Molecular imaging method for evaluating liver regeneration capacity after ALPPS operation

Disclosed is a molecular imaging method for evaluating liver regeneration ability after ALPPS. The method includes steps of: 1) preparing a VX2 rabbit liver cancer model; 2) performing ALPPS for the VX2 rabbit liver cancer model; 3) synthesizing 18F-Fluoromethylcholine (18F-Methylcholine, 18F-FCH); 4) PET/CT imaging and data processing for .sup.18F-FCH. The disclosure is the first to propose the use of 18F-FCH PET/CT to monitor the proliferative capacity of residual liver, and further indirectly reflect the increased ability of cell membrane synthesis on the basis that 18F-FCH has higher choline metabolism in residual liver tissue, so that the liver regeneration ability after ALPPS is evaluated by the molecular imaging method, thereby providing important new ideas for the clinical selection of ALPPS to choose the best time for second-stage surgery.

System and method for cabinet radiography incorporating a gamma or other probe

It would be advantageous with the close quarters in breast procedure rooms to create a system and method incorporating 2 modalities utilized in breast intervention procedures for the diagnosis and verification for breast cancer. Systems for specimen radiography assist radiologists and surgeons in the detection and classification of abnormal lesions in medical images gleaned from breast biopsies/lumpectomies and a Gamma or other probe system with a sensor to detect radioactive, metallic/magnet, or RFID waves to help locate a lump or abnormality which were placed by an Interventional Radiologist. With the utilization of a dual modality machine, the physician can detect the abnormalities, remove the abnormalities, and verify that they have achieved a clean margin, currently 1 mm, from the cancerous or abnormal tissues. Currently it is believed that there is not a system or method utilizing both a Gamma or other probe and Radiography in a cabinet system.
