Department of Radiology

Radionuclide bone imaging is one of the most commonly performed nuclear medicine procedure around the world and characterized by its high sensitivity and relatively low specificity. False positive findings on a bone scan are very common; however, dense uptake over unilateral ossified anterior longitudinal ligament appearing as single thyroid lobe on a bone scan has not been described in the literature.

Abstract

OBJECTIVE:

Pelvic lymph node dissection (PLND) is the gold standard procedure for nodal staging in prostate cancer (PC) but less commonly used due to its invasiveness. More commonly computerized tomography (CT) and magnetic resonance imaging (MRI) are used although these have limited sensitivities and specificities. The aim of this study was to find out the correlation between higher scrotal uptake ratio (SUR) of (99m)Tc-methylene diphosphonate (MDP) on bone scan and pelvic nodemetastasis in patients with PC at high risk for nodal metastasis.

METHODS:

This was a retrospective study which included 68 biopsy proven newly diagnosed PC patients who had …
