A factor currently limiting widespread... Read More

Analytic Morphomics: High Speed Medical Image Automated Analysis Method

4834 – Millions of medical imaging scans, such as computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) are taken each year to aid medical professionals in treating their patients. However, after the images have served their initial purpose, they are rarely referenced again. Recently, the informatics sciences have grown to encompass morphometry, or the... Read More

Applications of novel ErbB2 selective peptides

6579 – The membrane receptor ErbB2 (also known as HER2/neu) is a member of the epidermal growth factor receptor (EGFR) family. ErbB2 is amplified and overexpressed in many epithelial-derived malignancies including breast, ovarian, and lung cancers. Agents capable of selectively targeting ErbB2 can be used for diagnostics, prognostic indications, imaging and therapeutic applications. The... Read More

Distance-Preserving Penalty Function for Imposing Local Rigidity in Deformable Image Registration

6374 – One of the most popular diagnostics for oncology imaging is computed tomography (CT). Worldwide, the CT market accounts for 17.0 per cent of the total diagnostic medical imaging industry. As CT technology improves, physicians are able to use these tools for better approaches to patient treatment. Radiation therapy is a commonly used treatment for many types of cancers, especially in the... Read More

Luminescent Heteromatallic Metallacrown Complexes for Biological Assays and Imaging

6312 – Sensitized lanthanides are becoming increasingly important across multiple scientific industries because of their stability, long luminescence lifetimes, and narrow emission bands. In the growing field of biological assays there has been demonstrated need for luminescent dyes that emit outside of the visible range where traditional fluorescence measurements suffer from high levels of...

Rapid MRI with a spectrally tailored signal recovery pulse

6089 – A rapid incoherent steady state magnetic resonance imaging (MRI) acquisition method has been developed at the University of Michigan. Balanced steady state free precession (bSSFP) acquisition is often used in magnetic resonance imaging (MRI) due to its high signal-to-noise ratio and T2-weighting. However, bSSFP suffers from off-resonance artifacts. The proposed acquisition method offers image... Read More

Copper Catalyzed [18F]Fluorination of (Mesityl)(Aryl) Iodonium Salts

6172 – Molecular imaging techniques allow us to see biological processes as they happen inside the human body. Positron electron tomography (PET) is one such technique. It is currently used for the diagnosis of cancers, and is being increasingly used for the diagnosis of heart conditions. PET can also be used for the diagnosis of neurological disorders such as Alzheimer’s Disease, Parkinson’s... Read More

Software for Analysis of Dynamic Contrast Enhanced and Dynamic Susceptibility Contrast MRI in Functional Image Analysis Tool

5496 – Dynamic contrast enhanced (DCE) and dynamic susceptibility contrast (DSC) MRI Dynamic contrast enhanced (DCE) and dynamic susceptibility contrast (DSC) MRI, which can be acquired within routine clinical MRI sessions with only a few extra minutes, have been shown to be of great clinical value for diagnosis, staging, therapy guidance and assessment of treatment response for many diseases. ...

Effective photothermal therapy using magnetic nanoparticles

5806 – Administered magnetic nanoparticles aggregate in solid tumors and absorb near-infrared radiation to destroy tumor cells. Currently, gold nanostructures are used in photothermal therapy (PTT) as near-infrared-absorbing nanoparticles. However, gold nanoparticles can undergo melting with laser treatment, are too large to effectively accumulate in solid tumors, and require multiple steps for... Read More

Subvolume Identification from DCE MRI for Prediction of Treament Response

5352 – The impact of therapy on cancer as well as normal organs is hard to predict by conventional means, including tumor size, mean value of physiological image parameters in the tumor, or even voxel-by-voxel analysis of physiological images taken before and during treatment. Additional information for tumor response to therapy might be obtained through physiological parameters, which however... Read More

Subvolume Identification for Prediction of Treatment Outcome

5351 – The impact of therapy on cancer as well as normal organs is hard to predict by conventional means, including tumor size, mean value of physiological image parameters in the tumor, or even voxel-by-voxel analysis of physiological images taken before and during treatment. A change in tumor size often occurs too late for prediction of response. A mean value of a physiological image parameter... Read More

Method for Rapid Incoherent Magnetic Resonance Imaging with T2-Weighing

5144 – Magnetic Resonance Imaging (MRI) is a technology that uses magnetic signals to show the different tissues inside the body creating non-invasive images of the inside of the human body. In 2009 there were over 69 million MRI scans performed in the U.S. alone. The imaging procedure is used commonly for diagnosis for every part of the body, from the brain to the knee. With each scan costing... Read More

Error Analysis and Correction of MRI ADC Measurements for Gradient Nonlinearity

5391 – Diffusion MRI is used in a large fraction of clinical MRI exams, where quantitative “Apparent Diffusion Coefficient (ADC)” values are broadly used as biomarkers of therapy response and also reflect other tissue qualities such as cellular density, edema, and necrosis. However, current ADC measurement is in error due to inevitable imaging gradient non-linearity. Known methods that implement... Read More

Gating of Cardiac X-Ray CT Scans from Projections

2878 – One of the challenges associated with cardiac computed tomography (CT) imaging is resulting artifacts caused by the movement of the beating heart.
