Our group develops new experimental techniques in nuclear magnetic resonance (NMR) spectroscopy, and applies those techniques to systems of interest in biology and materials science.
For example, we have developed new NMR techniques for determining the atomic-scale structure in non-crystalline solids, and have applied those methods to the membrane protein rhodopsin and to the class of inorganic network solids called zeolites. We are currently working on extending solid-state NMR to the study of samples at very low temperatures, which will allow us to achieve higher signal strength and allow the study of cryogenic physical phenomena such as quantum rotation by NMR.
We have also demonstrated the existence of nuclear spin states with unusually long lifetimes in room-temperature liquids, and are currently exploring the possibilities of exploiting such long-lived nuclear spin states for NMR imaging.

This page contains an overview of several types of MRI modalities (structural, functional, and diffusion).
The basic measurement protocols are described and there are links to development plans and more detailed processing strategies. There are several typical protocols users run. These protocols involve a combination of scans. We document the most widely used protocols in this list. Click on specific links to see protocol details.

Simultaneous Multi-Slice EPI The CNI, in collaboration with GE, is implementing simultaneous multi-slice EPI (also known as multiband EPI, multiplexed EPI, or, as we like to call it, "mux EPI"). Imaging - INTRUSTWeb. ARFI Prostate Imaging | Nightingale Laboratory. Prostate cancer is the most common cancer and the second leading cause of cancer death in American men.
Early diagnosis is essential for better treatment and increasing survival rate. Although the current screening techniques, antigen (PSA) blood testing and digital rectal examination (DRE) are considered sensitive enough for cancer screening, follow-up biopsies have significant shortcomings. Without a good imaging technique to target the needle biopsy in the prostate gland, only about 25% of tests are positive for cancer in more than 1 million prostate biopsies performed each year; the false negative rates range from 25-45% based on the first time biopsy.
Although imaging techniques are essential for cancer diagnosis, imaging the structures and lesions within prostates has been a challenging task. We have demonstrated that ARFI imaging can clearly portray zonal anatomy and some cancerous lesions in the prostate in ex vivo studies using a linear array. Zhai L, Madden J, Foo W, et al. ObTiMA | p-medicine. ObTiMA is an ontology-based clinical trial management system intended to support clinicians in both designing and conducting clinical trials. The design phase is facilitated by the Trial Builder in which all aspects of a clinical trial can be specified: A trial chairman can define the outline and metadata of a trial in a master protocol to describe, e.g., trial goals or administrative data. He can further setup treatment plans for guiding clinicians through individual patient treatment where events, e.g., surgery or chemotherapy, can be defined with all necessary information. In addition, the particular treatment order can be freely setup on a timeline and so can treatment stratifications and randomizations to be applied for a patient.
A Case Report Form (CRF) can be assigned to each treatment step to collect documentation data. The ontology-based creation of CRFs in the Trial Builder is one of ObTiMA's major functionalities. ObTiMA itself is composed of different modules. Three tiny grills deliver high contrast X-rays. Mammography scans with lower dose and higher contrast – that’s the declared goal of Dr Nik Hauser, Medical Director of the Women‘s Clinic and Director of the Interdisciplinary Breast Centre at Kantonsspital Baden, Switzerland, and Professor Marco Stampanoni of Paul Scherrer Institute in Villigen, Switzerland.
Nik Hauser MD By building upon a procedure used in materials research to cull more information from X-rays the added significant value to mammography for breast cancer diagnosis. When passing through tissue, X-rays are not only absorbed but also refracted and scattered. The researchers used this additional information to generate breast scans with more detail and higher contrast that show even minute tissue changes. ‘While this principle is theoretically suited for any anatomy, it presented itself for breast scans, because of the high proportion of soft tissue in the breast, which means the effects are particularly well visible,’ Dr Hauser explained.
IEP 5 | Image Exchange Portal : The National Data Sharing Network. Peate. PEATE - Perl Event-related Average Timecourse Extraction Peate is intended as a companion tool to FSL. It produces average signal timecourses for a specified epoch surrounding all events of a given type, within a region of interest. Note that if your events are very close together in time, hemodynamic responses will be overlapping; Peate does not attempt to deconvolve the response to each event to resolve this overlap, it simply does selective averaging. PEATE VERSION 3.01, October, 2013 I've recompiled Peate and fixed a few things to bring it into the modern era. Plotting now works again out of the box.

UK researchers are working on a new MRI technique called hyperpolarised MRI – or Dynamic Nuclear Polarisation (DNP) – that can utilise more of the available nuclei than traditional MRI, helping to overcome some of its limitations by increasing sensitivity 10,000-fold or more. DNP is part of a longer-term aim to improve cancer mortality with the help of novel cancer imaging tools. Dr Ferdia Gallagher, Cancer Research UK Clinician Scientist Fellow at CRUK Cambridge Research Institute & the University of Cambridge, said that MRI has the power to distinguish different molecules non-invasively within tumours.
‘The concentration of these can report on how metabolically active the cancer is and its rate of growth – both of which are important for predicting survival and for determining appropriate cancer therapy,’ said Dr Gallagher. Dr Gallagher: ‘There are many unmet needs in clinical oncology where imaging is likely to play a role in helping patients of the future. Home. UK Imaging Informatics Group >> Welcome.

NeuroImage - Single-shot T2* mapping with 3D compensation of local susceptibility gradients in multiple regions. Abstract Macroscopic magnetic field inhomogeneities severely limit sensitivity of blood oxygenation level-dependent (BOLD) functional MRI (fMRI) in frontal and central brain regions close to brain stem.
A single-shot multiecho echo-planar imaging method (TurboPEPSI) was developed that combines quantitative T2* mapping with gradient compensation of local susceptibility inhomogeneities in multiple volumes of interest (VOIs). Gradient compensation was optimized in individual subjects based on magnetic field mapping and applied at selected echo times, interleaved with acquisition of uncompensated echoes. Intrinsic T2* values from uncompensated echoes were obtained in real-time simultaneously with effective T2* values from gradient compensated echoes. It is demonstrated that up to three VOIs can be compensated in a single excitation, in addition to collecting uncompensated data, using 8-echo acquisition on a clinical 1.5 Tesla scanner.

From NAMIC This page should serve as a place where information about DICOM and DWI/DTI data can be maintained. With time, this information could be used as part of automated solutions for learning all the necessary DWI-related information from a DICOM series. A collection of tools for DICOM is here. As long DICOM support for DWI information is vendor-specific and/or non-conformant with the info here, the Nrrd format provides a means of recording the DWI-specific information once it is known. DICOM for DWI The recommended tags to use in DICOM are as follows: 0018 9075 CS 1 Diffusion Directionality 0018 9076 SQ 1 Diffusion Gradient Direction Sequence 0018 9087 FD 1 Diffusion b-value 0018 9089 FD 3 Diffusion Gradient Orientation 0018 9117 SQ 1 MR Diffusion Sequence 0018 9147 CS 1 Diffusion Anisotropy Type These are defined in Supplement 49.
