BACKGROUND Differentiated thyroid cancers (DTC) often form metastases in neck lymph nodes, lungs and bones. Other metastases--to the brain, kidneys, skin and liver are rare. Liver metastases of DTC occur in the terminal phase of the disease and predominantly do not accumulate radioiodine. Functional (accumulating radioiodine) metastases are very rare. MATERIAL AND METHODS In an 85 year old pa...

BACKGROUND Phytoestrogens are plant-derived natural molecules having some bone forming and bone substituting effects. In the present study, the role of phytoestrogens on bone healing was investigated in a rabbit fracture model. METHODS Twenty-two New Zealand white rabbits with right tibia fracture were divided into two groups randomly. The plant derived extract of Vitex agnus-castus L. (Verbe...

Fig. 2 A 41-year-old man who suffered from pain in several joints for more than 10 years was referred for a bone scintigraphy. The patient was treated with non-steroidal anti-inflammatory drugs, but this treatment regimen did not result in a reduction of symptoms. Upon completion of the physical examination, no remarkable findings were noted. All routine laboratory tests were normal. The images...

Mastocytosis is a rare, heterogeneous disease of complex etiology, characterized by a marked increase in mast cell density in the skin, bone marrow, liver, spleen, gastrointestinal mucosa and lymph nodes. The most frequent site of organ involvement is the skin. Cutaneous lesions include urticaria pigmentosa, mastocytoma, diffuse and erythematous cutaneous mastocytosis, and telangiectasia macula...

Skeletal metastases are clinically significant because of associated symptoms, complications such as pathological fractures and their profound significance for staging treatment and prognosis. Detection of bone metastatic lesions allows radiation therapy or surgical interventions to prevent pathological fractures from disabling the patients. High sensitivity of bone scanning in determining the ...

The appearance of a hot kidney on bone scintigraphy is rare and can be seen due to various factors. In our clinic, we observed hot kidney appearance in two patients to whom technetium-99m methylene diphosphonate (Tc-99m MDP) whole body scan has been performed: a young male adult at the age of 18 who was diagnosed with acute lymphocytic leukemia with a presumptive diagnosis of avascular necrosis...

(99m)Tc-Methylene diphosphonate (MDP) triple phase bone scintigraphy (BS) has a role in early diagnosis of Kienbock's disease, especially when the X-ray is negative. Early diagnosis can result in prompt management of the patient since wrist pain in older individuals due to aging may go unnoticed or be due to other diagnoses with the production of greater damage and eventually a worse prognosis....

Bone scan was performed a 77 years old man with prostatic carcinoma. The planar 3h 99mTc-methylenediphosphonate (MDP) whole-body bone scan did not reveal skeletal metastases. However, on the anterior view, unexpected, large, round shaped activity in the liver projection was noted (Panel A). Further investigation disclosed that the patient had been operated for hepatic hemangioma thirty years ag...

Renal scintigraphy can provide the valuable split renal function which is not obtainable by other non-invasive measurements. This study was designed to investigate the feasibility of the assessment of relative renal function with Tc-MDP as compared with renal imaging radiotracers used for that purpose. Differential renal functioni.e the contribution of percent that each kidney makes to global r...
