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 ...

PURPOSE To compare MR with thallium-201 scintigraphy in the follow-up of patients who have undergone thyroidectomy and modified radical neck dissection for differentiated thyroid cancer. METHODS Both MR imaging and 201Tl scintigraphy were performed in 39 patients after surgery for differentiated thyroid cancer. Ten patients did not have recurrence; 29 patients had 51 recurrent tumors in the n...

the correlation of vesicoureteral reflux (vur), urinary tract infection (uti) and renal scarring is well known. several risk factors for renal parenchymal lesions have been reported previously. we determine the incidence of renal parenchymal damage and outcome in the siblings of children with primary vur. a total of 96 siblings of patients with vur, were evaluated with direct voiding cystograph...

The role of various radionuclide investigations, including parathyroid scintigraphy, bone scintigraphy and serum parathormone estimations in the diagnosis of primary hyperparathyroidism is reviewed briefly. The initial experience with the dual isotope (Tl-201; Tc-99m) subtraction scintigraphy for the preoperative localization of parathyroid adenomas is presented (JPMA 37 : 237, 1987).

A 70-year-old man with complicated cruris fracture, treated with an arthrodesis and skin transplantation, complained about persistent pain of the right ankle and skin rashes. Bone and leukocyte scintigraphy were performed because osteomyelitis was suspected. Bone scintigraphy showed abnormal uptake in the ankle. Leukocyte scintigraphy showed only multiple hot spots in the soft tissue. A cutaneo...

we present a 55-year old male patient who was subjected to whole body skeletal scintigraphy for metastatic work up of urinary bladder cancer. whole body 99mtc-methylene diphosphonate (mdp) skeletal scintigraphy was performed. that revealed no skeletal metastasis in the entire body skeleton and normally visualized left kidney with empty right renal fossa. additionally tracer activity collected i...

Introduction: This study was launched to evaluate the sensitivity and specificity of 99mTc-Ciprofloxacin to distinguish infection foci induced by staphylococcus aureus and inflammation lesions induced by carrageenan in the rat foot in comparison with 67Ga-Citrate scintigraphy. Methods: The labeling and quality control of 99mTc-Ciprofloxacin kits have been perfo...

We investigated the clinical impact of breast scintigraphy acquired with a breast specific γ-camera (BSGC) in the diagnosis of breast cancer (BC) and assessed its incremental value over mammography (Mx). A consecutive series of 467 patients underwent BSGC scintigraphy for different indications: suspicious lesions on physical examination and/or on US/MRI negative at Mx (BI-RADS 1 or 3), characte...

Sternal non-union is a severe complication of sternotomy closure following open heart surgeries. Healing problems typically occur in 0.3% to 5% of patients. Technetium-99m methylene diphosphonate (99mTc-MDP) bone scintigraphy has been used to assess bone nonunion to predict the healing response for proper management.  In this report, we present the case of a marked sternal nonunio...

Testicular scintigraphy has been well validated in the evaluation of patients with suspected testicular torsion and provides an accurate evaluation of testicular perfusion at the lime of imaging. However, the presence of normal or increased perfusion to the testis does not definitively exclude the necessity for surgical intervention. A case of intermittent testicular torsion, with a revie...
