Objective Explore the optima scan parameters of screening colorectal cancer using low dose with 64-slice spiral CT in order to make it more consummate in clinical application.Materials and Methods 42 artificial polypoid diseases were placed with glue in a thoroughly cleaned porcine colon(overall length,150 cm) that was distented with air and submerged in a water [...]
PART I COMPARATIVE STUDY BETWEEN THE MAXIMUM INTENSITY PROJECTION OF MULTISLICE SPIRAL CT AND THE SMALL SHADOW EXAMINED BY TRADITIONAL HIGH KV RADIOGRAPHYObjective: to compare the reconstructed radiography of the maximum intensity projection (MIP) in coronal view of multislice spiral CT and the examination results from the patients with non-dusty lung in 0 stage by [...]
Part 1An experimental animal model of Myocardial ischemic:study of positron emission tomography, single photon emission computed tomography and pathologyObjective To compare 201T1 SPECT imaging for the assessment of myocardial viability with 18F-FDG PET imaging in pigs with chronic myocardial ischemic. Methods 9 animal models completed all examination successfully.201T1 SPECT imaging and 18F-FDG PET imaging were [...]
Objective: To analyze the technical characteristics of sliding multislice magneticresonance imaging （SMS-MRI）, and to evaluate the value of ovarian carcinomastaging by SMS-MRI.Methods: Fifteen patients with ovarian carcinoma were performed both multislice CT（MSCT） and SMS-MRI scan before operation. Scanning range included thoraciccavity, abdominal cavity and pelvic cavity （from superior aperture of thorax to bottomof pelvic）. Routine [...]
Part one:Establishment of the rabbit VX2 liver tumor model and evaluation of the characteristics in different growth period on MSCT perfusion imagingPurpose:To establish experimental rabbit VX2 liver model by implanting VX2 tumor cells into the rabbit liver, and to evaluate their perfusion parameter changes during different growth period.Methods:The VX2 tumor was passaged through successive subcutaneous [...]
