OBJECTIVE 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. MATERIAL AND METHODS We retrospectively evaluated 9 patients diagnosed of cancer or with suspected tumor disease who showed hypermetabolic lymph nodes in (18)F-FDG PET-CT....

A 17-year-old boy with hyperparathyroidism exhibited a large cyst in the left hemi-thorax on his chest X-ray. The cyst was identified as a hydatid cyst. He was referred for biphasic methoxy isobutyl isonitrile (MIBI) parathyroid scan. A discrete ectopic parathyroid was detected in the left upper mediastinum in addition to accumulation of the MIBI tracer in the cyst wall. Using radio-guided occu...

BACKGROUND Radio-guided occult lesion localization is a valid technique for the diagnosis of suspicious non-palpable lesions. Here we determine the feasibility of pre-operative localization of occult suspect non-palpable breast lesions using radio-guided occult lesion localization, as well as for identifying the sentinel lymph node. METHODS This is a descriptive study of data collected retros...

BACKGROUND The radioguided localization of occult breast lesions (ROLL) technique often utilizes iodinated radiographic contrast to assure that the local injection of (99m)Tc-MAA corresponds to the location of the lesion under investigation. However, for this application, this contrast has several shortcomings. The objective of this study was to evaluate the safety, effectiveness and technical ...

Radioguided surgery can be a useful technique in the localization of neuroendocrine tumors. It detects more and smaller lesions compared to pre-surgical imaging and intraoperative digital palpation by the surgeon. It detects residual lesions and also indicates the shortest access route to the lesion. Nevertheless, its use has not become widespread because of technical difficulties. There is a l...

Background: Breast screening programs and increased self-awareness has led to increased identification of early breast cancers. Up to 25% of mammographicaly identified lesions are nonpalpable, which require a precise technique to localize and excise completely. Radio-guided occult lesion localization (ROLL) is a technique, which uses hand held gamma probe to accurately localize and completely e...
