Liver Radiology Key
This work presented the development of an automatic method for liver and tumor segmentation from CT scans. The proposed method was based on fully convolutional neural (FCN) network with region-based level set function. The framework starts to segment the liver organ from CT scan, which is followed by a step to segment tumors inside the liver.

We aim to develop and validate a three-dimensional convolutional neural network (3D-CNN) model for automatic liver segment segmentation on MRI images. Methods This retrospective study evaluated an automated method using a deep neural network that was trained, validated, and tested with 367, 157, and 158 portal venous phase MR images, respectively.

Dataset. The 3D-IRCADb-01 database is composed of three-dimensional (3D) CT-scans of 20 different patients (10 females and 10 males), with hepatic tumors in 15 of those cases. Each image has a resolution of 512 × 512 width and height. The depth or the number of slices per patient ranges between 74 and 260.

Fully Automated Measurements of Liver Segments and Spleen Volume. Two DL models developed in-house were used to automatically segment the eight liver Couinaud segments and spleen from a CT volume. Details of the training data and model development are provided in Appendix E1 (supplement). The outputs of the models include the segmentation.

Each segment has its own pulmonary arterial branch and thus, the bronchopulmonary segment is a portion of lung supplied by its own bronchus and artery. Each segment is functionally and anatomically discrete allowing a single segment to be surgically resected without affecting its neighboring segments. There is some form of segmental symmetry.

segment 1 (I) is the caudate lobe bounded posterolaterally by the fossa for the inferior vena cava, anteriorly by the ligamentum venosum, and inferiorly by the porta hepatis its inferior portion is subdivided into a lateral caudate process and a medial papillary process 6 may receive its supply from both the right and the left portal vein

The level set segmentation uses an initial user-defined liver segment in one slice, and then segments the liver through all other slices, using a Gaussian fit to define the speed image where the level sets propagates..

Finally, the Couinaud anatomical segments are identified according to the anatomical liver model proposed by Couinaud. Results: Experiments were conducted using data and metrics brought from the liver segmentation competition held in the Sliver07 conference. A subset of five exams was used for estimation of segmentation parameter values, while.

A liver segment is one of eight segments of the liver as described in the widely used Couinaud classification (named after Claude Couinaud) in the anatomy of the liver.
