Download or read book PET CT Atlas on Quality Control and Image Artefacts written by International Atomic Energy Agency and published by . This book was released on 2014 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Positron emission tomography/computed tomography (PET/CT), as any other imaging modality, is acceptable for routine clinical and research applications only if technical pitfalls can be avoided. Artefacts from incorrect or sub-optimal acquisition procedures should be recognized and, if possible, corrected retrospectively and the resulting image information interpreted correctly, which entails an appreciation of variants of the represented image information. This publication provides guidance on the physics and technical aspects behind PET and PET/CT image distortions. Cases are presented to provide nuclear medicine and radiology professionals with an assortment of examples of possible image distortions and errors in order to support a correct image interpretation. Nearly 70 typical PET and PET/CT cases, comprising image sets and cases, have been collected in this volume, all catalogued and augmented with explanations as to the causes of, and solutions to, each individual image problem. The atlas will prove useful to physicists, physicians, technologists, and service engineers in the clinical field.
Download or read book PET CT and Artefacts written by Katalin Nemeth and published by . This book was released on 2014 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Positron Emission Tomography (PET) is a very commonly used molecular and functional imaging method in the field of oncology for diagnosis, staging, follow-up and radiotherapy planning. Computed Tomography (CT) is used for attenuation correction and adding anatomical information. In this thesis, the basics of PET-CT imaging were explained, and possible artefacts were described and classified as PET-based, CT-based and attenuation correction based artefacts. Respiratory artefacts were discussed in the main part of the thesis. The underlying mechanisms (CT can be performed in a few seconds with respiratory hold technique, PET imaging is performed in 6-30 minutes normally with free breathing) were described. The literature research gave a review over respiratory artefacts and state of the art techniques to avoid or at least reduce them. In general, there are three different approaches: pre-reconstruction methods, motion corrections during reconstruction and post-reconstruction correction techniques. There are numerous technical devices used (e.g. impedance based, temperature based, video based, spirometry based) in the clinical practice, and other authors suggest software based solutions (e.g. gated + algorithm). These different possibilities were described and their advantages and disadvantages were shown. Especially for software based solutions there were only limited clinical data, but for most of the methods described here were existing clinical data (at least preliminary data) showing that reducing respiratory artefacts could result in higher rates of lesion detection (higher sensitivity of PET-CT) without a loss of specificity.*****Positron Emission Tomography (PET) is a very commonly used molecular and functional imaging method in the field of oncology for diagnosis, staging, follow-up and radiotherapy planning.
