Background and Aims: With the increasing use of CT (Computed Tomoghraphy) scans in dentistry especially in the implantology, there may be significant increases in the radiation exposure and its risk. During the last year’s ConeBeam Computed Tomoghraphy (CBCT) has been introduced as an imaging modality for dentistry. The aim of this review article was to present comprehensive inform...
The accurate preoperative detection and intraoperative navigation afforded by imaging techniques have had significant impact on the success of liver cancer surgeries. However, it is difficult to achieve satisfactory performance in both diagnosis and surgical treatment processes using any single modality imaging method. Here, we report the synthesis and characteristics of a novel dual-modality m...
Abstract Fetal cholelithiasis is rare during pregnancy. Ultrasound examination in third trimester is the best diagnostic modality for detection of this condition. We report a case of 30- year old pregnant woman, at 36 weeks gestation, attending medical imaging center for routine obstetric ultrasound examination. Diagnosis of gallstones was made based on presence of multiple echogenic foci in...
skeletal involvement is the second most common site of metastases after lymph nodal metastases in patients with prostate cancer. the skeletal metastases from prostate cancer are osteoblastic in nature and show increased tracer avidity on the bone scan. focal tracer avid lesion in skeleton especially in skull requires the careful examination by further investigation. the patients with skull meta...
Many recent imaging genetic studies focus on detecting the associations between genetic markers such as single nucleotide polymorphisms (SNPs) and quantitative traits (QTs). Although there exist a large number of generalized multivariate regression analysis methods, few of them have used diagnosis information in subjects to enhance the analysis performance. In addition, few of models have inves...
UNLABELLED We developed a novel integrated quad-modality system that included 3 molecular imaging methods (PET, SPECT, and fluorescence molecular imaging [FMI]) and 1 anatomic imaging modality (CT). This system could study various biologic processes in the same animal using multiple molecular tracers. In addition to the technology development, we also discussed the optimization strategy of the ...
cardiovascular disease remains the principal cause of death in the modernized world. several novel noninvasive imaging techniques have been recently developed to improve diagnosis of cardiac and coronary disease. of these advances, multidetector computed tomographic (mdct) angiography has evolved most dramatically to transform computed tomography from a single-slice trans-axial modality to ...
