Abstract. Breast cancer is one of the most common malignant neoplasms among women nowadays. Timely diagnosis basis for effective and successful treatment this disease. The existing classical methods X-ray examination (MG, ultrasound, MRI) play a major role in detection breast cancer, but some cases, can be difficult. Therefore, diagnostic performance scintimammography with specialized gamma cam...
Scientimammography (SMM) is a new non-invasive method of imaging breast tumors which in various studies the overall sensitivity of 83%-95.8% and specificity of 52%-95% is reported. The purpose of our study was to evaluate the usefullness of 99mTc-MIBI SMM in our environment in detecting breast cancer and in reducing the rate of biopsy. 65 patients aged 23-70 years were included in this st...
A 20-year-old man with right bundle branch block in recorded ECG was referred to our department. His physical examination was unremarkable. Transthoracic echocardiography showed a severe hypertrophy of the interventricular septum (22 mm)which contained multiple echo-free spaces of the vascular nature. A flow pattern suggestive to a coronary artery fistula into the left ventricle was recorded. T...
Cleaning validation, a requirement of the current Good Manufacturing Practices (cGMP) for Drugs, consists of documented evidence that cleaning procedures are capable of removing residues to predetermined acceptance levels. This report describes a strategy for the selection of the worst case product for the production of lyophilized reagents (LRs) for labeling with 99mTc from the Instituto de Pe...
A successful attempt at percutaneous transluminanl coronary angioplasty (PTCA) to relieve stenosis of the mid-portion of the left anterior descending artery was achieved in a 6-year 9-month old boy who had multiple coronary aneurysms and stenosis due to Kawasaki disease. Despite the progression of coronary stenosis he had been well except for the perfusion defect of the anterior wall of myocard...
Various endocrine manifestations are commonly described in myotonic dystrophy (MD), including primary hypogonadism, diabetes mellitus, and thyroid and parathyroid dysfunction. We describe a 46-year-old woman with a family history of MD with her son. She was diagnosed with cardiac arrhythmia and required the implantation of a pacemaker. She was noted to have a bilateral cataract. She complained ...
Results: In SPECT study visual analysis correlated extremely well with clinical features. Comparison of patient SPECT data with normal population showed significant hypoperfusion of lower limbs in terms of counts (P-value <0.001). Follow up of patients (N=12) showed significant improvement of muscle perfusion in nine patients while three patients showed no improvement. Comparison of follow up p...
PURPOSE The present a novel adenocarcinoma model in athymic mice. METHODS Seven athymic mice were used. Colon diversion and distal fistula were made. Adenocarcinoma cells were inoculated in the submucosa of fistula. Tumor growth was monitored daily. Scintigraphy with 99mTc-MIBI was performed to identify the tumor. RESULTS The model of distal colon cancer is feasible. Tumor detection was pos...
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...
