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...

Adult-to-adult living donor liver transplantation preoperative survey using MDCT, a single medical center experience in Taiwan
This study evaluated multi-detector computed tomography (MDCT) scans performed on potential living donors for adult-to-adult liver transplantation (LDLT), with the aim of identifying significant findings that could be used to exclude potential transplantation donors. We retrospectively reviewed the medical records of 151 consecutive potential adult donors for LDLT from May 2007 to January 2015. Liver parenchyma steatosis, focal hepatic mass or intraabdominal malignancy, vascular variations, and donor liver volume were evaluated via MDCT. Grounds for excluding potential donors were also recorded and analyzed. Of the 151 pot...

FDA Cautions Cancer Patients About Medical Marijuana
The U.S. Food and Drug Administration (FDA) issued a stern warning Wednesday to companies marketing medical marijuana to cure or inhibit cancer — including mesothelioma — and cautioned patients about unsubstantiated claims. The FDA sent warning letters to four particular companies, citing deceptive marketing in violation of the Federal Food, Drug and Cosmetic Act. “We don’t let companies market products that deliberately prey on sick people with baseless claims that their substance can shrink or cure cancer,” said FDA Commissioner Scott Gottlieb in a press release Wednesday. “And we’re not going to look the o...

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...

Urinary Stone Disease: Diagnosis, Medical Therapy, and Surgical Management.
Abstract Clinical suspicion of urolithiasis should be evaluated with low-dose computed tomography as the first-line imaging modality for nonpregnant, adult patients. A period of observation may be appropriate for ureteral stones less than 10 mm, and medical expulsive therapy may be beneficial for facilitating passage of distal ureteral stones. Regardless of stone type, patients should adhere to a low-sodium diet and attempt to achieve a urine volume of more than 2.5 L daily. Individuals with calcium stones should maintain a normal calcium diet, and if stones persist, citrate therapy or thiazide diuretics in the ...

Simplify Medical closes $23m in 2nd tranche of Series B
Simplify Medical said today it closed $23.3 million as part of the second tranche of its oversubscribed Series B financing, which brought in a total of $44.3 million for the company and its namesake cervical disc replacement. The Sunnyvale, Calif.-based company’s Simplify disc is designed to be magnetic resonance imaging safe and to eliminate imaging artifacts created by metals through the use of a PEEK-on-ceramic construction. The Simplify disc won CE Mark approval in the European Union in February 2015. “Having an oversubscribed Series B is a testament to the large opportunity presented by the Simplify Dis...

The Decomposition of Deformation: new metrics to enhance shape analysis in medical imaging.
Medical image analysis experienced, in the last two decades, a significant boost in both shape recognition from medical images and analysis of related geometric data. In particular, 2D and 3D Speckle Tracking Echocardiography (2D and 3D STE), CT-scan and Magnetic Resonance (MR) represented the most used technologies, albeit not unique, in order to extract anatomical shapes from medical images to be analyzed and evaluated in terms of form, function and, ultimately, physiology. Shapes are identified by points (=landmarks) in 2D/3D space.

Zebra Medical Vision wins FDA nod for Coronary Calcium Scoring algorithm
Israeli machine-learning radiology firm Zebra Medical Vision said this week it won FDA 510(k) clearance for its Coronary Calcium Scoring algorithm. The company said the algorithm is designed to automatically calculate a patient’s Agatston equivalent coronary calcium score from ECG gated CT scans to improve assessments of patients at risk for coronary artery disease. “Identification of high-risk individuals is key to prevention Zebra’s algorithm could run on CT studies of the chest and potentially help identify people with cardiovascular risk sooner, allowing more effective treatment and overall reduction of ...

Reducing the Hausdorff Distance in Medical Image Segmentation With Convolutional Neural Networks
The Hausdorff Distance (HD) is widely used in evaluating medical image segmentation methods. However, the existing segmentation methods do not attempt to reduce HD directly. In this paper, we present novel loss functions for training convolutional neural network (CNN)-based segmentation methods with the goal of reducing HD directly. We propose three methods to estimate HD from the segmentation probability map produced by a CNN. One method makes use of the distance transform of the segmentation boundary. Another method is based on applying morphological erosion on the difference between the true and estimated segmentation m...

Multi-Modal Deep Guided Filtering for Comprehensible Medical Image Processing
Deep learning-based image processing is capable of creating highly appealing results. However, it is still widely considered as a “blackbox” transformation. In medical imaging, this lack of comprehensibility of the results is a sensitive issue. The integration of known operators into the deep learning environment has proven to be advantageous for the comprehensibility and reliability of the computations. Consequently, we propose the use of the locally linear guided filter in combination with a learned guidance map for general purpose medical image processing. The output images are only processed by the guided...
