Pulmonary nodule detection in oncological patients - Value of respiratory-triggered, periodically rotated overlapping parallel T2-weighted imaging evaluated with PET/CT-MR.

Purpose: To prospectively evaluate the detection and conspicuity of pulmonary nodules in an oncological population, using a tri-modality PET/CT-MR protocol including a respiration-gated T2-PROPELLER sequence for possible integration into a simultaneous PET/MR protocol.

Methods: 149 patients referred for staging of malignancy were prospectively enrolled in this single-center study. Imaging was performed on a tri-modality PET/CT-MR setup and was comprised of PET/CT and 3T-MR imaging with 3D dual-echo GRE pulse sequence (Dixon) and an axial respiration-gated T2-weighted PROPELLER (T2-P) sequence.

Intra-individual comparison of PET/CT with different body weight-adapted FDG dosage regimens.

Background: 18F-2-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET)/ computed tomography (CT) imaging demands guidelines to safeguard sufficient image quality at low radiation exposure. Various FDG dose regimes have been investigated; however, body weight-adapted dose regimens and related image quality (IQ) have not yet been compared in the same patient.

Purpose: To investigate the relationship between FDG dosage and image quality in PET/CT in the same patient and determine prerequisites for low dosage scanning.

Spot scanning-based proton therapy for intracranial meningioma: long-term results from the Paul Scherrer Institute.

Background: To assess the long-term clinical results of spot scanning proton therapy (PT) in the treatment of intracranial meningiomas.

Patients And Methods: Thirty-nine patients with meningioma (histologically proven 34/39) were treated with PT between July 1997 and January 2010. Thirty-two (82.

Adult langerhans cell histiocytosis of bones : a rare cancer network study.

Langerhans Cell Histiocytosis (LCH) is an uncommon benign bone tumour typically seen in children. LCH of bones in adults has been reported as solitary cases. The aim of the current study is to analyze different treatment approaches and the role of radiotherapy (RT) in adult LCH.

Radiation recall dermatitis with soft tissue necrosis following pemetrexed therapy: a case report.

Introduction: Radiation recall dermatitis is a well known but still poorly understood inflammatory reaction. It can develop in previously irradiated areas and has been shown to be triggered by a variety of different drugs, including cytostatic agents. Pemetrexed may cause radiation recall dermatitis in pre-irradiated patients.
