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

1. 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.)
2. general diagnostic category (e.g., neoplasm, infection, etc.)
3. 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.
