Preliminary Experience With Thallous Chloride Tl 201--Labeled Single-Photon Emission Computed Tomography Scanning in Head and Neck Cancer

Value of CT Thallium-201 SPECT Fusion Imaging over SPECT Alone for Detection and Localization of Nasopharyngeal and Maxillary Cancers

“…We have previously reported that 201 Tl uptake may be associated with the viability of esophageal cancer, and that its chemoradiotherapeutic effect can be evaluated with 201 Tl SPECT [6]. Thalium-201 SPECT has been reported to have a very high accuracy in the detection of head and neck cancers [7][8][9], which is consistent with our results. Therefore, 201 Tl SPECT may be useful in addition to established imaging techniques such as CT or MRI.…”

Pain as sign of recurrent disease in head and neck squamous cell carcinoma

“…Modern metabolic imaging techniques like photo emission tomography (PET) and single photo emission computed tomography (SPECT) seem to develop as a future additional tool in the search for an occult tumor recurrence with possibly higher accuracy rates based on tumor or metabolically specific isotopes. [11][12][13] Despite the promising developments of new sophisticated imaging systems, the clinical prognostic information remains an almost irreplaceable tool in judging patients as being at risk for the development of a recurrence. In this respect, implementation of the important prognostic information as tumor stage cannot be overemphasized.…”

Management Implications of Evaluating the N2 and N3 Neck After Organ Preservation Therapy

“…Physical examination can be unreliable, as persistent disease and radiation changes are often indistinguishable. Although newer imaging modalities may hold some promise in distinguishing radiation change from tumor, currently available imaging modalities often add little 8,9 …”
