67Ga-subtraction scan was found to be useful and a promising new method for the pre-treatment evaluation of the patient with Hodgkin’s disease or non-Hodgkin’s lymphoma. The scan appeared to be most accurate in the neck, chest, and axillary regions. It appears to offer a means of increasing the accuracy of evaluating the abdomen, the para-aortic and pelvic regions. It may be a useful method for follow-up to detect recurrences. It was an easily performed, safe, non-invasive test, well tolerated and accepted by patients.
Recently a new method was described, the 67Ga subtraction scanning method. 67Ga accumulates in neoplastic and inflammatory tissue. The subtraction method was applied for evaluating 38 patients with Hodgkin's disease and non-Hodgkin's lymphoma. The preliminary experiences are described. It was found that the diagnostic accuracy is comparable to that of 67Ga scanning. The subtraction method offers potential improvement of the accuracy for equivocal scans, but further technological refinement is needed before the method can be widely applicable.
Die 67Ga-Subtraktions-Szintigraphie stellt eine niitzliche und vielver-sprechende neue Methode für die Beurteilung eines Patienten mit Morbus Hodgkin oder Non-Hodgkin-Lymphom vor dem Behand-lungsbeginn dar. Die Szintigraphie ist im Hals-, Thorax- und Achsel-bereich am genauesten. Sie scheint auch die Möglichkeit zu bieten, die Genauigkeit bei der Beurteilung des Abdomens, der paraaortalen Region und des Beckens zu erhöhen. Sie ermöglicht ferner die Auffindung von Rezidiven bei Nachuntersuchungen. Der Test ist leicht durchführbar, ungefährlich und für den Patienten nicht belastend.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
