Outcome measures
Primary outcome
Primary endpoint is the number of patients in whom a connection between the pancreatic cyst and PD can be visualized with increased certainty on 3.0T compared with 1.5T MRI/MRCP, evaluated by an experienced radiologist using a 5-point scale:
1: no connection PD
2: unlikely connection PD
3: undetermined connection PD
4: likely connection PD
5: clear connection PD
Secondary outcome
1. Change in follow-up or treatment strategy according to the current guidelines (International Association of Pancreatology (IAP) and European Cystic Tumor Study Group.
2. Visualization of worrisome features with 3.0T compared with 1.5T MRI/MRCP:
‐ Mural nodules
‐ Thickened/enhancing cyst walls
3. Difference in cyst morphology on 3.0T compared with 1.5T MRI/MRCP:
‐ Lobulation
‐ Pleomorphism
4. Amount of artefacts, evaluated by using a 3-point scale:
- 1: artefacts causing difficulties evaluating images
- 2: minor/moderate artefacts without diagnostic relevance
- 3: (almost) no artefacts
5. Interobserver agreement: intraclass correlation coefficient (ICC) values higher than 0.8 are considered to be excellent concordance, values between 0.6 and 0.8 as good, values between 0.4 and 0.6 as moderate, values between 0.2 and 0.4 as fair and values below 0.2 as poor
Background summary
Rationale: Distinction between the different types of pancreatic cysts is crucial, since some cysts are benign without need for follow-up, whereas others are premalignant and require either surgical resection or surveillance. A key feature of the most common premalignant cyst, the side branch-intraductal papillary mucinous neoplasm (SB-IPMN), is the presence of a connection between the cyst and the pancreatic duct (PD). Current imaging, mostly done with 1.5T MRI/MRCP, is often not capable of visualizing this connection. Recent, small studies have suggested that 3.0T MRI/MRCP can provide superior image quality with improved delineation of the PD, but prospective studies in patients with pancreatic cysts are lacking. We hypothesize that 3.0T MRI/MRCP might be more accurate in visualizing a connection between a pancreatic cyst and the PD than 1.5T MRI/MRCP.
Objective: Primary objective is to compare the diagnostic ability of 3.0T and 1.5T MRI/MRCP in visualizing PD communication of pancreatic cysts. Second objectives are to compare the presence of mural nodules and thickened cyst wall and the amount of artefacts.
Study design: Prospective consecutive cohort of 20 patients.
Study population: Consecutive adult patients of the multidisciplinary pancreatic cyst clinic who are under follow-up for at least one pancreatic cyst in which no clear or likely connection with the PD has been seen on previous 1.5T MRI/MRCP and without classic features of a serous/mucinous cystic neoplasm.
Intervention: 3.0T MRI/MRCP during routine follow up of pancreatic cysts
Main study parameters/endpoints: Primary endpoint is the number of patients in whom a connection between the pancreatic cyst and PD can be visualized with 3.0T, whereas 1.5T MRI/MRCP could not.
Study objective
We hypothesize that 3.0T MRI/MRCP might be more accurate in visualizing a connection between a pancreatic cyst and the PD than 1.5T MRI/MRCP.
Study design
One 3.0T MRI/MRCP will be made during routine follow-up.
Intervention
Patients who are planned to undergo surveillance with MRI/MRCP will undergo 3.0T MRI/MRCP with contrast (gadovist) instead of 1.5T MRI/MRCP with gadovist. Imaging features of 3.0T MRI/MRCP and previously made 1.5T MRI/MRCP will be compared.
