Postmortem CT, 3D touchscreen table aid virtual autopsy
 June 14, 2013 -- Postmortem CT can be an invaluable autopsy planning tool. With the help of a life-sized, 3D-enabled touchscreen table, pathologists can also view and manipulate images in 3D modes to locate pathology, perform virtual dissections, and decide on the best autopsy approach.
Imaging experts mull over color challenges
 May 28, 2013 -- Color images are technically difficult to deal with, creating a thorny issue that's growing as PACS broadens from radiology and cardiology to include other specialties that use color-heavy images. Medical informatics expert Dr. David Clunie discusses a recent meeting designed to provide a framework for handling color.
CAD for breast MRI improves sensitivity; accuracy not so much
 May 24, 2013 -- Computer-aided detection (CAD) technology improves sensitivity in breast MRI for both experienced and novice readers, but it does not significantly advance overall accuracy, according to a study published in the June issue of the American Journal of Roentgenology.
CAD helps detect and treat skull fusion in infants
 May 20, 2013 -- Computer-aided detection (CAD) technology can be an invaluable tool for quantitative diagnosis and treatment planning of craniosynostosis, or premature fusion of skull sutures in infants, researchers from Children's National Medical Center in Washington, DC, have found.
4D musculoskeletal CT offers window into joint disorders
 May 17, 2013 -- There's still a lot to learn about how bones interact in joints during movement, but 4D musculoskeletal CT can help close that knowledge gap, paving the way for new understanding of joint disorders and how to treat them, according to researchers from Monash Health Centre in Melbourne, Australia.
Volumetric MR images boost cervical cancer treatment planning
 May 13, 2013 -- Three-dimensional volumetric MR images of cervical disease yield a bounty of critical information, enabling precise planning of brachytherapy for residual tumors, according to researchers from St. Joseph's Hospital and Medical Center in Phoenix.
CAD, bone suppression find more lung nodules on chest x-ray
May 7, 2013 -- At the cost of more false positives, the combination of computer-aided detection (CAD) and electronic bone suppression can help radiologists improve detection rates for pulmonary nodules on chest radiographs, according to research published in the May issue of the American Journal of Roentgenology.
Curved MIPs aid detection of thin intracranial hematomas
 May 1, 2013 -- An advanced visualization technique utilizing curved maximum intensity projections (MIPs) that parallel the inner table of the skull may be able to significantly improve sensitivity for detecting thin epidural and subdural hematomas, according to an Austrian article published in Radiology.
Radiologists prefer CAD with fewer clicks
April 24, 2013 -- Radiologists prefer computer-aided detection (CAD) software that gives them necessary information with the fewest clicks possible and is closely integrated with PACS, rather than applications that require multiple manual steps to interrogate data, according to a team of German researchers.
Breast CAD's effectiveness questioned again in new study
April 15, 2013 -- Dr. Joshua Fenton of the University of California, Davis has emerged as one of the most prominent skeptics of computer-aided detection (CAD) technology for breast screening. Fenton is again questioning CAD's effectiveness in a new study published online April 15 in the Annals of Internal Medicine.
Advanced CT reconstruction improves cardiac plaque assessment
 April 12, 2013 -- Automated plaque assessment in coronary CT angiography is a promising new way to evaluate a patient's plaque burden quickly and noninvasively -- but it won't be quick or accurate without the use of advanced iterative reconstruction, according to researchers from Massachusetts General Hospital in Boston.
CT postprocessing can aid evaluation of pediatric airways
April 1, 2013 -- Because it's noninvasive and doesn't require anesthesia, CT postprocessing offers significant advantages over the gold standard of bronchoscopy for evaluating pediatric airways. Yet there are even more benefits, according to an article published recently in Pediatric Radiology.
Software saves time in quantifying pleural effusions on MDCT
 March 27, 2013 -- A software tool can swiftly and accurately perform semiautomated volumetric quantification of pleural effusions on MDCT studies, yielding significant time savings over manual quantification methods, according to researchers from Northwestern University.
MRI spots brain abnormalities in patients with migraines
 March 26, 2013 -- Using a surface-based MRI method to measure cortical thickness, Italian researchers have found that migraine headaches may be related to brain abnormalities present at birth and other abnormalities that develop over time, according to a study published online in Radiology.
Automated postprocessing tools improve cardiac MR scans
 March 21, 2013 -- Several image postprocessing methods are up for the task of assessing myocardial scar tissue from late gadolinium enhancement on cardiac MR exams, according to a multicenter study presented at the recent Society for Cardiovascular Magnetic Resonance meeting.
Ultrasound CAD aids in characterizing breast lesions
 February 6, 2013 -- Ultrasound computer-aided detection (CAD) technology can improve reader accuracy and diagnostic confidence for distinguishing between benign and malignant breast lesions, according to Japanese researchers.
NIH software makes PET/MRI image analysis easier
 January 21, 2013 -- Lesion segmentation on PET/MRI studies can be challenging, but a team from the U.S. National Institutes of Health (NIH) has developed a software application that automates the process, making it easier for clinicians to identify boundaries between disease and healthy tissue.
Kinect suitable for surgical manipulation of MR images
January 14, 2013 -- Microsoft's Kinect motion-sensing gaming device is reliable for surgeons to use to manipulate MR images on operating room workstations, according to research from the Purdue University Department of Industrial Engineering.
Prostate cancer CAD requires zone-specific techniques
 January 10, 2013 -- Location is everything. If recent research results are any indication, that old real-estate maxim also appears true for applying computer-aided detection (CAD) technology to the detection of prostate cancer.
New technologies drive Medicare breast screening costs higher
January 7, 2013 -- Medicare costs for breast screening are being driven higher by new technologies such as digital mammography and computer-aided detection, which are being adopted in spite of limited data on their effectiveness, according to a study published on Monday in JAMA Internal Medicine.
