Artificial Intelligence

Artificial intelligence (AI) is becoming a crucial component of healthcare to help augment physicians and make them more efficient. In medical imaging, it is helping radiologists more efficiently manage PACS worklists, enable structured reporting, auto detect injuries and diseases, and to pull in relevant prior exams and patient data. In cardiology, AI is helping automate tasks and measurements on imaging and in reporting systems, guides novice echo users to improve imaging and accuracy, and can risk stratify patients. AI includes deep learning algorithms, machine learning, computer-aided detection (CAD) systems, and convolutional neural networks.

You’ve never seen fruit like this

Taking a break from imaging patients, an MRI technologist from Boston University Medical School took scans of a variety of fruits and vegetables. The images produced are worth a look.

NovoPath Debuts Web Portal for Patient Access to Test Result Reports

NovoPath introduces a customizable web portal to its NovoPath anatomic pathology laboratory information system (APLIS), helping customers efficiently comply with new legislation requiring labs to provide direct patient access to reports.  The new feature enables patients with test results to log on to a web portal through a lab’s website and download the documents generated through NovoPath’s APLIS.

Transarterial chemoembolization, sorafenib are one powerful pair

Combining transarterial chemoembolization with sorafenib in treating patients with hepatocellular carcinoma and portal vein tumor thrombus could improve overall survival rates, according to a study published online April 6 by Radiology.

Studies back coronary CTA, and other recent research

A summary of trends in cardiac CT presented last month at the American College of Cardiology scientific session in Washington, D.C., provided an opportunity for a victory lap of sorts for coronary CT angiography (CTA) in the emergency department.

New dose measurement technique applicable to CT colonography

A new in vivo radiation dose measurement technique can be applied to patients undergoing CT colonography (CTC), according to a study published in the April issue of the American Journal of Roentgeonlogy. 

Radiology device recalls on the rise

Radiology device recalls significantly increased from 2003 to 2012, according to the Medical Device Recall Report that was published by the Food and Drug Administration (FDA) on March 21. 

Potholes in the imaging road: Analysis could introduce bias in mild TBI diagnosis

The previously reported diagnostic performance of diffusion-tensor imaging (DTI) for mild traumatic brain injuries (TBIs) could be called into question due to bias introduced by the pothole approach to neuroimaging data, according to a study published online March 14 by Radiology. 

CAD improves lung nodule detection

Computer-aided detection (CAD) has demonstrated an ability to improve the performance of radiologists in detecting lung nodules on chest radiographs, according to a study published online March 12 by Radiology. 

Around the web

A total of 16 cardiology practices from 12 states settled with the DOJ to resolve allegations they overbilled Medicare for imaging agents used to diagnose cardiovascular disease. 

CCTA is being utilized more and more for the diagnosis and management of suspected coronary artery disease. An international group of specialists shared their perspective on this ongoing trend.

The new technology shows early potential to make a significant impact on imaging workflows and patient care.
