The spleen is an intraperitoneal organ which is composed of a trabecular network of vessels, nerves and lymphatic tissue. Anatomical variants with regard to the shape and accessory spleens are seen. Systemic lymphatic diseases often result in splenomegaly.

Contrast CT image generation model using CT image of PET/CT
2018 IEEE Nuclear Science Symposium and Medical Imaging Conference Proceedings (NSS/MIC), 2018Contrast CT imaging is a useful method to highlight structures such as blood vessels and tissue. The aim of this study was to generate contrast enhanced CT image for defining region of blood vessels and tumor from PET/CT image using deep learning approach. The deep learning approach in this study was based on conditional generative adversarial network (

Evolutionary CT image reconstruction
Proceedings of 1st International Conference on Conventional and Knowledge Based Intelligent Electronic Systems. KES '97, 2002An evolutionary algorithm for reconstructing CT gray images from projections is presented; the algorithm reconstructs two-dimensional unknown images from four one-dimensional projections. A Laplacian constraint term is included in the fitness function of the genetic algorithm for handling smooth images, and the evolutionary process reconstructs images ...

Method for transforming CT images for attenuation correction in PET/CT imaging
Medical Physics, 2006A tube‐voltage‐dependent scheme is presented for transforming Hounsfield units (HU) measured by different computed tomography (CT) scanners at different x‐ray tube voltages (kVp) to linear attenuation values for attenuation correction in positron emission tomography (PET) data reconstruction. A Gammex 467 electron density CT phantom was imaged using a

Trends in oncological CT imaging: clinical application of multidetector-row CT and 3D-CT imaging
International Journal of Clinical Oncology, 2006Computed tomography (CT) plays an essential role in oncological imaging as the modality of screening for malignancies, mapping out the treatment strategy at staging, assessing response to the treatment, and following up patient outcome after the treatment.

Fast data acquisition imaging technologies such as modern computed tomography (CT) allow contrast agents to be used as tracers and nuclear medicine methodology may be used to derive a variety of functional/physiological information from dynamic CT. This article describes the theoretical basis and some practical applications of this idea including the ...

CT Myocardial Perfusion Imaging
American Journal of Roentgenology, 2015OBJECTIVE. CT myocardial perfusion imaging is rapidly becoming an important adjunct to coronary CT angiography for the anatomic and functional assessment of coronary artery disease with a single modality. Existing techniques for CT myocardial perfusion imaging include static techniques, which provide a snapshot of the myocardial blood pool, and dynamic

CT imaging of craniofacial malformations
Neuroimaging Clinics of North America, 2003Because of its superior depiction of bone detail, CT is a useful tool in the characterization of CF deformities and presurgical planning. Modern CT scanners and workstations provide 2D techniques such as multiplanar reformats and 3D techniques, such as MIP and volume renderings, which may be used effectively in the diagnosis and management of patients ...

Adenocarcinoma of the pancreas: CT imaging
Radiologic Clinics of North America, 2002CT currently plays a vital role in pancreatic cancer staging. Continued advancements in computers, scanner technology, and 3D software have improved CT detection of smaller masses and staging. In particular, the introduction of MDCT and real-time 3D volume-rendering software have greatly improved the visualization of the pancreas and adjacent ...

CT and CT Nuclear Imaging of the Heart
2007Over the past decades, conventional coronary angiography has been the only accepted ‘gold standard’ method for clinical imaging of coronary artery disease (CAD). However, coronary angiography is costly, causes patient discomfort, and is associated with a small but distinct procedure-related morbidity (1.5%) and mortality (0.15%). Moreover, the accuracy
