Clinical and preclinical studies of cardiovascular calcification often require interpretation of images from histopathology, computed tomography, intravascular ultrasound, and positron emission tomography. To avoid potential pitfalls in biological inferences, investigators should know what happens to data in image processing algorithms, the limitations of cross-sectional images in studying mech...

Intracranial epidermoid cysts are generally located in the cerebellopontine and parasellar areas and appear hypo-dense on computed tomography and hypo-intense on T1-weighted magnetic resonance imaging. We report a case of an unusual epidermoid cyst of the cerebellopontine angle extending into the upper cervical canal that appeared hyper-dense on computed tomography scanning, hyper-intense on T1...

Coronary computed tomography (CT) enables noninvasive, highly diagnostic visualization of coronary artery stenosis. However, identifying culprit lesions in patients with multivessel coronary artery stenoses is difficult. Cardiac single photon emission computed tomography (SPECT) shows ischemic regions with high diagnostic accuracy, although evaluating the vascular territory supplied by each cor...

Objective: Multislice computed tomography is an emerging technology with the potential for non-invasive coronary investigation. The aim of this study was to evaluate the feasibility and limitations of multislice computed tomography in the detection of coronary artery disease. Patients and Methods: Multislice computed tomography was performed in symptomatic patients with atypical chest pain and ...

objectives: this study aimed to assess the effect of voxel size and object location in the field of view (fov) on diagnostic accuracy of cone beam computed tomography (cbct) for detection of simulated bone defects. materials and methods: in this in vitro study, bone defects were drilled in four sections of a dry human mandible. bone blocks were fixed on a platform parallel to the horizontal pla...

Quantitative software for the analysis and review of myocardial perfusion emission computed tomography images is an indispensable tool in the nuclear physician's evaluation of patients with known or suspected heart disease. The Corridor4DM (4DM) application (formerly known as 4DM-SPECT), developed at the University of Michigan Medical Center, is a quantitative software application providing aut...
