Factors influencing the pattern and intensity of myocardial 18F-FDG uptake in oncologic PET-CT imaging

Introduction:Myocardial 18F-FDG uptake is highly variable in oncologic whole body 18F-FDG PET/CT studies, ranging from quite intense to minimal distribution. Intense or heterogeneous myocardial 18F-FDG uptake is undesirable as it may interfere with the visual or quantitative evaluation of tumoral invasion and metastases in pericardium, myocardiu...

Global challenges in oncologic imaging

Even as many cancers have been transformed from fatal to chronic diseases in developed countries, global cancer incidence and mortality have been rising [1]. While imaging is an essential tool in cancer care, the guidelines for its use are neither sufficient nor widely recognized. The needs for imaging equipment and training vary around the globe but are generally vast. Addressing these needs w...

Oncologic Imaging: Spine and Spinal Cord Tumors 978-981-287-702-4 Kang Oncologic Imaging: Bone Tumors

Dynamic optical projection of acquired luminescence for aiding oncologic surgery.

Optical imaging enables real-time visualization of intrinsic and exogenous contrast within biological tissues. Applications in human medicine have demonstrated the power of fluorescence imaging to enhance visualization in dermatology, endoscopic procedures, and open surgery. Although few optical contrast agents are available for human medicine at this time, fluorescence imaging is proving to be...

Dual-energy CT in oncology: technical principles and clinical prospects

Learning objectives • Dual-energy CT (DECT) can amply contribute to a more efficient workflow in oncologic imaging. • DECT has the potential to reduce the radiation dose and to replace classical dual-phase protocols. • DECT improves oncologic imaging with improved tumour detection and opens up avenues for tissue differentiation and characterisation. • DECT allows for optimised and repeatable th...

Preparation, distribution, stability and tumor imaging properties of [62Zn] bleomycin complex in normal and tumor-bearing mice

Backgrounds: Bleomycin (BLM) has been labeled with radioisotopes and widely used in therapy and diagnosis. In this study BLM was labeled with [62Zn] zinc chloride for oncologic PET studies. Materials and methods: The complex was obtained at the pH=2 in normal saline at 90 ° C in 60 min. Radio-TLC showed an overall radiochemical yield of 95-97% (radiochemical purity > 97%). Stability of complex ...
