PitVQA-Anticipation dataset with images and question-answer pairs
Listed in figshare
<p dir="ltr"><b>PitVQA-Anticipation</b> is a visual question-answering dataset for forward-looking reasoning in endoscopic pituitary surgery.
Description
It is derived from 25 surgical videos recorded at the National Hospital for Neurology and Neurosurgery in London, United Kingdom. The procedures were recorded using a high-definition Karl Storz endoscope at 720p resolution and comprise approximately 33.5 hours of operative video.
Frames were extracted at 1 frame per second, with blurred or occluded frames removed, resulting in 109,173 usable frames.Each frame is associated with exactly seven question–answer pairs covering four anticipation tasks: forecasting future surgical phases, predicting the next operative step, identifying instruments required for the next step, and estimating the remaining duration of the current step, current phase and complete procedure.

The full frame-level dataset contains 764,211 question–answer pairs. Its target annotations cover 39 categories, comprising 4 future phases, 14 future steps, 18 instruments and 3 remaining-time targets.The source videos were annotated by two neurosurgical residents with experience in pituitary surgery and reviewed by an attending neurosurgeon. According to the source dataset documentation, all patients provided informed consent and the study was registered with the local governance committee.<br><br><b>Acknowledgement</b></p><p dir="ltr"><br></p><ul><li>PitVQA images are derived from MICCAI PitVis challenge:</li><li>PitVis Paper: arxiv.org/abs/2409.01184</li><li>PitVis Challenge: synapse.org/Synapse:syn51232283</li><li>PitVis Dataset: doi.org/10.5522/04/26531686</li></ul><p><br></p><p><br></p><p dir="ltr">If you use this code for your research, please cite our paper.</p><p dir="ltr">doi.org/10.1007/s11548-026-03784-z</p>
