Molecular Imaging could understanding disease or state the disease processes from the physiology and the biochemistry level. Not only it can improve the capability of disease diagnosis, but also it can discover the disease from molecule level. It's the real method of early diagnosis and preemptive therapy. Because of it's development and capacity, molecular imaging will be the development direction of Medical imageology, and lead to the biomedical model revolution.

In this paper the concept of molecular imaging is introduced, and its importance is addressed. Besides, the key points of molecular imaging are briefly reviewed from a view of engineering. Particular emphasis is given to the analysis of the function and the position of traditional medical imaging modalities in the era of molecular imaging. Finally a discussion is made for the further development of medical imaging modalities along the line of molecular imaging.

A retrospective study on 7 patients with close renal trauma was carried out. The preoperative and postoperative ultrasound found that the patients experienced the renal pedicular lesion. 7/7 patients were in stable condition, and experienced the urination with diluted blood or without blood. 7/7 patients had ultrasonic images of mass blood clot in the postperitoneal that push the kidney into the front. The CT scanner can suggest the renal pedicular lesion. If there was the renal pedicular lesion in the CT scanner image, it should implement renal angiography.

PURPOSE: This research aims at developing a PC-based spinal screw insertion simulation program and rapid prototyping spine models for correct placement of spinal screws. MATERIALS AND METHODS: We developed a surgical simulator on top of a 3-D medical imaging system V-worksTM (Cybermed, Inc.) and used Z-402 (Z Corporation) models made of hardened starch. RESULTS: The first phase is training surgeons using the simulation software. The trainees could simulate the insertion of spinal screws using the PC-based software. The second phase is a planning software to determine the ideal entry point and insertion angle using the multiplanar reconstruction images of spine CT. Finally, a rapid prototyping model of which the size is identical to the actual bone is produced for simulation surgery prior to the actual one. CONCLUSION: The system provides a tool for educating and training the beginners of spinal screw insertion, and also a pre-surgical simulation environment for planning the actual insertion surgery.

Fluorescence imaging now becomes an intraoperative navigation technique that gaining popularity in surgery and clinical research. However, at present, there is no mature and reliable method or other related guidance documents for the detection of fluorescence imaging performance. The performance analysis and quality supervision of products on the market could not be performed, which affects their clinical use and image quality. In this paper, a standard method of fluorescence imaging performance testing for fluorescence imaging system is proposed. Several kinds of fluorescence imaging performance parameters affecting fluorescence images are defined strictly. We also recommend scientific and feasible methods for their detections and analyses, which are verified by practical examples. This paper aims to provide a feasible reference standard for fluorescence performance evaluation.
