AI can yield patient-specific radiation dose estimates
June 22, 2017 -- A machine-learning algorithm shows potential for facilitating the holy grail of real-time, patient-specific radiation dose estimates from CT scans, according to research presented at the Society for Imaging Informatics in Medicine annual meeting earlier this month in Pittsburgh.
ISCT: Who's responsible for radiology's value chain?
June 8, 2017 -- SAN FRANCISCO - In a healthcare environment characterized by tight resources -- and, at least until recently, a shift from volume- to value-based care payment models -- who should be responsible for radiology's value chain: the department or the hospital?
ISCT: The long road to full automation in abdominal CT
June 7, 2017 -- SAN FRANCISCO - The past few years have seen rapid progress toward the goal of automated abdominal CT analysis using multiple computer-aided-detection systems, all theoretically applied to a single abdominal CT angiography dataset, according to a Tuesday presentation at the International Society for Computed Tomography (ISCT) symposium.
ISCT: Ultrahigh-resolution CT raises the bar
June 6, 2017 -- SAN FRANCISCO - Exquisitely detailed ultrahigh-resolution CT is on its way thanks to several technologies, although most haven't reached the market yet, according to a talk on Monday at the International Society for Computed Tomography (ISCT) meeting.
ISCT: Will cinematic rendering become '3D on steroids'?
June 6, 2017 -- SAN FRANCISCO - A new data reconstruction technique called cinematic rendering that creates photorealistic images was discussed in a Monday session at the International Society for Computed Tomography (ISCT) symposium. The technique is like "3D on steroids," according to Dr. Elliot Fishman, who is testing it at Johns Hopkins University.
ISCT: Value of CT depends on who's looking
June 5, 2017 -- SAN FRANCISCO - Gauging the value of a CT scan is the single most critical reason for deciding whether to perform an exam. But when you get down to it, value depends on what you're looking for and who's looking at it, according to talks on Sunday at the International Society for Computed Tomography (ISCT) annual meeting.
CT detects frailty and predicts survival in elderly
June 2, 2017 -- CT scans are going beyond identifying broken bones to detecting skeletal frailty in the elderly, and even predicting their ability to survive a fall, according to a study in the June edition of the American Journal of Roentgenology.
ACR 2017: Radiation dose varies in head CTs of children
May 23, 2017 -- A large analysis of pediatric head CT scans across the U.S. showed surprisingly large variations in radiation dose that increased as children grew older, according to results presented at this week's American College of Radiology (ACR) meeting in Washington, DC.
Deep learning for lung cancer advances goals
May 11, 2017 -- SAN JOSE, CA - Deep-learning algorithms based on convolutional neural networks are advancing a number of cherished goals in lung cancer analysis that will soon help patients live longer -- and even predict how long they might expect to live, according to a May 10 talk at the NVIDIA GPU Technology Conference.
Ottawa Hospital slashes lung cancer treatment time
May 8, 2017 -- What's the best way to reduce time to treatment for patients with abnormal CT scans who are referred for suspected lung cancer? The radiology department at a Canadian hospital was able to cut the time to treatment in half for referred patients, according to a presentation at last month's Canadian Association of Radiologists meeting in Montreal.
