AbstractA CT system with a tablet as mobile user interface and a wireless remote control for positioning and radiation release has recently been presented. Our aim was to evaluate the effects of a mobile CT examination workflow on the radiographers ’ performance compared to conventional examinations. A prototype of a radiation protection cabin was installed besides the gantry of a CT system. The CT system was equipped with a simplified user interface on a portable tablet and a mobile remote control. 98 patients with an indication for CT of t he chest were randomly assigned to examination using the mobile devices (stu...

The diagnosis of MALT lymphoma was made by pathological and immu...

We present two cases of diffusely decreased liver attenuation on post-mortem computed tomography (CT) which is lower than that on ante-mortem CT. Cases include a 37-year-old female whose cause of death was related to myelodysplastic syndrome (Case #1) and an 88-year-old female whose cause of death was related to malignant lymphoma (Case #2). We compared post-mortem CT (PMCT) liver attenuations with those on ante-mortem CT (AMCT). For Case #1, average AMCT values of the right/left liver were 46.1/50.0 Hounsfield Units (HU) 2 days ante-mortem and PMCT values of the right/left liver were 33.9/38.4 HU 3 hours post-mortem. For ...

JonasAbstractA posterior staphyloma is an outpouching of a circumscribed region of the posterior fundus and has been considered a hallmark of pathologic myopia. Occurring in highly myopic eyes, it is histologically characterized by a relatively abrupt scleral thinning starting at the staphyloma edge, a pronounced de-arrangement of scleral collagen fibrils and a marked choroidal thinning, which is the most marked at the staphyloma edge and which occurs in addition to the axial elongation-associ...

CONCLUSION: On the basis of this preliminary study, it appears that the use of a barrier membrane to cover the lateral bone window during maxillary sinus floor augmentation surgery with a lateral approach reduces the postoperative dislodgement of the bone graft throughout the sinus antrostomy and prevents the bone substitute particles penetrating within the buccal mucosa, which is related to postoperative morbidity.

DISCUSSION: In maxillary sinus floor elevations performed by the lateral approach, the size of the antrostomy did not affect the clinical and radiographic outcomes. PMID: 30521653 [PubMed - as supplied by publisher]
