The Liver Imaging Atlas Users Manual
The Liver Imaging Atlas is a collection of CT, MR, and ultrasound cases that demonstrate common and uncommon liver pathologies.
Each case is categorized by
- morphologic features - which are further subdivided into structural features - those characteristics that are frequently the same on different imaging modalities (e.g., infiltrative pattern of growth) - and imaging features - those characteristics that may be specific to a imaging modality (e.g., high signal intensity on T2w sequences, enhancing septations, etc.)
- general diagnostic category (e.g., neoplasm, infection, etc.)
- diagnosis (or diagnoses).
Organization of liver disease by its imaging characteristics is a unique feature of this atlas that can be useful to the radiologist analyzing an unknown liver condition or lesion. A search of the atlas performed by selecting specific imaging features will retrieve a list of cases and diagnoses that share imaging features.
Alternatively, performing a search of the atlas by diagnosis or by diagnostic category will retrieve cases to illustrate the spectrum of imaging features within a specific diagnosis or diagnostic category.
The information obtained from such searches could help a radiologist analyze an unknown liver lesion and construct an image-based differential diagnosis.
Following the links in the table of contents to the left will provide additional information on how to use the atlas.
