Nasolacrimal system aeration on computed tomographic imaging: effects of patient positioning and scan orientation
PURPOSE To determine the impact of patient positioning and scan orientation on the appearance of air in the nasolacrimal drainage system on computed tomography (CT) imaging, and the repeatability of the observations. METHODS This was a retrospective analysis of CT images for 92 patients. RESULTS Air was found to be present more fully in the upright-position group as compared with the supine...
متن کاملComputed tomographic imaging of anomalous coronary arteries.
Coronary Arteries To the Editor: Ropers et al1 present a series of images demonstrating that the proximal course of anomalous left main and left anterior descending coronary arteries originating from the right sinus of Valsalva can be visualized by electron beam computed tomography. We are writing to communicate that more widely available, retrospectively gated multislice computed tomography (M...
متن کاملCerebral computed tomographic angiography scan delay in subarachnoid hemorrhage.
CONTEXT Computed tomographic angiography (CTA) is widely applied in the evaluation of cerebral vessels. Contrast enhancement in cerebral CTA without care or test bolus is not always sufficient for high-quality images. AIMS Evaluation of the possibilities of calculation of scan delay for cerebral CTA in case of subarachnoid hemorrhage (SAH), based on clinical data of a patient and to find out ...
متن کاملGastrointestinal stromal tumors: computed tomographic features and prediction of malignant risk from computed tomographic imaging.
BACKGROUND Gastrointestinal stromal tumors (GISTs) are specific, generally Kit (CD117)-positive, mesenchymal tumors of the gastrointestinal tract encompassing a majority of tumors previously considered gastrointestinal smooth muscle tumors. Our aim was to characterize the computed tomographic findings and predict malignant risk from computed tomography for the evaluation of GISTs. METHODS The...
متن کاملPatient perceptions of computed tomographic imaging and their understanding of radiation risk and exposure.
STUDY OBJECTIVE We describe patient perceptions of computed tomography (CT) and their understanding of radiation exposure and risk. METHODS This was a cross-sectional study of acute abdominal pain patients aged 18 years or older. Confidence in medical evaluations with increasing levels of laboratory testing and imaging was rated on a 100-point visual analog scale. Knowledge of radiation expos...
