Book excerpt: In recent years, CT and MRI have provided powerful new tools for diagnosing lesions of the globe and orbit. At the same time, the great variety and distribution of these lesions - many of which are seen rarely in the clinic - have continued to make diagnosis difficult for most general radiologists. Combining the experience of both radiologists and ophthalmologists, this important work offers the most complete coverage of globe and orbit imaging available today. Practically organized by anatomical region, this book features hundreds of high-quality radiographic images and will enable correct diagnosis of a broad range of globe and orbit disorders. Highlights include: Detailed help in diagnosing disorders of the ocular cone, the globe, the preseptal and subperiosteal compartments, the lacrimal gland, the orbital apex, the cavernous sinus, and the extraocular muscles Convenient organization based on anatomy rather than imaging technique, and full coverage of both normal and abnormal findings More than 300 superior-quality radiographs and line drawings A thorough integration and comparison of CT and MR data for each disorder A complete clinical reference, Imaging of the Globe and Orbit is a must for radiologists who wish to reach accurate diagnoses and ensure a high level of patient care.

Available in PDF, EPUB and Kindle. Book excerpt: The body motion of patients during magnetic resonance imaging (MRI) causes significant artifacts in the reconstructed image. Artifacts are manifested as a motion induced blur and ghost repetitions of the moving structures, which obscure vital anatomical and pathological detail. The techniques that have been proposed for suppressing motion artifacts fall into two major categories. Realtime techniques that attempt to prevent the motion from corrupting the data by restricting the data acquisition times or motion of the patients, and post-processing techniques that use information embedded in the corrupted data to restore the image. The post-processing techniques usually demand an appropriate model of the motion that requires the parameters be determined in order to invert the data degradation process. However, motion is manifested differently depending on the time and duration it occurred during Magnetic Resonance (MR) data acquisition. Estimating motion parameters from such cases are heavily based on assumptions and the reconstructed image is compromised on either contrast or resolution. A major challenge in high resolution MR imaging of the orbit (eyeball and associated tissues in the eye socket) is image degradation by artifacts resulting from eye movements and eyelid blinks. In this thesis a novel method for motion correction has been developed by incorporating an optical sensor that detects these eye movements during MR scan acquisition without generating signal artifacts, and which is not affected by either the strong static magnetic field or the pulsed field gradients. Detection of the subjects eye movements and blinks is essential for determining the exact times during the MR scan when each such movement occurred. This thesis presents a method for refining orbital MRI techniques to compensate for the effects of blinking and fixation instability. It employs an eye tracker system to track eye/eyelid movements in the MRI studies of strabismus in humans that is based on infrared (IR) light reflection. It incorporates custom-fabricated optical fiber probes that illuminate the eye with low intensity infrared light, while eye/eyelid movements are detected by changes in ocular surface reflectance transmitted by another optical fiber cable coupled to a photodiode. Additionally, there is another light source that serves as a visible point target for ocular fixation during MRI scanning. The volunteer's eye movements are recorded simultaneously while the orbit is scanned using MRI. The output signal from the detector is amplified and synchronized in time with the MR acquired data. Image data corrupted by motion is flagged so that the affected data can be removed during image reconstruction. The purpose of this experiment is to outline experimental protocols for acquiring and correcting the above mentioned images in high quality, discuss these protocols from a wide range of perspectives, and finally present some observations on pilot data from volunteer subjects as well as patient with pathology. The MRI methodology developed was able to suppress motion artifacts considerably to provide interpretable MRI images.
