INTRODUCTION The spinal cord is poorly visualized on CT images but is well visualized in MRI images. However, implants used for spinal stabilization can produce artifacts on the MRI images which can interfere with identification of the cord. CT myelography in conjunction with CT simulation helps to clearly delineate the cord. MATERIALS AND METHODS CT simulation was done in a patient with vert...

central granular cell odontogenic tumor) cgcot) of the jaw is an exceedingly rare benign odontogenic neoplasm with 35 reported cases in the literature. among these, very few studies have focused on the cone-beam ct features of cgcot. here, we report a case of an asymptomatic cgcot in a 16-year-old girl and focus on the cone-beam ct features. only 36 cases of this lesion, including this one, hav...

PURPOSE Attenuation correction with an X-ray CT image is a new method to correct attenuation on SPECT imaging, but the effect of the registration errors between CT and SPECT images is unclear. In this study, we investigated the effects of the registration errors on myocardial SPECT, analyzing data from a phantom and a human volunteer. METHODS Registerion (fusion) of the X-ray CT and SPECT ima...

Lung cancer is a fatal disease that takes numerous lives every year around the world. However, detecting this in its initial stages can help save of people. CT imaging best technique used for field medical sciences. It by doctors but it hard examiners to decipher and recognize through computer-assisted tomography scan images. Hence, Computer-aided diagnosiswill be very supportive identify cance...

CT images with body weight loading are desired for preoperative planning on TKA surgery. In our proposed method, we perform stress analysis by the finite element method (FEM) for bone mesh structure by generating CT images, and we estimate an ideal standing position of the loaded state (referred to as deformed CT images of the ideal standing position). We also compare the deformed CT image with...
