... strength up to 3.0 T deliver promising image quality concerning anatomicalresolution and contrast but critical features are the sensitivity to susceptibility andchemical shift effects both creating artefacts. Methods: The 3.0 T MRI-Scanner (Siemens‘Trio’) was analyzed and compared to a Siemens Magnetom...

... Abstract Objective: In order to further optimize the surgical technique with the CO 2 laser instapes surgery, a scanner system was used to obtain a footplate perforation of 0.5-0.6mmwith only one laser application (‘one-shot’ stapedotomy). Study Design: 240 patients withotosclerosis were...

... Abstract Whole-slide imaging (WSI) is the digitization of glass slides allowing users to remotely examine, share, and analyze digital slides using computer monitors instead of microscopes. Since WSI scanners have become commercially available, many clinical and non-clinical applications have...

... Abstract Flexible bronchoscopy (FB) is the only method that permits real-time direct visualization and dynamic evaluation of the tracheobronchial system. Multidetector computed tomography (MDCT) scanners can generate accurate 2-dimensional (multiplanar reformation) and 3-dimensional...

... MRI (iMRI) DBS if the scanner used is located in radiology, or intraoperative MRI DBS if the scanner is located in the operating room. The principles are the same regardless of the magnet location, but to be truly MR-guided the scanner must be of a high enough field strength to visualize the target...

... and Methods Technical Considerations Due to the particular design of positional MRI scanners, several technical problems have to be solved in order to visualize the cerebral venous blood outflow system. First of all, positional MRI scanners are not based on a superconductive magnet; hence...

... scanners with field strengths of 1.5 or 3 Tesla allows the examination of the entire human body in an acceptable scan time and we can now make use of the excellent spatial resolution of this modality for examination of all body regions in the clinical setting. A reliable imaging modality enabling...

..., or scarring. The severity of pain, on a scale of 1–10, is reported relatively strong: 6–10. The pain seems to hit suddenly and also disappears as soon as the scanning terminates, or when patients leave the static magnetic field of the scanner. All but one case occurred in 1.5-tesla (T) MRI scanners, and one...

..., but also the percentage of total tumor excisions. Intraoperative MRI provides an immediate feedback to the surgeon and is thus a valuable quality control for pituitary surgery. It also allows the acquisition of data sets for precise intraoperative navigation. However, the MRI scanners are heavy...

... systems integrating a SPECT camera with an X-ray CT scanner are used. Roughly one third of patients with diagnostically unclear foci of radioiodine accumulation will benefit from the use of SPECT/CT, also in terms of therapeutic management. SPECT/CT has, therefore, become the gold standard of nuclear...

... Abstract The responsibility for safe ultrasound applications has been devolved to the user with the introduction of displayed safety indices on the scanner screen. It is therefore essential that the mechanisms of interaction of the ultrasound beam with the tissue being interrogated are properly...

... computed tomography (CT) scanners and magneticresonance imaging (MRI) must be performed. Inaccuraciesshould then be quantified through systematic combinationof MRI and CT in the radiosurgery planning system.Topography of petrous structures such as cochlea, vestibulumand facial nerve canal should be visible...
