PURPOSE To assess the clinical value of computed tomography (CT) and magnetic resonance imaging (MRI) image fusion with 11C-acetate (AC) positron emission tomography (PET) imaging for detection and exact location of clinically occult recurrences. PATIENTS AND METHODS Fifty prostate cancer patients with elevated/increasing serum prostate-specific antigen levels after radical therapy underwent ...
UNLABELLED The aim of this study was to assess the value of 99mTc-hexakis2-methoxyisobutylisonitrile (MIBI) scintigraphy in patients with clinical and radiologic features of primary or metastatic musculoskeletal tumors. METHODS The scintigraphic findings for 84 patients were compared with the surgical and histologic findings. Each patient underwent three-phase bone scanning with 99mTc-methyle...
Extraosseous accumulation of technetium-99m-methyl diphosphonate (99mTc-MDP) on bone scan is not common. This phenomenon is often attributed to abnormality of calcium metabolism and has been reported in a variety of conditions including metabolic diseases and malignancies. A five years old boy is presented here, who was admitted to the pediatric emergency suffering from fatigue, respiratory sym...
سابقه و هدف: با توجه به درصد بالای جمعیت دختران نوجوان در ایران و شیوع بالای اضافه وزن و چاقی آنها، و بار اجتماعی-اقتصادی چاقی، تشخیص رژیم غذایی مطلوبی که از افزایش وزن جلوگیری کند، ضروری می باشد. مطالعه حاضر با هدف تعیین ارتباط تبعیت از الگوی رژیم مدیترانه ای (mediterranean dietary pattern- mdp) با اضافه وزن و چاقی در دختران نوجوان شهر تهران انجام شد. مواد و روش ها: در این مطالعه مقطعی، 280 دخ...
A nine-month old male child presented with low-grade fever, loose stools and facial puffiness. Clinically patient was otherwise normal except for a firm liver on palpation. The laboratory tests revealed hypoproteinemia (both albumin and globulin) and iron deficiency anemia. Differential diagnosis considered were: 1. Nephrotic syndrome, 2. Cystic fibrosis (in view of recurrent diarrhea and respi...
The authors present a comparison of the findings for thallium-201 (Tl-201), Tc-99m MAG3 and Tc-99m MDP in subacute and chronic radiation nephritis in a 9-yr-old boy who was treated by radiation therapy for alveolar rhabdomyosarcoma of the left chest wall by a radiation port that partially included the left kidney. Tl-201 imaging three and six months later showed a cortical defect in the left ki...
Whole body bone scan with Technetium-99m MDP (methylene diphosphate) can detect bony lesions due to altered osteoblastic activity.Non-physiologic or increased radiotracer uptake in the bony structures of patients with a history of malignant diseases is usually interpreted as being suspicious of bone metastasis. It is extremely important to properly distinguish false positive sites of Tc-99m MDP...
A 14-year-old child was diagnosed with primitive neuroectodermal tumor (PNET) of pelvis. Baseline 99mTc-methtylene diphosphonate (MDP) bone scintigraphy done to know the extent of the disease, although of suboptimal quality, revealed involvement of right hemipelvis (A, arrowhead) (Fig. 1). Also, there was a focus of increased radiotracer uptake in the occipital bone (B, arrow). Since the patien...
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...
