ABSTRACTBackground & AimsWhether large language models (LLMs) could be integrated into the diagnostic workflow of focal liver lesions (FLLs) remains unclear. We aimed to investigate two generic LLMs (ChatGPT‐4o and Gemini) regarding their diagnostic accuracies referring to the CT/MRI reports, compared to and combined with radiologists of different experience levels.MethodsFrom April 2022 to April 2024, this single‐center retrospective study included consecutive adult patients who underwent contrast‐enhanced CT/MRI for single FLL and subsequent histopathologic examination. The LLMs were prompted by clinical information and the “findings” section of radiology reports three times to provide differential diagnoses in the descending order of likelihood, with the first considered the final diagnosis. In the research setting, six radiologists (three junior and three middle‐level) independently reviewed the CT/MRI images and clinical information in two rounds (first alone, then with LLM assistance). In the clinical setting, diagnoses were retrieved from the “impressions” section of radiology reports. Diagnostic accuracy was investigated against histopathology.Results228 patients (median age, 59 years; 155 males) with 228 FLLs (median size, 3.6 cm) were included. Regarding the final diagnosis, the accuracy of two‐step ChatGPT‐4o (78.9%) was higher than single‐step ChatGPT‐4o (68.0%, p < 0.001) and single‐step Gemini (73.2%, p = 0.004), similar to real‐world radiology reports (80.0%, p = 0.34) and junior radiologists (78.9%–82.0%; p‐values, 0.21 to > 0.99), but lower than middle‐level radiologists (84.6%–85.5%; p‐values, 0.001 to 0.02). No incremental diagnostic value of ChatGPT‐4o was observed for any radiologist (p‐values, 0.63 to > 0.99).ConclusionTwo‐step ChatGPT‐4o showed matching accuracies to real‐world radiology reports and junior radiologists for diagnosing FLLs but was less accurate than middle‐level radiologists and demonstrated little incremental diagnostic value.

Percutaneous recanalization of non-cirrhotic extrahepatic portal vein obstruction in children: technical considerations in a preliminary cohort

Abstract Objectives Portal hypertension resulting from non-cirrhotic extrahepatic portal vein obstruction (EHPVO) in children has been primarily managed with the Meso-Rex bypass, but only a few patients have a viable Rex recessus, required by surgery. This study reports a preliminary series of patients who underwent interventional radiology attempts at portal vein recanalization (PVR), with a focus on technical aspects and safety. Methods A retrospective review of consecutive patients with severe portal hypertension due to non-cirrhotic EHPVO at a single institution from 2022, who underwent percutaneous attempts at PVR, was performed. Technical and clinical data including fluoroscopy time, radiation exposure, technical and clinical success, complications and follow-up were recorded. Results Eleven patients (6 males and 5 females; median age 7 years, range 1–14) underwent 15 percutaneous transhepatic (n = 1), transplenic (n = 11), or simultaneous transhepatic/transplenic (n = 3) procedures. Rex recessus was patent in 4/11 (36%). Fluoroscopy resulted in a high median total dose area product (DAP) of 123 Gycm2 (range 17–788 Gycm2) per procedure. PVR was achieved in 5/11 patients (45%), 3/5 with obliterated Rex recessus. Two adverse events of grade 2 and grade 3 occurred without sequelae. After angioplasty, 4/5 patients required stenting to obtain sustained patency, as demonstrated by colour-Doppler ultrasound in all PVR after a median follow-up of 6 months (range 6–14). Conclusion Our preliminary experience suggests that 45% of children with non-cirrhotic EHPVO can restore portal flow even with obliterated Rex recessus. In non-cirrhotic EHPVO, PVR may be an option, if a Meso-Rex bypass is not feasible, although the radiation exposure deserves attention. Clinical relevance statement Innovative percutaneous procedures may have the potential to be an alternative option to the traditional surgical approach in the management of non-cirrhotic EHPVO and its complications in children not eligible for Meso-Rex bypass surgery. Key Points Non-cirrhotic portal hypertension in children has been traditionally managed by surgery with Meso-Rex bypass creation. Percutaneous PVR may restore the patency of the native portal system even when the Rex recessus is obliterated and surgery has been excluded. Interventional radiological techniques may offer a minimally invasive solution in complex cases of EHPVO in children when Meso-Rex bypass is not feasible.
