Abstract

The invention provides an image sequence display method based on a liver MR examination purpose. Comprising the following steps: establishing a corresponding relation between a liver MR scanning clinical purpose and sequence diagnosis information (including an MR image sequence and / or a diagnosis thought), determining the sequence diagnosis information corresponding to the clinical purpose based on the corresponding relation, and calling and displaying the sequence diagnosis information; the invention further provides a system for implementing the method. According to the method and the system, the optimized display sequence of all MR sequences can be specifically given based on the liver MR examination purpose, diagnosis ideas corresponding to the sequences can be provided for reference of doctors, the working process can be optimized, the report writing and diagnosis efficiency of the diagnosis doctors can be improved, and the method and the system have good popularization and application prospects.

Description

technical field [0001] The invention belongs to the field of medical information, and in particular relates to an image sequence display method and system based on the purpose of liver MR examination. Background technique [0002] The incidence of liver disease in my country is relatively high, and common liver diseases include diffuse liver disease (fatty liver, hepatic iron deposition, liver cirrhosis, etc.) and focal liver disease (benign liver tumor, liver malignant tumor, liver metastases, etc.). Magnetic resonance imaging (MRI) is one of the important means of diagnosing liver diseases. [0003] In the process of MRI imaging, different images can be obtained by changing the influencing factors of magnetic resonance (MR) signals, and these different images are called sequences. Applicable liver enhanced scanning scheme usually includes: 1. Position image; 2. Coronal T 2 WI, transverse position T 2 WI; 3. Inverse phase; 4. Magnetic resonance cholangiopancreatography (...
