background: technetium-99m radioisotope is the backbone of any nuclear medicine institute. this radioisotope is acquired by the elution of molybdenum-99/technetium-99m generator which emits 141 kev gamma ray and having 6.04 hour half-life. occasionally the contents of molybdenum-99 may mix up with elute, which may affect image quality and patients may receive higher doses than recommended. this...

OBJECTIVE A subset of parathyroid adenomas contains a relative overabundance of oxyphil cells that are capable of greater technetium Tc 99m sestamibi tracer uptake and retention than other cell types. We examined whether the presence of oxyphil cells augments the sensitivity of technetium Tc 99m sestamibi preoperative localization and whether the histologic findings of a lesion could be predict...

Nitrogen-containing biphosphonates are a group of medications that are increasingly used in the management of Paget's disease, fibrous dysplasia, osteoporosis, multiple myeloma and metastatic prostate or breast cancer bone disease. On 2004 it was established that nitrogen-containing biphosphonates may induce jaw osteonecrosis and since then, a substantial number of publications has supported th...

Paget's disease of bone is a common metabolic bone disease in most of the European countries. The disease has distinct geographical distribution being rare in Asia. We report Paget's disease in a 70 years old Pakistani male who presented with history of pain in right leg with difficulty in walking for the last 5 months. Plain X-ray raised suspicion of Paget's disease of bone. Technetium-99m MDP...

OBJECTIVE To report a rare case of extramedullary hematopoiesis (EMH) with an asymptomatic intrapelvic mass in a patient with thalassemia major. CLINICAL PRESENTATION The patient presented with a pelvic mass discovered by ultrasonography before undertaking laparoscopic cholecystectomy for gallstones. Technetium-99m MDP bone scan failed to differentiate EMH from malignancy. A fine-needle aspir...

OBJECTIVE At present, metastatic bone involvement is usually assessed using bone scintigraphy, which has a high sensitivity but a poor specificity. The objective of our study was to compare the sensibility of the 2-deoxy-2-[18F] fluoro-d-glucose positron emission tomography/computed tomography (F-18 FDG PET/CT) for the detection of bone metastasis in patients with non-small-cell lung cancer (NS...

Multiple benign osteolytic lesions are very hard to differentiate from disseminated bone metastasis. Whole-body bone scintigraphy (WBBS) with technetium-99m methylene diphosphonate (Tc-99m MDP) demonstrates multiple lesions with increased uptake in any bone involved. Even combined with medical history and multiple imaging results, such as MRI and CT, the clinical diagnosis of metastasis lesion ...

A number of people suffered rhabdomyolysis caused by eating crayfish in China and the final diagnosis was a rare disease called Haff disease. In this study, we present a 26 years old man with a history of severe muscular soreness for whole body after eating crayfish and this status lasted for about 3 months. Blood analysis showed significant increase in serum creatine kinase and lactate dehydro...
