Orientation-Independent Compositional MRI for Ordered Tissue
2019-280 – A hallmark of joint osteoarthritis (OA) is a progressive loss of cartilage that can cause painful joints or even mobility impairments if the loss becomes severe. MRI has the potential to detect early OA and thus will help scientists to develop an interventional strategy to protect or regenerate cartilage. However, conventional compositional MRI suffers from a well-known “magic angle effect... 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
