Abstract
Abstract Structural and functional imaging of the pancreas can be achieved with magnetic resonance imaging and a secretin solution. An amount of secretin is placed in solution and administered to a patient for the purpose of pancreatic imaging. Because the secretin solution changes the signal intensity of the pancreas, it can be imaged relative to baseline fasting studies for the purposes of tumor detection and qualification of exocrine dysfunction.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
109 words
A method of magnetic resonance imaging of the pancreas in a patient comprising the steps of: administering a predetermined dose from a stock solution containing one of a group comprised of recombinant human secretin, recombinant porcine secretin, recombinant bovine secretin, natural bovine, and natural porcine secretin; waiting a predetermined period of time in the range of one to thirty minutes to permit distribution of the solution throughout the patient; subjecting the pancreas to magnetic resonance imaging by a magnetic resonance imaging machine having at least a 1 T magnet within said predetermined period of time; and observing a T 2 -weighted image to produce an image of the pancreas.
Claim 2
Independent Claim
109 words
A method of magnetic resonance imaging of the pancreas in a patient comprising the steps of: administering a predetermined dose from a stock solution containing one of a group comprised of recombinant human secretin, recombinant porcine secretin, recombinant bovine secretin, natural bovine, and natural porcine secretin; waiting a predetermined period of time in the range of one to thirty minutes to permit distribution of the solution throughout the patient; subjecting the pancreas to magnetic resonance imaging by a magnetic resonance imaging machine having at least a 1 T magnet within said predetermined period of time; and observing a T 2 -weighted image to produce an image of the pancreas.
Claim 3
Dependent Claim
29 words
The method of magnetic resonance imaging as set forth in claim 1 further comprising before said administering step, the step of determining a base line image of said patient.
Claim 4
Dependent Claim
30 words
The method of magnetic resonance imaging of claim 1 wherein said predetermined dose is administered having a ratio of 2 clinical units per kilogram of body weight of the patient.
