twenty-one patients with medullary thyroid carcinoma were studied prospectively with tc-99m (v) dmsa after surgery. pentavalent dmsa scintigram demonstrated abnormal uptake in 13 and equivocal uptake in 6 patients. finally, seven patients with surgical or other imaging documentation were selected for this paper. most of these patients were asymptomatic. six patients had hypercalcitonemia and se...

Unexpected findings on bone scintigraphy such as asymmetrical uptake in extremities may cause confusion for the diagnosis. The authors describe three cases of accidental intraarterial injection of Tc-(99m) methylene diphosphonate ((99m)Tc-MDP) on the antecubital region and discuss the findings and differential diagnosis.

A case of a woman aged 46 years with signs of rhabdomyolysis and acute renal failure is presented. Coxsackie serum test was positive. Increased uptake of Technetium-99m methylene diphosphonate (99mTc-MDP) by muscles of thighs and calves was observed. After 1 year no increased accumulation of radiotracer in the muscles was found.

skeletal metastasis is one of the most important disabling complications of the malignant diseases. as in general, the survival of patients with osteometastatic lesions is relatively long, an early diagnosis can lead to improve the patient’s life, both quantitatively and qualitatively, and prevent exacerbation of the disease and disabling complications. in this study, 22 patients with establish...

unilateral condylar hyperplasia is the main cause of mandibular asymmetry. radionuclide bone scanning is a useful procedure for functional evaluation of temporomandibular joint. in this study, 39 patients with normal bone scan and no facial asymmetry were studied. all patients were below 22 years of age. normal condylar uptake was determined in this group of patients. right & left condylar ...

UNLABELLED A 64-year-old male patient with small cell lung cancer underwent Fluorine-18 fluorodeoxyglucose (F 18 FDG) positron emission tomography (PET)/CT scan which revealed multiple F 18 FDG uptake in the spine, both humeri, ribs, pelvis and proximal long bones. There was no obvious lytic or sclerotic bone destruction accompanying these lesions on CT component of the study. After the patient...

Pigment villondular synovitis (PVNS) is a rare synovial condition. The nature of this disorder is usually characterized as benign; however, malignant transformation has also been reported. MRI is the diagnostic modality of choice in evaluating this entity, revealing low T1 and T2 weighted signals and blooming artifact on gradient echo sequences.  Three-phase 99mTc-MDP bone scan has b...

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...
