Positron emission tomography/computed tomography guided percutaneous biopsies of Ga-68 avid lesions using an automated robotic arm
ConclusionPET/CT-guided molecular biopsy using Ga-68 labelled radiotracers is feasible and can be performed safely and accurately with a high-diagnostic yield. It is helpful in accurately staging the disease when tracer-avid isolated distant lesion evident on imaging and highly practical in patients with previous inconclusive sampling.
CONCLUSIONS: Fresh frozen homologous bone seems to have a good healing pattern and to be a successful and steady grafting material for the treatment of maxillary ridge atrophy. It might be considered a valid alternative to autologous bone in sinus floor augmentation procedures. PMID: 31822046 [PubMed - in process]
ConclusionIn Revolution CT, beam hardening artifacts were reduced in reduced-iodine VMI at lower energy levels compared to Discovery CT, contributing to better image quality.

Conclusions: Herniation of TMJ into the EAC is a rare condition, but can be encountered in the clinic at any time. This literature review could be helpful in the diagnosis and treatment of TMJ herniation into the EAC.
Conclusions: Poor cavity obliteration, a high rate of revision surgery and difficult differentiation between recurrent cholesteatoma and granulation tissue in CT scan was observed.
CONCLUSION: Flexible videoureterorrenoscopy and Holmium laser for the management of intrarenal stenosis are highly effective and safe with the advantages of less perioperative complications, less invasiveness and being an outpatient procedure compared to percutaneous surgery.

Conclusion: The development of LRSS pneumatization affects the removal rate of CS tumors in PAs. Preoperative analysis of LRSS development should be considered when planning EES against PA with CS invasion. PMID: 31819816 [PubMed]
SummaryColorectal cancer is the third most common and the third most lethal cancer disease in the western world. As most patients undergo treatment with curative intent at initial diagnosis, postoperative surveillance protocols have been established with the primary aim to detect possible disease recurrence in an early resectable stage. Various international guidelines recommend an intensive surveillance protocol over a 5-year time period. These guidelines are based on the reported significant benefit regarding overall patient survival, and on the observation that 90% of recurrences occur within the first 5 year...
In 1981, the Computed Tomography Dose Index (CTDI) was proposed as a method to estimate the absorbed dose to a standard plastic phantom to compare the radiation delivered to the phantom from two different CT scanners . Although this dose estimate to a specific phantom was not intended to be an estimate of patient dose, it was incorrectly used to estimate dose to patients of varying size from newborns to large adults. This error resulted in estimates of abdominal CT patient doses to newborns that were less than half the actual dose  and subsequent development of CT radiographic protocols that delivered more than doubl...
DiscussionThe examination of the different slices and the application of different filters represent a promising tool both for the education of students/residents and for an improved informed consent by the patients.
