PURPOSE: Assessment of crestal bone levels around implants is essential to monitor success and health. This is best accomplished with intraoral radiographs exposed at 90 degrees to the long axis of the implant, but this can be challenging to achieve clinically. Radiographic paralleling devices produce orthogonal radiographs but traditionally have required access to the implant body for each exposure. This study was conducted to determine if use of the Precision Implant X-ray Locator (PIXRL), a radiographic paralleling device that indexes the implant at the time of surgical placement, can produce orthogonal radiographs of dental implants more accurately than traditional radiologic techniques for assessing crestal bone levels...

Gafchromic films have been applied to X-ray dosimetry in diagnostic radiology. To correct nonuniformity errors in Gafchromic films, X-rays in the double-exposure technique can be replaced with ultraviolet (UV)-A rays. Intensities of the incident and transmitted UV-A rays were measured. However, it is unclear whether the chemical color change of Gafchromic films affects the UV-A transmission intensity. Gafchromic EBT3 films were suitable to be used in this study because non-UV protection layers are present on both sides of the film...

INTRODUCTION: Ultrasound (US) is the imaging modality of choice for staging the axilla prior to surgery in patients with breast cancer (BC). High pathological complete response rates in the axilla after NACT mean a more conservative approach to surgery can be considered. Radiological re-staging is important in this decision making. After the presentation of results from ACOSOG Z1071 in December 2012, formal ultrasound re-assessment of the axilla after primary therapy was specifically requested in our institution...

In penetrating injuries, woods are known to be difficult to detect with radiological imaging studies, because the wood density are known to be extremely close to the value of air on CT. Adjustment of CT window and reconstruction of a 3D image from CT images allowed us to more accurately distinguish wood from air and to find the fragment of the wooden chopstick. It is particularly useful in transorbital penetrating injury.
