Dear Advanced Visualization Insider,
With the American Board of Radiology core exam just a few weeks away, studying and skills improvement are top of mind for many radiology residents. A number of web-based tools are available to help, including AuntMinnie.com’s own Board Review as well as a new application designed to help users improve their ability to detect lung nodules on chest x-rays.
A group from Europe developed a deep-learning model for lung segmentation and combined it with an AI algorithm for generating artificial lung nodules. Their web-based application, called Perception Trainer, can then simulate lesions on top of previous imaging studies. You can learn all about it by clicking here.
Another new study found that CT radiomics features extracted from abdominal fat and muscle tissue can help predict early recurrence of liver cancer after surgery. Pre- and postoperative nomograms incorporating radiomics enabled hepatocellular carcinoma patients to be risk-stratified for early recurrence, according to the researchers.
Speaking of radiomics, a deep learning-based radiomics model was deemed to be useful for differentiation of complicated and uncomplicated acute appendicitis. The authors believe that their approach could help improve patient selection for nonoperative management.
What’s more, a PET radiomics model developed by a group from the Netherlands was able to predict disease-free survival odds in patients with relapsed or refractory classical Hodgkin's lymphoma.
Meanwhile, a team from the University of Texas Southwestern Medical Center in Dallas reported that 3D anatomic models can be produced cost-effectively for planning pediatric surgeries. The group's low-cost method facilitated the creation of 3D models that could be exported in formats conducive to 3D printing, visualization in virtual reality, or as an anatomic reference during the perioperative period, according to the researchers.
