Two female patients presented with multiple radiolucent lesions noted on panoramic radiography. Cone-beam computed tomography (CBCT) scans confirmed “punched-out” affecting the skull.

BACKGROUND Several scoring systems for cervical disc and facet joint degeneration, using radiography or computed tomography, have been developed and tested for reliability. However, definitions of disc height and facet joint space narrowing vary. To our knowledge, no study has reported quantitative data for normal radiologic values of the cervical spine in the Korean population. The purpose of ...

BACKGROUND A large variety of imaging techniques is an integral part of modern medicine. Introducing radiological imaging techniques into the dissection course serves as a basis for improved learning of anatomy and multidisciplinary learning in pre-clinical medical education. METHODS Four different imaging techniques (ultrasound, radiography, computed tomography, and magnetic resonance imagin...

The impact of digitalization on the average glandular doses in 49 mammographic units participating in the Flemish Breast Cancer Screening Program was studied. Screen-film was changed to direct digital radiography and computed radiography in 24 and 25 departments respectively. Average glandular doses were calculated before and after digitalization for different PMMAphantom thicknesses and for gr...

In this study we evaluate the clinical image quality of a computed radiography system for different tube voltages. Images of anthropomorphic phantoms were produced and the quality of the images was evaluated using visual grading analysis (VGA) by a group of experienced radiologists. Two different X-ray examinations were investigated: chest PA and pelvis AP. The exposure conditions were set so t...

Twenty-one limbs of bovine cadavers (42 digits) were exposed to interdigital cassetteless imaging plate using computed radiography. The radiographic findings included exostosis, a rough planta surface, osteolysis of the apex of the distal phalanx and widening of the laminar zone between the distal phalanx and the hoof wall. All these findings were confirmed by computed tomography. The hindlimbs...
