Project description

Liver cancer is the sixth most common cancer in the world but is the second most frequent cause of cancer death in men and the sixth leading cause of cancer death in women. Among the different types of liver cancer, hepatocellular carcinoma (HCC) can be treated by selective internal radiation therapy (SIRT), which consists in injecting selectively into the hepatic arteries yttrium-90 (Y90) β-radiation emitter microspheres. Prior to Y90 bead injection, several examinations must be performed. First, a hepatic angiography is acquired to identify the extrahepatic vessels that must be prophylactically embolized to preserve healthy organs, and a baseline contrast­enhanced magnetic resonance imaging (ceMRI) scan is acquired to visualise the tumour. Then, a simulation of the treatment is performed by injecting Technetium-99m macroaggregated albumin (Tc99m-MAA) as a surrogate for Y90 particles. A pre-treatment dosimetry is performed by acquiring a single-photon emission computed tomography (SPECT)/computed tomography (CT) scan which allows to obtain the Tc99m-MAA distribution of activity and to calculate the Y90 activity to prescribe. Once calculated, the appropriate amount of Y90 microspheres is injected into the patient and a positron emission tomography (PET)/CT scan is acquired to verify that the Y90 activity distribution is consistent with the simulation of the treatment and to perform post-treatment dosimetry. To be able to compute a proper dosimetry, it is necessary beforehand to perform registrations and delineate accurately the tumour and liver volumes. The aim of this PhD is first to perform registrations between the baseline ceMRI and SPECT/CT images (pre-treatment dosimetry), and between the baseline ceMRI and the PET/CT images (post-treatment dosimetry) and then to bring state-of-the-art deep learning segmentation methods to SIRT to segment the liver and tumour volumes. The objective of the registration work is not to develop a new registration method, neither a new tool, but rather to validate/optimise on our data existing approaches already implemented in software packages such as NiftyReg ( or elastix ( The PhD student will be helped in this task by a trainee. The objective of the segmentation work is to develop two supervised deep learning segmentation algorithms. A first supervised deep learning segmentation method that takes advantage of the MRI structural information only (baseline ceMRI) and a second supervised co-segmentation method that takes advantages of both the SPECT/CT and the baseline ceMRI images.

The student will be located at the ImViA laboratory and will work in close relation with the medical teams of the University Hospital François Mitterrand and the Georges François Leclerc Centre both in Dijon, France.
