%X <B>OBJECTIVE: </B>The aim of this study was to evaluate the usefulness of ROLL technique (Radioguided Occult Lesion Localization) as a verification method of suspicious lesions not related to breast disease found in PET-CT studies.<BR><B>METHODS: </B>We retrospectively evaluated 9 patients diagnosed of cancer or with suspected tumor disease who showed hypermetabolic lymph nodes in (18)F-FDG PET-CT. Subjects underwent diagnostic testing for evaluation of treatment response in lymphoma (3), suspected recurrence in other tumors (3) or biopsy guide (3). The study group consisted of 4 women and 5 men, age range 25-72 years. ROLL technique was performed in surgically accessible lesions (supraclavicular region, lateral cervical, axillary and inguinal) with an intralesional injection of (99m)Tc-albumin macroaggregates guided by ultrasound the day before surgery. A scintigraphic study confirmed the focal tracer deposit and absence of skin contamination. During surgery, a gamma probe and portable gammacamera were used to locate lymph nodes.<BR><B>RESULTS: </B>Surgical localization of radiolabeled lymph nodes was achieved in all cases with minimally invasive surgery and few postoperative complications. Histological study resulted in five tumor involvement (3 lymphoma, 1 germ cell tumor and 1 neuroendocrine carcinoma) and confirmed the existence of four false-positives in PET-CT study (1 sarcoidosis and 3 reactive follicular hyperplasia).<BR><B>CONCLUSIONS: </B>The ROLL technique proved to be a useful and relatively simple method for the study of no breast lesions suspicious of malignancy in PET-CT study.
