A radiologist was reviewing a tumor case in radsuite and noticed that the pixel value tool was displaying different values then the pet modality's software.To aid in the interpretation of pet images, the pixel value tool within the radsuite software can be used to view the absorption of an injected isotope in body tissue based on standardized uptake values (suv).The patient weight value is used for calculating the suv.If the patient weight is missing, the value is null.If a study with a patient weight value of null is viewed after a study for a different patient with a patient weight value greater than 0, the weight from the previous study will be used to calculate the suvs for the study with the null weight value.This may result in incorrect suvs.If other clinical factors are not available or taken into due consideration, incorrect suvs could potentially lead to overstatement or understatement of the effectiveness of a cancer treatment, or to a misdiagnosis of a cancer.
