Whilst FDG PET/CT performs well in the conventional imaging paradigm of identifying, counting and measuring tumour extent, a key paradigm change is its ability to non-invasively measure glycolytic metabolism. For interpretation, it is important to be aware of benign variants that demonstrate high glycolytic activity, and pathologic lesions which may not be FDG-avid, and understand the physiologic and biochemical basis of these findings. This encompasses how we display, threshold intensity of images and sequence our review, which are essential for accurate interpretation. In the manuscript we detail our approach to reviewing and reporting a PET/CT study using the most commonly used radiotracer, FDG. Interpretation requires integration of the metabolic and anatomic findings provided by the PET and CT components which transcend the knowledge base isolated in the worlds of nuclear medicine and radiology, respectively.

Cine Tracer Whats Series Will Address

Future articles in this series will address the use of other tracers pertinent to other cancers. In this article, we detail our approach to reviewing a PET/CT study using the most commonly used tracer, FDG. Whilst there is a wealth of literature addressing the utility of PET in a large array of malignancies, the art of how to review and interpret PET/CT is generally acquired like an apprentice and not well addressed in the literature. This is a modality with many patterns of structural, physiologic and biochemical abnormalities that transcend the boundaries previously isolated in the worlds of nuclear medicine or radiology in characterising pathological conditions, particularly including cancer.
Detailed discussion of acquisition parameters is beyond the scope of this review but includes preparation of diabetic patients, strategies to minimise brown fat activation, as well as prescription of the extent of the field-of-view and the positioning of the patient to address the clinical question. What is Cine Tracer Cine Tracer is one of the popular Simulation, Early Access games developed by Matt Workman and was published by Cinematography Database.Patient preparation is important in acquiring good quality studies and it is the responsibility of the PET specialist to ensure that appropriate protocols are in place to prevent non-diagnostic or suboptimal studies.

This also aids presentation of findings to referrers and patients.The primary data from PET has been traditionally displayed on a linear grey scale. Correct and consistent windowing is key to avoid both over- and under-interpretation of findings and to maintain the consistency required for accurate comparison of multiple studies. These are the stand-alone PET data, the CT and the fused PET/CT images. Optimal windowing of PET imagesIn any PET/CT study there are three discrete image sets that require display. This varies widely according to local practice and our approach is discussed in further detail later in this manuscript.An important aspect of interpretation is assessment of the technical adequacy of the study and ideally should be done before the patient leaves the department to enable repeat acquisition of any critical regions inadequately assessed on the initial examination. It is also important to determine the methodology to be used for CT acquisition.
Use of a colour scale is required for superimposition of functional images over the CT. By maintaining a reasonable spectrum of grey shades for display of normal tissues it is possible to detect faint lesions in areas of low background activity, such as the lung.Our preference is to have the most intense voxels in the normal liver appearing just below the middle of the grey scale range, which will be a light to mid-grey (Fig. Consequently, the intensity of normal tissues should be within the lower-to-middle portion of the dynamic range while the upper range used to demonstrate the range of intensities that might exist in pathological processes characterised by high glycolytic activity. The lower threshold of this display should be set at zero (white) while the upper threshold needs to be manipulated to obtain consistent display of physiological and pathologic uptake.
This will usually be apparent by virtue of increased relative uptake in the spleen, which is generally marginally less intense than the liver. However, this may be counteracted by deposition of fat in the liver in obese subjects. This means that more FDG is available for uptake in other tissues, including the liver. This is because adipose tissue contributes to the weight correction of administered activity, which is used for SUV calculation, but does not itself take up FDG. This corresponds to an upper SUV window threshold of 8–10 and will usually achieve an appropriate contrast, except in very large patients in whom this may make the liver too dark.
However, using the liver as a reference enables consistent windowing of images over a series of time-points within and between individuals and compensates for variations that might be caused by inaccuracies in SUV measurement between scans, issues related to dose calibration errors, extravasation of dose, different uptake periods or technical differences if rescanned on a different type of PET/CT device. Our practice of thresholding the grey and colour scale to liver as detailed above results in similar image intensity to a fixed upper SUV threshold of 8 to 10. This can be detected visually if there is marked discrepancy between liver and spleen intensity, although with sarcoidosis or lymphoma both can be increased. It is, however, inappropriate to threshold for liver uptake if it is not deemed normal due to diffuse malignant infiltration, sarcoidosis, or fatty infiltration.
Standard thresholds provide a good representation of the extent of disease but using a higher upper threshold to display the images can help to identify the regions of likely transformation or different disease biology and can aid biopsy site selection (Fig. Follicular lymphoma, in which most lesions can have a SUV max in excess of 10 but regions of high-grade transformation with corresponding values of >15, is a particular case in point. This is particularly important in diseases where there can be considerable heterogeneity in disease. Of the limbs) that do not encompass the liver.Since some disease processes can have extremely high SUV values, it may be necessary to increase the upper threshold to appreciate the dynamic range of glycolytic activity. The same SUV threshold as that used for the whole body study should be applied when additional separate series are acquired (e.g.
We often see studies, particularly from practices that have more experience with CT than PET, that have clearly had the threshold altered to render them red, or not, depending on whether the reader considers them more, or less, likely to be malignant based on the CT characteristics. Clearly, this is an oversimplification, but it enables one to eyeball the PET image and decide if the uptake is of low, moderate or high metabolic activity.It should, however, be noted that this can be a dangerous scale to use if there isn’t a disciplined and consistent use of the threshold setting principles detailed above since it is easy to “dial” lesions in and out. Like a traffic light, we teach our referrers that these spectrums usually represent benign, equivocal and pathological findings, respectively. It is also a psychologically intuitive scheme with blue-green shades being cool colours whereas yellow-orange colours denote caution and reds, danger.
