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 volunteers

Qualifiers

Children between 3 months and less than 18 years old

Children with a pelvic tumor requiring an MRI for a possible surgical intervention

Children with a retroperitoneal tumor requiring a CT scan or MRI with a view to surgical intervention

Children with no contraindication for a CT scan and/or 3T MRI

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.
