Cervical gouty myelopathy in two cases at King Abdulaziz Medical City
In this report, we describe two patients presented to King Abdulaziz Medical City in Jeddah with clinical features of cervical myelopathy, including neck pain, L'hermitte phenomena, quadriparesis and sensory deficit (shoulder level). Magnetic resonance imaging confirmed the presence of cervical cord compression with intrinsic cord signal abnormalities. Both patients had laminectomy and intraoperatively; severe canal stenosis was identified. A whitish cheesy material was noticed causing significant root compression. The pathology was diagnostic of gout. In this article, we present two difficult cases with interesting clinic...

An overview of elastography - an emerging branch of medical imaging.
We present a classification of elasticity measurement and imaging techniques based on the methods used for generating a stress in the tissue (external mechanical force, internal ultrasound radiation force, or an internal endogenous force), and measurement of the tissue response. The measurement method can be performed using differing physical principles including magnetic resonance imaging (MRI), ultrasound imaging, X-ray imaging, optical and acoustic signals.Until recently, EI was largely a research method used by a few select institutions having the special equipment needed to perform the studies. Since 2005 however, inc...

Multi-object segmentation framework using deformable models for medical imaging analysis
Abstract Segmenting structures of interest in medical images is an important step in different tasks such as visualization, quantitative analysis, simulation, and image-guided surgery, among several other clinical applications. Numerous segmentation methods have been developed in the past three decades for extraction of anatomical or functional structures on medical imaging. Deformable models, which include
the active contour models or snakes, are among the most popular methods for image segmentation combining several desirable features such as inherent connectivity and smoothness. Even though different approaches hav...

Factors associated with significant MRI findings in medical walk-in patients with acute headache.
CONCLUSION: Among walk-in patients who underwent MRI for acute headache with low suspicion for intracranial bleeding, 20% had a significant MRI finding. A simple clinical score identified all patients with significant findings that explained the headache. If prospectively validated, this might be a useful tool in selecting those walk-in headache patients requiring urgent cranial MRI.

Small Decline In Low-Value Back Imaging Associated With The 'Choosing Wisely Campaign, 2012-14 Medical Imaging
Choosing Wisely was launched by the American Board of Internal Medicine in April 2012 as a patient- and clinician-targeted campaign to reduce potentially unnecessary "low-value" medical services. The campaign’s impact on low- and high-value care beyond its first year is unknown; furthermore, it is unknown whether some patients such as members of consumer-directed health plans and people residing in different US regions have responded more than others. To evaluate the impact of Choosing Wisely, we used commercial insurance claims to track changes in the use of low-value imaging (x-ray, computed tomography, and ma...

Simplify Medical launches pivotal study of MRI-conditional cervical disc
Simplify Medical said today that it launched a pivotal study of its eponymous cervical disc, which is designed to be safe during magnetic resonance imaging scans.
Sunnyvale, Calif.-based Simplify said the implant is “optimized” for MRI scans in that it’s designed to eliminate the imaging artifact created by the metals used in some artificial disc replacements, using a PEEK-on-ceramic construction. The aim is to eliminate the need for computed tomography scans after implantation and the attendant patient exposure to ionizing radiation. The Simplify disc won CE Mark approval in the European Union in Febr...

Large-scale Retrieval for Medical Image Analytics: A Comprehensive Review
Medical image analytics plays a central role in clinical diagnosis, image-guided surgery and pattern discovery. Many protocols and modalities of digital imaging techniques have been adopted to generate medical images, including magnetic resonance imaging (MRI) (Slichter, 2013), computed tomography (CT) (Hsieh, 2009), photon emission tomography (PET) (Bailey et al., 2005), ultrasound (Szabo, 2004), fluorescence microscopy (Lichtman and Conchello, 2005), X-ray (Lewis, 2004) and others. Generally, these medical images reflect specific aspects (anatomy, function) of tissue types/organs that require an accurate interpretation...

Feature and Intensity Based Medical Image Registration Using Particle Swarm Optimization
AbstractImage registration is an important aspect in medical image analysis, and kinds use in a variety of medical applications. Examples include diagnosis, pre/post surgery guidance, comparing/merging/integrating images from multi-modal like Magnetic Resonance Imaging (MRI), and Computed Tomography (CT). Whether registering images across modalities for a single patient or registering across patients for a single modality, registration is an effective way to combine information from different images into a normalized frame for reference. Registered datasets can be used for providing information relating to the structure, f...
