Over the past decade, computed tomography (CT) theory, techniques and applications have undergone a rapid development. Since CT is so practical and useful, undoubtedly CT technology will continue advancing biomedical and non-biomedical applications. In this outlook article, we share our opinions on the research and development in this field, emphasizing 12 topics we expect to be critical in the...

the advent of dual-modality pet/ct imaging has revolutionized the practice of clinical oncology, cardiology and neurology by improving lesions localization and the possibility of accurate quantitative analysis. in addition, the use of ct images for ct-based attenuation correction (ctac) allows to decrease the overall scanning time and to create a noise-free attenuation map (μmap). the near simu...

BACKGROUND Recent efforts have focused on reducing computed tomography (CT) imaging in children. Although published reports show variability in CT scanning for specific indications, an assessment of the effects of institutional factors (case-mix or hospital volume) on the rate of CT scanning for any indication is necessary to better understand variability across pediatric hospitals. METHODS D...

PURPOSE To investigate whether the multislice CT scanning protocols of head, chest and abdomen are adjusted according to patient's age in paediatric patients. MATERIALS AND METHODS Multislice CT examination records of paediatric patients undergoing head, chest and abdomen scans from three public hospitals during a one-year period were retrospectively reviewed. Patients were categorised into t...

Positron emission tomography/computed tomography (PET/CT) is an important tool to identify occult melanoma metastasis. To date, it is controversial which patients with primary cutaneous melanoma should have staging PET/CT. In this retrospective analysis of more than 800 consecutive patients with cutaneous melanoma, we sought to identify factors predictive of PET/CT positivity in the setting of ...

At the time this editorial was written, an extremely interesting loop was closing! Indeed, this text was written last after the invitation received in October 2012 and the proposal submitted in August 2013 for a Frontiers in Plant Science research topic (specialty: Plant Biophysics and Modeling) on " plant CT scanning, " the preliminary submission of abstracts in December 2013 and the seven pee...

A 16-year-old girl presented with intermittent left chest pain and breathlessness on exertion for last 4 months with one episode of haemoptysis. There has been loss of appetite and weight loss of 4 kg over a period of 1 month. A chest radiograph revealed a large mass like opacity with pleural effusion in the left lung field. Computerized Tomography scanning (CT scanning) and Positron Emission T...

84 ● M a r t 2 0 0 1 C omputed tomographic angiography (CTA) is a technique that has evolved in a rapidly changing interplay of hardware and software advances. CT scan times are becoming ever shorter, now allowing imaging of larger segments of arterial anatomy during circulation of the intravenous bolus of contrast material. Multidetector (or multislice) CT is the most recent dramatic advance t...

MATERIALS AND METHODS: Direct axial and coronal CT by using a conventional sequential scanning mode (140 kV, 220 mAs/section, 1.25-mm thickness, 1.25-mm increment, 16 0.625 mm collimation, the glabellomeatal line as a scanning baseline), a routine helical scanning mode (140 kV, 220 mAs/ section, 0.315 pitch, 0.67-mm thickness, 0.33-mm increment, 16 0.625 collimation, the orbitomeatal line as a ...
