoliosis, Matthew J. Solomito 2011 University of Connecticut - Storrs

The Use Of Motion Analysis Technology As An Alternative Means Of Assessing Spinal Deformity In Patients With Adolescent Idiopathic Scoliosis, Matthew J. Solomito

Master's Theses

Adolescent Idiopathic Scoliosis (AIS) is a three dimensional deformity of the spine that causes abnormal curvatures in the coronal and sagittal planes and abnormal vertebral rotations. The gold standard for diagnosing and tracking the progression of the deformity is through the use of repeated radiography and a patient can receive upwards of fifteen radiographic series over the course of treatment, which exposes this population to an increased risk of radiation-dependent complications.

This thesis presents the necessary calculations and the marker set required to make the motion capture technology a viable alternative to radiographs, in an effort to reduce the patient ...

Diagnosis Of Heart Failure In Primary Care, F. D. R. Hobbs, Jenny Doust, Jonathan Mant, Martin R. Cowie

Jenny Doust

Extract: Heart failure is a syndrome resulting from a structural or functional cardiac disorder. For a diagnosis of heart failure to be made, there should be symptoms or signs, such as breathlessness, effort intolerance or fluid retention, together with objective evidence of cardiac dysfunction. Heart failure is an increasingly important chronic disease syndrome, associated with poor prognosis, poor quality of life for patients, and high healthcare costs. In the general population, where all grades of heart failure are represented, 5 year mortality is around 42%; however, where the diagnosis is established during a hospital admission, 5 year mortality is between ...

Hemodynamics In The Stenosed Carotid Bifurcation With Plaque Ulceration, Emily Y. Wong 2011 The University of Western Ontario

Hemodynamics In The Stenosed Carotid Bifurcation With Plaque Ulceration, Emily Y. Wong

Electronic Thesis and Dissertation Repository

The presence of irregular plaque surface morphology or ulceration of the atherosclerotic lesion has been identified as an independent risk factor for ischemic stroke. Doppler ultrasound (DUS) is the most commonly performed non-invasive technique used to assess patients suspected of having carotid artery disease, but currently does not incorporate the diagnosis of plaque ulceration. Advanced Doppler analyses incorporating quantitative estimates of flow disturbances may result in diagnostic indices that identify plaque ulcerative conditions. A technique for the fabrication of DUS-compatible flow phantoms was developed, using a direct-machining method that is amenable to comprehensive DUS investigations. In vitro flow studies in ...

Novel Amino Acid And Ethanolamine Derivatives As Potential Tumor Imaging Agents For Positron Emission Tomography, Limin Wang 2010 University of Pennsylvania

Novel Amino Acid And Ethanolamine Derivatives As Potential Tumor Imaging Agents For Positron Emission Tomography, Limin Wang

Publicly Accessible Penn Dissertations

Malignant tumors can be detected with high sensitivity and specificity by imaging their increased metabolic rate for glucose, amino acids and fatty acids. Positron emission tomography (PET) with glucose analog [18F]FDG, which utilizes increased glucose metabolism, has become a routine clinical test for diagnosis, staging and restaging a variety of cancers. Despite the tremendous success of PET-FDG, there are some well-known limitations of [18F]FDG such as high cerebral uptake, uptake in inflammatory tissues, high excretion through urinary tract and low or negligent uptake in certain type of tumors. Decades of nuclear medicine research have lead to development of ...
