Markedly elevated111 In labeled leukocyte activity suggestive of acute osteomyelitis was observed in a region of a composite mandibular allograft that was photon deficient on 99mTc MDP bone scintigraphy. This finding was later confirmed by surgical pathology. The patient was treated with intravenous antibiotics and returned two months later with persistent bone infection. The foHow-up thr...

Purpose: A standard imaging protocol for monitoring and predicting the response to Peptide Receptor Radionuclide Therapy (PRRT) has not been established yet. The aim of this study was to evaluate the response to PRRT by quantitative SPECT-CT and assess the value of SPECT-CT over routine planar scintigraphy in predicting the outcome

The patient with a history of bone pain and muscle weakness, was thought to have oncogenic osteomalacia as a result of biochemical investigations and directed to Nuclear Medicine Department for a whole-body bone scintigraphy and 111In-octreotide scintigraphy. There was no focal pathologic tracer uptake, but generalized marked increase in skeletal uptake on bone scintigraphy. Octreotide scintigr...

Correlation of Radiologic Tests in the Diagnosis of Brucellosis with Osteoarticular Involvement Background. The most common complication of brucellosis is musculoskeletal system involvement. Bone and joint involvement in brucellosis may present as mainly sacroiliitis and spondylitis. In this study, we aimed to evaluate the correlation of plain X-rays, bone scintigraphy, and contrast-enhanced ma...

Introduction: The optimal imaging time of a radionuclide scintigraphy is the time at which the organ of interest has the maximum uptake of the injected radionuclide. This study was performed to investigate the maximum uptake time of 99mTc-DMSA in rat renal scan. Methods: Renal scintigraphy was performed with 3 mCi of 99mTc-DMSA. Planar images were acquired every 20 minutes for 8 hours post-inje...

Multiple myeloma (MM) is a clonal B-lymphocyte neoplasm of terminally differentiated plasma cells. Imaging modalities which allow the recognition of the effects of myeloma cells on the skeletal system have been utilized for a long time. Herein, we represent a patient with generalized osteoporosis and hypercalcemia, who was referred for parathyroid scan, in whom the widespread bone marrow techne...

introduction: appendicitis is one of the most common surgical emergencies. in spite of the relatively high rate of negative appendectomy, as a result of miss diagnosis, uncertainty of diagnosis still continues to challenge physicians. the objective of this prospective study was to investigate the role of 99mtc-ubiquicidin (ubi) scintigraphy in the diagnosis of acute appendicitis and to compare ...

A 16 years female who had end-stage renal disease on 2-month continuous ambulatory peritoneal dialysis (CAPD) presented with perineal pain 4 days before admission. The physical examination revealed bilateral labial edema. Peritoneal scintigraphy was requested after infusing 2 L peritoneal dialysate with direct administration of 370 MBq (10mCi) technetium-99m diethylenetriamine pentra-acetic aci...

introduction: bone metastases are the most common cause of cancer-related pain in various primary malignant tumors, most often, breast and prostate. 188re-hydroxyethylidene diphosphonate (188re-hedp) is a new and less expensive bone seeking radiopharmaceutical with favorable physical characteristics of the radionuclide such as short half life of 16.9h, maximal β energy of 2.1 mev with a 15% γ-c...
