CT Enterography: Principles, Trends, and Interpretation of Findings

CT enterography: concept, technique, and interpretation.

CT enterography is a new imaging modality that has distinct advantages over conventional CT, wireless capsule endoscopy, and barium examination. CT enterography is noninvasive and allows rapid mapping of disease activity before endoscopy and in cases where the endoscope cannot reach the diseased segment. CT enterography is readily available, is operator independent, and allows evaluation of ext...

CT enterography: principles, technique and utility in Crohn's disease.

CT enterography is a modification of conventional CT technique optimized for the evaluation of small bowel. This technique utilizes multidetector scanners with high spatial and temporal resolution; multiplanar reconstructions; and large volumes of enteric contrast to provide bowel distension. This article discusses the essential principles of the exam and its use in the evaluation of Crohn's di...

Computed tomography based attenuation correction in PET/CT: Principles, instrumentation, protocols, artifacts and future trends

  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 attenuat...

Denoising CT Enterography on GPU

CT enterography is a method of contrast enhanced diagnosis of small intestine from computed tomography examination. However, unlike the bones or other significant structures, automatic or semiautomatic examination of small intestine is almost impossible without the proper use of a denoising algorithm. We cannot wait for hours for a simple denoising algorithm in medical praxis, but current GPUs ...
