Leukemia is the most common childhood cancer and accounts for 30-40% of all malignancies. A retrospective review  was performed of the hospital records of 9 children, 6 boys and 3 girls, aged  from 2.5 to 15 years with ALL initially referred to Nemazee hospital Nuclear medicine center for whole body bone scanning between 2000 and 2002. Bone marrow pathology established ALL (L1) in two and ALL (...

The performance of most—if not all—gamma cameras on the market is satisfactory for static imag ing at low count rates. CT scanning, however, will reduce the need for such static studies, with bone scintigraphy as one of the few possible exceptions. In the future the main load will lie on dynamic func tional studies. Many such procedures—in particu lar radiospirometry, radiocardiography an...

Bone scintigraphy has some limitations in detecting bone lesions at the time of diagnosis since Tc99m MDP scintigraphy does not trace lesions lacking osteoblastic activity3. Tc99m Sestamibi (MIBI) has been proposed as a potential tracer in patients with multiple myeloma, as its increased uptake in the bone marrow has been reported as an indicator of myeloma activity4. It has been suggested to b...

BACKGROUND Cardiac transthyretin (ATTR) amyloidosis is a progressive and fatal cardiomyopathy for which several promising therapies are in development. The diagnosis is frequently delayed or missed because of the limited specificity of echocardiography and the traditional requirement for histological confirmation. It has long been recognized that technetium-labeled bone scintigraphy tracers can...

Thallium-201 (201Tl) redistribution scintigraphy might differentiate reversibly from nonreversibly asynergic myocardial segments and thus predict the response of these segments to coronary artery bypass grafting (CABG). To test this hypothesis, 25 consecutive patients undergoing CABG, preoperative stress-redistribution 201Tl scintigraphy, and both pre- and postoperative resting equilibrium radi...

Bone scintigraphy being a highly sensitive modality is useful in the detection of skeletal metastases in cancer patients. The procedure does not pose any radiation risks to the patients. To improve the specificity of the modality, proper patient selection is important. This article explores the application of bone scintigraphy in detection of metastatic cancer with an insight about patient sele...

Bone scintigraphy of metastatic lesion on 128 patients with prostatic cancer were classified according to the proposal by Soloway et al (Cancer, 61; 195-202, 1988). Since all patients received endocrine therapy, the response to therapy and survival were examined in relation to bone lesion. In extent of disease (EOD) 1, main metastatic lesions were located in the pelvis, lumbar spine, and with i...

Bacterial orbital cellulitis is an infection of the soft tissues behind the orbital septum. Cellulitis is seen as a poorly defined area of increased CT density or T2 signal intensity within the fat. There is an amorphous enhancement following contrast infusion. Radiolabeled leukocytes or granulocytes are now established widely as a means of localizing various forms of inflammatory disease and i...

thallium 201 whole body scintigraphy was performed in a 30 year old patient with diffuse osseous metastatic disease secondary to glioblastoma multiforme. multiple sites of thallium uptake correlated with the findings on serial bone scans and radiographs. bone biopsy of a lower lumbar vertebra confirmed that the metastases were of glial origin.

   A 36-year-old woman with right upper quadrant abdominal pain since three months previously and no other significant medical history was referred for evaluation of an abdominal mass. Upon clinical examination, a large palpable mass in the mid -upper abdominal area was noted. Abdominal ultrasound and spiral CT-scan showed a large hepatic mass in the left liver lobe. ...
