About this trial
This study's purpose is the comparison of the automatically segmented 3D model to the reference manual segmentation, based on the Dice precision index. It is implemented by making parents' patients, surgeons and surgical helpers answer specific questions comparing 3D images to usual 2D images of the patient's tumor.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers

Disqualifiers
Contraindication to MRI: metallic ocular foreign body, pacemaker, mechanical heart valve, old vascular clips on cerebral aneurysm
Need for an MRI under general anaesthesia
Contraindication for a CT scan with injection: renal failure, allergy to iodinated contrast products
Patients having participated in a therapeutic clinical trial involving a new molecule within 30 days before inclusion
Trial population
Children with a pelvic or retroperitoneal tumor requiring an MRI or CT scan for a possible surgical intervention coming at the hospital for a consultation as part of their standard care.

Trial outcomes
Primary outcomes
Segmentation comparison
Comparison of the automatically segmented 3D model to the reference manual segmentation, based on the Dice precision index
