This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The simultaneous acquisition of PET and MRI data shows promise to provide powerful capabilities to study disease processes in human subjects, guide the development of novel treatments, and monitor therapy response and disease progression. A brain-size PET detector ring insert for an MRI system is being developed that, if successful, can be inserted into any existing MRI system to enable simultaneous PET and MRI images of the brain to be acquired without mutual interference. The PET insert uses electro-optical coupling to relay all the signals from the PET detectors out of the MRI system using analog modulated lasers coupled to fiber optics. Because the fibers use light instead of electrical signals, the PET detector can be decoupled from the MRI making it partially transparent to the RF field of the MRI. Also, the number of laser-fiber channels in the system was reduced using techniques adapted from the field of compressed sensing. Using the fact that incoming PET data is sparse in time and space, electronic circuits implementing constant weight codes uniquely encode the detector signals in order to reduce the number of electro-optical readout channels by greater than 8-fold. Two out of a total of sixteen electro-optical detector modules have been built and tested with the entire RF-shielded detector gantry for the PET ring insert. The two detectors have been tested outside and inside of a 3T MRI system to study mutual interference effects and simultaneous performance with MRI. Preliminary results show that the PET insert is feasible for high resolution simultaneous PET/MRI imaging for applications in the brain.

Available in PDF, EPUB and Kindle. Book excerpt: The combination of two leading imaging techniques – magnetic resonance imaging and positron emission tomography – is poised to have a large impact and has recently been a driver of research and clinical applications. The hybrid instrument is capable of acquiring both datasets simultaneously and this affords a number of advantages ranging from the obvious, two datasets acquired in the time required for one, through to novel applications. This book describes the basics of MRI and PET and then the technical issues and advantages involved in bringing together the two techniques. Novel applications in preclinical settings, human imaging and tracers are described. The book is for students and scientists entering the field of MR–PET with an MRI background but lacking PET or vice versa. It provides practical details from experts working in the area.
Download or read book Radio frequency Penetrable Positron Emission Tomography PET Insert for Simultaneous PET and Magnetic Resonance Imaging written by Chen Ming Chang and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Combining medical imaging modalities that measure complementary, multi-parametric information such as anatomy and biochemistry about a patient's disease has been proven to provide tremendous clinical value. In recent years, hybrid positron emission tomography (PET)/magnetic resonance imaging (MRI) has risen to the cutting edge of multi-modality medical imaging technology. Unfortunately, the cost of purchasing a commercially-available integrated PET/MRI scanner is unaffordable for most healthcare providers, therefore limiting the dissemination of PET/MRI and its long-term potential. This dissertation presents the development of a radio-frequency (RF)-penetrable PET insert that can be placed into any existing MRI system to acquire simultaneous PET and MRI images. The insert approach can reduce the cost barrier for an existing MRI site to offer PET/MRI scans by leveraging its existing infrastructure. A brain-sized prototype PET insert with a 2.8-cm axial field-of-view (FoV) has been developed and its performance (energy, timing, spatial, system stability, and count rate) evaluated. Tomographic images of resolution and 3-D Hoffman brain phantoms have been acquired with the PET insert both outside and inside and simultaneous running with a 3T MR system. A second-generation RF-penetrable PET insert with an extended axial field-of-view (16 cm) and a coincidence timing resolution (

Book excerpt: Simultaneous positron emission tomography/magnetic resonance imaging (PET/MRI) has shown promise in acquiring complementary multiparametric information of diseases. However, designing these hybrid imaging systems is challenging due to the propensity for mutual interference between the PET and MRI sub-systems. In addition, the current high cost of permanently-integrated PET/MRI systems limits their long-term development and deployment, as well as patient accessibility. To overcome these limitations, we explored a brain-dedicated PET insert for an existing MRI system to achieve simultaneous PET/MRI. Because of its brain-dedicated design, this insert also provides superior spatial resolution and sensitivity compared to whole-body scanners. The second-generation prototype builds upon the success of the first-generation prototype, which demonstrated radio-frequency (RF)-penetrability and MR-compatibility. The new design includes additional features such as a longer axial field of view, time-of-flight (TOF) functionality, and improved portability, resulting in improved PET performance but presenting greater technical challenges for MR-compatibility. This thesis presents the development of the second-generation brain-dedicated PET insert for simultaneous PET/MRI. Our objective is to achieve high levels of both PET performance and MR-compatibility. The detailed design, architecture, experiment setup, results and analysis of the second-generation brain-dedicated PET insert are presented, highlighting the progress towards realizing a cost-efficient and effective simultaneous PET/MRI system for neurological imaging.

Download or read book Positron Emission Tomography with Computed Tomography PET CT written by Jonas Francisco Y. Santiago and published by Springer. This book was released on 2014-06-28 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Positron Emission Tomography with Computed Tomography (PET/CT) is a nuclear medicine imaging modality using positron-emitting radiotracers and a combined PET and CT scanner in order to detect and localize high radiotracer signal abnormalities. Although PET has evolved into a diagnostic modality of prime importance in oncology (with the radiotracer (F18-FDG) it was originally envisioned to image and diagnose diseases of the brain and the heart. Lack or limited experience in PET may result in an erroneous interpretation of the findings in this sensitive imaging modality. The existence of various rare cancers has resulted in scanty if not a lack of knowledge about the usefulness of PET in these interesting albeit uncommon maladies. The author, drawing from more than ten years of experience as the chairman/director of the only PET Center in the Philippines, aims to present the most interesting cases he has encountered which may be educational to those beginning their practice or even helpful to veterans of the field whose scope of practice has been limited to the most common and reimbursable indications of an FDG-PET scan.

Download or read book Radiopharmaceuticals written by Ferdinando Calabria and published by Springer Nature. This book was released on 2019-10-12 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a rapid and concise guide to PET (PET/CT and PET/MRI) molecular imaging, concentrating extensive information on PET radiopharmaceuticals in a single volume. The book reflects the rapid development of several PET tracers over the last decade, as a result of which the “traditional” PET/CT with 18F-FDG, the “cornerstone” of PET imaging, is now only one of several available options, which use different tracers for different diseases. For the same reason, PET imaging is no longer limited to the field of oncology. In the editors’ experience, students in medicine and residents in nuclear medicine and radiology have limited access to scientific papers concerning novel PET tracers. Moreover, these papers generally focus on a single PET radiopharmaceutical. With approx. 20 radiopharmaceuticals explained in detail and a wealth of images and clinical cases, the book represents a versatile, comprehensive and practice-oriented guide to PET imaging, pursuing a unique and novel approach to the clinical role of PET tracers. The book’s didactic nature also makes it an invaluable tool for residents in nuclear medicine and radiology, as well as for radiographers and clinicians in radiotherapy, oncology, hematology, cardiology and neurology.
