In this paper, we provide assembly instructions for an easy-to-build experimental setup in order to gain practical experience with tomography. As such, paper can be seen as a complementary work excellent undergraduate-level mathematical textbooks concerned the basic principles of Since uses light tomographic imaging, objects investigated need transparent, such origami figures. Should reader wan...

Ronald L. Arenson, M.D., RSNA president, has noted that the Society’s annual meeting is approaching its second century with a new purpose and role to play in the practice of medicine. It will be incumbent on radiology professionals, he said, to constantly work at improving the analysis of medical images in a way that is meaningful to patients. “One of the key drivers is going to be whether or n...

ABSTRACTNeuroimaging allows noninvasive evaluation of the anatomy, physiology, and function of the brain. It is widely used for diagnosis, treatment planning, and treatment evaluation of neurological disorders as well as understanding functions of the brain in health and disease. Neuroimaging modalities include X-ray computed tomography (CT), magnetic resonance imaging (MRI), single photon emis...

Background and Aim: Bone density is of great assistance in the selection of the proper implant site. The present study aimed to assess the correlation between tissue densities in computed tomography (CT) and three different cone-beam computed tomography (CBCT) units. Materials and Methods: In this descriptive study, a radiographic phantom consisting of a transparent polymethyl methacrylate (PM...

This mage-based series comprises of a quiz pertaining to the identification of salient and important anatomical structures and landmarks expected to be seen at a given level on the computed tomography (CT). The representative image is followed by a series of images showing the examples of different commonly encountered pathological entities that can be seen at this level in a routine clinical p...

Here, we describe a patient with a history of colorectal cancer in whom 2-[18F]fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography ([18F]FDG PET/CT) was performed for the evaluation of response to therapy. [18F]FDG PET/CT showed a small residual disease in the rectum. In addition, multiple metabolically inactive soft tissue densities were d...
