CT angiography of the aorta using 80 kVp in combination with sinogram-affirmed iterative reconstruction and automated tube current modulation: Effects on image quality and radiation dose.
The objective of this study was to evaluate image quality and radiation dose of a CT angiography (CTA) protocol using 80 kVp in combination with iterative reconstruction and automated tube current modulation. ⋯ Low-dose CTA of the aorta using 80 kVp with iterative reconstruction enables a significant dose reduction of up to 50% compared with a 100 kVp protocol in patients with a BMI below 32 kg/m(2) while diagnostic image quality is maintained.

Using positron emission tomography (PET) response criteria in solid tumours (PERCIST) 1.0 for evaluation of 2'-deoxy-2'-[18F] fluoro-D-glucose-PET/CT scans to predict survival early during treatment of locally advanced non-small cell lung cancer (NSCLC).
The demand for early-response evaluation with 2'-deoxy-2'-[18F] fluoro-D-glucose (F-18-FDG) positron emission tomography combined with whole body CT (PET/CT) is rapidly growing. This study was initiated to evaluate the applicability of the PET response criteria in solid tumours (PERCIST 1.0) for response evaluation. ⋯ PERCIST 1.0 is readily implementable and highly comparable with visual evaluation of response using early F-18-FDG-PET/CT scanning for locally advanced NSCLC patients. In spite of variations in parameters affecting F-18-FDG uptake, evaluation of F-18-FDG-PET/CT during treatment with PERCIST 1.0 is shown to separate non-responders from responders, each with statistically significant differences in both OS and PFS.

Radiology in the Christchurch earthquake of 22 February 2011: Challenges, interim processes and clinical priorities.
The Canterbury earthquake of 22 February 2011 initiated a mass casualty event for Christchurch Hospital, which suffered damage itself, and faced logistical difficulties in continued operation. Radiology was part of the hospital-wide response. This paper reviews the radiology department response and surveys opinions of emergency doctors to provide an overview of events of the day and thoughts regarding any potential future response. ⋯ Although resources were limited, a diagnostic radiology service remained operational. The Christchurch experience reinforces the need for disaster planning and rehearsal of plans.
