Comparative Study
MRI-guided and CT-guided cervical nerve root infiltration therapy: a cost comparison.
To evaluate and compare the costs of MRI-guided and CT-guided cervical nerve root infiltration for the minimally invasive treatment of radicular neck pain. ⋯ Cervical nerve root infiltration using MRI guidance is still about twice as expensive as infiltration using CT guidance. However, since it does not involve radiation exposure for patients and personnel, MRI-guided nerve root infiltration may become a promising alternative to the CT-guided procedure, especially since a further price decrease is expected for MRI devices and MR-compatible disposables. In contrast, ultrasound remains the less expensive method for nerve root infiltration guidance.

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.

The purpose of this study was to find out whether pneumothorax detection and exclusion is superior in expiratory digital chest radiography. ⋯ • Basal pneumothoraces during inspiration demonstrate a greater width than during expiration. • There is statistically no difference between inspiration/expiration for the diagnosis of pneumothorax. • An image taken during inspiration is recommended to confirm or rule out a pneumothorax.
