The aim of this study was to evaluate the potential of iterative reconstruction (IR) in chest computed tomography (CT) to reduce radiation exposure. The qualitative and quantitative image quality of standard reconstructions with filtered back projection (FBP) and half dose (HD) chest CT data reconstructed with FBP and IR was assessed. ⋯ • Iterative reconstructions allow for image noise and artifact reduction.• Comparable image data can thus be attained even at 50 % radiation dose.• Diagnostic confidence remains unaffected.

In patients with peritoneal carcinomatosis (PC), cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is an evolving therapeutic approach with curative intention. The differentiation between posttherapeutic findings after HIPEC and relapse of PC is challenging. We evaluated the diagnostic value of F-18-FDG-PET/CT in patients with relapse of PC after HIPEC. ⋯ • Imaging of recurrent PC after HIPEC is challenging due to posttherapeutic tissue alterations.• The extent of recurrent PC after HIPEC is systematically underestimated by F-18-FDG PET/CT.• F-18-FDG PET/CT provides improved sensitivity for recurrent PC compared to contrast-enhanced CT.• The correlation of the extent of recurrent PC depicted by F-18-FDG PET/CT and surgical exploration is better than that of contrast-enhanced CT and surgical exploration.

Determining whether implantation of an expandable titanium mesh cage (Osseofix® system) is a successful and safe minimally invasive therapy for osteoporotic and tumorous vertebral compression fractures (VCFs). ⋯ • The Osseofix® system is well suited for stabilizing osteoporotic and tumorous VCFs.• It is a safe and effective procedure without cement leakage and with a low complication rate.• The procedure is an interesting alternative to established cement augmentation procedures.

Pneumoperitoneum (PP) is a severe finding in emergency departments. Its quick and correct diagnosis is indispensable for the further treatment of patients. The aim of this study was to analyze the clinical value of abdominal ultrasound performed with a modern hand-carried ultrasound (HCU) device as well as with a high-end ultrasound (HUS) system in the diagnosis of PP in patients with acute abdominal pain. ⋯ 1. Pneumoperitoneum (PP) is a severe finding in emergency departments. 2. Hand-carried (HCU) and high-end (HUS) ultrasound systems can be helpful in detecting PP. 3. Abdominal radiography (AR) and multidetector computed tomography (MDCT) are superior in detecting PP. 4. HCU and HUS can accelerate the triage of patients. 5. HCU and HUS can be helpful when making decisions regarding the necessity of further examinations.
