Odds are good: MRI with MRCP is quite sensitive and specific. There is limited head to head data regarding to the two techniques of MRI/MRCP and EUS - though MRI/MRCP is less invasive and less operator dependent. As a side note, there is data available that suggests MRI/MRCP has a sensitivity and specificity of in the 80's and high 90's(percentage wise) respectively. Reasonably good numbers. Best of luck.

Pancreatic cancer: Was the CT tailored for pancreatic mass protocol? If so it is highly accurate for detecting even very small panc masses. If it was a routine CT, the accuracy is still high, but very small tumors may not be seen. MRCP is also not specifically tailored to look for panc mass, so very small lesions may not be seen. No test is 100%, so it is always possible that another test could pick something up.

EUS- smaller lesions: CT scan, angiogram, and MRI can often miss pancreatic tumors less than 2cm in diameter.EUS can find tumors that are smaller than 3mm.Biopsies can also be obtained with an EUS. EUS can also suggest if a pancreatic cyst is malignant or not.An MRCP can give very high quality images of the pancreas, the pancreas duct, and the bile ducts. If you haven't already, you might want to go ahead with the EUS.

If it is tailored: For liver mass, and technically adequate(i.e. no artifacts that might obscure anatomy), it would be nearly impossible to miss a large liver tumor.
