Purpose. The aim of this study was to compare the diagnostic accuracy of 2-[fluorine-18] fluoro-2-deoxy-Dglucose positron emission tomography ( 18 F-FDG-PET) and computed tomography (CT) with PET/CT in the detection of liver metastases during tumour staging in patients suffering from colorectal carcinoma for the purposes of correct surgical planning and follow-up. Materials and methods. A total of 467 patients underwent a PET/CT scan using an iodinated contrast medium. We compared images obtained by the single PET scan, the single CT scan and by the fusion of the two procedures (PET/CT). specificity, enabling modification of patient treatment, but it is also a unique, high-profile procedure that can produce cost savings.

“…However, it is challenging to obtain good-quality images of PET and SPECT due to highly noisy measurements and various artifacts. For the past few decades, hardware and software for nuclear medicine have been improved dramatically so that better image quality was able to be achieved and better utilization of molecular images became possible potentially for better diagnosis and therapeutic monitoring, sometimes with high-resolution anatomical information such as X-ray computed tomography (CT) or magnetic resonance imaging (MRI) from hybrid scanners such as PET-CT, SPECT-CT, and PET-MR [3][4][5].…”

“…The development of combined PET-CT or SPECT-CT made it possible to routinely obtain well-aligned CT with PET or SPECT in clinics, respectively [3,9]. Recently, combined PET-MR has been actively researched so that MR images can be obtained simultaneously with PET [5,10].…”

“…Anatomical images such as high-resolution CT or MR can be used together with molecular images such as low-resolution PET or SPECT to take advantage of multi-modal imaging for diagnosis and therapeutic monitoring [3,4,10,22]. Aligned anatomical images not only affect clinical decisions by providing fused images with molecular images but also play important roles in image reconstruction algorithms, which bring further advances of nuclear medicine software for improved image quality of PET or SPECT.…”

PET and SPECT are important tools for providing valuable molecular information about patients to clinicians. Advances in nuclear medicine hardware technologies and statistical image reconstruction algorithms enabled significantly improved image quality. Sequentially or simultaneously acquired anatomical images such as CT and MRI from hybrid scanners are also important ingredients for improving the image quality of PET or SPECT further. High-quality anatomical information has been used and investigated for attenuation and scatter corrections, motion compensation, and noise reduction via post-reconstruction filtering and regularization in inverse problems. In this article, we will review works using anatomical information for molecular image reconstruction algorithms for better image quality by describing mathematical models, discussing sources of anatomical information for different cases, and showing some examples.
