Dear Imaging Informatics Insider,
For all the progress that has been made in PACS technology, there is always room for improvement. Indeed, PACS software developers still need to address important technological limitations that can have a negative impact on user experience, according to researchers from the U.K. and Kuwait.
After monitoring and analyzing posts in several online PACS discussion groups over a two-year period, the researchers concluded that the current generation of PACS has a number of limitations, including issues with storage, the number of windows on PACS workstations, and integrating PACS from different vendors. Click here for their opinions on how these and other PACS problems could be addressed.
The difficulty in gathering large, well-curated datasets is one of the big challenges in training artificial intelligence (AI) algorithms for imaging applications. An AI algorithm that can produce synthetic abnormal images could help solve that problem, however. Recent research found that synthetic brain MR images could be utilized to augment a small dataset or even used on their own to train a deep-learning model. Click here to learn more.
Speaking of AI, Swiss researchers have determined that an AI algorithm can be highly sensitive and specific for identifying acute findings on abdominal CT scans, enabling radiologists to prioritize reading these urgent exams. Click here for all the details on this workflow triage application.
In other news, AI can predict how cancer patients will respond to immunotherapy by analyzing a radiomic-based biomarker on CT scans, according to French researchers. Click here to access our report.
AI is often overhyped, though, says Dr. Paul McCoubrie of Southmead Hospital in Bristol, U.K., in an update to his popular "20 golden rules of radiology" articles on AuntMinnieEurope.com. What else is on his list of new golden rules for radiology? Click here to find out.
Bad or unethical use of AI in radiology could be dangerous, and Italian researchers believe that regulation is needed to ensure AI is used safely, ethically, and appropriately with protection of patient privacy. Patients, radiologists, and regulatory authorities will have to collaborate to accomplish this goal, according to the researchers. Click here for our coverage of their analysis.

![Examples of ultrasound findings and techniques. (A) Images in a 39-year-old male patient with a mass in the left thigh. The mass is heterogeneous on the B-mode US image (compared with the patient in D) and showed increased microvascularity (superb microvascular imaging [SMI]) and shear-wave elastography (SWE) values. Undifferentiated pleomorphic sarcoma was diagnosed at biopsy (with pleomorphic rhabdomyosarcoma in surgical specimen). (B) Images in an 18-year-old male patient with a mass in the left leg. The mass is hypoechoic on the B-mode image, with no other findings suggestive of malignancy. The lesion is in contact with the cortex of the tibia, which is slightly irregular. CT revealed a doubtful anteromedial tibial erosion. The microvascular study demonstrated high vascularization, suggestive of malignancy. Periosteal Ewing sarcoma was diagnosed with both histologic and immunohistochemical confirmation. (C) Images in a 69-year-old female patient with a lump growing on the outside of the left leg. Multiple SWE examinations were performed (please note the high values obtained in the measurements, whereas the color map highlights the stiffness relative to adjacent tissues). SMI showed areas of increased vascularization to target for sampling. Undifferentiated spindle cell sarcoma was diagnosed at biopsy, with residual leiomyosarcoma in the surgical specimen after neoadjuvant therapy. (D) Images in a 56-year-old female patient with a mass in the right thigh. The mass is heterogeneous at both B-mode ultrasound (similar to patient A) and MRI (coronal T2-weighted spectral attenuated inversion recovery [SPAIR]; T1-weighted pre-contrast and postcontrast imaging), which even shows uptake after the administration of paramagnetic contrast material, which is traditionally suggestive of malignancy. Low values at SMI and elastography are suggestive of benignity. Spindle cell lipoma was diagnosed at biopsy, with atypical spindle cell lipomatous tumor in the surgical specimen.](https://img.auntminnieeurope.com/mindful/smg/workspaces/default/uploads/2026/08/images-radiol250278fig2.APCFLSvX6p.jpg?auto=format%2Ccompress&fit=crop&h=100&q=70&w=100)
